Setting other LLDP parameters
The Time to Live TLV carried in an LLDPDU determines how long the device information carried in the LLDPDU can be saved on a recipient device.
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:
Step | 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 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. |
