Configuring and Managing Security ACLs 357
Nortel WLAN Security Switch 2300 Series Configuration Guide
Setting an ICMP ACL
With the following command, you can use security ACLs to set Internet Control Message Protocol (ICMP)
parameters for the ping command:
set security acl ip acl-name {permit [cos cos] | deny} icmp {source-ip-addr mask
destination-ip-addr mask} [type icmp-type] [code icmp-code] [precedence
precedence] [tos tos] [before editbuffer-index | modify editbuffer-index] [hits]
An ICMP ACL can filter packets by source and destination IP address, TOS level, precedence, ICMP type,
and ICMP code. For example, the following command permits all ICMP packets coming from 192.168.1.3
and going to 192.168.1.4 that also meet the following conditions:
• ICMP type is 11 (Time Exceeded).
• ICMP code is 0 (Time to Live Exceeded).
• Type-of-service level is 12 (minimum delay plus maximum throughput).
• Precedence is 7 (network control).
23x0# set security acl ip acl-3 permit icmp 192.168.1.3 0.0.0.0 192.168.1.4 0.0.0.0 type
11 code 0 precedence 7 tos 12 before 1 hits
The before 1 portion of the ACE places it before any others in the ACL, so it has precedence over any later
ACEs for any parameter settings that are met.
For more information about changing the order of ACEs or otherwise modifying security ACLs, see “Modi-
fying a Security ACL” on page 369. For information about TOS and precedence levels, see the Nortel Mobility
System Software Command Reference. For CoS details, see “Class of Service” on page 355.
ICMP includes many messages that are identified by a type field. Some also have a code within that type.
Table 24 lists some common ICMP types and codes. For more information, see
http://www.iana.org/assignments/icmp-parameters.
