Configuring LLDP
The
Link Layer Discovery Protocol
(LLDP) allows network managers to troubleshoot and enhance network
management by discovering and maintaining network topologies over multi-vendor environments. LLDP
discovers network neighbors by standardizing methods for network devices to advertise themselves to other
system, and to store discovered information. Device discovery information includes:
• Device Identification
• Device Capabilities
• Device Configuration
The advertising device transmits multiple advertisement message sets in a single LAN packet. The multiple
advertisement sets are sent in the packet
Type Length Value
(TLV) field. LLDP devices must support chassis and
port ID advertisement, as well as system name, system ID, system description, and system capability
advertisements.
The
LLDP Properties
page contains fields for configuring LLDP.
To open the
LLDP Properties
Page, click

Updates Interval (5-32768) —
Indicates that rate at which LLDP advertisement updates are sent. The
possible field range is 5 - 32768 seconds. The default value is 30 seconds.
Hold Time (2-10) —
Indicates the amount of time that LLDP packets are held before the packets are dis-
carded. The possible field range is 2 - 10 seconds. The field default is 4 seconds.
Reinitializing Delay (1-10) — Indicates the amount of time that passes between disabling LLDP and when
reinitializing begins. The possible field range is 1 - 10 seconds. The field default is 2 seconds.
Transmit Delay (1-8192) — Indicates the amount of time that passes between successive LLDP frame trans-
missions due to changes in the LLDP local systems MIB. The possible field value is
1 – 8192 seconds. The field default is 2 seconds.

Defining SNMP Parameters
Simple Network Management Protocol (SNMP) provides a method for managing network devices. Devices
supporting SNMP run a local software (agent).
The SNMP agents maintain a list of variables, which are used to manage the device. The variables are defined in
the Management Information Base (MIB). The MIB contains the variables controlled by the agent. The SNMP
protocol defines the MIB specification format, as well as the format used to access the information over the
network.
Access rights to the SNMP agents are controlled by access strings. To communicate with the device, the
Embedded Web Server submits a valid community string for authentication. To open the SNMP page, click
System
→
SNMP
in the tree view.
This section contains information for managing the SNMP configuration.
Defining SNMP Global Parameters

Local Engine ID
(10 - 64 Hex Characters)
— Indicates the local device engine ID. The field value is a
hexadecimal string. Each byte in hexadecimal character strings is two hexadecimal digits. Each byte can be
separated by a period or a colon. The Engine ID must be defined before SNMPv3 is enabled.
For stand-alone devices select a default Engine ID that is comprised of Enterprise number and the default MAC
address.
Use Default
— Uses the device generated Engine ID. The default Engine ID is based on the device MAC
address and is defined per standard as:
First 4 octets
— first bit = 1, the rest is IANA Enterprise number.
Fifth octet
— Set to 3 to indicate the MAC address that follows.
Last 6 octets
— MAC address of the device.

Figure 1-31. STP Port Settings
Port
— Port on which STP is enabled.
STP
— Enables or disables STP on the port.
Fast Link
— When selected, enables Fast Link mode for the port. If Fast Link mode is enabled for a port, the
Port State
is automatically placed in the
Forwarding
state
when the port link is up. Fast Link mode optimizes
the time it takes for the STP protocol to converge. STP convergence can take 30-60 seconds in large networks.
Root Guard
—
When checked, prevents devices outside the network core from being assigned the spanning tree
root.
Port State
— The current port STP state. If enabled, the port state determines what forwarding action is taken
on traffic. Possible port states are:
Disabled
— The port link is currently down.
Blocking
— The port is currently blocked and cannot be used to forward traffic or learn MAC addresses.
Blocking is displayed when Classic STP is enabled.
Listening
— The port is currently in the listening mode. The port cannot forward traffic nor can it learn
MAC addresses.
52
www.dell.com | support.dell.com
Learning
— The port is currently in the learning mode. The port cannot forward traffic however it can
learn new MAC addresses.
Forwarding
— The port is currently in the forwarding mode. The port can forward traffic and learn new
MAC addresses.
Speed
— Speed at which the port is operating.
Path Cost (1-200000000)
— The port contribution to the root path cost. The path cost is adjusted to a higher or
lower value, and is used to forward traffic when a path being rerouted.
Default Path Cost
— The default path cost of the port is automatically set by the port speed and the default
path cost method.
The default values for long path costs are:
Ethernet
- 2000000
Fast Ethernet
- 200000
Gigabit Ethernet
- 20000
The default values for short path costs (short path costs are the default) are:
Ethernet
- 100
Fast Ethernet
- 19
Gigabit Ethernet
- 4
Priority (0-240, in steps of 16)
— The priority value of the port. The priority value influences the port choice
when a bridge has two ports connected in a loop. The priority value is between 0-240. The priority value is
provided in increments of 16.
Designated Bridge ID
— The bridge priority and the MAC Address of the designated bridge.
Designated Port ID
— The selected port’s priority and interface.
Designated Cost
— The cost of the port participating in the STP topology. Ports with a lower cost are less likely
to be blocked if STP detects loops.
Forward Transitions
— The number of times the port has changed from the
Blocking
state to the
Forwarding
state.
LAG
— The LAG to which the port is attached.

— The LAG is in the learning mode and cannot forward traffic, but it can learn new MAC
addresses.
Forwarding
— The LAG is currently in the forwarding mode, and it can forward traffic and learn new MAC
addresses.
Broken
— The LAG is currently malfunctioning and cannot be used for forwarding traffic.
Path Cost (1-200000000)
— Amount the LAG contributes to the root path cost. The path cost is adjusted to a
higher or lower value, and is used to forward traffic when a path being rerouted. The path cost has a value of 1 to
200000000. If the path cost method is short, the LAG cost default value is 4. If the path cost method is long, the
LAG cost default value is 20000.
Default Path Cost
— When selected, the LAG path cost returns to its default value.
Priority (0-240, in steps of 16)
— The priority value of the LAG. The priority value influences the LAG choice
when a bridge has two looped ports. The priority value is between 0-240, in increments of 16.
Designated Bridge ID
— The bridge priority and the MAC Address of the designated bridge.
Designated Port
ID
— The port priority and interface number of the designated port.
Designated Cost

Configuring QinQ
This section contains information for configuring Customer VLANs using the Web Interface and using the CLI.
QinQ tagging allows network managers to add an additional tag to previously tagged packets. Customer VLANs
are configured using QinQ. Adding additional tags to the packets helps create more VLAN space. The added tag
provides VLAN ID to each customer, this ensures private and segregated network traffic. The VLAN ID tag is
assigned to a customer port in the service providers network. The designated port then provides additional
services to the packets with the double-tags. This allows administrators to expand service to VLAN users. To
configure customer VLANs:

Configuring Load Balancing
Load Balancing enables the even distribution of data and/or processing packets across available network
resources. For example, load balancing may distribute the incoming packets evenly to all servers, or redirect
the packets to the next available server. Load Balancing is configured on the LAG Configuration page.
NOTE: LAGs can be configured according to the following load balancing types: Layer 2 or Layer 2 and Layer 3 or
Layer2, Layer 3 and Layer 4.
The
LAG Configuration
page contains fields for configuring parameters for configured LAGs. The device
supports up to eight ports per LAG, and eight LAGs per system.
