System Management Software Configuration Guide for Cisco IE 2000U and Connected Grid Switches
Chapter 6 Configuring SDM Templates
Prerequisites
• 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 the switch.
• 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 the switch
This software release does not support IPv6 multicast routing, IPv6 QoS, or IPv6 Multicast Listener
Discovery (MLD) snooping.
Note An IPv4 route requires only one TCAM entry. Because of the hardware compression scheme used for
IPv6, an IPv6 route can take more than one TCAM entry, reducing the number of entries forwarded in
hardware.
Table 6-2 defines the approximate feature resources allocated by each dual template. Template
estimations are based on a switch with 8 routed interfaces and approximately 1000 VLANs.
Prerequisites
Determine whether routing is enabled on the switch and whether you have both IPv6 and IPv4 traffic on
the network.
