Configuring the Switch

  Switch Installation and Setup

The following example tells the slave TSM/CPU to use the master TSM/CPU’s backup file as its configuration file. 
The master TSM/CPU’s backup file is 

, and it’s located in the 

 directory:

Smart6500 # set redundancyinfo

HostIP()                                  : 206.61.237.40          

< IP address of the TFTP server

PathFileName()                            : /tftpboot/backup.ztr   

< full path and file name of master’s backup file

Updating Slave redundancy config. Please wait...

Using the master TSM/CPU’s backup file as the slave’s configuration file assures that if the slave assumes the role of 
master, it will be configured identical to the previous master (ELANs, PVCs, PVPs, port settings, and so on). You can, 
however, instruct the slave TSM/CPU to use a file other than the master’s backup file as its configuration file. 

Remember that the slave TSM/CPU’s configuration file must already exist and 
reside within the 

 directory of the TFTP server.

Keep in mind that the 

 command updates only the master’s backup file. If the slave TSM/CPU is set to 

use a configuration file other than the master TSM/CPU’s backup file, the 

 command does not update 

the slave’s configuration file with the master’s current configuration. 

If the slave’s configuration file is not the master’s backup file, use the 

 command 

to sync the slave’s configuration file with the master’s current configuration. For example: 

luxor2 # execute redundancyconfigbackup 

Backup successful

luxor2 #

The slave TSM/CPU’s configuration file now contains the current configuration of the master TSM/CPU.

Redundancy Configuration for CSMs

The SmartSwitch 6500 can use two CSM modules: one active (master), the other in standby (slave). By default, the 
CSM in slot 9 is recognized as the active (master) CSM by the active TSM/CPU module. To set the slave CSM as the 
master CSM perform the following steps:

Access the bootline prompt by rebooting the SmartSwitch 6500, then pressing a key during the start 
up countdown.

At the bootline prompt, enter the 

 command. Mastership is transferred to the redundant CSM. 

Notice that the console becomes inactive.

Transfer both the COM port and Ethernet port cables to the new master CSM module, then press the 
space-bar to regain control of the console.

At the bootline prompt, enter the 

 command to allow the SmartSwitch 6500 to proceed with start 

up.

If the master CSM fails, move the COM port and Ethernet port cables to the slave 
CSM. Remove the failed CSM from the chassis and press the reset button. At start 
up, the master TSM/CPU will automatically discover the slave CSM and use it as 
the new master CSM.
