Scalability Numbers

MAC, routing, security, and QoS scalability numbers depend on the  type template used in the switch. Routing template is not supported in  the LAN Base feature set. Table 10 shows Cisco Catalyst 3750-X and  3560-X Series Switch scalability numbers.

Two "footnotes".

What Serge has provided is TCAM allocations for IPv4 templates.  If you enable IPv6, resource allocations change.

Some/all(?) TCAM tables can overflow into normal RAM.  I.e. These might not be all hard limits, but when TCAM features do overflow into normal RAM, performance often becomes very, very poor.
