Ethernet Switching and Bridging

  • Support for alternate LLDP destination addresses (EX2300, EX2300-C, EX3400, EX4400-24MP, EX4400-24P, EX4400-24T, EX4400-48MP, EX4400-48P, EX4400-48T, EX4600, EX4650, and EX9200)—Starting in Junos OS Release 22.1R1, we support alternate LLDP destination MAC addresses as specified in the IEEE 802.1AB-2016 standard. Our new CLI statements ensure that LLDP packets arrive at the correct destination MAC address. If you don't specify a configuration, then the the device sends the packets to the nearest-bridge MAC address, which is 01:80:c2:00:00:0e. The new CLI statements are:

    • set protocols lldp dest-mac-type <mac-type>—For packets sent out of all interfaces.
    • set protocols lldp interface <intf-name> dest-mac-type <mac-type>—For packets sent out of a specific interface.
