Configuring MC-LAG
Configuring the Chassis-ID
To configure MC-LAG, a globally unique chassis identifier must first be assigned to each of the switches
that will form the multi-chassis domain. The chassis ID is used to generate globally unique values for the
module identifiers as well as allowing inter-chassis communication.
To configure an OmniSwitch 10K for MC-LAG and assign a globally unique chassis identifier, enter the
multi-chassis chassis-id
-> multi-chassis chassis-id 1
By default, the MC-LAG hello interval and IPC VLAN are set to the values listed in
Aggregation Default Values" on page 8-4
VLAN" on page 8-24
Configuring the IPC-VLAN
Under normal circumstances, it is not necessary to change the IPC VLAN listed in the Default Value table
at the beginning of the chapter.
However, it is important to note that the VLAN configured as the IPC-VLAN is reserved specifically for
MC-LAG purposes and can no longer be used for normal data traffic.
If necessary, use the
-> multi-chassis ipc-vlan 4093
Configuring the Hello-Interval
Hello packets are used for establishing and maintaining the neighbor relationship between multi-chassis
peers and ensures that communication between peers is bi-directional. Hello packets are sent periodically
out VFL interfaces. Bidirectional communication is indicated when the switch sees itself listed in the
neighbor's Hello Packet.
To configure the hello interval between the multi-chassis peers, use the
command as shown below:
-> multi-chassis hello-interval 1
Configuring Aggregate Identifier Ranges
The aggregate identifier ranges are the valid ranges defined for standard aggregates as well as the MC-
LAG link aggregates. Although the default values will typically suffice these values can be modified to
change the maximum number of allowed aggregates using the
-> linkagg range local 0-9 peer 10-19 multi-chassis 20-127
The example above modifies the ranges to allow for 10 local, 10 peer, and 108 MC-LAG link aggregates.
To configure only MC-LAG aggregate identifiers see the example below:
-> linkagg range local none peer none multi-chassis 0-127
