Command History
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 deny (IPv6 access-list configuration) and permit (IPv6 access-list configuration) commands
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.
access-list-name Name of the IPv6 access list. Names cannot contain a space or quotation
mark or begin with a numeric.
