include: Displays all lines that match the specified regular expression.

regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters.

Usage guidelines

The output varies by mirroring group types and is sorted by mirroring group numbers.

Examples

# Display information about all the mirroring groups.

<Sysname> display mirroring-group all

mirroring-group 3:

    type: local

    status: active

    mirroring port:

        GigabitEthernet1/0/1  inbound

Parameters

group-id: Specifies the number of a mirroring group. The value is 1. The specified mirroring group must already exist.

mirroring-port-list: Specifies a space-separated list of up to eight port items. Each item specifies a single port or a port range in the form of interface-type interface-number1 to interface-type interface-number2. The value for the interface-number2 argument must be equal to or greater than the value for the interface-number1 argument.

both: Mirrors both inbound and outbound packets.

inbound: Mirrors only inbound packets.

outbound: Mirrors only outbound packets.

Usage guidelines

When you remove a source port from a mirroring group, make sure the direction specified in the undo command matches the port mirroring direction.

Examples

# Create local mirroring group 1 to monitor the bidirectional traffic of GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] mirroring-group 1 local

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