IPv6: Anycast Address IPv6 Anycast Address Support defines a new type of address, known as an "anycast" address that allows a packet to be routed to one of a number of different nodes all responding to the same address.
IPv6: ICMPv6 Internet Control Message Protocol (ICMP) in IPv6 functions the same as ICMP in IPv4 (RFC 792). ICMPv6 generates error messages, such as ICMP destination unreachable messages and informational messages like ICMP echo request and reply messages. Additionally, ICMP packets in IPv6 are used in the IPv6 neighbor discovery process, path MTU discovery, and the Multicast Listener Discovery (MLD) protocol for IPv6.
Enterprise customers are encouraged to migrate to Cisco Catalyst 3750 Series and Catalyst 3560 Series switches, which provide new and enhanced functionality including IEEE 802.3af Power over Ethernet (PoE), higher-density Gigabit Ethernet (GE), and IPv6 routing. The Cisco Catalyst 3750 Series switches feature Cisco
so, NO, it is not supported on 3550 switches but it is supported on 3560 and 3570 switches.
I think what it is trying to say is that the 3550's can switch IPv6 traffic but not route IPv6 traffic. If you have a need for a multilayer switch that does support most IPv6 features go with either the 3560/3750 series switches.
This document gives several answers on frequently asked questions for PFRv3 channel state behavior.

The need was to reach an host inside a LAN through a VPN connection managed by the LAN gateway (Cisco 1921).
The LAN gateway performs NAT and there was a dedicate nat rule for the host i wanted to reach through VPN.
I couldn't connect to the hos...
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
