The following HSA configuration examples refer to a Cisco 7513. If you have a Cisco 7507, the primary
Note
difference is that the active and the standby RSPs are located in slots 2 and 3, respectively.
Specifying the Default Standby RSP2
Your view of the environment is always from the active RSP2 perspective, you must define a default
standby RSP2. The router uses the default standby information when booting.
•
•
To define the default standby RSP2, use the following commands in
Table 4 Defining the Default Standby RSP
Command
Step 1
Router# configure terminal
Step 2
Router(config)# slave default-slot
processor-slot-number
Step 3
Router(config)# end
Step 4
Router# copy system: running-config nvram:startup-config
Upon the next system reboot, the above changes take effect (if both RSP2 cards are operational). Thus,
the specified default standby becomes the standby RSP2 card. The other RSP2 card takes over control
of the system and controls all functions of the router.
If you do not specifically define the default standby RSP2, the RSP2 card located in the higher number
processor slot is the default standby. On the Cisco 7507, processor slot 3 contains the default standby
RSP. On the Cisco 7513, processor slot 7 contains the default standby RSP.
The following example sets the default standby RSP2 to processor slot 2 on a Cisco 7507:
Router# configure terminal
Router (config)# slave default-slot 2
Ctrl-Z
Router# copy running-config startup-config

If a system boot is due to powering up the router or using the reload command, then the specified
default standby is the standby RSP2.
If a system boot is due to a system crash or hardware failure, then the system ignores the default
standby designation and makes the crashed or faulty RSP2 the standby RSP2.
