deny ether-type (for Extended MAC ACLs

Page 293 highlights

Version 9.4(0.0) Description Added support for flow-based monitoring on the S4810, S4820T, S6000, and Z9000 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 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). 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 log threshold-in msgs count interval minutes monitor (OPTIONAL) Enter the keyword log to enable the triggering of ACL log messages. (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. (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 1 to 10 minutes. (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.

Version
Description
9.4(0.0)
Added support for flow-based monitoring on the S4810, S4820T, S6000, and Z9000
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
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).
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
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 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.
