Usage Guidelines
To configure the dual IPv4 and IPv6 template, enter the sdm prefer dual-ipv4-and-ipv6 {default | vlan)
global configuration command and reload the switch.
The ipv6 access-list command is similar to the ip access-list command, but it is IPv6-specific.
Note IPv6 ACLs are defined by a unique name (IPv6 does not support numbered ACLs). An IPv4 ACL and
an IPv6 ACL cannot share the same name.
See the
for more information on filtering IPv6 traffic based on IPv6 option headers and optional, upper-layer
protocol-type information. See the "Examples" section for an example of a translated IPv6 ACL
configuration.
Every IPv6 ACL has implicit permit icmp any any nd-na, permit icmp any any nd-ns, and deny ipv6
Note
any any statements as its last match conditions. The two permit conditions allow ICMPv6 neighbor
discovery. To disallow ICMPv6 neighbor discovery and to deny icmp any any nd-na or icmp any any
nd-ns, there must be an explicit deny entry in the ACL. For the implicit deny ipv6 any any statement
to take effect, an IPv6 ACL must contain at least one entry.
