Version Description
6.5.1.0 Expanded to include the optional QoS order priority for the ACL entry.
Usage Information
Dell EMC Networking OS supports one ingress and one egress IP ACL per interface.
Prior to Dell EMC Networking OS version 7.8.1.0, names are up to 16 characters long.
The number of entries allowed per ACL is hardware-dependent. For detailed specifications on entries allowed per
ACL, refer to your line card documentation.
Example
DellEMC(conf)# ip access-list standard TestList
DellEMC(config-std-nacl)#

Commands
• ip access-list extended — create an extended access list.
• show config — display the current configuration.
permit
To permit packets from a specific source IP address to leave the switch, configure a filter.
Syntax
permit {source [mask]| any | host ip-address} [count [bytes] | log] [dscp
value] [ecn value] [fragments] [monitor ] [no-drop] [order]
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.
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.
count (OPTIONAL) Enter the keyword count to count the packets.
bytes (OPTIONAL) Enter the keyword bytes to count the bytes.
log (OPTIONAL) Enter the keyword log to enter ACL matches in the log.
dscp (OPTIONAL) Enter the keyword dcsp to match the IP DSCP values. The range is from 0
to 63.
ecn (OPTIONAL) Enter the keyword ecn to match the ECN bits. The range is from 0 to 3.
order (OPTIONAL) Enter the keyword order to specify the QoS order 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).
monitor (OPTIONAL) Enter the keyword monitor to describe the traffic that you want to
monitor and the ACL in which you are creating the rule is applied to the monitored
interface.
NOTE: For more information, see “Flow-based Monitoring” in the Port
Monitoring section of the Dell EMC Networking OS Configuration Guide .
fragments Enter the keyword fragments to use ACLs to control packet fragments.
no-drop Enter the keywords no-drop to match only the forwarded packets.
Defaults Not configured.
