Dell EMC VMware Cloud Foundation for PowerEdge MX7000 Deployment Guide

After the VLT is enabled, create the uplink to the network layer above the PowerEdge MX7000 enclosure. The connection should be an Link Aggregation Control Protocol (LACP) active link aggregation of two ports. The MX5108n switches support uplink speeds of 100 GbE, 40 GbE, or 25 GbE on Ethernet port 1/1/11. In this example, the upstream ports are operating at 100 GbE so the breakout mode for the interface is found in the running-configuration and should be:

interface breakout 1/1/11 map 100g-1x

If the running-configuration shows that the port is mapped to 10g or 40g, you can remap it by running the following command:

MX7K-IOM-A2#
                                 MX7K-IOM-A2# configure terminal
                                 MX7K-IOM-A2(config)# interface breakout 1/1/11 map 100g-1x
                                 MX7K-IOM-A2(config)#
                              

A VLT link aggregation is created by creating a VLT port-channel on each of the MX5108n switches. First create the uplink VLT port-channel on both MX5108n switches.

MX7K-IOM-A2(config)#interface port-channel 1
                                 MX7K-IOM-A2(config-if-po-1)# switchport mode trunk
                                 MX7K-IOM-A2(config-if-po-1)# switchport trunk allowed vlan 1611-1614,2711-2712
                                 MX7K-IOM-A2(config-if-po-1)# mtu 9216
                                 MX7K-IOM-A2(config-if-po-1)# vlt-port-channel 1
                                 MX7K-IOM-A2(config-if-po-1)# description VLT-uplink
                                 MX7K-IOM-A2(config-if-po-1)# exit
                              

Now add port 'ethernet 1/1/11' into port-channel 1.

MX7K-IOM-A2(config)#
                                 MX7K-IOM-A2# configure terminal
                                 MX7K-IOM-A2(config)# interface ethernet 1/1/11
                                 MX7K-IOM-A2(config-if-eth1/1/11)# no shutdown
                                 MX7K-IOM-A2(config-if-eth1/1/11)# no switchport
                                 MX7K-IOM-A2(config-if-eth1/1/11)# mtu 9216
                                 MX7K-IOM-A2(config-if-eth1/1/11)# channel-group 1 mode active
                                 MX7K-IOM-A2(config-if-eth1/1/11)# exit
                                 MX7K-IOM-A2(config)#
