A vlan is generating a lot of packets to cpu in show l2stats and increased CPU in 4% . I did;
* PACHAC-EXTRE.27 # clear l2stats vlan v57
* PACHAC-EXTRE.28 # show l2stats v57
Bridge interface on VLAN v57:
Total number of packets to CPU = 1078.
Total number of packets learned = 0.
Total number of IGMP control packets snooped = 0.
Total number of IGMP data packets switched = 0.
Total number of MLD control packets snooped = 0.
Total number of MLD data packets switched = 0.
* PACHAC-EXTRE.29 # show l2stats v57
