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

Ethernet IP Address [0.0.0.0]: 192.168.1.1

Ethernet Subnetmask [0.0.0.0]: 255.255.255.0

Red Hat Enterprise Solaris vs Linux Run Levels

It's the little things... Why does trying to power off a Linux box using "init 5" fail? Ahhh, RHEL uses different run levels! Gotta keep 'em straight!

Solaris Run Levels:
Run level 0 orderly shut down to "OBP" (OK) prompt
Run level 1 single-user/Administrative mode - user logins disabled
Run level s single-user/Administrative mode - user logins disabled
Run Level S single-user/Administrative mode - user logins disabled
Run level 2 multi-user mode with no NFS
Run level 3 multi-user mode with networking (default)
Run level 4 not used
Run level 5 shut down & power off
Run level 6 full shutdown and reboot (graceful shutdown & reboot)


Linux Run Levels:
Run level 0 orderly shut down and power down
Run level 1 single-user mode
Run level s single-user mode
Run level S single-user mode
Run level 2 multi-user mode with networking support, but no network services(i.e., X-Windows support, NFS/NIS, at, or xinetd support)
Run level 3 multi-user mode with networking support, plus network services
Run level 4 not defined
Run level 5 multi-user mode with X-Windows support (default run level)
Run level 6 full shutdown and reboot (graceful shutdown & reboot)
Run level 7,8,9 not defined

RHEL also has a "poweroff" command that performs the same function as "init 5" on Solaris, or "init 0" on RHEL. However, just remember to put the word "man" in front of that "poweroff" command if you're doing research on it, since the RHEL "poweroff" command works A LOT faster than the Solaris "init 5" command - there's no "quick, kill the process" option to keep the system from going down immediately when you enter "poweroff" in error!!! :-)
