Step Command Remarks
5.
Set the number of LLDP
frames sent each time fast
LLDP frame transmission is
triggered.
lldp fast-count count
The default setting is 4.
6.
Set the fast LLDP frame
transmission interval.
lldp timer fast-interval interval
The default setting is 1 second.
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:
Step Command Remarks
1.
Enter system view.

2.
Enter Layer 2/Layer 3
Ethernet interface view,
management Ethernet
interface view, or Layer
2/Layer 3 aggregate
interface view.

Set the encapsulation
format for LLDP frames to
SNAP.

Disabling LLDP PVID inconsistency check
By default, when the system receives an LLDP packet, it compares the PVID value contained in
packet with the PVID configured on the receiving interface. If the two PVIDs do not match, a log
message will be printed to notify the user.
You can disable PVID inconsistency check if different PVIDs are required on a link.
