Explanation:
To verify a connection between two veth ports on a VEM, follow these steps:
Step 1 On the VSM, enter the show vlan command to view the state of the VLANs associated with the port. If the VLAN associated with a port is not active, then the port may be down. In this case, you must create the VLAN and activate it.
Step 2 To see the state of the port on the VSM, enter a show interface brief command.
Step 3 Enter the module vem module-number execute vemcmd show port command to display the ports that are present on the VEM, their local interface indices, VLAN, type (physical or virtual), CBL state, port mode, and port name.
The key things to look for in the output are:
State of the port.
CBL.
Mode.
Attached device name.
The LTL of the port you are trying to troubleshoot. It will help you identify the interface quickly in other VEM commands where the interface name is not displayed.
Make sure the state of the port is up. If not, verify the configuration of the port on the VSM.
Step 4 To view the VLANs and their port lists on a particular VEM, use the module vem module-number execute vemcmd show bd command: n1000V# module vem 5 execute vemcmd show bd
