Chapter5 Redundancy and SONET APS Configuration
NSP Redundancy
Verifying NSP Redundancy for Hardware Backup
To verify that the NSP redundancy is configured for hardware backup, use the show bootvar and dir
EXEC commands from Step 1 and Step 2. Check that both NSPs use the same system image and store
the image in identical locations.
Using NSP Redundancy for Software Error Protection
For software error protection, the primary and secondary NSPs should have different system images.
Cisco recommends using NSP redundancy for software error protection when you are using new or
experimental Cisco IOS software.
To specify different startup images for the primary and secondary NSPs, complete the following steps,
beginning in EXEC mode:
Step 1 Use the dir {bootflash: | disk0: | disk1: | sec-bootflash: | sec-disk0: | sec-disk1:} EXEC command to
verify the locations and versions of the primary and secondary NSP software images.
Switch# dir disk0:
Directory of disk0:/
3 -rw- 628539 Jan 01 2000 00:08:55 c6400s-wp-mz.120-5.DB
376 -rw- 2134 Jan 05 2000 22:05:27 startup.config
109760827 bytes total (108228293 bytes free)
Switch# dir sec-disk0:
Directory of sec-disk0:/
8 -rw- 628224 Jul 01 1999 00:08:55 c6400s-wp-mz.120-5.DB
184 -rw- 2134 Jan 05 2000 22:05:27 startup.config
109760512 bytes total (108228608 bytes free)
Step 2 If necessary, copy the desired system images to the primary and secondary NSPs. Make sure the primary
and secondary NSPs use different image versions.
Switch# copy tftp://10.1.1.1/c6400s-wp-mz.120-7.DB disk0:c6400s-wp-mz.120-7.DB
Switch# copy tftp://10.1.1.1/c6400s-wp-mz.120-5.DB sec-disk0:c6400s-wp-mz.120-5.DB
Step 3 From global configuration mode, use the boot system global configuration command to boot the images
from the appropriate locations. Enter the image for the primary NSP first.
Switch# configure terminal
Switch(config)# boot system flash disk0:c6400s-wp-mz.120-7.DB
Switch(config)# boot system flash disk0:c6400s-wp-mz.120-5.DB
Step 4 Set the configuration register to load the system image from Flash.
Switch (config)# config-register 0x2101
Step 5 Enable automatic synchronization of the redundant NSPs.
Switch(config)# redundancy
Switch(config-r)# main-cpu
Switch(config-r-mc)# auto-sync standard
Switch(config-r-mc)# end
