SmartSwitch 6500 Installation and Setup Guide 3-5
Configuring the Switch Switch Configuration
3.1.3 TSM/CPU Redundancy
The SmartSwitch 6500 is capable of redundant fail-over operation. For your SmartSwitch 6500 to be capable of
redundancy, the SmartSwitch 6500 chassis must contain two TSM/CPU modules. When two CPUs reside within the
same SmartSwitch 6500 chassis, one CPU assumes mastership and the other becomes the slave (exists in standby
mode). By default, at power-up, the TSM/CPU in slot 7 becomes the master and the TSM/CPU in slot 8 becomes the
slave.
As configuration changes are made to the master TSM/CPU (adding ELANs, creating PVCs, and so on), a background
process copies all configuration changes over to the slave TSM/CPU, keeping the slave configuration in sync with the
master. If the master TSM/CPU goes down, the slave TSM/CPU senses this, performs a reboot of the SmartSwitch
6500 system, and (if the master is still not functioning) assumes mastership; placing the original master TSM/CPU in
standby mode.
TSM/CPU Redundancy Commands
Use the
show redundancystatus
command to view your SmartSwitch 6500’s redundancy capabilities. For example,
the following was performed on a SmartSwitch 6500 with redundant TSM/CPUs and redundant CSMs:
Smart6500 # show redundancystatus
Admin Status : Redundancy Enabled
Oper Status : System Is Redundant
Active CPU : Present In Slot #7
Standby CPU : Present In Slot #8
Active CSM : Present In Slot #9
Standby CSM : Present In Slot #10
Smart6500 #
Use the
set redundancyon
and
set redundancyoff
commands to toggle TSM/CPU redundancy and automatic
fail-over on or off.
Use the
execute cpuswitchover
command to manually switch mastership to the redundant TSM/CPU module. Keep
in mind that switching over to the redundant TSM/CPU automatically reboots the SmartSwitch 6500. For example:
Smart6500 # execute cpuswitchover
BackupConfig(N) :
— In this example, did not backup the CPU before switching over
Switching CPU mastership
/
— CPU switch over reboots of the system
3.1.4 CSM Redundancy
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 master CSM by the master TSM/CPU module.
If the master CSM fails, move the COM port and Ethernet port cables to the slave CSM. Remove the failed CSM from
the SmartSwitch 6500 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.
