Command History This guide is platform-specific. For command information about other platforms, see the relevant Dell NetworkingOS Command Line Reference Guide.Version Description9.8(0.0P5) Introduced on the S4048-ON.9.8(0.0P2) Introduced on the S3048-ON.9.7(0.0) Introduced on the S6000–ON.9.4(0.0) Added support for flow-based monitoring on the S4810, S4820T, S6000, Z9000, andMXL 10/40GbE Switch IO Module platforms.9.3.0.0 Added support for logging of ACLs on the S4810, S4820T, Z9000, and MXL 10/40GbESwitch IO Module platforms.Usage Information When the configured maximum threshold is exceeded, generation of logs is stopped. When the interval at whichACL logs are configured to be recorded expires, the subsequent, fresh interval timer is started and the packetcount for that new interval commences from zero. If ACL logging was stopped previously because the configuredthreshold is exceeded, it is reenabled for this new interval.If ACL logging is stopped because the configured threshold is exceeded, it is reenabled after the logging intervalperiod elapses. ACL logging is supported for standard and extended IPv4 ACLs, standard and extended IPv6 ACLs,and standard and extended MAC ACLs. You can configure ACL logging only on ACLs that are applied to ingressinterfaces; 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 inthe Monitor Session mode. When you enable this capability, traffic with particular flows that are traversing throughthe ingress and egress interfaces are examined and, appropriate ACLs can be applied in both the ingress andegress direction. Flow-based monitoring conserves bandwidth by monitoring only specified traffic instead all trafficon the interface. This feature is particularly useful when looking for malicious traffic. It is available for Layer 2 andLayer 3 ingress and egress traffic. You may specify traffic using standard or extended access-lists. This mechanismcopies all incoming or outgoing packets on one port and forwards (mirrors) them to another port. The source portis the monitored port (MD) and the destination port is the monitoring port (MG).seq ether-type (for Extended MAC ACLs)Configure an egress filter with a specific sequence number that filters traffic with specified types of Ethernet packets. This command issupported only on 12-port GE line cards with SFP optics. For specifications, refer to your line card documentation.NOTE: Only the options that have been newly introduced in Release 9.3(0.0) and Release 9.4(0.0) are described here. For acomplete description on all of the keywords and variables that are available with this command, refer the topic of this commanddiscussed earlier in this guide.Syntax seq sequence-number {deny | permit} 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, use the no seq sequence-number command.Parameters log (OPTIONAL) Enter the keyword log to enable the triggering of ACL log messages.310 Access Control Lists (ACL)
