Brocade: Configuring IP addresses

The Brocade DCX 8510-8 requires three IP addresses, which are configured using the ipAddrSet command. IP addresses are required for both CP blades (CP0 and CP1) and for the chassis management IP (shown as SWITCH under the ipAddrShowcommand) in the Brocade DCX 8510-8.

NOTE: The default IP addresses and host names for the Brocade DCX 8510-8 are:
– 10.77.77.75 / CP0 (the CP blade in slot 6 at the time of configuration)
– 10.77.77.74 / CP1 (the CP blade in slot 7 at the time of configuration)

ATTENTION! Resetting an IP address while the Brocade DCX 8510-8 has active IP traffic or has management and monitoring tools running, such as DCFM, Fabric Watch, and SNMP, can cause traffic to be interrupted or stopped.

Complete the following steps to set the IP addresses for the Brocade DCX 8510-8.

1.	Log in to the active CP as admin using the serial cable connection.

2.	Set up the Brocade DCX 8510-8 IP address by entering the ipaddrset -chassis command:

swDir:admin> ipAddrSet -chassis

 

Enter the information at the prompts. Specify the -chassis IP address. The -sw 0 IP address is not valid on this chassis.

NOTE: The addresses 10.0.0.0 through 10.0.0.255 are reserved and used internally by the Brocade DCX 8510-8. External IPs must not use these addresses.

3.	Set up the CP0 IP address by entering the ipaddrset -cp 0 command:

swDir:admin> ipAddrSet -cp 0

 

Enter the information at the prompts.

4.	Set up the CP1 IP address by entering the ipaddrset -cp 1 command:

swDir:admin> ipAddrSet -cp 1

 

Enter the information at the prompts.

This is a sample IP configuration:

swDir:admin> ipaddrset -chassis
