Usage
Information
no default vlan disable is not listed in the running-configuration, but when the
default VLAN is disabled, default-vlan disable is listed in the running-configuration.
enable vlan-counters
Display VLAN counters for ingress and/or egress hardware. You must be in restricted mode to use this command.
E-Series ExaScale
Syntax
enable vlan-output-counters [ingress | egress | all]
To return to the default (disabled), use the no enable vlan-output-counters
command.
Defaults Disabled — VLAN counters are disabled in hardware (all linecards/port-pipes) by default.

Usage
Information
FTOS supports a command to enable viewing of the VLAN input/output counters. This
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.
