Support for IPv6
This chapter lists the IP version 6 (IPv6) features supported on the Catalyst 4500 and Catalyst 4900

The IPv6 for Cisco IOS software feature documentation provides implementation and command
reference information for IPv6 features supported in the Cisco IOS software. Not all IPv6 features are
supported on the Catalyst 4500 and Catalyst 4900 series switches. We strongly recommend that you read
this entire chapter before reading the other IPv6 for Cisco IOS software feature documentation.
This chapter consists of these sections:
• Finding Feature Information, page 63-1
• About IPv6, page 63-1
• IPv6 Default States, page 63-8
Note For Cisco IOS IPv6 Configuration Guides, see:
• IPv6 Configuration Library, Cisco IOS Release 15E

About IPv6
IPv6 provides 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.
