Dell 9.7(0.0) manual Permit for Standard IP ACLs

Related Commands

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).

permit — configures a MAC address filter to pass packets.

seq — configures a MAC address filter with a specified sequence number.

permit (for Standard IP ACLs)

To permit packets from a specific source IP address to leave the switch, configure a filter.

Syntaxpermit {source [mask] any host ip-address} [count [byte]] [dscp value] [order] [fragments] [log [interval minutes] [threshold-in-msgs [count]] [monitor]

To remove this filter, you have two choices:

•Use the no seq sequence-numbercommand if you know the filter’s sequence number.

•Use the no permit {source [mask] any host ip-address} command.

Parameters	(OPTIONAL) Enter the keyword log to enable the triggering
log
	of ACL log messages.
threshold-in	(OPTIONAL) Enter the threshold-in-msgskeyword
msgs count	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	(OPTIONAL) Enter the keyword interval followed by the
minutes	time period in minutes at which ACL logs must be generated.
	The threshold 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
