Dell C1048P Port Extender Networking Command-Line Reference Guide for the C900 - Page 263

Command History This guide is platform-specific. For command information about other platforms, refer to the relevant Dell Networking OS Command Line Reference Guide. The following is a list of the Dell Networking OS version history for this command. Version 9.9(0.0) 9.2(1.0) 8.3.19.0 8.3.11.1 8.3.7.0 8.3.1.0 8.2.1.0 8.1.1.0 7.6.1.0 7.5.1.0 7.4.1.0 6.5.10 Description Introduced on the C9010. Introduced on the Z9500. Introduced on the S4820T. Introduced on the Z9000. Introduced on the S4810. Added the keyword dscp. Allows ACL control of fragmented packets for IP (Layer 3) ACLs. Introduced on the E-Series ExaScale. Introduced on the S-Series. Introduced on the C-Series. Added support for non-contiguous mask and added the monitor option. . Expanded to include the optional QoS order priority for the ACL entry. Usage Information Use the order option only when you use policy-based QoS on the switch. For more information, refer to the Quality of Service chapter of the C9000 Series Configuration Guide. When you use the log option, the CP processor logs detail the packets that match. Depending on how many packets match the log entry and at what rate, the CP may become busy as it has to log these packets' details. Use the monitor option only when you are using flow-based monitoring. For more information, refer to the Port Monitoring chapter of the C9000 Series Configuration Guide. 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 five minutes. By default, flow-based monitoring is not enabled. NOTE: When ACL logging and byte counters are configured simultaneously, byte counters may display an incorrect value. Configure packet counters with logging instead. Most ACL rules require one entry in the CAM. However, rules with TCP and UDP port operators (for example, gt, lt, or range) may require more than one entry. The range of ports is configured in the CAM based on bit mask boundaries; the space required depends on exactly what ports are included in the range. Example An ACL rule with a TCP port range of 4000-8000 uses eight entries in the CAM.
