Add Rules to ACL ■ Priority - Defines the ACL priority. ACLs are checked on the first fit basis. The ACL priority defines the ACL order in the ACL list. ■ Protocol - Indicates the protocol in the ACE to which the packet is matched. The possible fields are: ■ Select from List - Selects a protocol on which ACE can be based. ■ Protocol ID - Adds user-defined protocols by which packets are matched to the ACE. Each protocol has a specific protocol number which is unique. The possible field range is 0-255. ■ Source Port - Indicates the source port that is used for matched packets. Enabled only when TCP or UDP are selected in the Protocol list. The field value is either user defined or Any. If Any is selected the IP based ACL is applied to any source port.

Click
Device > ACL > IP Based ACL > Setup
. The
IP Based ACL Setup
Page
opens:
Figure 33
IP Based ACL Setup Page
The
IP Based ACL Setup Page
contains the following fields:
■
Selection ACL
— Selects the ACL to be bound.
■
Create ACL
— Defines a new user-defined IP based ACL.
Add Rules to ACL
■
Priority
— Defines the ACL priority. ACLs are checked on the first fit
basis. The ACL priority defines the ACL order in the ACL list.
■
Protocol
— Indicates the protocol in the ACE to which the packet is
matched. The possible fields are:
■
Select from List
— Selects a protocol on which ACE can be based.
■
Protocol ID
— Adds user-defined protocols by which packets are
matched to the ACE. Each protocol has a specific protocol number
which is unique. The possible field range is 0-255.
■
Source Port
— Indicates the source port that is used for matched
packets. Enabled only when TCP or UDP are selected in the Protocol
list. The field value is either user defined or
Any
. If
Any
is selected the
IP based ACL is applied to any source port.
