Dell S3100 Command Line Reference Guide for the Series 9.100.0 - Page 205

Usage Information The order option is relevant in the context of the Policy QoS feature only. For more information, see the "Quality of Service" section of the Dell Networking OS Configuration Guide. NOTE: When you configure ACL logging and byte counters simultaneously, byte counters may display an incorrect value. Configure packet counters with logging instead. The S-Series cannot count both packets and bytes; when you enter the count byte options, only bytes increment. The monitor option is relevant in the context of flow-based monitoring only. For more information, refer to Port Monitoring. 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.

Syntax Parameters resequence access-list {ipv4 | mac} {access-list-name StartingSeqNum Step-toIncrement} ipv4 | mac access-list-name StartingSeqNum Step-toIncrement Enter the keyword ipv4or mac to identify the access list type to resequence. Enter the name of a configured IP access list, up to 140 characters. Enter the starting sequence number to resequence. The range is from 0 to 4294967290. Enter the step to increment the sequence number. The range is from 1 to 4294967290. Defaults Command Modes None • EXEC • EXEC Privilege Command History This guide is platform-specific.
