Using the Edit Rule for Policy page, you can create and edit rules for Quality of Service (QoS) policies. You must create forwarding rules before you can implement QoS policies.


Note: The Software Rate Shaping, Hardware Rate Shaping, and Quality of Service (QoS) features are mutually exclusive; that is, you can use only one of these features at any given time.


New Rule Name field: The name of a new policy rule. Rule names must be unique within a policy. Rule names do not transfer across the network.
Range: Alphanumeric characters (no spaces).
Source/MaskLen field: Specifies the source IP address with filter mask length. The mask here is the number of bits the rule examines in the incoming address, not the subnet mask (if you put the subnet mask here, the rule would apply to the whole subnet address).
Examples: aaa.bbb.ccc.ddd/masklen (205.226.3.0/24) or hostname.masklen (myhost.ipsilon.com.24)
Range: Valid IP address and mask length, or any to allow everything.
Default: any (this specific option allows everything)

Dest/MaskLen field: Specifies the destination IP address with filter mask length. The mask here is the number of bits the rule examines in the incoming address, not the subnet mask (if you put the subnet mask here, the rule would apply to the whole subnet address).
Examples: aaa.bbb.ccc.ddd/masklen (205.226.3.0/24) or hostname.masklen (myhost.ipsilon.com.24)
Range: Valid IP address and mask length, or any to allow everything.
Default: any (this specific option allows everything)

Interface menu: Selects the interface to which this rule applies.
Options: any (allows everything), any of the current local physical interfaces.
Default: any (this specific option allows everything)

IPproto field: Specifies the protocol name or number.
Example: tcp, udp, icmp
Example: 20, 23, 25
Range: Valid protocol name or protocol number, or any to allow everything.
Default: any (this specific option allows everything)

SPort/Mask field: Specifies the Source port and mask, if needed, in hexidecimal format.
Examples: 1024, 1024 0xfff0, 1024/0xfff0, nfs, nfs 0xfff0, nfs/0xfff0
Range: number, number mask, number/mask, service, service mask, service/mask, or any to allow everything.
Default: any (this specific option allows everything)

DPort/Mask field: Specifies the Destination port and mask, if needed, in hexidecimal format.
Examples: 1024, 1024 0xfff0, 1024/0xfff0, nfs, nfs 0xfff0, nfs/0xfff0
Range: number, number mask, number/mask, service, service mask, service/mask, or any to allow everything.
Default: any (this specific option allows everything)
Inbound checkbox: Applies rule to inbound traffic.
Options: on/off
Default: off

Outbound checkbox: Applies rule to outbound traffic.
Options: on/off
Default: off

Actions for this rule field: Displays the rule action menus (Filter, Priority, and Forward) and their current settings.


Filter menu: Defines which one of three filters to apply. Permit allows all traffic. Deny rejects traffic and sends an ICMP message. Drop silent rejects traffic without sending an ICMP message.
Options: permit, deny, drop silent
Default: permit

Priority menu: Defines which one of four priorities to apply: high, medium, normal, or low. Higher priority traffic exits the switch first. High maps to 1, med maps to 2, normal maps to 2, and low maps to 3. You must select a forwarding rule if the Filter attribute is not deny or drop silent.
Options: high, med, normal, or low.
Default: high

Forward menu: Specifies which forwarding rule to apply. There are four default rules: switch, forward, cache, and any. See the Forwarding Rule Editing page inline help for definitions of these default forwarding rules.
Options: switch, forward, cache, any.
Default: switch

Apply button: Applies the parameters on the current page to the running system.
