VLAG Configuration - VLANs Mapped to MSTI

Configuring the ISL
1. Configure STP:
2. Configure the ISL ports and place them into a portchannel (dynamic or static):
3. Configure the VLAG Tier ID. This is used to identify the VLAG switch in a
4. Configure the ISL for the VLAG peer.

G8264CS Application Guide for ENOS 8.4
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.
RS 8264CS(config)# spanning-tree mode mst
RS 8264CS(config)# interface port 1-2
RS 8264CS(config-if)# switchport mode trunk
RS 8264CS(config-if)# lacp mode active
RS 8264CS(config-if)# lacp key 200
RS 8264CS(config-if)# exit
RS 8264CS(config)# vlag isl adminkey 200
Notes:
 In this case, a dynamic LAG is shown. A static LAG (portchannel) could be
configured instead.
 ISL ports and VLAG ports must be members of the same VLANs.
multi‐tier environment.
RS 8264CS(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 and VLAG ISL
ports, and the same STP mode and tier ID used on VLAG Peer 1.
