qos hard-pipe bandwidth outbound

Function

The qos hard-pipe bandwidth outbound command configures an IP hard-pipe bandwidth.

The undo qos hard-pipe outbound command deletes the IP hard-pipe bandwidth.

By default, no IP hard-pipe bandwidth is configured.

This command is supported only on the NetEngine 8000 F1A.

Format

qos hard-pipe share-mode bandwidth bandwidth-value outbound

undo qos hard-pipe [ share-mode bandwidth bandwidth-value ] outbound

Parameters

Parameter	Description	Value
share-mode	Indicates the shared mode.	-
bandwidth-value	Specifies an IP hard-pipe bandwidth.	<bandwidth-value> varies with interfaces. For an Eth-Trunk interface: The value is an integer ranging from 1 to 4294967294, in Mbit/s. For a GE interface on which the port shaping <shaping-value> [ network-header-length <network-header-length> ] [ pbs <pbs-value> ] command is not configured to restrict the rate at which the interface sends packets: The minimum value is 1, and the maximum value is the interface bandwidth minus 20, in Mbit/s(reserved for soft pipe services). For a GE interface on which the port shaping <shaping-value> [ network-header-length <network-header-length> ] [ pbs <pbs-value> ] command is configured to restrict the rate at which the interface sends packets: The minimum value is 1, and the maximum value is the shaping value minus 20, in Mbit/s(reserved for soft pipe services).

Usage Guidelines

Usage Scenario

During network planning, traffic is classified as hard-pipe traffic and soft-pipe traffic based on interfaces. Hard-pipe traffic must have low delay and no packet loss and not be affected by soft-pipe traffic. Therefore, fixed bandwidth must be allocated to hard-pipe traffic on interfaces. This bandwidth is exclusively available to hard-pipe traffic.

Precautions

If some member interfaces of the Trunk do not support share-mode, or exclusive-mode, this command cannot be configured on the Trunk interface.

If an interface is bound to a VSI instance and VPLS hard pipe is enabled for the VSI instance using the hard-pipe enable command, the qos hard-pipe bandwidth command cannot be configured on the interface.

If both qos hard-pipe share-mode bandwidth, qos car, and car (traffic behavior view) are configured, the qos hard-pipe share-mode bandwidth command configuration overrides the car configuration.

Hard pipes work in exclusive mode, which prevents soft pipe service traffic from using the exclusive port. This ensures the desired bandwidth and latency for hard pipe services.

When the public-network interface of the TE LSP for the IP hard pipe is an inter-subcard trunk interface, each subcard applies for an IP hard pipe bandwidth, causing the IP hard pipe bandwidth consumption to multiply.

Example

# Configure GE 0/1/8 to reserve an IP hard-pipe bandwidth of 800 Mbit/s.
