Dell C9010 Modular Chassis Switch EMC Networking Command-Line Reference Guide - Page 228

Usage Information Example Related Commands The system supports one ingress and one egress IP ACL per interface. The number of entries allowed per ACL is hardware-dependent. For detailed information on the number entries allowed per ACL on the C9000, refer to the Content Addressable Memory (CAM) chapter in the C9000 Configuration Guide. Use this command in Configuration Terminal Batch mode to create a standard IP access list in a dualhoming setup. Dell(conf)#ip access-list standard TestList Dell(config-std-nacl)# ip access-list extended - creates an extended access list. show config - displays the current configuration. permit Configure a filter to permit packets from a specific source IP address to be processed and forwarded to another interface on the switch. C9000 Series Syntax Parameters permit {source [mask]| any | host ip-address}[count [byte]] [dscp value] [order] [fragments] [log [interval minutes] [threshold-in-msgs [count]] [monitor] To remove this filter, you have two choices: ● Use the no seq sequence-number command if you know the filter's sequence number. ● Use the no permit {source [mask] | any | host ip-address} command. source mask any host ip-address count byte dscp order fragments log threshold-in msgs count interval minutes Enter the IP address in dotted decimal format of the network from which the packet was sent. (OPTIONAL) 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. Enter the keyword any to specify that all routes are subject to the filter. Enter the keyword host then the IP address to specify a host IP address. (OPTIONAL) Enter the keyword count to count packets that the filter processes. (OPTIONAL) Enter the keyword byte to count bytes that the filter processes. (OPTIONAL) Enter the keyword dcsp to match to the IP DSCP values. (OPTIONAL) Enter the keyword order to specify the QoS priority for the ACL entry. The range is from 0 to 254 (where 0 is the highest priority and 254 is the lowest; lower-order numbers have a higher priority). If you do not use the keyword order, the ACLs have the lowest order by default (255). Enter the keyword fragments to use ACLs to control packet fragments. (OPTIONAL) Enter the keyword log to include ACL messages in the log. (OPTIONAL) Enter the threshold-in-msgs keyword followed by a value to indicate the maximum number of ACL logs that can be generated, exceeding which the generation of ACL logs is terminated with the seq, permit, or deny commands. The threshold range is from 1 to 100. (OPTIONAL) Enter the keyword interval followed by the time period in minutes at which ACL logs must be generated. The threshold range is from 1 to 10 minutes. 228 Access Control Lists (ACL)
