show access-list identifier

Syntax

show access-list identifier [ config ]

Description

Displays detailed information on the content of a specific ACL configured in the running-config file.

NOTE:

This information also appears in the show running display. If you execute write memory after configuring an ACL, it also appears in the show config display.

For information on IPv4 ACL operation, see the latest version of the Aruba-OS Switch Access Security Guide for your switch.

Example

Viewing the content of a specific ACL

Suppose you configured the following two ACLs in the switch:

Identifier

Type

Desired action

Accounting

IPv6

  • Permit Telnet traffic from these two IPv6 addresses:
    • 2001:db8:0:1af::10: 14

    • 2001:db8:0:1af::10: 24

  • Deny Telnet traffic from all other devices in the same subnet.

  • Permit all other IPv6 traffic from the subnet.

  • Deny and log any IPv6 traffic from any other source.

List-120

IPv4 Extended

  • Permit any TCP traffic from 10.30.133.27 to any destination.

  • Deny any other IP traffic from 10.30.133.(1 - 255).

  • Permit all other IP traffic from any source to any destination.
