Why SPH013 can not be activated in V800R005C33B118?
As there is an ACL rule is necessary to apply on uplink-board when activating SPH013 patch, furthermore if there are vacant on 0/19 and 0/20 slot. This ACL rule can not be applied successfully, this patch SPH013 can not be activated successfully as well.
MA5600T(config)#patch activate SPH013
Failure: Patch operation in active board failed
Fortunately, we can activate SPH013 by adopting workaround when 0/19 and 0/20 are vacant. The workaround is to “Adding a board offline” no matter whether the uplink-board is vacant or existed.
