Step Command Remarks
2. Set the TTL multiplier. lldp hold-multiplier value The default setting is 4.
3. Set the LLDPDU transmit
interval.
lldp timer tx-interval interval
The default setting is 30
seconds.
4. Set the token bucket size for
sending LLDPDUs.
lldp max-credit credit-value The default setting is 5.
5. Set the LLDPDU transmit delay. lldp timer tx-delay delay The default setting is 2 seconds.
6. Set the number of LLDPDUs
sent each time fast LLDPDU
transmission is triggered.
lldp fast-count count The default setting is 4.
7. Set an interval for fast LLDPDU
transmission.
lldp timer fast-interval interval The default setting is 1 second.
Setting an encapsulation format for LLDPDUs
LLDPDUs can be encapsulated in the following formats: Ethernet II or SNAP frames.
• With Ethernet II encapsulation configured, an LLDP port sends LLDPDUs in Ethernet II frames.
• With SNAP encapsulation configured, an LLDP port sends LLDPDUs in SNAP frames.
To set the encapsulation format for LLDPDUs to SNAP:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter Layer 2 or Layer 3
Ethernet interface view or
Layer 2 aggregate interface
view.
interface interface-type interface-number N/A
3. Set the encapsulation
format for LLDPDUs to
SNAP.
• In Layer 2 or Layer 3 Ethernet interface
view:
lldp [ agent { nearest-customer |
nearest-nontpmr } ] encapsulation snap
• In Layer 2 aggregate interface view:
lldp agent { nearest-customer |
nearest-nontpmr } encapsulation snap
By default, Ethernet II
encapsulation format
applies.
NOTE:
LLDP of earlier versions requires the same encapsulation format on both ends to process LLDPDUs. For this
reason, to communicate stably with a neighboring device running LLDP of earlier versions, the local device
should be configured with the same encapsulation format.
Configuring CDP compatibility
When the switch is directly connected to a Cisco device that supports only CDP rather than LLDP, you can
enable CDP compatibility to enable the switch to exchange information with the directly-connected
device.
