Cisco Catalyst 2960-X User Manual

•
It distributes the ACL information to any switch that joins the stack.
•
If packets must be forwarded by software for any reason (for example, not enough hardware resources),
the active switch forwards the packets only after applying ACLs on the packets.
•
It programs its hardware with the ACL information it processes.
Stack Member and ACL Functions
Stack members perform these ACL functions:
•
They receive the ACL information from the active switch and program their hardware.
•
A stack member configured as a standby switch, performs the functions of the active switch in the event
the active switch fails.
Active Switch Failure and ACLs
Both the active and standby switches have the ACL information. When the active switch fails, the standby
takes over. The new active switch distributes the ACL information to all stack members.
Standard and Extended IPv4 ACLs
This section describes IP ACLs.
An ACL is a sequential collection of permit and deny conditions. One by one, the switch tests packets against
the conditions in an access list. The first match determines whether the switch accepts or rejects the packet.
Because the switch stops testing after the first match, the order of the conditions is critical. If no conditions
match, the switch denies the packet.
The software supports these types of ACLs or access lists for IPv4:
•
Standard IP access lists use source addresses for matching operations.
•
Extended IP access lists use source and destination addresses for matching operations and optional
protocol-type information for finer granularity of control.
IPv4 ACL Switch Unsupported Features
Configuring IPv4 ACLs on the switch is the same as configuring IPv4 ACLs on other Cisco switches and
routers.
The following ACL-related features are not supported:
•
Non-IP protocol ACLs
•
IP accounting
•
Reflexive ACLs and dynamic ACLs are not supported.
•
ACL logging for port ACLs and VLAN maps
