Check to ensure that the LLDP Transmit and Receive are enabled on the interface.
Use the
show lldp interface ethernet 1/4
command.
Example:
switch# show lldp interface ethernet 1/4

If LLDP is disabled, the VFC will not come online.
You can enable LLDP transmit and receive with the
interface ethernet 1/4
command:
switch(config)# interface ethernet 1/4
switch(config-if)# lldp ?
receive Enable LLDP reception on interface
transmit Enable LLDP transmission on interface
•
Check that the peer supports LLDP.
Check if remote peers exist. Check if values exist for a peer's LLDP TLVs.
Use the
show lldp interface ethernet 1/4
command.
Example:
switch# show lldp interface ethernet 1/4
