small-frame violation rate

Use the small-frame violation rate pps interface configuration command on the switch stack or on a
standalone switch to configure the rate (threshold) for an interface to be error disabled when it receives
VLAN-tagged packets that are small frames (67 bytes or less) at the specified rate. Use the no form of
this command to return to the default setting.

Usage Guidelines
This command enables the rate (threshold) for a port to be error disabled when it receives small frames.
Small frames are considered packets that are 67 frames or less.
Use the errdisable detect cause small-frame global configuration command to globally enable the
small-frames threshold for each port.
You can configure the port to be automatically re-enabled by using the errdisable recovery cause
small-frame global configuration command. You configure the recovery time by using the errdisable
recovery interval interval global configuration command.
Examples This example shows how to enable the small-frame arrival rate feature so that the port is error disabled
if incoming small frames arrived at 10,000 pps.
Switch(config)# interface gigabitethernet2/0/1
Switch(config-if)# small-frame violation rate 10000
You can verify your setting by entering the privileged EXEC command.
