User Guidelines
Since the IP Source Guard uses the Ternary Content Addressable Memory
(TCAM) resources, there may be situations when IP Source Guard addresses are
inactive because of a lack of TCAM resources.
By default, once every minute the software conducts a search for available space
in the TCAM for the inactive IP Source Guard addresses.
Use the
ip source-guard tcam retries-freq
frequency or to disable automatic retries for TCAM space.
Use the
ip source-guard tcam locate
resources for the inactive IP Source Guard addresses.
