Dell S6000 FTOS 9.0(2.0) Command Line Reference Guide for the System - Page 127

port port destination mask count byte order fragments Enter the application layer port number. Enter two port numbers if using the range logical operand. Range: 0 to 65535. The following list includes some common TCP port numbers: • 23 = Telnet • 20 and 21 = FTP • 25 = SMTP • 169 = SNMP Enter the IP address of the network or host to which the packets are sent. Enter a network mask in /prefix format (/x) or A.B.C.D. The mask, when specified in A.B.C.D format, may be either contiguous or non-contiguous. (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 Command History CONFIGURATION-EXTENDED-ACCESS-LIST 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 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 Information Service" chapter of the FTOS Configuration Guide for more information. The S-Series cannot count both packets and bytes, so when you enter the count byte options, only bytes are incremented. 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 (gt, lt, 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. For example, an ACL rule with TCP port range 4000 - 8000 uses 8 entries in the CAM: Rule# Data Mask From To #Covered Access Control Lists (ACL) | 127
