Related Commands 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). • ip access-list extended - create an extended ACL. • permit - assign a permit filter for IP packets. • permit udp - assign a permit filter for UDP packets. seq arp (for Extended MAC ACLs) Configure an egress filter with a sequence number that filters ARP packets meeting this criteria. This command is supported only on 12port 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 a complete description on all of the keywords and variables that are available with this command, refer the topic of this command discussed earlier in this guide. Syntax Parameters seq sequence-number {deny | permit} arp {destination-mac-address mac-addressmask | any} vlan vlan-id {ip-address | any | opcode code-number} [count [byte]] [order] [log [interval minutes] [threshold-in-msgs [count]] [monitor] To remove this filter, use the no seq sequence-number command. 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. You can enter a threshold in the range of 1-100. interval minutes (OPTIONAL) Enter the keyword interval followed by the time period in minutes at which ACL logs must be generated. You can enter an interval in the range of 1-10 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 5 minutes. By default, flow-based monitoring is not enabled. Command Modes CONFIGURATION-EXTENDED-ACCESS-LIST Command History This guide is platform-specific.
