# Display information about port mirroring group 1.

<Sysname> display mirroring-group 1

mirroring-group 1:

    type: local

    status: active

    mirroring port:

        GigabitEthernet3/0/1  inbound

        GigabitEthernet3/0/2  both

    monitor port : GigabitEthernet3/0/3

Default Level

2: System level

Parameters

group-id: Specifies the number of the port mirroring group to be created or removed. Its value range is 1 through 4.

local: Creates a local mirroring group or removes all local mirroring groups with the undo command.

Description

Use the mirroring-group command to create a port mirroring group.

Use the undo mirroring-group command to remove the specified port mirroring group or groups.

By default, no port mirroring groups exist.

Examples

# Create a local mirroring group numbered 1.

<Sysname> system-view

[Sysname] mirroring-group 1 local

mirroring-group mirroring-port

Syntax

mirroring-group group-id mirroring-port mirroring-port-list { both | inbound | outbound }

undo mirroring-group group-id mirroring-port mirroring-port-list { both | inbound | outbound }

Default Level

2: System level

Parameters

group-id: Number of a port mirroring group, in the range 1 through 4.

mirroring-port-list: A list of ports/port ranges to be assigned to or removed from the port mirroring group specified by group-id. The total number of single ports plus port ranges cannot exceed eight. In the list, a single port takes the form of interface-type interface-number. A port range takes the form interface-type start-interface-number to interface-type end-interface-number, where the end port number must be greater than the start port number.

both: Mirrors both inbound and outbound packets on the specified port(s).

inbound: Mirrors only inbound packets on the specified port(s).

outbound: Mirrors only outbound packets on the specified port(s).

Description

Use the mirroring-group mirroring-port command to assign ports to a mirroring group as mirroring ports.

Use the undo mirroring-group mirroring-port command to remove mirroring ports from the mirroring group.

Note that:

l          When removing a mirroring port from a mirroring group, make sure the traffic direction you specified in the undo mirroring-group mirroring-port command matches the actual monitored direction of the port.

l          You cannot assign mirroring ports to a non-existent port mirroring group.

Related commands: mirroring-group.

Examples

# Create local mirroring group 1, configure GigabitEthernet 3/0/1 as its mirroring port, and configure to mirror both inbound and outbound packets on GigabitEthernet 3/0/1.

<Sysname> system-view

[Sysname] mirroring-group 1 local

[Sysname] mirroring-group 1 mirroring-port gigabitethernet 3/0/1 both

# Remove GigabitEthernet 3/0/1 from local mirroring group 1.

<Sysname> system-view

[Sysname] undo mirroring-group 1 mirroring-port gigabitethernet 3/0/1 both

mirroring-group monitor-port

Syntax

mirroring-group group-id monitor-port monitor-port-id

undo mirroring-group group-id monitor-port monitor-port-id

View

System view

Default Level

2: System level

Parameters

group-id: Number of a mirroring group, in the range 1 through 4.

monitor-port-id: Port to be assigned to the specified mirroring group as the monitor port. The argument takes the form of interface-type interface-number, where interface-type specifies the port type and interface-number specifies the port number.

Description

Use the mirroring-group monitor-port command to assign a port to a mirroring group as the monitor port.

Use the undo mirroring-group monitor-port command to remove the monitor port from the mirroring group.

In a local mirroring group, you must configure a monitor port. From this port, mirrored packets are sent to the monitor device for analysis.

Note that:

l          Before assigning a port to a port mirroring group, make sure that the mirroring group already exists.

l          In a mirroring group, you can configure only one monitor port. This port must not belong to any other mirroring group.

l          The monitor port can be an aggregation group member port.

Related commands: mirroring-group.

[Sysname] mirroring-group 1 local

[Sysname] mirroring-group 1 monitor-port gigabitethernet 3/0/1
