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.
– Example: snmpset —c public —v2c 10.16.127.10 LLDP-MIB::lldpNotificationInterval.0 I 20
• REST API — Through conguring by REST API method.
Conguring Transmit and Receive Mode
After you enable LLDP, the switch transmits and receives LLDPDUs by default.
To congure the system to transmit or receive only and return to the default, use the following commands.
• Transmit only.
CONFIGURATION mode or INTERFACE mode
mode tx
• Receive only.
CONFIGURATION mode or INTERFACE mode
mode rx
• Return to the default setting.
