Procedure for Configuring VMANs

This section describes the procedure for configuring VMANs. Before configuring VMANs, review Guidelines for Configuring VMANs. To configure a VMAN, complete the following procedure at each switch that needs to support the VMAN:

  1. If you are configuring a SummitStack, or an ExtremeSwitching series switch, enable jumbo frames on the switch.
    Note

    Note

    You must enable jumbo frames before configuring VMANs on these systems.
  2. Create a VMAN using the command:
    create vman vman_name | vman_list vr vr_name
  3. Assign a tag value to the VMAN using the command:.
    configure vman vman_name | vman_list tag tag_id
  4. To configure PNP ports on a PEB or PB, use the following command with the tagged option:
    configure vman vman_name | vman_id add ports [ all | port_list ] {untagged { port-cvid port_cvid} | tagged}
  5. To configure CNP ports on a PEB, use the following command with the untagged option:
    configure vman vman_name add ports [ all | port_list ] {untagged { port-cvid port_cvid} | tagged}
    Note

    Note

    You must configure CNP ports as untagged, so that the S-tag is stripped from the frame on egress. If the port-cvid is configured, any untagged packet received on the port will be double tagged with the configured port CVID and the SVID associated with the VMAN. Packets received with a single CVID on the same port will still have the SVID added as usual. As double tagged packets are received from tagged VMAN ports and forwarded to untagged VMAN ports,the SVID associated with the VMAN is stripped. Additionally, the CVID associated with the configured port CVID is also stripped in the same operation.
  6. To configure CEP ports on a PEB, do the following:
    1. Use the following command to establish a physical port as a CEP and configure CVID mapping and translation:
      configure vman vman_name | vman_id add ports port_list cep [ cvid <cvid or cvid_range> { translate <cvid or cvid_range> } } | port-cvid <port_cvid> ] }
    2. Use the following commands to add or delete CVIDs for a CEP and manage CVID mapping and translation:
      configure vman vman_name | vman_id ports port_list add cvid {cvid | cvid_range} {translate cvid | cvid_range }
      configure vman vman_name ports port_list delete
