Creating and Committing a Security ACL 381

The simplest security ACL permits or denies packets from a source IP address:

set security acl ip acl-name{permit [cos cos] deny} source-ip-addr mask any} [before editbuffer-indexmodify editbuffer-index] [hits]

For example, to create ACL acl-1that permits all packets from IP address 192.168.1.4, type the following command:

WX1200# set security acl ip acl-1 permit 192.168.1.4 0.0.0.0

With the following basic security ACL command, you can specify any of the protocols supported by MSS:

set security acl ip acl-name{permit [cos cos] deny}

{protocol-number}{source-ip-addr mask any} [[precedence precedence] [tos tos] [dscp codepoint]] [before editbuffer-index modify editbuffer-index] [hits]

The following sample security ACL permits all Generic Routing Encapsulation (GRE) packets from source IP address 192.168.1.11 to destination IP address 192.168.1.15, with a precedence level of 0 (routine), and a type-of-service (TOS) level of 0 (normal). (For more information about type-of-service and precedence levels, see the Wireless LAN Switch and Controller Command Reference.) GRE is protocol number 47.

WX1200# set security acl ip acl-2 permit cos 2 47 192.168.1.11 0.0.0.0 192.168.1.15 0.0.0.0 precedence 0 tos 0 hits

The security ACL acl-2described above also applies the CoS level 2 (medium priority) to the permitted packets. (For CoS details, see “Class of Service” on page 382.) The keyword hits counts the number of times this ACL affects packet traffic.

Table 30 lists common IP protocol numbers. (For a complete list of IP protocol names and numbers, see www.iana.org/assignments/protocol-numbers.) For commands that set security ACLs for specific protocols, see the following information:
