IP Source Guard Commands

IP Source Guard is a security feature that filters IP traffic on network interfaces
based on manually configured entries in the IP Source Guard table, or static and
dynamic entries in the DHCP Snooping table when enabled (see "DHCP Snooping
Commands" on page 4-231). IP source guard can be used to prevent traffic attacks
caused when a host tries to use the IP address of a neighbor to access the network.
This section describes commands used to configure IP Source Guard.
Note:
Due to a chip limitation, IP source guard and Quality of Service (only for IP related
QoS function) cannot be enabled at the same time. Thus, if the user has already
enabled the IP source guard function, it needs to be disabled first in order for the
QoS function to work and vice versa.
