VSP 7000 – Rear Port Mode
2.3.1
In the 10.2 release, the VSP 7000 can be configured in Fabric Interconnect Mesh (FI) mode by setting the
rear-port mode to SPB. This allows the VSP 7000 to run SPB via the rear ports using stacking cables to
connect to other VSP 7000s. In the 10.2.1 release, SMLT will be supported allowing for either SPB or
SMLT to operate via the rear port. In the 10.3 release, both SPB and SMLT will be supported via the rear
ports.
Please refer to the Resilient Data Center Solutions Technical Configuration Guide publication number
NN48500-645 for more details.

VSP 7000 – Rear Port Mode LACP Provisioning
2.3.2
By default when rear port mode is enabled, LACP is automatically enabled across all rear ports using a
default LACP key of 4095. If you wish, you can change this value on one or more of the four rear ports. In
SPB rear port mode, the port numbers for each rear port is as follows:

FI Up (right) Top: Ports 34, 35, 36

FI Down (left) Top: Ports 38, 39 (SPB) or ports 38, 39, 40 (Standard)

FI Up (right) Bottom: Port 33

FI Down (left) Bottom: Port 37
For example, to change the LACP on the FI Up (right) Top ports:
interface fastEthernet 34-36
lacp key 4094

show lacp aggr
show lacp port aggr <aggr id>
