interval minutes monitor (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. Command Modes CONFIGURATION-EXTENDED-ACCESS-LIST Command History Version Description 9.9(0.0) Introduced on the C9010. 9.5(0.1) Introduced on the Z9500. 9.4(0.0) Added support for flow-based monitoring on the S4810, S4820T, S6000, and Z9000 platforms. 9.3(0.0) Added support for logging of ACLs on the S4810, S4820T, 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). ip address Assign a primary and secondary IP address to the interface. C9000 Series Syntax ip address {ip-address mask [secondary] | dhcp} To delete an IP address from an interface, use the no ip address [ip-address] command. Parameters ip-address mask Enter an IP address in dotted decimal format. Enter the mask of the IP address in slash prefix format (for example, /24). IPv4 Routing 993
