Chapter 22 Configuring Quality of Service
Verifying the IP QoS Configuration
Switch(config-if)# service-policy input in-policy
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 enough 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:
