port service-loopback group number

undo port service-loopback group

View

Ethernet interface view

Default Level

2: System level

Parameters

number: Service loopback group ID. The value range for the number argument is 1 to 1,024..

Description

Use the port service-loopback group command to assign the Layer-2 Ethernet interface to the specified service loopback group.

Use the undo port service-loopback group command to remove the Layer-2 Ethernet interface from the specified service loopback group.

Note that you cannot remove the last member port of a referenced service loopback group.

Examples

# Assign Layer-2 Ethernet interface Ethernet 2/0/1 to service loopback group 1.

<Sysname> system-view

[Sysname] interface ethernet 2/0/1

[Sysname-Ethernet2/0/1] port service-loopback group 1

service-loopback group

Syntax

service-loopback group number type { multicast-tunnel | tunnel } *

undo service-loopback group number

View

System view

Default Level

2: System level

Parameters

number: Service loopback group ID. The value range for the number argument is 1 to 1,024..

type: Specifies the service type of a service loopback group.

tunnel: Specifies the service type of a service loopback group as Tunnel.

multicast-tunnel: Specifies the service type of a service loopback group as Multicast tunnel.

Description

Use the service-loopback group command to create a service loopback group or change the service type of an existing service loopback group.

Use the undo service-loopback group command to remove a service loopback group.

Note that:

l          A service loopback group can be referenced by other features after its creation. Only after being referenced can a service loopback group process service traffic. A service loopback group can be referenced by multiple features at the same time.

l          You can change the service type of an existing service loopback group. For the change to be successful, you must ensure that the service group has not been referenced; the attributes of all member ports (if any) are not conflicting with the target service type; and no service loopback group has been created for the target service type, because only one service loopback group is allowed for a service type.

l          You can remove any service loopback group except the referenced ones.

Examples

# Configure service loopback group 1 to support the tunnel service.

<Sysname> system-view

[Sysname] service-loopback group 1 type tunnel
