VSP 4000 - SPB Interface Configuration
4001 & 4002: Same configuration on both switches
4001:1(config)#mlt 1 enable name 9001
4001:1(config)#mlt 1 member 1/45-1/46
4001:1(config)#mlt 1 encapsulation dot1q
4001:1(config)#interface mlt 1
4001:1(config-mlt)#isis
4001:1(config-mlt)#isis spbm 1
4001:1(config-mlt)#isis enable
4001:1(config-mlt)#exit
4001:1(config)#interface gigabitEthernet 1/47
4001:1(config-if)#isis
4001:1(config-if)#isis spbm 1
4001:1(config-if)#isis enable
4001:1(config-if)#exit
4001:1(config)#interface gigabitEthernet 1/45-1/47
4001:1(config-if)#no spanning-tree mstp force-port-state enable
Disabling CIST would also disable all other MST instances.
Are you sure you want to continue (y/n) ? y
4001:1(config-if)#exit
VSP 7000 - SPB Interface Configuration
Rear ports – for this configuration example, we are provisioning only the FI Red (ports 38 & 39) and Black
FI (ports 34, 35, & 36) rear ports. We simply just need to select one of the rear ports and enable SPB as all
ports are using the same LACP LAG. On switches 7001 & 7002, we are also configuring the FI Red ports
as an SMLT IST interface, hence, we will need to disable LACP as an IST interface does not support LACP
– we will perform this step latter in this configuration example. Note if you select all ports,
i.e. 34-39, and enable SPBM, this will work, but, you will simply get an error message stating IS-IS is already
enabled on port 39, 35, and 36 – simply just ignore this error message.
7003 and 7004: Same configuration on both switches
7003(config)#interface ethernet 34,38
7003(config-if)#isis
7003(config-if)#isis spbm 1
7003(config-if)#isis enable
7003(config-if)#spanning-tree mstp learning disable
7001 & 7003: Front Ports – Same configuration on both switches
7001(config)#interface ethernet 3,34
7001(config-if)#isis
7001(config-if)#isis spbm 1
