Table 2-10
lists the approximate number of each resource that is supported in each of the IPv4-only
templates for a switch. The values in the template are based on 8 routed interfaces and 1024 VLANs and
represent the approximate hardware boundaries set when a template is selected. If a section of a
hardware resource is full, all processing overflow is sent to the CPU, seriously impacting switch
performance.
Table 2-11
lists the approximate number of each resource supported in each of the dual IPv4-and IPv6
templates for a switch.
