TCAM Region for IP QoS

By default, there is no space reserved for IP QoS in TCAM. There needs to be a minimum of 512 entries
for the IP QoS region in TCAM, for IP QoS functionality to be enabled.
This size is configurable, but requires a reload to take effect If e nough space is not available in TCAM
after the reload, IP QoS will get disabled automatically.
Tips TCAM space may be allocated for IP QoS using the command:
sdm ipqos number_of_entries.
Verifying the IP QoS Configuration
To verify the IP QoS configuration, use the following commands:
Examples
The following example shows all policy maps configured:
Switch# show policy-map
Policy Map four
