Dell S6000 FTOS 9.0(2.0) Command Line Reference Guide for the System - Page 135

destination count byte order fragments Enter the IP address of the network or host to which the packets are sent. (OPTIONAL) Enter the keyword count to count packets processed by the filter. (OPTIONAL) Enter the keyword byte to count bytes processed by the filter. (OPTIONAL) Enter the keyword order to specify the QoS priority for the ACL entry. Range: 0-254 (where 0 is the highest priority and 254 is the lowest; lower order numbers have a higher priority) Default: If the order keyword is not used, the ACLs have the lowest order by default (255). Enter the keyword fragments to use ACLs to control packet fragments. Defaults Not configured. Command Modes CONFIGURATION-EXTENDED-ACCESS-LIST Command History Version 9.0.2.0 Version 8.3.11.1 Version 8.3.1.0 Version 9.0.2.0 Version 9.0.2.0 Version 6.5.10 Introduced on the S6000. Introduced on the Z9000. Added dscp keyword. Allows ACL control of fragmented packets for IP (Layer 3) ACLs. Added support for S-Series Expanded to include the optional QoS order priority for the ACL entry. Usage The order option is relevant in the context of the Policy QoS feature only. See the Quality of Service Information chapter of the FTOS Configuration Guide for more information.. Note: When ACL logging and byte counters are configured simultaneously, byte counters may display an incorrect value. Configure packet counters with logging instead. The S-Series cannot count both packets and bytes, so when you enter the count byte options, only bytes are incremented. Most ACL rules require one entry in the CAM. However, rules with TCP and UDP port operators (gt, lt, range) may require more than one entry. The range of ports is configured in the CAM based on bitmask boundaries; the space required depends on exactly what ports are included in the range. For example, an ACL rule with TCP port range 4000 - 8000 uses 8 entries in the CAM: Rule# Data Mask From To #Covered 1 0000111110100000 1111111111100000 4000 4031 32 2 0000111111000000 1111111111000000 4032 4095 64 3 0001000000000000 1111100000000000 4096 6143 2048 4 0001100000000000 1111110000000000 6144 7167 1024 5 0001110000000000 1111111000000000 7168 7679 512 6 0001111000000000 1111111100000000 7680 7935 256 7 0001111100000000 1111111111000000 7936 7999 64 8 0001111101000000 1111111111111111 8000 8000 1 Total Ports: 4001 But an ACL rule with TCP port lt 1023 takes only one entry in the CAM: Rule# Data Mask From To #Covered Access Control Lists (ACL) | 135
