If you have network connection issues or until the CMM has a working IP address assigned to it, you must use a serial connection to communicate with the CMM.

After establishing a serial connection to the CMM, you can verify its network settings and/or setup a new network configuration.

You can choose to configure the CMM and server module(s) with static or DHCP IP addresses. The default out-of-box configuration for all CMM network settings is to request DHCP IP address assignment.  The network settings may appear to have garbage settings if the CMM NET_MGT port is not connected to an active network when the CMM is started.

Logging into to a CMM via serial connection

There are 3 possible addresses to be used.

CMM in lower slot (CMM0)

CMM in upper slot (CMM1)

Master CMM – In a 2 CMM configuration there is a failover capability in

the CMMs to provide redundancy. This address will always be used by the

Master CMM in addition to the specific CMM addresses above.

Note the example below shows a serial connection to the Master CMM.

A serial connection to the Standby will not allow examination or set up

of the network parameters. To confirm that the serial connection is to

the active CMM used the "-> show /CMM/redundancy" command and check

the property “status” is set to active.

->

-> show /CMM/redundancy

/CMM/redundancy

Targets:

Properties:

fru_name = /CH/CMM0

initiate_failover_action = (none)

status = Active

1. Type one of the following commands to set the SP working directory:
   
   
   

   For CMM in slot 0: cd /CMM/network/CMM0
   For CMM in slot 1: cd /CMM/network/CMM1
   For master CMM : cd /CMM/network/MASTERCMM
   
   
   

   2) Type the show command to view the IP address(es) assigned, for example:
   
   For a chassis CMM in slot 0: show /CMM/network/CMM0
   For a chassis CMM in slot 1: show /CMM/network/CMM1
   For master CMM : show /CMM/network/MASTERCMM

For all CMM network settings: show -l all /CMM/network

.

EXAMPLE:

-> show /CMM/network/CMM0

 /CMM/network/CMM0
    Targets:

    Properties:
        commitpending = (Cannot show property)
        ipaddress = 10.16.52.149
        ipdiscovery = static
        ipgateway = 10.16.52.1
        ipnetmask = 255.255.252.0
        macaddress = 00:03:BA:C0:FF:EE
        pendingipaddress = 10.16.52.149
        pendingipdiscovery = static
        pendingipgateway = 10.16.52.1
        pendingipnetmask = 255.255.252.0

    Commands:
        cd
        set
        show

->

Type the following commands to change the existing IP address assigned.

-> cd /CMM/network/CMM0

-> set pendingipaddress=static_IP_address  Type this command using the static IP address that you want to assign to the CMM
-> set pendingipnetmask=static_netmask_address Type this command using the static netmask address that you want to assign to the CMM
-> set pendingipgateway=static_netmask_address Type this command using the static gateway address that you want to assign to the CMM
-> set pendingipdiscovery=static Type this command using the value static. Options are static or dhcp
-> set commitpending=true  Type this command to assign the network settings specified
->

Verify the new network settings are correct:

-> show /CMM/network/CMM0

To log out of the CMM, type:

-> exit

Repeat the above example steps to configure the settings for "/CMM/network/CMM1" and "/CMM/network/MASTERCMM".
