A hitless upgrade means that a software upgrade does not require a reboot of the line cards. A warm upgrade means that a software upgrade requires a reset of the line cards and SFMs. A warm upgrade is possible for major releases and lower, while a hitless upgrade can only support patch releases. You load the software upgrade on one RPM and then issue this command with the rpm keyword to move the software to the other RPM. The system senses the condition and provides a series of prompts appropriate to that context, as shown in the following example: Note: On C-Series, this command could affect traffic (even during hot-failover) since the switch fabric present on the RPM is taken down during the failover. Example Figure 21-1. redundancy force-failover rpm Command Example FTOS#redundancy force-failover rpm Peer RPM's SW version is different but HA compatible.
