To enable local device information to be updated on neighboring devices before being aged out, make
sure the interval to send LLDPDUs is shorter than the TTL of the local device information.

Configuring the Encapsulation Format for LLDPDUs
LLDPDUs can be encapsulated in Ethernet II or SNAP frames.
z With Ethernet II encapsulation configured, an LLDP port sends LLDPDUs in Ethernet II frames and
processes only Ethernet II encapsulated incoming LLDPDUs.
z With SNAP encapsulation configured, an LLDP port sends LLDPDUs in SNAP frames and
processes only SNAP encapsulated incoming LLDPDUs.
By default, LLDPDUs are encapsulated in Ethernet II frames. If the neighbor devices encapsulate
LLDPDUs in SNAP frames, you can configure the encapsulation format for LLDPDUs as SNAP, thus
guaranteeing communication with the other devices in the network.
Follow these steps to configure the encapsulation format for LLDPDUs:
