Users Guide

The following commands congure extended IP ACLs, which in addition to the IP address, also examine the packet’s protocol type.
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
Congure a lter that drops IP packets meeting the lter criteria.
Syntax
deny {ip | ip-protocol-number} {source mask | any | host ip-address}
{destination mask | any | host ip-address} [count [byte] | log] [dscp value]
[order] [monitor [session-ID]] [fragments] [no-drop]
To remove this lter, you have two choices:
• Use the no seq sequence-number command if you know the lter’s sequence number.
•
Use the no deny {ip | ip-protocol-number} {source mask | any | host ip-address}
{destination mask | any | host ip-address} command.
Parameters
ip Enter the keyword ip to congure a generic IP access list. The keyword ip species that
the access list denies all IP protocols.
ip-protocol-number Enter a number from 0 to 255 to deny based on the protocol identied in the IP protocol
header.
source Enter the IP address of the network or host from which the packets were sent.
mask Enter a network mask in /prex format (/x) or A.B.C.D. The mask, when specied in
A.B.C.D format, may be either contiguous or noncontiguous.
any Enter the keyword any to specify that all routes are subject to the lter.
host ip-address Enter the keyword host then the IP address to specify a host IP address.
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 that the lter processes.
byte (OPTIONAL) Enter the keyword byte to count bytes that the lter processes.
log (OPTIONAL, E-Series only) Enter the keyword log to enter ACL matches in the log.
dscp (OPTIONAL) Enter the keyword dcsp to match to the IP DCSCP values.
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).
monitor (OPTIONAL) Enter the keyword monitor then the session–ID to describe the trac
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. For more information, see
Flow-based Monitoring in the Port Monitoring section in the Dell Networking OS
Conguration 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.
