Configuring LLDP (Extreme Networks S- K- and 7100-Series)

Step Task Command(s)
1 Configure global system LLDP parameters. set lldp tx-interval

set lldp hold-multiplier

set lldp trap-interval

set lldp med-fast-repeat

clear lldp

2 Enable/disable specific ports to:
  • Transmit and process received LLDPDUs
  • Send LLDP traps
  • Send LLDP-MED traps
set/clear lldp port status

set/clear lldp port trap

set/clear lldp port med-trap

3 Configure an ECS ELIN value for specific ports. set/clear lldp port location-info
4 Configure Network Policy TLVs for specific ports. set/clear lldp port network-policy
5 Configure which optional TLVs should be sent by specific ports. For example, if you configured an ECS ELIN and/or Network Policy TLVs, you must enable those optional TLVs to be transmitted on the specific ports. set/clear lldp tx-tlv

Example LLDP Configuration: Time to Live

This example sets the transmit interval to 20 seconds and the hold multiplier to 5, which will configure a time-to-live of 100 to be used in the TTL field in the LLDPDU header.

System(rw)->set lldp tx-interval 20
System(rw)->set lldp hold-multiplier 5

Example LLDP Configuration: Location Information

On an S- K- and 7100-Series device, after you configure a location information value, you must also configure the port to send the Location Information TLV with the set lldp port tx-tlv command. This example configures the ELIN identifier 5551234567 on ports ge.1.1 through ge.1.6 and then configures the ports to send the Location Information TLV.

System(rw)->set lldp port location-info 5551234567 ge.1.1-6
System(rw)->set lldp port tx-tlv med-loc ge.1.1-6
