In-Service Modular Hot-Fixes
In-Service Modular Hot-Fixes are supported on platforms: e
In-Service Modular Hot-Fixes provides a tool whereby you can install a patch while the system is on-line
and running. This feature allows a patch to be added to a running FTOS process to obtain debugging
information or to resolve a software issue in a deployed system.
There is no need to reload or reboot the system when the patch is inserted. The In-Service Modular patch
replaces the existing process code. Once installation is complete, the system executes the patch code as
though it was always there.
Add the patch with the
patch flash://RUNTIME_PATCH_DIR/<patchname> command. Remove a patch and
revert to the original code with the
no patch flash://RUNTIME_PATCH_DIR/<patchname> command.
The patch name includes the FTOS version, the platform, the CPU, and the process it affects
(FTOS-platform-cpu-process-patchversion.rtp). For example, a patch labeled
7.8.1.0-EH-rp2-l2mgr-1.rtp
identifies that this patch applies to FTOS version 7.8.1.0, on the E-Series platform, for RP2, addressing the
layer 2 management process, and this is the first version of this patch.
Use the following to add a patch to the system.
