This command displays summary information for all Mac Access lists and ACL (Access Control List) rule hit count of packets matching the configured ACL rule within an ACL. This counter value rolls-over on reaching the maximum value. There is a dedicated counter for each ACL rule. ACL counters do not interact with PBR counters.
For ACL with multiple rules, once a match occurs at any one specific rule, counters associated with this rule only get incremented (for example, consider an ACL with three rules, after matching rule two, counters for rule three would not be incremented).
For ACL counters, If an ACL rule is configured without RATE-LIMIT, the counter value is count of forwarded/discarded packets. (For example: For a burst of 100 packets, the Counter value is 100).
If the ACL rule is configured with RATE LIMIT, the counter value is the MATCHED packet count. If the sent traffic rate exceeds the configured limit, the counters still display matched packet count (despite getting dropped beyond the configured limit since match criteria is met) which would equal the sent rate. For example, if rate limit is set to 10 kbps and ‘matching‘ traffic is sent at 100 kbps, counters reflect a 100 kbps value. If the sent traffic rate is less than the configured limit, counters display only the matched packet count. Either way, only the matched packet count is reflected in the counters, irrespective of whether they get dropped or forwarded. ACL counters do not interact with diffserv policies.
Use the access list name to display detailed information of a specific MAC ACL.
Note
The command output varies based on the match criteria configured within the rules of an ACL.| Format | show mac access-lists [name] |
| Mode | Privileged EXEC |
| Rule Number | The ordered rule number identifier defined within the MAC ACL. |
| Action | The action associated with each rule. The possible values are Permit or Deny. |
| Source MAC Address | The source MAC address for this rule. |
| Source MAC Mask | The source MAC mask for this rule. |
| Committed Rate | The committed rate defined by the rate-limit attribute. |
| Committed Burst Size | The committed burst size defined by the rate-limit attribute. |
| Destination MAC Address | The destination MAC address for this rule. |
| Ethertype | The Ethertype keyword or custom value for this rule. |
| VLAN ID | The VLAN identifier value or range for this rule. |
| COS | The COS (802.1p) value for this rule. |
| Log | Displays when you enable logging for the rule. |
| Assign Queue | The queue identifier to which packets matching this rule are assigned. |
| Mirror Interface | On Broadcom 5650x platforms, the unit/slot/port to which packets matching this rule are copied. |
| Redirect Interface | On Broadcom 5650x platforms, the unit/slot/port to which packets matching this rule are forwarded. |
| Time Range Name | Displays the name of the time-range if the MAC ACL rule has referenced a time range. |
| Rule Status | Status (Active/Inactive) of the MAC ACL rule. |
| ACL Hit Count | The ACL rule hit count of packets matching the configured ACL rule within an ACL. |
