The Command Line Interface (CLI)
8.3 Initial Setup— Logging in for the First Time
Logging in for the first time must be done through the serial port console to properly configure the
Ethernet settings and IP addresses for the network.
The username for the CMM is root. The default password is cmmrootpass.
At the login prompt, enter the username: root
When prompted for the password, enter: cmmrootpass
The root password can be changed using the passwd command. For information on resetting the
CMM password back to default, refer to Section 9, “Resetting the Password” on page 99.
8.3.1 Setting IP Address Properties
Note: Changing any of the IP address settings and restarting the network could result in a failover
occurring based on the rules governing redundancy specified in Section 3, “Redundancy,
Synchronization, and Failover” on page 21.
By default, the CMM assigns IP addresses statically:
• eth0, labeled “Ethernet A” on the front panel, is configured with the static IP address
10.90.90.91
• eth1, labeled “Ethernet B” on the front panel, is configured with a static IP address of
192.168.100.92
• eth1:1, an alias of eth1 is used to always point to and be active on the active CMM, is
configured with a static IP address of 192.168.100.93
On initial power-up of a chassis with two CMMs, both CMMs will have the same IP addresses
assigned by default. When the chassis is powered up, the standby CMM automatically decrements
its IP address by one less than the active CMM if it detects a conflict.
Example:
1. A dual CMM Chassis is powered up.
2. Active CMM assigns IP address of 192.168.100.92 to eth1 on the active CMM.
3. Standby CMM assigns IP address of 192.168.100.91 to eth1 on the standby CMM.
At this point the static IP addresses must be changed to appropriate values for their network
configuration, and ensure that the two CMMs do not contain duplicate IP addresses on eth0 and
eth1 to avoid address conflicts on the network.
eth0 and eth1 can also be set using DHCP. eth1:1 will always remain static.When setting both eth0
and eth1 to DHCP, use the /etc/pump.conf to determine which interface should own the default
gateway. The default is for eth0 to own the default gateway. To configure eth1 to own the default
