SHOW SWITCH PORT INTRUSION
Syntax
show switch port= port intrusion
Parameter
port Specifies the port where you want to view the number
of intrusions that have occurred. You can specify
more than one port at a time.
Description
This command displays the number of times a port has detected an
intrusion violation. An intrusion violation varies depending on the security
mode:
ˆ Limited Security Level - An intrusion is an ingress frame with a source
MAC address not already learned by a port after the port had reached
its maximum number of dynamic MAC addresses, or that was not
assigned to the port as a static address.
ˆ Secured Security Level - An intrusion is an ingress frame with a source
MAC address that was not entered as a static address on the port.
ˆ Locked - An intrusion is an ingress frame with a source MAC address
that the port has not already learned or that was not assigned as a
static address.
Example
The following command displays the number of intrusion violations
detected on ports 12 and 21:
set switch port=12,21 intrusion
