Virtual Link Trunking (VLT) in PMUX Mode
VLT allows the physical links between two devices (known as VLT nodes or peers) within a VLT domain to be considered a single logical
link to connected external devices.
For VLT operations, use the following configurations on both the primary and secondary VLT. Ensure the VLTi links are connected and
administratively up. VLTi connects the VLT peers for VLT data exchange.
1 Configure VLTi.
Dell#configure
Dell(conf)#int port-channel 127
Dell(conf-if-po-127)# channel-member fortygige 0/33,37
Dell(conf-if-po-127)# no shutdown
Dell(conf-if-po-127)# end
2 Configure the VLT domain.
Dell#configure
Dell(conf)#vlt domain 1
Dell(conf-vlt-domain)# peer-link port-channel 127
->
VLT peer destination
Dell(conf-vlt-domain)# back-up destination 169.254.31.23
Dell(conf-vlt-domain)#system-mac mac-address
00:01:09:06:06:06
-> unit-id 0 – VLT Primary, unit-id 1 – VLT Secondary
Dell(conf-vlt-domain)# unit-id 0
Dell(conf-vlt-domain)#end
3 Configure the VLT port channel. In the following example, the local and remote VLT port-channels are the same but you can also use
different VLT port-channels.
Dell#configure
Dell(conf)#int port-channel 128
Dell(conf-if-po-128)# portmode hybrid
Dell(conf-if-po-128)# switchport
Dell(conf-if-po-128)# vlt-peer-lag port-channel 128
Dell(conf-if-po-128)# link-bundle-monitor enable
Dell(conf-if-po-128)# no shutdown
Dell(conf-if-po-128)# end
4 Show the VLT peer status.
