  • 1.  Connection EX2200 to Cisco 2921

    Posted 01-06-2025 11:09

    Hi,

    I have a Cisco 2921 voip router currently interlinked with old Cisco Catalyst switch, and I want to migrate this link to Juniper EX2200.

    Here below is the current router and switch ports config.

    Cisco 2921 part:

    interface GigabitEthernet0/0
     no ip address
     duplex auto
     speed auto
     bridge-group 1

    bridge 1 protocol ieee
    bridge 1 route ip

    On the old Cisco Catalyst is

    interface FastEthernet0/23
     switchport access vlan 10
     switchport mode access
     switchport voice vlan 10
     spanning-tree portfast

    And this configuration WORKS!

    Now, I tried simply replicate config on Juniper. I tried two different versions:

    Simply access with vlan.

        ge-0/0/44 {
            unit 0 {
                family ethernet-switching {
                    port-mode access;
                    vlan {
                        members 10;
                    }
                }
            }
        }

    This is NOT working!

    So I configured another port with voip.

        ge-0/0/45 {
            unit 0 {
                family ethernet-switching {
                    port-mode access;
                    vlan {
                        members 10;
                    }
                }
            }
        }

    and 

    set ethernet-switching-options voip interface ge-0/0/45.0 vlan 10 
    set ethernet-switching-options voip interface ge-0/0/45.0 forwarding-class expedited-forwarding

    This also NOT working!

    Any idea how should I configure the port to be able to work with Cisco 2921 port ?

    Hi

    What about the following?

    --

    set vlans data-vlan vlan-id 77 
    set vlans voice-vlan vlan-id 10 
    set vlans data-vlan interface ge-0/0/44.0
    set interfaces ge-0/0/44 unit 0 family ethernet-switching vlan members data-vlan
    set interfaces ge-0/0/44 unit 0 family ethernet-switching port-mode access
    set ethernet-switching-options voip interface ge-0/0/44.0 vlan voice-vlan
    set ethernet-switching-options voip interface ge-0/0/44.0 forwarding-class assured-forwarding 

    --

    Data traffic is untaged, so I allocate other vlan. 

     
    Please refer to the following.
