Command Remarks
1. Enter system view.
system-view N/A
2. Set the TTL multiplier.
lldp hold-multiplier value The default setting is 4.
3. Set the LLDP frame transmission
interval.
lldp timer tx-interval interval
The default setting is 30
seconds.
4. Set the token bucket size for
sending LLDP frames.
lldp max-credit credit-value The default setting is 5.
5. Set the LLDP frame transmit
delay.
lldp timer tx-delay delay The default setting is 2 seconds.
6. Set the number of LLDP frames
sent each time fast LLDP frame
transmission is triggered.
lldp fast-count count The default setting is 4.
7. 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 configured with the same encapsulation format.
To set the encapsulation format for LLDP frames to SNAP:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter Layer 2/Layer 3
Ethernet interface view, or
Layer 3 aggregate interface
view.
interface interface-type interface-number N/A
3. Set the encapsulation format
for LLDP frames to SNAP.
• In Layer 2 Ethernet interface view:
lldp encapsulation snap
• In Layer 3 Ethernet interface view:
lldp [ agent { nearest-customer |
nearest-nontpmr } ] encapsulation snap
• In Layer 3 aggregate interface view:
lldp agent { nearest-customer |
nearest-nontpmr } encapsulation snap
By default, Ethernet II
encapsulation format
applies.
Configuring CDP compatibility
Before you configure CDP compatibility, complete the following tasks:
• Globally enable LLDP.
