View

System view/Ethernet port view

Parameter

group-id: The number of a port mirroring group, in the range 1 to 20.

monitor-port monitor-port: Specifies the destination port for port mirroring. monitor-port is available in system view only, instead of in Ethernet port view.

Description

Use the mirroring-group monitor-port command to configure the destination port.

Use the undo mirroring-group monitor-port to remove the configuration of the destination port.

Note the following when you configure the destination port:

l           LACP and STP must be disabled on the destination port.

l           The destination port for remote mirroring must be an Access port.

l           After a port is configured as a reflector port, the switch does not allow you to change the port type or its default VLAN ID.

Example

# Configure GigabitEthernet1/1/4 as the source port

<H3C> system-view

System View: return to User View with Ctrl+Z.

[H3C] mirroring-group 1 monitor-port Gigabitethernet1/1/4

1.1.5  mirroring-group reflector-port

Syntax

mirroring-group group-id reflector-port reflector-port

undo mirroring-group group-id reflector-port reflector-port

View

System view/Ethernet port view

Parameter

group-id: The number of a port mirroring group, in the range 1 to 20.

reflector-port reflector-port: Specifies the reflector port. reflector-port is available in system view only, instead of in Ethernet port view.

Description

Use the mirroring-group reflector-port command to specify the reflector port.

Use the undo mirroring-group reflector-port command to remove the configuration of the reflector port.

Note the following when you configure the reflector port:

l           The reflector port must be an Access port.

l           LACP and STP must be disabled on the reflector port.

undo monitor-port

View

Ethernet port view

Parameter

None

Description

Use the monitor-port command to configure the destination port.

Use the undo monitor-port command to remove the configuration of the destination port.

You can only configure one destination port on a switch, and all mirrored packets will be sent to the destination port.

Related command: display mirroring-group

Example

# Configure GigabitEthernet1/1/4 as the destination port.

<H3C> system-view

System View: return to User View with Ctrl+Z.

[H3C] interface GigabitEthernet1/1/4

1.1.9  remote-probe vlan

Syntax

remote-probe vlan enable

undo remote-probe vlan enable

View

VLAN view

Parameter

None

Description

Use the remote-probe vlan enable command to configure the current VLAN as the remote-probe VLAN.

After this command is executed, the system first checks whether the current VLAN is a dynamic VLAN. If yes, the command will fail, and the system prompts “Can not set dynamic VLAN as remote-probe VLAN!”.

Use the undo remote-probe vlan enable command to configure the remote-probe VLAN as a normal VLAN.

Before defining the remote-probe VLAN, make sure that no Access or Hybrid port belongs to this VLAN. If any Trunk port exists in this VLAN, the port PVID cannot be the ID of remote-probe VLAN. After setting a VLAN as remote-probe VLAN, it is recommended not to add Access or Hybrid port to the VLAN.

Example

# Configure VLAN 5 as remote-probe vlan.

<H3C> system-view

System View: return to User View with Ctrl+Z.

[H3C] vlan 5

[H3C-vlan5] remote-probe vlan enable
