Configuring The Encapsulation Format For Lldpdus - H3C S5120-EI Series Operation Manual

To do...
Set the delay period to send
LLDPDUs
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.
Setting the number of the LLDPDUs to be sent when a new neighboring device is detected
Follow these steps to set the number of the LLDPDUs to be sent when a new neighboring device is
detected
Enter system view
Set the number of the LLDPDUs to be
sent successively when a new
neighboring device is detected

Configuring the Encapsulation Format for LLDPDUs

LLDPDUs can be encapsulated in Ethernet II or SNAP frames.
With Ethernet II encapsulation configured, an LLDP port sends LLDPDUs in Ethernet II frames and
processes only Ethernet II encapsulated incoming LLDPDUs.
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:
