After an incident where a FPC were powered off, it was noticed that some sub interfaces stopped reporting traffic

NAT process is good without any problem, the issue is with the amount of traffic that mams units are showing 0.

mams interfaces are showing 0 traffic, however the service is ok with no impact, this happened after a reboot of the FPC

This could be a cosmetic issue, the customer replaced the FPC without the option to check anything else but it was suggested to reboot the card which could have cleared the issue as well
