Configuring IPv6 on an Interface Chapter 10 Configuring IPv6 • ssh • telnet • tftp-server • who • write Note Failover does not support IPv6. The ipv6 address command does not support setting standby addresses for failover configurations. The failover interface ip command does not support using IPv6 addresses on the failover and Stateful Failover interfaces. When entering IPv6 addresses in commands that support them, simply enter the IPv6 address using standard IPv6 notation, for example ping fe80::2e0:b6ff:fe01:3b7a. The FWSM correctly recognizes and processes the IPv6 address. However, you must enclose the IPv6 address in square brackets ([ ]) in the following situations: • You need to specify a port number with the address, for example: [fe80::2e0:b6ff:fe01:3b7a]:8080 • The command uses a colon as a separator, such as the write net and config net commands. For example: configure net [fe80::2e0:b6ff:fe01:3b7a]:/tftp/config/pixconfig The following commands were modified to work for IPv6: • debug • fragment • ip verify • mtu • icmp (entered as ipv6 icmp) The following inspection engines support IPv6: • ICMP • TCP • UDP Configuring IPv6 on an Interface At a minimum, each interface needs to be configured with an IPv6 link-local address. Additionally, you can add a site-local and global addresses to an interface. Note FWSM does not support IPv6 anycast addresses. You can configure both IPv6 and IPv4 addresses on an interface. Note You cannot configure IPv6 on an interface that is used by more than one context (a shared VLAN). 10-2 Catalyst 6500 Series Switch and Cisco 7600 Series Router Firewall Services Module Configuration Guide using ASDM OL-20748-01
