Routing Resources
Use the Router Resources page to display TCAM allocation and modify total

device, and IP hosts. Each type generates the following number of TCAM
entries:
- IPv4 static routes—One entry per route
- IP Addresses—Two entries per IP address
- IP Hosts—One entry per host
• Non-IP Entries—TCAM entries reserved for other applications, such as
ACL rules, CoS policers, and VLAN rate limits.
