Usage
FTOS supports a command to enable viewing of the VLAN input/output counters. This
Information
command also applies to SNMP requests. If the command is not enabled, IFM returns zero
values for VLAN output counters.
SNMP counters differ from show interface counters as SNMP counters must maintain history.
At any point, the value of SNMP counters reflect the amount of traffic being carried on the
VLAN.
VLAN output counters may show higher than expected values because source-suppression
drops are counted.
During an RPM failover event, all SNMP counters remain intact. The counters sync over to the
secondary RPM.
