Table 299: Access List Summary Fields
Field
Description
ACL Identifier
The name or number that identifies the ACL. The permitted identifier depends
on the ACL type. Standard and Extended IPv4 ACLs use numbers within a set
range, and Named IPv4 and MAC ACLs use alphanumeric characters.
ACL Type
The type of ACL. The ACL type determines the criteria that can be used to match
packets. The type also determines which attributes can be applied to matching
traffic. IPv4 ACLs classify Layer 3 and Layer 4 IPv4 traffic, IPv6 ACLs classify
Layer 3 and Layer 4 IPv6 traffic, and MAC ACLs classify Layer 2 traffic. The ACL
types are as follows:
•
IPv4 Standard – Match criteria is based on the source address of IPv4
packets.
•
IPv4 Extended – Match criteria can be based on the source and destination
addresses, source and destination Layer 4 ports, and protocol type of IPv4
packets.
•
IPv4 Named – Match criteria is the same as IPv4 Extended ACLs, but the ACL
ID can be an alphanumeric name instead of a number.
•
IPv6 Named – Match criteria can be based on information including the
source and destination IPv6 addresses, source and destination Layer 4 ports,
and protocol type within IPv6 packets.
•
Extended MAC – Match criteria can be based on the source and destination
MAC addresses, 802.1p user priority, VLAN ID, and EtherType value within
Ethernet frames.
Rules Used
The number of rules currently configured for the ACL
Direction
Whether the packet is checked against the rules in an ACL when it is received on
an interface (Inbound) or after it has been received, routed, and is ready to exit
an interface (Outbound).
Interface
The interface(s) to which the ACL has been applied.
VLAN
Each VLAN to which the ACL has been applied.
Access Control List Configuration
Use the Access Control List Configuration page to configure rules for the existing
s on the system
and to view summary information about the rules that have been added to an ACL. Each ACL rule is
configured to match one or more aspects of traffic on the network. When a packet matches the
conditions in a rule, it is handled according to the configured action (permit or deny) and attributes.
Each ACL can have multiple rules, but the final rule for every ACL is an implicit deny all rule. For each
rule, a packet must match all the specified criteria in order for the specified rule action (Permit/Deny) to
take place.

To add an Access List Rule entry, select the ID of the ACL that will include the rule from the ACL
Identifier menu. Then, click
Add Rule
and configure the rule criteria and attributes. New rules cannot
be created if the maximum number of rules has been reached.
