Link Aggregation Configuration Example
11-14 Configuring Link Aggregation
The output algorithm defaults to selecting the output port based upon the destination and source
IP address. This setting will not be changed in our example. In any case, note that the stackable
switch does not support the output algorithm feature.
Configuring the S8 Distribution Switch
The first thing we want to do is set the admin key for all LAGs to the non-default value of 65535 so
that no LAGs will automatically form:
S8(rw)->set lacp aadminkey lag.0.* 65535
LAGs 1 and 2 will form on the S8 so we need to set the admin keys for these LAGs:
S8(rw)->set lacp aadminkey lag.0.1 100
S8(rw)->set lacp aadminkey lag.0.2 200
LACP port state is disabled by default on the S8, so we will enable LACP port state here. We next
want to set the admin keys and port enable LACP for the S8 physical ports:
S8(rw)->set port lacp port ge.1.1 aadminkey 100 enable
S8(rw)->set port lacp port ge.2.1 aadminkey 100 enable
S8(rw)->set port lacp port ge.3.1 aadminkey 100 enable
S8(rw)->set port lacp port ge.4.1 aadminkey 100 enable
S8(rw)->set port lacp port ge.1.2 aadminkey 200 enable
S8(rw)->set port lacp port ge.2.2 aadminkey 200 enable
S8(rw)->set port lacp port ge.3.2 aadminkey 200 enable
S8(rw)->set port lacp port ge.4.2 aadminkey 200 enable
Because we want the two fixed switch stacks to be in charge of port selection, the system priority
for the S8 will be left at the default value of 32768.
Configuring the Fixed Switch Stack 1
The first thing we want to do is set the admin key for all LAGs to the non-default value of 65535 so
that no LAGs will automatically form:
Stack1(rw)->set lacp aadminkey lag.0.* 65535
LAG 1 will form on the fixed switch Stack 1 so we need to set the admin key for this LAG:
Stack1(rw)->set lacp aadminkey lag.0.1 100
LACP port state is disabled by default on the B5s and C5s, so we will enable LACP port state here.
We next want to set the admin keys and port enable LACP for the physical ports:
Stack1(rw)->set port lacp port ge.1.21 aadminkey 100 enable
Stack1(rw)->set port lacp port ge.1.22 aadminkey 100 enable
Stack1(rw)->set port lacp port ge.2.23 aadminkey 100 enable
Stack1(rw)->set port lacp port ge.3.24 aadminkey 100 enable
Next we want to change the system priority for the Stack 1 so that it will be in charge of port
selection on LAG1:
Stack1(rw)->set lacp asyspri 100
Configuring the Fixed Switch Stack 2
The first thing we want to do is set the admin key for all LAGs to the non-default value of 65535 so
that no LAGs will automatically form:
Stack2(rw)->set lacp aadminkey lag.0.* 65535
LAGs 2 and 3 will form on Stack 2 so we need to set the admin key for this LAG:
Stack2(rw)->set lacp aadminkey lag.0.2 200
Stack2(rw)->set lacp aadminkey lag.0.3 300
