Port Profiles
When creating a port profile, use the following commands to create the corresponding port groups on
the vCenter Server:
• vmware port-group
• state enabled
Profiles that have the system VLAN configuration allow the VEM to communicate with the VSM.
Make sure that the system port-profile is defined with the right system VLANS.
Use the show port-profile and show port-profile usage commands to collect basic required
information.
Example:
switch(config)# module vem 3 execute vemcmd show port 48
LTL IfIndex Vlan Bndl SG_ID Pinned_SGID Type Admin State CBL Mode Name
17 1a030100 1 T 304 1 32 PHYS UP UP 1 Trunk vmnic1
switch(config)#
Step 3
module vem module_number execute vemcmd set
mtu size ltl port-LTL-number
Example:
switch(config)# module vem 3 execute vemcmd
set mtu 9000 ltl 17
switch(config)#
Designates the MTU size for the port, using the LTL number
obtained in Step 2.
