Chapter 1 Mirroring Configuration
1.1 Mirroring Overview
Mirroring refers to the process of copying packets that meet the specified rules to a destination port. Generally, a destination port is connected to a data detect device, which users can use to analyze the mirrored packets for monitoring and troubleshooting the network.
1.1.1 Traffic Mirroring
Traffic mirroring refers to the process of copying traffic flows that match specific ACLs to the specified destination port for packet analysis and monitoring. Before configuring traffic mirroring, you need to define ACLs required for flow identification.
1.1.2 Port Mirroring
Port mirroring refers to the process of copying the packets received or sent by the specified port to the destination port.
1.1.3 Remote Port Mirroring — RSPAN
Remote switched port analyzer (RSPAN) refers to remote port mirroring. It eliminates the limitation that the source port and the destination port must be located on the same switch. This feature makes it possible for the source port and the destination port to be located across several devices in the network, and facilitates the network administrator to manage remote switches.
The application of RSPAN is illustrated in the following figure:
There are three types of switches with the RSPAN enabled.
l Source switch: The monitored port resident switch. Through Layer 2 forwarding, it sends traffics to be mirrored to an intermediate switch or destination switch over the remote-probe VLAN.
l Intermediate switch: Switches between the source switch and destination switch on the network. An intermediate switch forwards mirrored traffic flows to the next intermediate switch or the destination switch. Circumstances can occur where no intermediate switch is present, if a direct connection exists between the source and destination switches.
l Destination switch: The remote mirroring destination port resident switch. It forwards mirrored traffic flows it received from the remote-probe VLAN to the monitoring device through the destination port.
Table 1-1 describes how the ports on various switches are involved in the mirroring operation.
Table 1-1 Ports involved in the mirroring operation
Switch |
Ports involved |
Function |
Source switch |
Source port |
Port monitored. It copies user data packets to the specified reflector port through local port mirroring. There can be more than one source port. |
Reflector port |
Receives user data packets that are mirrored on a local port. |
|
Trunk port |
Sends mirrored packets to the intermediate switch or the destination switch. |
|
Intermediate switch |
Trunk port |
Sends mirrored packets to the destination switch. Two Trunk ports are necessary for the intermediate switch to connect the devices at the source switch side and the destination switch side. |
Destination switch |
Trunk port |
Receives remote mirrored packets. |
Destination port |
Monitors remote mirrored packets |
To implement remote port mirroring, you need to define a special VLAN, called remote-probe VLAN, on a switch. All mirrored packets will be transferred from the source switch to the destination ports of the destination switch through this VLAN. Thus, the destination switch can monitor the port packets sent from the ports of the source switch. Remote-probe VLAN requires that:
l All ports connecting the devices in remote-probe VLAN are configured as the trunk ports.
l The default VLAN and management VLAN cannot be configured as remote-probe VLAN.
l Layer 2 interoperability must be ensured by configuration between the source and destination switches over the remote-probe VLAN.
Caution:
To ensure the normal packet mirroring, it is not recommended to perform any of the following operations on the remote-probe VLAN:
l Configuring a source port to the remote-probe VLAN that is used by the local mirroring group;
l Configuring a Layer 3 interface for the remote-probe VLAN;
l Configuring to run other protocol packets, or bear other service packets;
l Using remote-probe VLAN as a special type of VLAN, such as voice VLAN or protocol VLAN;
l Configuring other VLAN-related functions.

V. Configuration example
Network requirements:
l Switch A is connected to the data detect device through GigabitEthernet 1/1/2.
l GigabitEthernet 1/1/1, the Trunk port of Switch A, is connected to GigabitEthernet 1/1/1, the Trunk port of Switch B.
l GigabitEthernet 1/1/2, the Trunk port of Switch B, is connected to GigabitEthernet 1/1/1, the Trunk port of Switch C.
l GigabitEthernet 1/1/2, the port of Switch C, is connected to PC1.
The purpose is to use the data detect device to monitor and analyze the packets sent by PC1.
To meet the above purpose by using the RSPAN function, perform the following configuration:
l Define VLAN10 as the remote-probe VLAN.
l Define Switch A as the destination switch; configure GigabitEthernet 1/1/2, the port that is connected to the data detect device, as the destination port for remote mirroring. Set GigabitEthernet1/1/2 to an Access port, with STP and LACP functions disabled.
l Define Switch B as the intermediate switch.
l Define Switch C as the source switch, GigabitEthernet 1/1/2 as the source port for remote mirroring, and GigabitEthernet 1/1/3 as the reflector port. Set GigabitEthernet 1/1/3 to an Access port, with STP and LACP disabled.
