Configuring IPv6 Host Functions
This chapter describes how to configure IPv6 host functions on the Catalyst 2960, 2960-S, or 2960-C
switch.
For information about configuring IPv6 Multicast Listener Discovery (MLD) snooping, see Chapter 36,
“Configuring IPv6 MLD Snooping.”
To enable dual stack environments (supporting both IPv4 and IPv6) on a Catalyst 2960 switch, you must
configure the switch to use the a dual IPv4 and IPv6 switch database management (SDM) template. See
the “Dual IPv4 and IPv6 Protocol Stacks” section on page 35-4. This template is not required on Catalyst
2960-S switches.
Note VFor complete syntax and usage information for the commands used in this chapter, see the Cisco IOS
documentation referenced in the procedures.

Understanding IPv6
IPv4 users can move to IPv6 and receive services such as end-to-end security, quality of service (QoS),
and globally unique addresses. The IPv6 address space reduces the need for private addresses and
Network Address Translation (NAT) processing by border routers at network edges.
