nodename[,...]

    Includes information about communications with specific nodes,
    which you can use wildcards to specify. Each node name can be
    accompanied by optional qualifiers to specify local and remote
    device names.

    If no local or remote device name is specified, the VC and all
    channels associated with the specified node are included.

    Use the SHOW CHANNEL command to display node names and local and
    remote device names.
