TABLE 6 Syntax Descriptions
Arguments... Description...
ipv6 access-list <acl-name> Enables the IPv6 configuration level and defines the name of the IPv6 ACL.
The <acl-name> can contain up to 199 characters and numbers, but
cannot begin with a number and cannot contain any spaces or quotation
marks.
permit The ACL will permit (forward) packets that match a policy in the access list.
deny The ACL will deny (drop) packets that match a policy in the access list.
icmp Indicates the you are filtering ICMP packets.
protocol The type of IPv6 packet you are filtering. You can specify a well-known name
for some protocols whose number is less than 255. For other protocols, you
must enter the number. Enter “?” instead of a protocol to list the well-known
names recognized by the CLI. IPv6 protocols include:
AHP – Authentication Header
ESP – Encapsulating Security Payload
IPv6 – Internet Protocol version 6
SCTP – Stream Control Transmission Protocol
