Standard IP ACL Commands
When you create an ACL without any rule and then apply it to an interface, the ACL behavior reflects an implicit permit.
The platform supports both Ingress and Egress IP ACLs.
NOTE: Also refer to the Commands Common to all ACL Types and Common IP ACL Commands sections.
deny
To drop packets with a certain IP address, configure a filter.
Syntax
deny {source | 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 deny {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.
any Enter the keyword any to specify that all routes are subject to the filter.
host ip-address Enter the keyword host and then enter the IP address to specify a host IP address
only.
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 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.
