(Optional) Configuring Port Mirroring in Integrated Mode

Context

To simplify port mirroring configuration, related commands have been integrated into a single command. Perform the following steps to configure port mirroring in integrated mode:

**Table 1** Interfaces supporting local mirroring
Interface Type	Mirrored Port	Observing Port
Layer 3 Ethernet main interfaces (including Eth-Trunk interfaces and a Layer 3 main interface configured as a BAS main interface)	Supported	Supported
BAS interface	Supported NOTE: When a VE interface functions as a BAS interface, local flow mirroring is supported only on the access VE interface in hardware loopback mode.	Not supported
Ethernet sub-interfaces (including Eth-Trunk interfaces)	Supported NOTE: After a sub-interface is configured as a dot1q, dot1q VLAN tag termination, QinQ VLAN tag termination, EVC, or BAS sub-interface, the sub-interface still supports mirroring.	Supported NOTE: After a sub-interface is configured as a dot1q VLAN tag termination, QinQ VLAN tag termination, or BAS sub-interface, the sub-interface does not support be configured as an observing port. The observing port can only be configured on the EVC sub-interface with untag or dot1q traffic encapsulation type.

Procedure

Run system-view
The system view is displayed.
Run interface interface-type interface-number
The interface view is displayed.
Run port-mirroring to { null0 | interface interface-type interface-number observe-index observe-index } { inbound | cpu-packet | outbound } [ user-defined-filter user-defined-filter-id ]
Port mirroring in integrated mode is configured.
Run commit
The configuration is committed.
