Support for up to 36 PEs.

o

uRPF on PE ports—Unicast Reverse Path Forwarding (uRPF) checks are supported in
PE units.

FastIron 08.0.50 for Brocade ICX Switches Release Notes Version 1

8

o

Zero touch SPX deployment—Once the Control Bridge is provisioned, this feature
discovers new PE units running in router mode, assigns them IDs, defines SPX ports
or LAGs, and reloads them as PE units.

•

In-Service Software Upgrade (ISSU) for stacking—With ISSU, the stack upgrade occurs in a
particular sequence (one switch at a time), aimed at reducing the disruption of the customer
network connected to the stack.

•

Security enhancements:
o

Sequence numbering in ACLs—You can edit the ACLs using sequence numbers
without having to un-configure and re-configure all the ACL filters.

o

Egress ACL logging support—On both the Brocade ICX 7250 and ICX 7450 series, ACL
logging is now supported for egress ACLs.

o

Interim RADIUS accounting updates for 802.1x authentication and MAC
authentication—Apart from setting the device to send the Accounting Start and
Accounting Stop messages, you can configure the device to send interim updates of
accounting messages to the RADIUS server at regular intervals.

o

RADIUS dead server detection—The RADIUS servers that are unavailable or that
have stopped responding can be detected and marked as dead servers.

o

Classification of RADIUS servers—RADIUS servers can be configured to be used only
for 802.1X authentication, MAC authentication, Web authentication, or a
combination of these authentication methods.

o

Accounting for 802.1x and MAC authentication—Enables the device to log
information on the RADIUS server about 802.1X and MAC authenticated clients.

o

Outbound dynamic IPv4 ACLs and IPv6 ACLs—In addition to inbound dynamic ACL
support, outbound dynamic IPv4 ACLs and IPv6 ACLs are supported.

o

IPv6 ACL support—In addition to dynamic IPv4 ACL support, 802.1X authentication
and MAC authentication implementations support dynamically applying IPv6 ACLs
to a port.

o

o

IPsec—Internet Protocol security (IPsec) is supported on the Brocade ICX 7450
platform to provide secure communication between devices at the network layer
(Layer 3) across public and private networks.

o

PBR support on interface in a VRF—Policy-based routing can be applied on
interfaces that belong to VRFs. PBR can also be used to map IP traffic into a GRE
tunnel or IPsec tunnel, wherein the VRF of the tunnel interface is considered as the
VRF of the next hop.

in multiple primary or secondary PVLANs. Dual mode support is also added for PVLANs. The
PVLANs must be of the same type (primary, isolated, community) on each port. Each PVLAN
on a port belongs to a different PVLAN domain.

•

OOB interface enhancements—The out-of-band (OOB) management port is now a member
of the management VLAN and can be configured to be a member of the management VRF,
with additional options.

PoE firmware files
The following tables lists the PoE firmware file types supported in all 08.0.50 releases. The
firmware files are specific to their devices and are not interchangeable. For example, you cannot
load ICX 7250 firmware on an ICX 7450 device.
Note: The PoE circuitry includes a microcontroller pre-programmed at the Brocade factory. The
software can be loaded as an external file. The initial release of the microcontroller code is still
current and does not need to be upgraded. The PoE firmware version string will be kept updated
to match the corresponding FastIron software version; however, this is only a cosmetic change,
and the firmware itself remains unchanged. If a new version of the code is released, Brocade will
notify its customers of the needed code upgrade. Finally, in the remote case that a failure occurs
during an upgrade process, the switch would still be functional but without PoE circuitry. If you
encounter such an issue, please contact Brocade Technical Support.
