Enabling ports in a Cisco MDS 9148 or 9148S switch

In Cisco MDS 9148 or 9148S switches, you must manually enable the ports required in a MetroCluster configuration.

  • You can manually enable 16 ports in a Cisco MDS 9148 or 9148S switch.

  • The Cisco switches enable you to apply the POD license on random ports, as opposed to applying them in sequence.

  • Cisco switches require that you use one port from each port group, unless you need more than 12 ports.

  1. View the port groups available in a Cisco switch: show port-resources module blade_number
  2. License and acquire the required port in a port group by entering the following commands in sequence: config t interface port_number shut port-license acquire no shut

    For example, the following command licenses and acquires Port fc 1/45:
    switch# config t
    switch(config)#
    switch(config)# interface fc 1/45
    switch(config-if)#
    switch(config-if)# shut
    switch(config-if)# port-license acquire
    switch(config-if)# no shut
    switch(config-if)# end

  3. Save the configuration: copy running-config startup-config
