Conguring LLDPDU Intervals
LLDPDUs are transmitted periodically; the default interval is 30 seconds.
To congure LLDPDU intervals, use the following command.
• Congure a non-default transmit interval.

Conguring LLDP Notication Interval
This implementation has been introduced to adhere to the IEEE 802.1AB standard. This implementation allows a user to congure the LLDP
notication interval between 5 (default) and 3600 seconds.
NOTE
:
Before implementation of this feature, notication messages were not throttled. After implementation, the system throttles the lldp
notication messages by 5 seconds (default) or as congured by the user.
lldpNoticationInterval can be congured through three methods:
• CLI — Through the snmp-notification-interval CLI.
– Example: snmp-notification-interval [5–3600]
• SNMP — Through the snmpset command.
