Congure VLT port-channel
A VLT port-channel links an attached device and VLT peer switches, also known as a virtual link trunk.
1 Enter the port-channel ID number on the VLT peer in INTERFACE mode, from 1 to 1024.
interface port-channel id-number
2 Assign the same ID to a VLT port-channel on each VLT peer — peers are seen as a single VLT LAG to downstream devices.
vlt-port-channel vlt-lag-id
3 Repeat the steps on the VLT peer.
Congure VLT LAG — peer 1
OS10(config)# interface port-channel 10
OS10(conf-if-po-10)# vlt-port-channel 1
Congure VLT LAG — peer 2
OS10(config)# interface port-channel 20
OS10(conf-if-po-20)# vlt-port-channel 1
VLT unicast routing
VLT unicast routing enables optimized routing where packets destined for the L3 endpoint of the VLT peer are locally routed. VLT unicast
routing is supported for IPv4 and IPv6.
To enable VLT unicast routing, both VLT peers must be in L3 mode. The VLAN conguration must be symmetrical on both peers. You
cannot congure the same VLAN as L2 on one node and as L3 on the other node.
1 Enter the VLT domain ID in CONFIGURATION mode, from 1 to 1024.
vlt-domain domain-id
2 Enable peer-routing in VLT-DOMAIN mode.

3 Repeat the steps on the VLT peer.
