CN4093 Application Guide for N/OS 8.3
Follow the steps in this section to configure VLAG in environments where the STP
mode is MSTP and no previous VLAG was configured.
The ISL connecting the VLAG peers is shared by all their VLAGs. The ISL needs to
be configured only once on each VLAG peer. Ensure you have the same region
name, revision and VLAN-to-STG mapping on both VLAG switches.
CN 4093(config)# spanning-tree mode mst
CN 4093(config)# interface port 1-2
CN 4093(config-if)# switchport mode trunk
CN 4093(config-if)# lacp mode active
CN 4093(config-if)# lacp key 200
CN 4093(config-if)# exit
CN 4093(config)# vlag isl adminkey 200

configured instead.
b. ISL ports and VLAG ports must be members of the same VLANs.
environment.
CN 4093(config)# vlag tier-id 10
Make sure you configure the VLAG peer (VLAG Peer 2) using the same ISL
aggregation type (dynamic or static), the same VLAN for vLAG ports and vLAG
ISL ports, and the same STP mode and tier ID used on VLAG Peer 1.
