Administrator Guide

Usage Information
The number of entries allowed per ACL is hardware-dependent. For detailed information on the number entries
allowed per ACL on the switch, refer to the Content Addressable Memory (CAM) chapter in the C9000 Series
Configuration Guide.
If you configure an extended IP ACL to be used only to filter protocol traffic for CoPP, you must enter the
keyword cpu-qos.
Use this command in Configuration Terminal Batch mode to configure the extended IP access list (IP ACL) in a
dual-homing setup.
Example
Dell(conf)#ip access-list extended TESTListEXTEND
Dell(config-ext-nacl)#

Commands
ip access-list standard — configures a standard IP access list.
show config — displays the current configuration.
permit
To pass IP packets meeting the filter criteria, configure a filter.
C9000 Series
Syntax
permit {source mask | any | host ip-address} {destination mask | any | host ip-
address} [count [bytes]] [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 deny {source mask | any | host ip-address} {destination mask | any |
host ip-address} command.
Parameters
source Enter the IP address in dotted decimal format of the network from which the packet was
sent.
mask (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.
any Enter the keyword any to specify that all routes are subject to the filter.
host ip-address Enter the keyword host then the IP address to specify a host IP address or hostname.
destination Enter the IP address of the network or host to which the packets are sent.
count (OPTIONAL) Enter the keyword count to count packets processed by the filter.
bytes (OPTIONAL) Enter the keyword bytes to count bytes processed by the filter.
dscp (OPTIONAL) Enter the keyword dcsp to match to the IP DSCP values. The range is from
0 to 63.
order (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).
fragments Enter the keyword fragments to use ACLs to control packet fragments.
log (OPTIONAL) Enter the keyword log to include ACL messages in the log.
threshold-in msgs
count
(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.
