Configuring Small-Frame Arrival Rate
Incoming VLAN-tagged packets smaller than 67 bytes are considered small frames. They are forwarded by
the switch, but they do not cause the switch storm-control counters to increment.
You globally enable the small-frame arrival feature on the switch and then configure the small-frame threshold
for packets on each interface. Packets smaller than the minimum size and arriving at a specified rate (the
threshold) are dropped since the port is error disabled.
SUMMARY STEPS
1. enable
2. configure terminal
3. errdisable detect cause small-frame
4. errdisable recovery interval interval
5. errdisable recovery cause small-frame
6. interface interface-id
7. small-frame violation-rate pps
8. end
9. show interfaces interface-id
10. show running-config
11. copy running-config startup-config
