Configuring an SVI TCAM Region

Beginning Cisco NX-OS Release 9.3(3), you can display Layer 3 statistics on SVI interfaces on Cisco Nexus 3100 Series switches. You can change the size of the SVI ternary content addressable memory (TCAM) regions in the hardware to display the Layer 3 incoming unicast counters on SVI interfaces.

For more information, see the Cisco Nexus 9000 Series NX-OS Interfaces Configuration Guide:
