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.

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.
To configure the VLAG:
VLAG 1 ports. Once the VLAN is ready, the ISL ports are automatically added to it.
RS 8264CS(config)# vlan 100
RS 8264CS(config-vlan)# exit
RS 8264CS(config)# interface port 8
RS 8264CS(config-if)# switchport mode trunk
RS 8264CS(config-if)# switchport trunk allowed vlan 100
RS 8264CS(config-if)# exit
Note: In MSTP mode, VLANs are automatically mapped to CIST.
RS 8264CS(config)# interface port 8
RS 8264CS(config-if)# lacp mode active
RS 8264CS(config-if)# lacp key 1000
RS 8264CS(config-if)# exit
RS 8264CS(config)# vlag adminkey 1000 enable
configuration for VLAG Peer 2.
For each corresponding VLAG on the peer, the port LAG type (dynamic or static),
VLAN, STP mode, and ID must be the same as on VLAG Peer 1.
