seq 15 permit 30.1.2.0/24
Dell#
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 [session-ID]] [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 then the session–ID 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. The session–ID range is from 0 to 65535.
NOTE: For more information, see “Flow-based Monitoring” in the Port
Monitoring section of the Dell Networking OS Configuration Guide .
