Types of ACLs
A permit or deny policy for IPv6 traffic you want to filter is based on source and destination IPv6 address, plus other IPv6 protocol factors such as TCP/ UDP, ICMP, and DSCP.
Standard ACL: Use a standard ACL when you need to permit or deny traffic based on source IP address. Standard ACLs are also useful when you need to quickly control a performance problem by limiting traffic from a subnet, group of devices, or a single device. (This can block all inbound or outbound IP traffic from the configured source, but does not block traffic from other sources within the network.) This ACL type uses a numeric ID of 1 through 99 or an alphanumeric ID string. You can specify a single host, a finite group of hosts, or any host.
