Checking the VEM Configuration
You can verify that the ESX host received the VEM configuration and setup.
Step 1 On the ESX host, confirm that the VEM Agent is running and that the correct host uplinks are added to
the DVS.
vem status
Example:
~ # vem status
VEM modules are loaded
Switch Name Num Ports Used Ports Configured Ports MTU Uplinks
vSwitch0 64 3 64 1500 vmnic0
DVS Name Num Ports Used Ports Configured Ports Uplinks
switch 256 9 256 vmnic1 VEM Agent is running
Step 2 Restore connectivity that is lost due to an incorrect MTU value on an uplink.
a. vemcmd show port port-LTL-number
b. vemcmd set mtu value ltl port-LTL-number
Example:
~ # vemcmd show port 48
LTL IfIndex Vlan Bndl SG_ID Pinned_SGID Type Admin State CBL Mode Name
