Storm protection
This Software Version includes an enhancement to Quality of Service (QoS)
that allows storm protection.
Storm protection uses QoS mechanisms to classify on traffic likely to cause a
packet storm (broadcast and multicast). With a per-port storm protection
mechanism, any traffic over the configured limit is discarded. However, with
QoS storm protection, several actions are possible when a storm is detected:
■ You can disable the port physically.
■ You can disable the port logically.
■ You can disable the port for a particular VLAN.
Enhanced mode must be enabled with the set switch enhancedmode
command in the Switching chapter before you can configure storm protection.
When a storm is detected on a port, a message is automatically recorded in the
log, and you can configure an SNMP trap to signal that a port has been
disabled. When a storm is detected on a trunk or port group, the entire trunk or
port group is disabled.
