Cisco IOS Software Packaging
The Enterprise Services image supports all Cisco Catalyst 4500E Series software features based on
Cisco IOS Software, including enhanced routing.
The IP Base image supports Open Shortest Path First (OSPF) for Routed Access, Enhanced Interior
Gateway Routing Protocol (EIGRP) "limited" Stub Routing, Nonstop Forwarding/Stateful Switchover
(NSF/SSO), and RIPv1/v2. The IP Base image does not support enhanced routing features such as BGP,
Intermediate System-to-Intermediate System (IS-IS), Internetwork Packet Exchange (IPX), AppleTalk,
Virtual Routing Forwarding (VRF-lite), and policy-based routing (PBR).
The LAN Base image complements the existing IP Base and Enterprise Services images. It is focused
on customer access and Layer 2 requirements and therefore many of the IP Base features are not
required. The IP upgrade image is available if at a later date you require some of those features
Starting with Cisco IOS Release (3.3.0SG or 15.1(1)SG), support for IP SLAs and NSF have been
extended from Enterprise Services to IP Base.

Cisco IOS XE to Cisco IOS Version Number Mapping
Cisco IOS XE to Cisco IOS Version Number Mapping
As Table 7 shows, each version of Cisco IOS XE has an associated Cisco IOS version:
Table 7 Cisco IOS XE to Cisco IOS Version Number Mapping
Upgrading the System Software
If you are upgrading to Cisco IOS XE Version 3.4.0SG and are planning on using VSS, you must upgrade
your ROMMON to IOS Version 15.0(1r)SG7. Otherwise, you must upgrade your ROMMON to at least
IOS Version 15.0(1r)SG2.
Be aware that you can upgrade a ROMMON image either through a console or telnet.
If dual supervisors are present, first upgrade your software to Cisco IOS XE 3.2.0SG or higher, then
upgrade your ROMMON to IOS Version 15.0(1r)SG7 to avoid an uplinks issue (CSCtj54375).
Identifying an +E Chassis and ROMMON
When supervisor engine 1 (sup1) is in ROMMON and supervisor engine 2 (sup2) is in IOS, only sup2
can read the idprom contents of chassis’ idprom. Chassis type is displayed as “+E” in the output of the
show version command. Conversely, sup1 can only display the chassis type as “E.”
When both sup1 and sup2 are in ROMMON, both engines can read the chassis’ idprom. Chassis type is
displayed correctly as “+E” in the output of the show version command.
When both sup1 and sup2 are in IOS, both engines can read the chassis’ idprom. Chassis type is
displayed correctly as “+E” in the output of the show version command.
Limitations and Restrictions
This section list the limitations and restrictions for the current release of Cisco IOS software on the
Catalyst 4500E series switch.
•Starting with Release IOS XE 3.3.0SG and IOS 15.1(1)SG, the seven RP restriction was removed.
•The WS-X4712-SFP+E module is not supported in the WS-C4507R-E or WS-C4510R-E chassis
and does not boot. This module is supported in the WS-C4503-E, WS-C4506-E, WS-C4507R+E,
and WS-C4510R+E chassis.

Release Notes for the Catalyst 4500E Series Switch, Cisco IOS XE Release 3.4.xSG
OL-27990-04
Limitations and Restrictions
•More than 16K QoS policies can be configured in software. Only the first 16K are installed in
hardware.
•Adjacency learning (through ARP response frames) is restricted to roughly 1000 new adjacencies
per second, depending on CPU utilization. This should only impact large networks on the first
bootup. After adjacencies are learned they are installed in hardware.
•Multicast fastdrop entries are not created when RPF failure occurs with IPv6 multicast traffic. In a
topology where reverse path check failure occurs with IPv6 multicast, this may cause high CPU
utilization on the switch.
•The SNMP ceImageFeature object returns a similar feature list for all the three license levels (LAN
Base, IP Base, and EntServices). Although the activated feature set for a universal image varies
based on the installed feature license, the value displayed by this object is fixed and is not based on
the feature license level.
•Standard TFTP implementation limits the maximum size of a file that can be transferred to 32 MB.
If ROMMON is used to boot an IOS image that is larger than 32 MB, the TFTP transfer fails at the
65,xxx datagram.
TFTP numbers its datagrams with a 16 bit field, resulting in a maximum of 65,536 datagrams.
Because each TFTP datagram is 512 bytes long, the maximum transferable file is 65536 x 512 = 32
MB. If both the TFTP client (ROMMON) and the TFTP server support block number wraparound,
no size limitation exists.
Cisco has modified the TFTP client to support block number wraparound. So, if you encounter a
transfer failure, use a TFTP server that supports TFTP block number wraparound. Because most
implementations of TFTP support block number wraparound, updating the TFTP daemon should fix
the issue.
•A XML-PI specification file entry does not return the desired CLI output.
The outputs of certain commands, such as show ip route and show access-lists, contain
non-deterministic text. While the output is easily understood, the output text does not contain strings
that are consistently output. A general purpose specification file entry is unable to parse all possible
output.
Workaround (1):
While a general purpose specification file entry may not be possible, a specification file entry might
be created that returns the desired text by searching for text that is guaranteed to be in the output. If
a string is guaranteed to be in the output, it can be used for parsing.
For example, the output of the show ip access-lists SecWiz_Gi3_17_out_ip command is this:
Extended IP access list SecWiz_Gi3_17_out_ip
10 deny ip 76.0.0.0 0.255.255.255 host 65.65.66.67
20 deny ip 76.0.0.0 0.255.255.255 host 44.45.46.47
30 permit ip 76.0.0.0 0.255.255.255 host 55.56.57.57
The first line is easily parsed because access list is guaranteed to be in the output:
<Property name="access list" alias="Name" distance="1.0" length="-1" type="String"
/>
The remaining lines all contain the term host. As a result, the specification file may report the
desired values by specifying that string. For example, this line
<Property name="host" alias="rule" distance="s.1" length="1" type="String" />
will produce the following for the first and second rules
<rule>
deny
37
Release Notes for the Catalyst 4500E Series Switch, Cisco IOS XE Release 3.4.xSG
OL-27990-04
Limitations and Restrictions
</rule>
and the following for the third statement
<rule>
permit
<rule>
Workaround (2):
Request the output of the show running-config command using NETCONF and parse that output
for the desired strings. This is useful when the desired lines contain nothing in common. For
example, the rules in this access list do not contain a common string and the order (three permits,
then a deny, then another permit), prevent the spec file entry from using permit as a search string,
as in the following example:
Extended MAC access list MACCOY
permit 0000.0000.ffef ffff.ffff.0000 0000.00af.bcef ffff.ff00.0000 appletalk
permit any host 65de.edfe.fefe xns-idp
permit any any protocol-family rarp-non-ipv4
deny host 005e.1e5d.9f7d host 3399.e3e1.ff2c dec-spanning
permit any any
The XML output of show running-config command includes the following, which can then be
parsed programmatically, as desired:
<mac><access-list><extended><ACLName>MACCOY</ACLName></extended></access-list></mac>
<X-Interface> permit 0000.0000.ffef ffff.ffff.0000 0000.00af.bcef ffff.ff00.0000
appletalk</X-Interface>
<X-Interface> permit any host 65de.edfe.fefe xns-idp</X-Interface>
<X-Interface> permit any any protocol-family rarp-non-ipv4</X-Interface>
<X-Interface> deny host 005e.1e5d.9f7d host 3399.e3e1.ff2c
dec-spanning</X-Interface>
<X-Interface> permit any any</X-Interface>

•When attaching a existing policy-map (that is already applied to a control-port) to another
front-panel port, the following message displays:
The policymap <policy-map name> is already attached to control-plane and cannot be
shared with other targets.
Workaround: Define a policy-map with a different name and then reattach. CSCti26172
•If the number of unique FNF monitors attached to target exceeds 2048 (one per target), a switch
responds slowly:
Workarounds:
–
Decrease the number of monitors.
–
Attach the same monitor to multiple targets. CSCti43798
•ciscoFlashPartitionFileCount object returns an incorrect file count for bootflash:, usb0:, slot0:,
slaveslot0:, slavebootflash:, and slaveusb0:.
Workaround: Use the dir device command (for example, dir bootflash:) to obtain the correct file
count. CSCti74130
•If multicast is configured and you make changes to the configuration, Traceback and CPUHOG
messages are displayed if the following conditions exist:
–
At least 10K groups and roughly 20K mroutes exist.
38
Release Notes for the Catalyst 4500E Series Switch, Cisco IOS XE Release 3.4.xSG
OL-27990-04
Limitations and Restrictions
–
IGMP joins with source traffic transit to all the multicast groups.
This is caused by the large number of updates generating SPI messages that must be processed by
the CPU to ensure that the platform is updated with the changes in all the entries.
Workaround: None. CSCti20312
•With traffic running, entering clear ip mroute * with larger number of mroutes and over 6 OIFs will
cause Malloc Fail messages to display.
You cannot clear a large number of mroutes at one time when traffic is still running.
Workaround: Do not clear all mroutes at once.
CSCtn06753
•Although you can configure subsecond PIM query intervals on Catalyst 4500 platforms, such an
action represents a compromise between convergence (reaction time) and a number of other factors
(number of mroutes, base line of CPU utilization, CPU speed, processing overhead per 1 m-route,
etc.). You must account for those factors when configuring subsecond PIM timers. We recommend
that you set the PIM query interval to a minimum of 2 seconds. By adjusting the available
parameters, you can achieve flawless operation; that is, a top number of multicast routes per given
convergence time on a specific setup.
•Energywise WOL is not “waking up” a PC in hibernate or standby mode.
Workaround: None. CSCtr51014
•The ROMMON version number column in the output of show module command is truncated.
Workaround: Use the show version command. CSCtr30294
•IP SLA session creation fails randomly for various 4-tuples.
Workaround: Select an alternate destination or source port. CSCty05405
•The system cannot scale to greater than 512 SIP flows with MSP and metadata enabled.
Workaround: None. CSCty79236
•When sup1 is in ROMMON and sup2 is in IOS, only sup2 can read the SEEPROM contents of the
following chassis components:
–
chassis
–
fan-tray
–
clock-module
–
power-supplies
–
mux-buffer for each linecard slot
–
linecards
On sup1, when the sprom read .. command is entered for any of the above components, the
SEEPROM contents are displayed as all “0”s.
When sup1 and sup2 are both in ROMMON (or both in IOS (SSO state)), they can read all
SEEPROMs.
•On the following linecards running IOS XE Release 3.2.3:
–
10/100/1000BaseT Premium POE E Series WS-X4648-RJ45V+E (JAE1348OY52)
–
4 Sup 7-E 10GE (SFP+), 1000BaseX (SFP) WS-X45-SUP7-E (CAT1434L0G4)
the following restrictions apply:
–
Sub-interfaces are not supported on 1 Gigabit and Ten-Gigabit interfaces.

Release Notes for the Catalyst 4500E Series Switch, Cisco IOS XE Release 3.4.xSG
OL-27990-04
Limitations and Restrictions
–
Port-channel members do not support multiple classification criteria for a QoS policy.
–
CEF is disabled automatically when uRFP is enabled and TCAM is fully utilized.
•When either the RADIUS-server test feature is enabled or RADIUS-server dead-criteria is
configured, and either RADIUS-server deadtime is set to 0 or not configured, the RADIUS-server
status is not properly relayed to AAA.
Workaround: Configure both dead-criteria and deadtime.

CSCtl06706
•If you use the quick option in the issu changeversion command, the following might occur:
–
Links flap for various Layer 3 protocols.
–
A traffic loss of several seconds is observed during the upgrade process.
Workaround: Do not use the quick option with the issu changeversion command. CSCto51562
•While configuring an IPv6 access-list, if you specify hardware statistics as the first statement in
v6 access-list mode (i.e. before issuing any other v6 ACE statement), it will not take effect.
Similarly, your hardware statistics configuration will be missing from the output of the show
running command.
You will not experience this behavior with IPv4 access lists.
Workaround: During IPv6 access-list configuration, configure at least one IPv6 ACE before the
"hardware statistics" statement. CSCuc53234
•Routed packets that are fragmented are not policed if the egress interface is on the VSS Standby
switch. However, if the egress interface is on the VSS Active switch, these packets are policed.
This applies to QoS policing only. QoS marking, shaping and sharing behave as expected.
Workaround: None. CSCub14402
•When an IPv6 FHS policy is applied on a VLAN and an EtherChannel port is part of that VLAN,
packets received by EtherChannel (from neighbors) are not bridged across the local switch.
Workaround: Apply FHS policies on a non EtherChannel port rather than a VLAN. CSCua53148
•During VSS conversion, the switch intended as the Standby device may require up to 9 minutes to
reach an SSO state. The boot up time depends on the configuration and on the number of line cards
in the system.
Workaround: None. CSCua87538
•Dual connectors (like, an SFP+ transceiver inserted into a CVR-X2-SFP10G module) on the
WS-X4606-X2-E line card are not supported as a VSL.
Workaround: Use any X2-pluggable module on its own in the WS-X4606-X2-E line card.
CSCuc70321
•Memory allocation failures can occur if more than 16K IPv6 multicast snooping entries are present.
Workaround: None. CSCuc77376
•When you connect two PoE-capable Catalyst 4648 or 4748 modules with straight-through copper
cabling, the link may flap, and you may observe incorrect PoE status. If the port belongs to an
EtherChannel, it will repeatedly unbundle, then bundle.
Workarounds:
–
Use a crossover cable.

Cisco IOS XE Release 3.4.1SG or higher. CSCub74707
•Auto negotiation cannot be disabled on the Fa1 port. It must be set to auto/auto, or fixed speed with
duplex auto.
•When performing an ISSU upgrade from a release prior to Cisco IOS 15.1(2)SG to release Cisco
IOS 15.1(2)SG or higher, dynamic ACLs are lost after the first switchover.
Workaround: Enter shut then no shut on any port to restart the authentication session and restore
the ACL. CSCul20163
•When performing an ISSU between any releases prior to Cisco IOS 15.1(1)SG or 3.3.0SG to release
Cisco IOS 15.1(1)SG (or 3.3.0SG) or higher, a switch performing multicast routing may persistently
drop traffic after the upgrade completes. You can recover multicast traffic by reloading the chassis.
Alternately, you can remove all multicast configuration prior to ISSU, and add it back when ISSU
completes. CSCuj42672

Caveats
Open Caveats for Cisco IOS XE Release 3.4.4SG
This section lists the open caveats for Cisco IOS XE Release 3.4.4SG:
•When you enable both Cisco TrustSec and RADIUS accounting, a disparity occurs between the
RADIUS client (Cisco switch) and the RADIUS/CTS server in how the authenticator field in the
header is computed for DOT1X/RADIUS accounting messages.
A Cisco IOS AAA client uses the PAC secret to compute the authenticator; Cisco Secure ACS 5.2
uses the shared secret. This behavior causes a mismatch that results in a rejection of the accounting
message, and the client marks the server as unresponsive.
Workaround: None. You must disable 802.1X accounting. CSCts26844
•When more than one Equal Cost Multipath (ECMP) is available on the downstream switch, and
Mediatrace is invoked to provide flow statistics, the dynamic policy does not show statistics for a
flow.
Mediatrace cannot find the correct inbound interface and applies the dynamic policy on a different
interface from the one used for media flow.
Workaround: None. CSCts20229
•When you add a "bfd" suffix to the snmp server host x.x.x.x configuration command, the BFD traps,
ciscoBfdSessUp and ciscoBfdSessDown, are not generated.
Workaround: Do not specify a "bfd" suffix with the snmp-server host x.x.x.x configuration
command. CSCtx51561
•In a multichassis port channel on a VSS system with a very high number of link up and down events
that occur within a second and typically causes an error-disable event, only the ports on the active
switch are error-disabled due to flaps.
Workaround: None. CSCuc36612
•The following (information-only) error message and traceback may occur during MFIB-to-platform
state updates for Bidirectional PIM (*,G/m) entries associated with Bidirectional PIM rendezvous
points:
%SYS-2-NOBLOCK: may_suspend with blocking disabled. -Process= "MFIB_mrib_read", ipl=

:152CC000+2C50D00 :152CC000+2B5901C
These messages are typically observed during SSO, bootup, or when a PIM-enabled interface
undergoes a state transition on a switch containing Bidir PIM state entries.
Workaround: None. CSCud39208
•Configuring an interface as unidirectional with the unidirectional send-only | receive-only
command still allows an interface to send (configured as Send-only Unidirection Ethernet mode) or
receive (configured as Receive-only Unidirection Ethernet mode) packets in a bidirectional mode.
Workaround: None. CSCui10480
•If you enter the show spi-fc 12 command, a crash occurs.
Workaround: Use the show spi-fc all command to dump all SPI channel information. CSCuc81286
•You can attach an input QoS policy to VSL member ports, but you cannot detach it. You only can
configure VSL ports.
46
Release Notes for the Catalyst 4500E Series Switch, Cisco IOS XE Release 3.4.xSG

Caveats
Workaround: Default the VSL member ports and detach the input QoS policy. CSCuc49150
•A device in a guest VLAN that is connected behind a phone capable of 2nd-port-notification
experiences packet loss following a SSO failover. The device experiences an authentication restart
after the first CDP frame arrives from the phone.
Workaround: None. CSCto46018
•After performing an ISSU from Cisco IOS Release 3.2.3 to 3.2.7, multicast packet loss is observed
after both supervisor engines are running IOS Release 3.2.7
Workaround: Do a switchover. CSCuo18934
•On a VSS active switch, devices (i.e., hosts, phones, or workstations) directly connected to ports
Gi1/7/38, Gi1/7/39, Gi1/7/40, Gi1/7/43 on VLAN 34 cannot reach the internet or server.
Workaround: None. CSCun83237
•Occasionally, when netflow sampling is enabled, LACP requires about 60-70 sec until members are
bundled.
Workaround: Disable netflow sampling. CSCtg00542
•Upon adding a new static MAC entry on a Catalyst 4500X VSS running version 3.4.3 and 3.5.x, the
switch number is truncated in the running config. Although the entry functions as expected, it
displays incorrectly. Upon reload, it encounters an error because the entry is no longer a valid
switch, module, or port.
4500x_vss(config)#mac address-table static 03bf.ac10.0cb9 vlan 1 interface Te1/2/3
4500x_vss#show run | i mac add

Upon reload, the config errors out
mac address-table static 03bf.ac10.0cb9 vlan 1 interface Te2/3
^
% Invalid input detected at '^' marker.
Workaround: After a reload, manually re-add the static entry into the running config. CSCuo60703
•A switch may crash due to an interaction with PIM.
The exact triggers are unknown.
Workaround: None. CSCuo37416
•When ip igmp mroute-proxy is configured and you reload the switch, it will remove the command:
interface Vlan14
ip address 10.1.1.1 255.255.255.252
ip pim sparse-mode
ip igmp mroute-proxy Vlan2137
end
48 Gigabit Ethernet interfaces
2 Ten Gigabit Ethernet interfaces
511K bytes of non-volatile configuration memory.
ip igmp mroute-proxy Vlan2137
^
% Invalid input detected at '^' marker.
Workaround: Reapply the configuration when the switch reboots. CSCum71764

Caveats
Resolved Caveats for Cisco IOS XE Release 3.4.4SG
This section lists the resolved caveats for Cisco IOS XE Release 3.4.4SG:
•When you configure open authentication and perform SSO, the spanning tree state and MAC address
are not synchronized to the new Standby supervisor engine. This behavior interrupts traffic only
after the second switchover because the new Standby supervisor engine possesses the wrong state
after the initial switchover and the second switchover starts the port in the blocking state.
Workaround: Enter shut and no shut on the port to synchronize the STP state. CSCtf52437
•Packets that are routed on the same Layer 3 interface (or SVI) that entered on are dropped if received
on the VSS standby switch.
Workaround: None. CSCuj67614
•A switch crashes on receiving a malformed LLDP packet.
LLDP should be enabled.
Workaround: None. CSCun66735
•Upon removing the active supervisor engine from a switch, multicast and unicast packet loss occur
(for 60 seconds) until route convergence completes.
Workaround: None. CSCun97605
Open Caveats for Cisco IOS XE Release 3.4.3SG
This section lists the open caveats for Cisco IOS XE Release 3.4.3SG:
•When an SNMP query includes the cpmCPUProcessHistoryTable, the query time is very slow, and
CPU utilization of the os_info_p process (OS Information provider) increases substantially. The
query time of an almost fully populated table is 68 minutes.
Workaround: None. CSCth42248
•The show ipv6 access-list command displays incorrect match counts when multicast traffic is
matched to an IPv6 access list that is attached to an SVI.
Workaround: None. CSCth65129
•When you configure open authentication and perform SSO, the spanning tree state and MAC address
are not synchronized to the new Standby supervisor engine. This behavior interrupts traffic only
after the second switchover because the new Standby supervisor engine possesses the wrong state
after the initial switchover and the second switchover starts the port in the blocking state.
Workaround: Enter shut and no shut on the port to synchronize the STP state. CSCtf52437
•If you reboot a switch, the configured value of the interface MTU size for the elements of the port
channel interface does not work for IPv6 traffic.
Workaround: After the switch reloads, enter shut and no shut on the port-channel interface.
CSCto27085
•Dynamic buffer limiting might not function at queue limits less than or equal to 128.
Workaround: Increase the queue limit to at least 256. CSCto57602
•A device in a guest VLAN that is connected behind a phone capable of 2nd-port-notification
experiences packet loss following a SSO failover. The device experiences an authentication restart
after the first CDP frame arrives from the phone.

•If you perform an OIR on a line card, several %C4K_RKNOVA-4-INVALIDTOKENEXPIRED
messages appear in the logs.
Workaround: None. CSCtu37959
•When you enable both Cisco TrustSec and RADIUS accounting, a disparity occurs between the
RADIUS client (Cisco switch) and the RADIUS/CTS server in how the authenticator field in the
header is computed for DOT1X/RADIUS accounting messages.
A Cisco IOS AAA client uses the PAC secret to compute the authenticator; Cisco Secure ACS 5.2

message, and the client marks the server as unresponsive.
Workaround: None. You must disable 802.1X accounting. CSCts26844
•When more than one Equal Cost Multipath (ECMP) is available on the downstream switch, and
Mediatrace is invoked to provide flow statistics, the dynamic policy does not show statistics for a
flow.
Mediatrace cannot find the correct inbound interface and applies the dynamic policy on a different
interface from the one used for media flow.
Workaround: None. CSCts20229
•When a switchover is created on the Mediatrace responder, the dynamic access list created for a
monitored flow tuple is not deleted. Although the Mediatrace initiator creates another set of dynamic
access lists after the switchover, the old ones remain in the configuration.
Stale dynamic access lists force the system to monitor unwanted traffic.
Workarounds:
–
If the switchover is scheduled, remove the scheduled session on the initiator and reschedule the
session after the new active supervisor engine boots on the responder.
–
If the Mediatrace responder SSO is not planned, after the new active supervisor engine boots,
manually delete the stale dynamic access lists. CSCty75070
•When you add a "bfd" suffix to the snmp server host x.x.x.x configuration command, the BFD traps,
ciscoBfdSessUp and ciscoBfdSessDown, are not generated.
Workaround: Do not specify a "bfd" suffix with the snmp-server host x.x.x.x configuration
command. CSCtx51561
•During either a system- or user-initiated reload operation, the following message is observed when
the system shuts down:
HARDWARE WATCHDOG
This message is not observed during a system bootup.
Workaround: None required. This message is information only. CSCtz15738
•In a multichassis port channel on a VSS system with a very high number of link up and down events
that occur within a second and typically causes an error-disable event, only the ports on the active
switch are error-disabled due to flaps.
Workaround: None. CSCuc36612
•If you enter the show spi-fc 12 command, a crash occurs.
Workaround: Use the show spi-fc all command to dump all SPI channel information. CSCuc81286
•When you enter the ip pim register-rate-limit command, the following error message displays:
49

Workaround: None. The ip pim register-rate-limit command does not function. CSCub32679
•Packets that are routed on the same Layer 3 interface (or SVI) that entered on are dropped if received
on the VSS standby switch.
Workaround: None. CSCuj67614
•Ports occasionally stay down after an OIR of a standby line card in VSS.
Workaround: Enter shut, then no shut to bring up the links. CSCuc37676
•You can attach an input QoS policy to VSL member ports, but you cannot detach it. You only can
configure VSL ports.
Workaround: Default the VSL member ports and detach the input QoS policy. CSCuc49150
•When VSS receives a VTP message with information about the creation of 4000 VLANs, traceback
and syslog messages (containing EM-4-SEARCH) are displayed.
Workaround: None. You might try reducing the number of VLANs created at one time.
CSCuc66206
•For packets with the same ingress and egress Layer 3 interface, ingress QoS marking policy does
not work.
Workaround: Turn off ICMP redirect through the ip redirect command. CSCua71929
•When the Wireshark feature is applied on a control panel, it fails to capture the correct packets as
they travel to the CPU in VSS, under the following conditions:
–
Incoming packets on the VSS standby port are directed to the CPU for host learning.
–
Layer 3 exceptions occur for packets arriving on the VSS standby port.
–
ACL logging occurs on the VSS standby port.
Workaround: None. CSCub33727
•The POST results on the VSS standby switch displayed by the show diagnostic result module all
detail command indicate module number 1 rather than 11. The module number is not interpreted by
Cisco IOS.
Workaround: None. CSCuc73632
•The following (information-only) error message and traceback may occur during MFIB-to-platform
state updates for Bidirectional PIM (*,G/m) entries associated with Bidirectional PIM rendezvous
points:
%SYS-2-NOBLOCK: may_suspend with blocking disabled. -Process= "MFIB_mrib_read", ipl=

These messages are typically observed during SSO, bootup, or when a PIM-enabled interface
undergoes a state transition on a switch containing Bidir PIM state entries.
Workaround: None. CSCud39208
•Configuring an interface as unidirectional with the unidirectional send-only | receive-only

•On systems performing multicast routing, a brief increase in CPU consumption occurs every few
minutes. In large-scale environments, this CPU increase is more noticeable.
Workaround: None. CSCub44553
•Following a switchover on VSS, CPU may remain high. The show platform cpu packet statistics
command displays high usage due to “SA Miss.”
Workaround: Clear the MAC table. CSCuh50329

Workaround: None. CSCuj71597
•When a device authenticates with dot1x after authenticating with MAB, any policies applied by
MAB remain in place.
Wokarounds:
–
Ensure that the dot1x supplicant always authenticates before MAB.
–
Create MAB policies for dot1x hosts that do not supply a URL redirect. CSCui79988
•On a Catalyst 4500 VSS using IOS Release XE 3.4.0SG to 3.4.2SG, or 3.5.0E, the show platform

Resolved Caveats for Cisco IOS XE Release 3.4.2SG
This section lists the resolved caveats for Cisco IOS XE Release 3.4.2SG:
•A GLC-GE-100FX pluggable may not operate when used in WS-X4624-SFP-E,
WS-X4640-CSFP-E or WS-X4612-SFP-E modules.
Workaround: None CSCui23911
•The switch may reload unexpectedly or become inaccessible when the integrated web server is used,
either through direct web access to the switch, or indirectly through the webauth feature.
Workaround: Enter either the no ip http server or the no ip http secure-server command. This
disables the http/s server. CSCui14525
Open Caveats for Cisco IOS XE Release 3.4.1SG
This section lists the open caveats for Cisco IOS XE Release 3.4.1SG:
•When an SNMP query includes the cpmCPUProcessHistoryTable, the query time is very slow, and
CPU utilization of the os_info_p process (OS Information provider) increases substantially. The
query time of an almost fully populated table is 68 minutes.
Workaround: None. CSCth42248
•The show ipv6 access-list command displays incorrect match counts when multicast traffic is
matched to an IPv6 access list that is attached to an SVI.
Workaround: None. CSCth65129
•When you configure open authentication and perform SSO, the spanning tree state and MAC address
are not synchronized to the new Standby supervisor engine. This behavior interrupts traffic only
after the second switchover because the new Standby supervisor engine possesses the wrong state
after the initial switchover and the second switchover starts the port in the blocking state.
Workaround: Enter shut and no shut on the port to synchronize the STP state. CSCtf52437
•If you reboot a switch, the configured value of the interface MTU size for the elements of the port
channel interface does not work for IPv6 traffic.
Workaround: After the switch reloads, enter shut and no shut on the port-channel interface.
CSCto27085
•Dynamic buffer limiting might not function at queue limits less than or equal to 128.
Workaround: Increase the queue limit to at least 256. CSCto57602
•A device in a guest VLAN that is connected behind a phone capable of 2nd-port-notification
experiences packet loss following a SSO failover. The device experiences an authentication restart
after the first CDP frame arrives from the phone.

Release Notes for the Catalyst 4500E Series Switch, Cisco IOS XE Release 3.4.xSG
OL-27990-04
Caveats
A Cisco IOS AAA client uses the PAC secret to compute the authenticator; Cisco Secure ACS 5.2
uses the shared secret. This behavior causes a mismatch that results in a rejection of the accounting
message, and the client marks the server as unresponsive.
Workaround: None. You must disable 802.1X accounting. CSCts26844
•When more than one Equal Cost Multipath (ECMP) is available on the downstream switch, and
Mediatrace is invoked to provide flow statistics, the dynamic policy does not show statistics for a
flow.
Mediatrace cannot find the correct inbound interface and applies the dynamic policy on a different
interface from the one used for media flow.
Workaround: None. CSCts20229
•When a switchover is created on the Mediatrace responder, the dynamic access list created for a
monitored flow tuple is not deleted. Although the Mediatrace initiator creates another set of dynamic
access lists after the switchover, the old ones remain in the configuration.
Stale dynamic access lists force the system to monitor unwanted traffic.
Workarounds:
–
If the switchover is scheduled, remove the scheduled session on the initiator and reschedule the
session after the new active supervisor engine boots on the responder.
–
If the Mediatrace responder SSO is not planned, after the new active supervisor engine boots,
manually delete the stale dynamic access lists. CSCty75070
•When you add a "bfd" suffix to the snmp server host x.x.x.x configuration command, the BFD traps,

Release Notes for the Catalyst 4500E Series Switch, Cisco IOS XE Release 3.4.xSG
OL-27990-04
Caveats
•VSS allows you to configure the router MAC address that is used by spanning tree to calculate its
bridge ID. When a switchover occurs, this MAC address is retained at the newly active switch.
However, the spanning tree bridge ID changes because it uses the local chassis MAC address,
instead of the configured router MAC address, to calculate the bridge ID.
Workaround: Ensure that the spanning-tree root is configured in the network. This avoids a
topology change. CSCud94151.
•The show inventory command does not display mux buffers information on the local chassis after
a switchover although this information is displayed prior to a switchover.
Workaround: Enter the show idprom muxbuffer command to display the missing information.
CSCuc79728
•When the VSS active switch is running and the VSS standby switch is booting, ports on the standby
switch boot long before the control plane is fully functional. This may cause channel ports on the
standby switch to start working in independent mode before the channel ports are bundled.
Workaround: Do not configure LACP independent mode. Because the PAgP does not have a
workaround, it may cause a traffic loss of several seconds until the ports are bundled. This situation
occurs only when a switch is booting; it does not apply to a port going down and coming up after
bootup. CSCud94258.
•If REP is configured on a dot1q trunk and the native VLAN is administratively set to something
other then the default, REP packets are not sent on the native VLAN
Workaround: Retain the trunk native VLAN as 1. CSCud05521
•When a session is neither authenticated nor granted fallback authorization (e.g. by entering
guest-vlan or auth-fail-vlan) in multi-auth mode, unauthenticated sessions remain indefinitely and
are not cleared by the system.
Workaround: Clear sessions manually with the clear authentication sessions command.
CSCtg15739
•redirect-url and redirect-acl are not cleared after a successful CoA, causing the final step of Central
Web Authentication to fail.
Workaround: Return a dACL in the authorization profile with successful guest authentication.
CSCue62019
•If URL redirect installed as part of authorization and either of the following occurs, memory will be
leaked:
–
a fast stream of traffic matches the URL redirect ACL as IPDT clears an address,
–
a traffic stream matches the URL redirect ACL and no URL redirect policy is installed for that
IP address,
If this occurs repeatedly, IPDT and other control packet processing ultimately ceases.
Workaround: If this behavior completely fills the CPU buffer, the switch must be reloaded.
However, the frequency of encountering a stuck queue can be reduced to nearly zero by modifying
the URL redirect ACL to permit only 80/443 traffic. CSCug56646
•If a dACL name is too long (about 24 characters, depending on the interface where it is applied), the
ACL will be incorrectly shared over multiple ports.
Workaround: Shorten the dACL name. CSCug78653
•On a switches polled for OIDs under CISCO-PROCESS-MIB and running IOS Release XE 3.3.0SG,
3.3.1SG, 3.3.2SG or 3.4.0SG, the show process memory sorted command displays an increasing
memory usage by the eicored process.

•Whenever a S,G entry expires, a switch shows increasing memory utilization in by the
MFIB_mrib/read/write process.
Workaround: Minimize leak by avoiding S,G deletion events:
–
Extend the receiver-less S,G duration (e.g. ip pim sparse sg-expiry-timer <big value>).
–
If sources are varied, try to minimize them.
–
If some static sources send infrequently, extend the expiry timer to cover the gaps in the packet
stream.
–
If some receivers are unreliable, consider static joins.
S,G clears:
–
Minimize Layer 2 or Layer 3 topology changes that would require multicast reconvergence.
–
Avoid manually clearing mroutes. CSCua62262
•A switch running IOS Release XE 3.4.0SG loses all Layer 3 connectivity to or from the switch IP
address. Switching is unaffected, but routed IP traffic (snmp, ntp, telnet, ssh, etc.) is affected.

Disabling Fa1 prevents the problem. CSCue76243
•A switch running IOS Release 3.3.0SG, 3.3.1SG, 3.3.2SG or 3.4.0SG drops some fragmented

Layer 3 exceptions occur for packets arriving on the VSS standby port.
–
ACL logging occurs on the VSS standby port.
Workaround: None. CSCub33727
•The POST results on the VSS standby switch displayed by the show diagnostic result module all
detail command indicate module number 1 rather than 11. The module number is not interpreted by
Cisco IOS.
Workaround: None. CSCuc73632
•The show inventory command does not display mux buffers information on the local chassis after
a switchover although this information is displayed prior to a switchover.
Workaround: Enter the show idprom muxbuffer command to display the missing information.
CSCuc79728
•The following (information-only) error message and traceback may occur during MFIB-to-platform
state updates for Bidirectional PIM (*,G/m) entries associated with Bidirectional PIM rendezvous
points:
%SYS-2-NOBLOCK: may_suspend with blocking disabled. -Process= "MFIB_mrib_read", ipl=
0, pid= 370
-Traceback= 1#f95b67f80cdf0886bbf15560d7553abc :152CC000+2699F4C :152CC000+269A310

:152CC000+2C50D00 :152CC000+2B5901C
These messages are typically observed during SSO, bootup, or when a PIM-enabled interface
undergoes a state transition on a switch containing Bidir PIM state entries.
Workaround: None. CSCud39208
•When a port connected to a CDP, DHCP, or LLDP speaker goes down, a small memory leak occurs
(typically less than 300 bytes).
Workaround: Disable these protocols on interfaces that might flap frequently. CSCub85948
•VSS allows you to configure the router MAC address that is used by spanning tree to calculate its
bridge ID. When a switchover occurs, this MAC address is retained at the newly active switch.
However, the spanning tree bridge ID changes because it uses the local chassis MAC address,
instead of the configured router MAC address, to calculate the bridge ID.
Workaround: Ensure that the spanning-tree root is configured in the network. This avoids a
topology change. CSCud94151.
•When the VSS active switch is running and the VSS standby switch is booting, ports on the standby
switch boot long before the control plane is fully functional. This may cause channel ports on the
standby switch to start working in independent mode before the channel ports are bundled.

Release Notes for the Catalyst 4500E Series Switch, Cisco IOS XE Release 3.4.xSG
OL-27990-04
Caveats
Workaround: Do not configure LACP independent mode. Because the PAgP does not have a
workaround, it may cause a traffic loss of several seconds until the ports are bundled. This situation
occurs only when a switch is booting; it does not apply to a port going down and coming up after
bootup. CSCud94258.
•When a port connected to a CDP, DHCP, or LLDP speaker goes down, a small memory leak occurs
(typically less than 300 bytes).
Workaround: Disable these protocols on interfaces that might flap frequently. CSCub85948
•When MLD snooping is enabled, control-plane policing on IPv6 ND packets stops working. This
does not impact other control packets.
Workaround: None. CSCua89658
•If REP is configured on a dot1q trunk and the native VLAN is administratively set to something
other then the default, REP packets are not sent on the native VLAN
Workaround: Retain the trunk native VLAN as 1. CSCud05521
•When a session is neither authenticated nor granted fallback authorization (e.g. by entering
guest-vlan or auth-fail-vlan) in multi-auth mode, unauthenticated sessions remain indefinitely and
are not cleared by the system.
Workaround: Clear sessions manually with the clear authentication sessions command.
CSCtg15739
•redirect-url and redirect-acl are not cleared after a successful CoA, causing the final step of Central
Web Authentication to fail.
Workaround: Return a dACL in the authorization profile with successful guest authentication.
CSCue62019
•If URL redirect installed as part of authorization and either of the following occurs, memory will be
leaked:
–
a fast stream of traffic matches the URL redirect ACL as IPDT clears an address,
–
a traffic stream matches the URL redirect ACL and no URL redirect policy is installed for that
IP address,
If this occurs repeatedly, IPDT and other control packet processing ultimately ceases.
Workaround: If this behavior completely fills the CPU buffer, the switch must be reloaded.
However, the frequency of encountering a stuck queue can be reduced to nearly zero by modifying
the URL redirect ACL to permit only 80/443 traffic. CSCug56646
•If a dACL name is too long (about 24 characters, depending on the interface where it is applied), the
ACL will be incorrectly shared over multiple ports.
Workaround: Shorten the dACL name. CSCug78653
•On a switches polled for OIDs under CISCO-PROCESS-MIB and running IOS Release XE 3.3.0SG,
3.3.1SG, 3.3.2SG or 3.4.0SG, the show process memory sorted command displays an increasing
memory usage by the eicored process.
Workaround: Exclude polling of the CISCO-PROCESS-MIB using an SNMP view:
snmp-server view restrict iso included
snmp-server view restrict ciscoProcessMIB excluded
snmp-server community cisco view restrict RO

OL-27990-04
Caveats
•Whenever a S,G entry expires, a switch shows increasing memory utilization in by the
MFIB_mrib/read/write process.
Workaround: Minimize leak by avoiding S,G deletion events:
–
Extend the receiver-less S,G duration (e.g. ip pim sparse sg-expiry-timer <big value>).
–
If sources are varied, try to minimize them.
–
If some static sources send infrequently, extend the expiry timer to cover the gaps in the packet
stream.
–
If some receivers are unreliable, consider static joins.
S,G clears:
–
Minimize Layer 2 or Layer 3 topology changes that would require multicast reconvergence.
–
Avoid manually clearing mroutes. CSCua62262
•A switch running IOS Release XE 3.4.0SG loses all Layer 3 connectivity to or from the switch IP
address. Switching is unaffected, but routed IP traffic (snmp, ntp, telnet, ssh, etc.) is affected.
Workaround: Once the problem occurs, reboot the switch.
Disabling Fa1 prevents the problem. CSCue76243
•A switch running IOS Release 15.1(1)SG, 15.1(1)SG1, 15.1(1)SG2, or 15.1(2)SG, drops some
fragmented packets that are routed through the switch. Bridged traffic is unaffected.
Workaround: None. CSCue96534
•SNMPGET queries for CISCO-PROCESS-MIB fail with the message "No Such Instance currently
exists at this OID."
Workaround: Use SNMPWALK. CSCtz67068
•If a switch issues CLI commands at a high rate (usually by script), it crashes with a message like the
following:
%IOSXE-2-PLATFORM: process ng_dumper: Process eicored: terminated abnormally.
Workaround: Avoid scripted CLI. CSCtz19897
•On Supervisor Engine 7L-E, MAC address learning does not occur on dot1q-tunnel ports.
This behavior is not observed on Supervisor Engine 7-E.
Workaround: None. CSCub01918
•From Cisco IOS Release XE 3.2.0 onwards, configuring an interface as uni-directional with the
unidirectional send-only | receive-only command, still allows the interface to send or receive
packets in a bi-directional mode. An interface that is configured as "Send-only Unidirection
Ethernet mode" receives the packets; an interface configured as "Receive-only Unidirection
Ethernet mode" sends the packets.
Workaround: None. CSCui10480
•A GLC-GE-100FX pluggable may not operate when used in WS-X4624-SFP-E,
WS-X4640-CSFP-E or WS-X4612-SFP-E modules.
Workaround: None CSCui23911
•Following a switchover on VSS, CPU may remain high. The show platform cpu packet statistics
command displays high usage due to “SA Miss.”
Workaround: Clear the MAC table. CSCuh50329
•Frequent polling of CPU-PROCESS-MIB may cause a switch to unexpectedly reload.

Workaround: None.CSCug65204
•SNMP may time out and produce CPUHOG messages when lldpXMedMIB is polled.
Workaround: CSCuh88726
•On a Catalyst 4500 VSS using IOS Release XE 3.4.0SG to 3.4.2SG, or 3.5.0E, the show platform
command may be truncated with a "Timed out" message and may rarely produce an unexpected
reload. The likelihood of a reload increases if the command is issued over an SSH session or if the
output is redirected to a file. The same behavior is observed using IOS Release XE 3.5.0 and the
show tech command.
Workaround: None. CSCul00025
Resolved Caveats for Cisco IOS XE Release 3.4.0SG
This section lists the resolved caveats for Cisco IOS XE Release 3.4.0SG:
•Following an upgrade to IOS Release XE 3.3.1SG, the following error messages might display for
switches with PWR-C45-4200ACV power supplies:
%C4K_CHASSIS-3-INSUFFICIENTPOWERSUPPLIESDETECTED: Insufficient power supplies present
for specified config
%C4K_CHASSIS-3-MIXINVOLTAGEDETECTED: Power supplies in the chassis are receiving
different voltage inputs
%C4K_CHASSIS-3-MIXINPOWERDETECTED: Power supplies in the chassis are of different
types (AC/DC) or wattage
Use the show power command to determine whether 220V inputs are incorrectly detected as “off”
or 110V.
Workaround: Unseat or reseat the impacted power supply and turn on the input power.
CSCuc50555.
•Dynamic ACLs do not function correctly if they have advanced operators, including dscp/ipp/tos,
log/log-input, fragments, and TCP flag operators.
Workaround: Remove these operators from any dynamic ACLs. CSCts05302
•A peer policy is not updated after reauthentication if the policy is changed on the AS beforehand.
After reauthentication, the original peer policy is retained.
Workaround: Enter shut and no shut on the port. CSCts29515
•A switch running a Supervisor Engine 7-E or Supervisor Engine 7L-E fails if you enter show
memory debug leak on the console while show memory detailed process iosd debug leaks is
being executed from another Telnet session.
Workaround: Avoid running both commands simultaneously. CSCty27680
