Brocade Communications Systems 6650 manual Num

Extended named ACL configuration

If you enable the software to display IP subnet masks in CIDR format, the mask is saved in the file in “/ mask-bits” format. To enable the software to display the CIDR masks, enter the ip show-subnet-lengthcommand at the global CONFIG level of the CLI. You can use the CIDR format to configure the ACL entry regardless of whether the software is configured to display the masks in CIDR format.

NOTE

If you use the CIDR format, the ACL entries appear in this format in the running-config and startup-config files, but are shown with subnet mask in the display produced by the show ip access-listcommand.

The destination-ip hostname parameter specifies the destination IP host for the policy. If you want the policy to match on all destination addresses, enter any.

The icmp-type icmp-numparameter specifies the ICMP protocol type:

•This parameter applies only if you specified icmp as the ip-protocolvalue.

•If you use this parameter, the ACL entry is sent to the CPU for processing.

•If you do not specify a message type, the ACL applies to all types of ICMP messages. The icmp-numparameter can be a value from 0 – 255.

The icmp-typeparameter can have one of the following values, depending on the software version the device is running:

•any-icmp-type

•echo

•echo-reply

•information-request

•log

•mask-reply

•mask-request

•parameter-problem

•redirect

•source-quench

•time-exceeded

•timestamp-reply

•timestamp-request

•traffic policy

•unreachable

•num

NOTE

The QoS options listed below are only available if a specific ICMP type is specified for the icmp-typeparameter and cannot be used with the any-icmp-typeoption above. See “QoS options for IP ACLs” on page 1734for more information on using ACLs to perform QoS.
