Question on VOIP forwarding-class

  • 1.  Question on VOIP forwarding-class

     
    Posted 03-14-2024 09:51

    Hello all.
    I have the following configuration on an EX4300:

    vlans {
        phone {
            vlan-id 201;
        }
    }

    protocols {
        lldp-med {
            interface ge-0/0/7;
        }
    }

    switch-options {
        voip {
            interface ge-0/0/7.0 {
                vlan phone;
                forwarding-class voice;
            }
        }
    }


    What does the "forwarding-class voice" configuration do? 
    1.    Does it populate ge-0/0/7's LLDP-MED message with a TLV telling the connected voip phone to use the codepoints that the switch maps to the forwarding class 'voice'?
    2.    Does it override the ge-0/0/7.0 ieee8021p classifier, and map all frames coming in with the phone vlan-id to forwarding class voice?


    Thanks,
    Deepak
