• You must congure the interface proxy gateway LLDP to enable or disable a proxy-gateway LLDP TLV on specic interfaces.
• The interface is typically a VLT port-channel that connects to a remote VLT domain.
• The new proxy gateway TLV is carried on the physical links under the port channel only.
• You must have at least one link connection to each unit of the VLT domain.
Following are the prerequisites for Proxy Gateway LLDP conguration:
• You must globally enable LLDP.
• You cannot have interface–level LLDP disable commands on the interfaces congured for proxy gateway and you must enable both
transmission and reception.
• You must connect both units of the remote VLT domain by the port channel member.
• If you connect more than one port to a unit of the remote VLT domain, the connection must be completed by the time you enable the
proxy gateway LLDP.
• You cannot have other conicting congurations (for example, you cannot have a static proxy gateway conguration).
Proxy Gateway LLDP conguration might not operate properly if one of the following conditions is true:
• Any proxy gateway conguration or LLDP conguration is not working.
• LLDP packets fail to reach the remote VLT domain devices (for example, because the system is down, rebooting, or the port’s physical
link connection is down).
