The mpls switch-l2vc encapsulation hard-pipe command enables the hard pipe function for a static MS-PW on an SPE.
The undo mpls switch-l2vc encapsulation hard-pipe command disables the hard pipe function for a static MS-PW on an SPE.
By default, the hard pipe function is not enabled for static MS-PWs.

| Parameter | Description | Value |
|---|---|---|
| peer-ip |
Specifies the peer IP address of an MS-PW. |
The value is in dotted decimal notation. |
| vc-id |
Specifies the VC ID of an MS-PW. |
The value is an integer ranging from 1 to 4294967295. |
| encapsulation |
Specifies the encapsulation type of an MS-PW. |
- |
| cesopsn-basic |
Specifies the PW encapsulation type as cesopsn-basic. |
- |
| ethernet |
This encapsulation type is used when Ethernet packets do not carry VLAN information. |
- |
| ip-interworking |
Enables heterogeneous media IP interworking between Huawei devices. |
- |
| ip-layer2 |
Enables heterogeneous media IP interworking between a Huawei device and a non-Huawei device. |
- |
| satop-e1 |
SAToP is insensitive to the E1 frame structure and encapsulates a whole E1 frame into a PW packet. |
- |
| satop-e3 |
SAToP is insensitive to the E3 frame structure and encapsulates a whole E3 frame into a PW packet. |
- |
| satop-t1 |
SAToP is insensitive to the T1 frame structure and encapsulates a whole T1 frame into a PW packet. |
- |
| vlan |
This encapsulation type is used when Ethernet packets carry VLAN information. |
- |
| cep |
This encapsulation type is used for CEP services. |
- |
| bandwidth bandwidth |
Specifies the bandwidth of an MS-PW. |
The value is an integer ranging from 16 to 100000000, in kbit/s. The default value is 0. |
| expand-ratio expand-ratio |
Specifies the bandwidth expansion ratio of an MS-PW. |
The value is an integer ranging from 0 to 100. The default value is 10. |
Usage Scenario
IP hard pipe is a pipe technology that establishes a static PW over a static bidirectional co-routed LSP to simulate an SDH leased line.
In an IP hard pipe scenario, if the endpoints of a static MS-PW do not support the hard pipe function, reserve bandwidth for the static MS-PW. After you run the mpls switch-l2vc hard-pipe command to specify bandwidth for a static MS-PW, the MS-PW will carry an SDH leased line service based on the specified bandwidth.Prerequisites
A static MS-PW has been created using the mpls switch-l2vc command.
Configuration Impact
After the hard pipe function is configured for an MS-PW, the MS-PW must recurse to a hard-pipe static bidirectional co-routed LSP again. The hard pipe function must be enabled for the two PW segments of an MS-PW separately to implement hard-pipe MS-PW.
