Release Modification
12.2(4)XF1 This command was introduced for the Cisco uBR10012 router.
12.2(11)BC3 The clients, counters, history, and states option were added, and the
default display was enhanced to show the version of Cisco IOS software
that is running on the standby PRE module.
Usage Guidelines The show redundancy command shows whether the PRE A slot or PRE B slot contains the active
(primary) Performance Routing Engine (PRE1) module, the status of the standy (secondary) PRE1
module, and the values for the standby PRE1 module’s boot variables and configuration register. In
Cisco IOS Release 12.2(13)BC1 and later releases, it also shows the version of Cisco IOS software that
is running on the standby PRE module.
Note The show redundancy command always shows the correct location of the active PRE1 module. The
other PRE slot will always be marked as Secondary, even if a standby PRE1 module is not installed.
Examples This section contains examples of typical displays for each of the options that are available for the show
redundancy command.
Default Displays
The following example shows a typical display from the show redundancy command. The active PRE1
module is in PRE slot A, and the standby PRE1 module is in PRE slot B:
