debugging mpls l2vpn service

Function

The debugging mpls l2vpn service command enables debugging for L2VPN services.

Format

Parameters

Parameter	Description	Value
all	Indicates all Debugging switches of the current module.	-
ccc	Indicates CCC L2VPN debugging functions of the current module.	-
pwe3	Indicates PWE3 L2VPN debugging functions of the current module.	-
peerIp	Specifies the peer IP address of the PW.	The value is in dotted decimal notation.
vcId	Specifies the LSR ID of the remote device on the PW.	The value is an integer ranging from 1 to 4294967295.
atm-1to1-vcc	One PW carries the ATM cells of one PVC.	-
atm-1to1-vpc	One PW carries the ATM cells of one PVP.	-
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	One PW carries the ATM cells of multiple PVPs.	-
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.	-
ip-interworking	Enables static PW interworking when devices in the interworking are all provided by Huawei.	-
ip-layer2	Enables IP interworking for an LDP PW between a Huawei device and a non-Huawei device. ip-layer2 is required for 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.	-
vsi	Indicates VSI L2VPN debugging functions of the current module.	-
vsiName	Specifies the name of a VSI.	The value is a string of 1 to 31 case-sensitive characters, spaces not supported.
kompellavll	Enables debugging for BGP VPWS.	-

Usage Guidelines

Usage Scenario

To check debugging information about L2VPN services, run the debugging mpls l2vpn service command to enable debugging for L2VPN services first.

Precautions

The debugging information is output on the screen. For less impact on performance, do not output too much non-debugging information.

Example

# Enable debugging for all L2VPN services.
