3Com 10014298 Setting Line Limit, You can set line limit at a single port, Setting the Line Rate

Configuring QoS 165

Setting Line Limit

Line limit refers to limiting the total rate at the port. The adjustment step for the line rate of the Switch 7750 is 1Mbps.

Perform the following configurations in QoS view.

Table 178 Setting the Line Rate

Operation	Command
Set the line limit	line-ratetarget-rate
Remove the line limit	undo line-rate

You can set line limit at a single port.

Setting Traffic Bandwidth

You can set desired traffic bandwidth to ensure target services.

Perform the following configurations in QoS view.

Table 179 Setting Traffic Bandwidth

Operation	Command
Set traffic bandwidth	traffic-bandwidth outbound { ip-group {
	acl-number acl-name } [ rule rule ]
	link-group{ acl-number acl-name } [ rule
	rule ] } min-guaranteed-bandwidth
	max-guaranteed-bandwidth weight
Remove traffic bandwidth setting	undo traffic-bandwidth outbound {
	ip-group{ acl-number acl-name } [ rule rule
	] link-group{ acl-number acl-name } [ rule
	rule ] }

Setting Traffic Redirection

Traffic redirection refers to changing packet forwarding direction, that is, forwarding packets to CPU or other ports.

Perform the following configurations in QoS view.

Table 180 Setting Traffic Redirection

Operation	Command
Set traffic redirection	traffic-redirect inbound { ip-group {
	acl-number acl-name } [ rule rule ]
	link-group{ acl-number acl-name } [ rule
	rule ] } { cpu interface { interface-name
	interface-type interface-num } }
Remove traffic redirection	undo traffic-redirect inbound { ip-group {
	acl-number acl-name } [ rule rule ]
	link-group{ acl-number acl-name } [ rule
	rule ] }

Note that the packets cannot be forwarded normally when they are redirected to the CPU.

Traffic redirection is only available to the permitted rules in ACL.
