Setting An Encapsulation Format For Lldp Frames - H3C S12500X-AF Series Configuration Manual

By setting the TTL multiplier, you can configure the TTL of locally sent LLDPDUs. The TTL is
expressed by using the following formula:
TTL = Min (65535, (TTL multiplier × LLDP frame transmission interval + 1))
As the expression shows, the TTL can be up to 65535 seconds. TTLs greater than 65535 will be
rounded down to 65535 seconds.
To set LLDP parameters:

Setting an encapsulation format for LLDP frames

LLDP frames can be encapsulated in the following formats:
•
Ethernet II—With Ethernet II encapsulation configured, an LLDP port sends LLDP frames in
Ethernet II frames.
•
SNAP—With SNAP encapsulation configured, an LLDP port sends LLDP frames in SNAP
frames.
Earlier versions of LLDP require the same encapsulation format on both ends to process LLDP
frames. To successfully communicate with a neighboring device running an earlier version of LLDP,
the local device must be set with the same encapsulation format.
To set the encapsulation format for LLDP frames to SNAP:
