display mpls switch-l2vc

Function

The display mpls switch-l2vc command displays MS-PW information.

Format

display mpls switch-l2vc [ hard-pipe ] [ brief | state { up | down } | ip-address vc-id encapsulation { atm-1to1-vcc | atm-1to1-vpc | atm-aal5-pdu | atm-aal5-sdu | atm-nto1-vcc | atm-nto1-vpc | atm-trans-cell | cesopsn-basic | ethernet | ip-interworking | ip-layer2 | ppp | satop-e1 | satop-e3 | satop-t1 | vlan | cep } ]

Parameters

Parameter	Description	Value
hard-pipe	Indicates an IP hard pipe. Only the NetEngine 8000 F1A supports this parameter.	-
brief	Displays summary static MS-PW information.	-
state	Displays information about static MS-PWs with the specified state.	-
up	Displays information about static MS-PWs in the Up state.	-
down	Displays information about static MS-PWs in the Down state.	-
ip-address	Specifies the IP address of a peer PE (usually the LSR ID).	The value is in dotted decimal notation.
vc-id	Specifies a VC ID.	The ID is a decimal integer ranging from 1 to 4294967295.
encapsulation	Indicates the PW encapsulation type.	-
atm-1to1-vcc	One PW carries the cells of one PVC.	-
atm-1to1-vpc	One PW carries the AAL5 SDUs of one PVC.	-
atm-aal5-pdu	One PW carries the AAL5 PDUs of one PVC.	-
atm-aal5-sdu	One PW carries the AAL5 SDUs of one PVC.	-
atm-nto1-vcc	One PW carries the ATM cells of multiple PVCs.	-
atm-nto1-vpc	ATM cells are transmitted over PWE3 VCs.	-
atm-trans-cell	ATM cells are transmitted over PWE3 VCs.	-
cesopsn-basic	Specifies the PW encapsulation type as cesopsn-basic.	-
ethernet	This encapsulation type is used when Ethernet packets do not carry VLAN information.	-
fr	FR provides protocol standards for the data link layer and physical layer.	-
ip-interworking	Enables heterogeneous interworking between devices. Use IP interworking if interworking with a Huawei device is required.	-
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 on a PSN.	-

Usage Guidelines

Usage Scenario

If you do not specify any parameter, information about all MS-PWs is displayed. To check information about a hard-pipe static VPWS MS-PW after configuring it, run the display mpls switch-l2vc hard-pipe command. If pwId, interface, or state is not configured, information about all hard-pipe static MS-PWs is displayed.

Precautions

If no hard-pipe static MS-PW is configured when you run the display mpls switch-l2vc hard-pipe command, no information is displayed after the command is run.

Example

The actual command output varies according to the device. The command output here is only an example.
