deny ether-type (for Extended MAC ACLs)

Configure an egress filter that drops specified types of Ethernet packets on egress ACL supported line cards. (For more information, refer to your line card documentation).

Syntax

deny ether-type protocol-type-number { destination-mac-address mac-address-mask | any} vlan vlan-id { source-mac-address mac-address-mask | any} [count [byte]] [order] [log [interval minutes] [threshold-in-msgs [count]] [monitor]

To remove this filter, you have two choices:

Use the no seq sequence-number command if you know the filter’s sequence number.
Use the no deny ether-type protocol-type-number { destination-mac-address mac-address-mask | any} vlan vlan-id { source-mac-address mac-address-mask | any} command.

Parameters

protocol-type-number	Enter a number from 600 to FFFF as the specific Ethernet type traffic to drop.
destination-mac-address mac-address-mask	Enter a MAC address and mask in the nn:nn:nn:nn:nn format. For the MAC address mask, specify which bits in the MAC address must match. The MAC ACL supports an inverse mask; therefore, a mask of ff:ff:ff:ff:ff:ff allows entries that do not match and a mask of 00:00:00:00:00:00 only allows entries that match exactly.
any	Enter the keyword `any` to match and drop specific Ethernet traffic on the interface.
vlan vlan-id	Enter the keyword `vlan` and then enter the VLAN ID to filter traffic associated with a specific VLAN. The range is 1 to 4094 and 1 to 2094 for ExaScale ( you can use IDs 1 to 4094). To filter all VLAN traffic, specify `VLAN 1`.
source-mac-address mac-address-mask	Enter a MAC address and mask in the nn:nn:nn:nn:nn format. For the MAC address mask, specify which bits in the MAC address must match. The MAC ACL supports an inverse mask; therefore, a mask of ff:ff:ff:ff:ff:ff allows entries that do not match and a mask of 00:00:00:00:00:00 only allows entries that match exactly.
count	(OPTIONAL) Enter the keyword `count` to count packets processed by the filter.
byte	(OPTIONAL) Enter the keyword `byte` to count bytes processed by the filter.
order	(OPTIONAL) Enter the keyword order to specify the QoS priority for the ACL entry. The range is from 0 to 254 (where 0 is the highest priority and 254 is the lowest; lower order numbers have a higher priority) If you did not use the keyword `order`, the ACLs have the lowest order by default (255).
log	(OPTIONAL) Enter the keyword `log` to enable the triggering of ACL log messages.
threshold-in msgs count	(OPTIONAL) Enter the `threshold-in-msgs` keyword followed by a value to indicate the maximum number of ACL logs that can be generated, exceeding which the generation of ACL logs is terminated with the `seq`, `permit`, or `deny` commands. The threshold range is from 1 to 100.
interval minutes	(OPTIONAL) Enter the keyword `interval` followed by the time period in minutes at which ACL logs must be generated. The time interval range is from of 1 to 10 minutes.
monitor	(OPTIONAL) Enter the keyword `monitor` when the rule is describing the traffic that you want to monitor and the ACL in which you are creating the rule is applied to the monitored interface.

Defaults

By default, 10 ACL logs are generated if you do not specify the threshold explicitly. The default frequency at which ACL logs are generated is five minutes. By default, flow-based monitoring is not enabled.

Command History

Version	Description
9.9(0.0)	Introduced on the FN IOM.
9.4(0.0)	Added support for flow-based monitoring on the MXL 10/40GbE Switch IO Module platforms.
9.3(0.0)	Added support for logging of ACLs on the MXL 10/40GbE Switch IO Module platforms.

Usage Information

When the configured maximum threshold is exceeded, generation of logs is stopped. When the interval at which ACL logs are configured to be recorded expires, the subsequent, fresh interval timer is started and the packet count for that new interval commences from zero. If ACL logging was stopped previously because the configured threshold is exceeded, it is re-enabled for this new interval.

If ACL logging is stopped because the configured threshold is exceeded, it is re-enabled after the logging interval period elapses. ACL logging is supported for standard and extended IPv4 ACLs, IPv6 ACLs, and MAC ACLs. You can configure ACL logging only on ACLs that are applied to ingress interfaces; you cannot enable logging for ACLs that are associated with egress interfaces.

You can activate flow-based monitoring for a monitoring session by entering the flow-based flow-based enable command in the Monitor Session mode. When you enable this capability, traffic with particular flows that are traversing through the ingress and egress interfaces are examined and, appropriate ACLs can be applied in both the ingress and egress direction. Flow-based monitoring conserves bandwidth by monitoring only specified traffic instead all traffic on the interface. This feature is particularly useful when looking for malicious traffic. It is available for Layer 2 and Layer 3 ingress and egress traffic. You may specify traffic using standard or extended access-lists. This mechanism copies all incoming or outgoing packets on one port and forwards (mirrors) them to another port. The source port is the monitored port (MD) and the destination port is the monitoring port (MG).
