Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
2. Do issu loadversion command, which causes Standby to go down and come up as Standby
(Cisco IOS Release 12.2(31)SB*). The new Standby will crash once and then come up in RPR
mode.
3. Do issu runversion command to make Standby as Active (Cisco IOS Release 12.2(31)SB*).
4. Do issu commitversion command and Standby will come up in Cisco IOS Release
12.2(31)SB*.
The force-rpr 1 command is removed from the configuration by now, since Cisco IOS
Release 12.2(31)SB* image does not support this command.
