Does 'clear counters interface' clears brdcast packets count as well?

SivaPrabhala

Level 1

Trying to clear counters on port channel interface. It's clearing unicast packet input output count but not broadcast. is there any other command to clear broadcasts or it clears only certain stats?

Received 135148792 broadcasts (0 IP multicasts)

Also, is there way without taking captures you can tell what is the source (mac or ip) of broadcast?

Thanks,

the broadcast must also clear 

but anyway use below to detect the broadcast source 

access-list 100 permit ip any host 255.255.255.255

debug ip packet detail 100

clear counters interface x/x  (this should clear all counter on the interface)

if that is not clearing, tell what what device mode and what IOS code running ?

post complete show interface gix/x output.

Did cleared couple of times but it's not clearing received broadcast packet count for some reason.

It's Cisco IOS XE Software, Version 17.06.05 and cisco ASR1001-X (1NG)
