switchxxxxxx(config)# ip source-guard tcam retries-freq 120
13.15 ip source-guard tcam locate
Use the ip source-guard tcam locate Privileged EXEC mode command to manually
retry to locate TCAM resources for inactive IP Source Guard addresses.
Syntax
ip source-guard tcam locate
Parameters
N/A
Command Mode
Privileged EXEC mode
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 60 seconds the software conducts a search for available
space in the TCAM for the inactive IP Source Guard addresses.
Execute the ip source-guard tcam retries-freq command with the never keyword
to disable automatic retries for TCAM space, and then execute this command to
manually retry locating TCAM resources for the inactive IP Source Guard
addresses.
The show ip source-guard inactive EXEC mode command displays the inactive IP
source guard addresses.
Example
The following example manually retries to locate TCAM resources.
switchxxxxxx# ip source-guard tcam locate
