Parameters

group-id: Specifies a mirroring group by its ID. The value range for this argument is 1 to 4.

vlan-id: Specifies a VLAN by its ID.

Usage guidelines

You can configure remote probe VLANs only for remote source groups and remote destination groups.

When a VLAN is configured as a remote probe VLAN, use the VLAN for port mirroring exclusively.

The remote mirroring groups on the source device and destination device must use the same remote probe VLAN.

Only a static VLAN that already exists can be configured as a remote probe VLAN. A VLAN can be configured as the remote probe VLAN for only one mirroring group.

To delete a VLAN that is configured as a remote probe VLAN, remove the remote probe VLAN configuration first.

Examples

# Create remote source group 1 and configure VLAN 10 as its remote probe VLAN.

<Sysname> system-view

[Sysname] mirroring-group 1 remote-source

[Sysname] mirroring-group 1 remote-probe vlan 10

# Create remote destination group 2 and configure VLAN 20 as its remote probe VLAN.
