Configuring TDM UDP CESoP Pseudowire

  1. Configure TDM Port Framing mode.

    On the left E4G-200 Switch:

    configure ports 17 tdm framing mf

    On the Right E4G-400 Switch:

    configure ports 40 tdm framing mf
  2. Create TDM Service Circuit.

    On the left E4G-200 Switch:

    create tdm service circuit "udp-cesop-s2"
    configure tdm service circuit "udp-cesop-s2" add port 17 time-slots 2-4

    On the Right E4G-400 Switch:

    create tdm service circuit "udp-cesop-s2"
    configure tdm service circuit "udp-cesop-s2" add port 40 time-slots 2-4
  3. Configure the loopback vlan.

    On the left E4G-200 Switch:

    create vlan "lpbk"
    enable loopback-mode vlan lpbk
    configure vlan lpbk ipaddress 7.7.7.7 255.255.255.255
    enable ipforwarding vlan lpbk

    On the Right E4G-400 Switch:

    create vlan "lpbk"
    enable loopback-mode vlan lpbk
    configure vlan lpbk ipaddress 2.2.2.2 255.255.255.255
    enable ipforwarding vlan lpbk
  4. Configure the L3 transport vlan to reach the PW peer.

    On the left E4G-200 Switch:

    create vlan "vt1"
    configure vlan vt1 tag 30
    configure vlan vt1 add ports 1 tagged
    configure vlan vt1 ipaddress 40.0.0.1 255.255.255.0
    enable ipforwarding vlan vt1

    On the Right E4G-400 Switch:

    create vlan "vt1"
    configure vlan vt1 tag 20
    configure vlan vt1 add ports 10 tagged
    configure vlan vt1 ipaddress 50.0.0.3 255.255.255.0
    enable ipforwarding vlan vt1
  5. Create CES and add the TDM Service Circuit.

    On the left E4G-200 Switch:

    create ces udp-ces2 psn udp
    configure ces udp-ces2 add service udp-cesop-s2

    On the Right E4G-400 Switch:

    create ces udp-ces2 psn udp
    configure ces udp-ces2 add service udp-cesop-s2
  6. Add Peer to the CES.

    On the left E4G-200 Switch:

    configure ces udp-ces1 add peer ipaddress 2.2.2.2 udp-port local 10001 remote 10001 vlan lpbk

    On the Right E4G-400 Switch:

    configure ces udp-ces1 add peer ipaddress 7.7.7.7 udp-port local 10001 remote 10001 vlan lpbk
    Note

    Note

    A single loopback vlan is sufficient when configuring multiple pseudo-wires to the same peer and each PW is identified using the unique UDP port numbers configured. The recommended option is to use loopback vlan to specify source IP address to be used in TDM UDP PW. However, the user can also use the normal vlan instead of loopback vlan.
