Edit Rule for Policy View


Use the Edit Rule for Policy View to create and edit rules for policies. To present the Edit Rule for Policy View, click the Quality of Service link in the Policy Configuration section of the Config Tool main menu. Then use the Select, Create, or Copy button.

The following figure shows an example of the Edit Rule for Policy View.



The following section describes the fields in the Edit Rule for Policy View.

New Rule Name
Specifies a name you give to a specific new rule.
Source/MaskLen
Specifies the IP source address with mask length.
Format: aaa.bbb.ccc.ddd[/len]
Example: 192.45.20.44/32
SPort/Mask
Specifies the TCP/UDP source port with mask length.
Dest/MaskLen
Specifies the IP destination address with mask length.
Format: number mask | service
Examples: ftp-data, telnet, any
DPort/Mask
Specifies the TCP/UDP destination port with mask length.
Format: sport/dport: number mask | service
Examples: ftp-data, telnet, any
Interface
Which network interface the rule should apply to.
Inbound
If Inbound is selected, the rule is applied to packets that are received at the specified interface. If the interface is any, the rule is applied to all received packets.
Outbound
If Outbound is selected, the rule is applied to packets before they are transmitted. The packets may be locally sourced or forwarded packets.

[Note] At least one checkbox (Inbound or Outbound) must be checked for a rule to take effect.


IPproto
IP protocol.
Examples: tcp | udp | number | any
Filter
Available options are: permit, deny, drop silent.
You must select a forwarding rule if the filter attribute is not deny or drop silent.
Priority
Specifies the priority of the flow that matches the rule. Available options are: high, med, normal, low. High is the highest priority, followed by med, normal, and low.
You can also use a number for the priority field, with zero being the highest priority. High maps to the numeric value zero (0); med maps to the numeric value one (1); normal maps to the numeric value two (2); and low maps to the numeric value three (3).
Forwarding Rule
Available default options are: switch, forward, cache. You must select a forwarding rule if the filter attribute is not deny or drop silent. Each GIGAswitch/IP Switch Controller and Gateway is shipped with three default Forwarding Rules: switch, forward and cache. The default value of any matches any possible value of the field. Matching rules are processed in strict first-in-first-match fashion. A packet is said to match a rule if the value carried in the packet has the same value of all fields of the rule. If a field also has a specified mask, the zero bits in the mask indicate don't care bits in the value with which the mask is associated. For example, if source port's mask is 0xff00, only the eight Most Significant Bits of the source port are used to compare. Only TCP/UDP can specify port information.
