The first eight rows in the tables (unicast MAC addresses through security ACEs) represent 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. The last row is a
guideline used to calculate hardware resource consumption related to the number of Layer 2 VLANs on
the switch.

Dual IPv4 and IPv6 SDM Templates

You can select SDM templates to support IP Version 6 (IPv6). For more information about IPv6 and how
to configure IPv6 routing, see
This software release does not support IPv6 multicast routing and QoS. This release does support IPv6
Multicast Listener Discovery (MLD) snooping.
This software release does not support Policy-Based Routing (PBR) when forwarding IPv6 traffic. The
software supports IPv4 PBR only when the dual-ipv4-and-ipv6 routing template is configured.
The dual desktop and aggregator IPv4 and IPv6 templates allow the switch to be used in dual stack
environments (supporting both IPv4 and IPv6). Using the dual stack templates results in less TCAM
capacity allowed for each resource. Do not use them if you plan to forward only IPv4 traffic.
These SDM templates support IPv4 and IPv6 environments:

Desktop dual IPv4 and IPv6 default template—supports Layer 2, multicast, routing, QoS, and ACLs
for IPv4; and Layer 2, routing, and ACLs for IPv6 on desktop switches (all Catalyst 3750 switches
except Catalyst 3750-12S).
Desktop dual IPv4 and IPv6 routing template—supports Layer 2, multicast, routing (including
policy-based routing), QoS, and ACLs for IPv4; and Layer 2, routing, and ACLs for IPv6 on desktop
switches (all Catalyst 3750 switches except Catalyst 3750-12S).
Desktop dual IPv4 and IPv6 VLAN template—supports basic Layer 2, multicast, QoS, and ACLs
for IPv4, and basic Layer 2 and ACLs for IPv6 on desktop switches.
