MAC Clone:

It’s only available for WAN port. Click the <Restore Factory MAC>

button to restore the MAC address to the factory default value or

click the <Clone Current PC’s MAC> button to clone the MAC

address of the PC you are currently using to configure the Router.

Then click <Save> to apply.

Note:

To avoid a conflict of MAC address on the LAN, it’s not allowed to set the MAC address of the Router’s

LAN port to the MAC address of the current management PC.

4.3.4 Switch

Some basic switch port management functions are provided by TL-R470T+, which facilitates you to

monitor the traffic and manage the network effectively.

Statistics

Unicast:

Displays the number of normal unicast packets received or transmitted

on the port.

Broadcast:

Displays the number of normal broadcast packets received or

transmitted on the port.

Pause:

Displays the number of flow control frames received or transmitted on

the port.

Multicast:

Displays the number of normal multicast packets received or transmitted

on the port.

Undersize:

Displays the number of the received frames (including error frames) that

are less than 64 bytes.

Normal:

Displays the number of the received packets (including error frames) that

are between 64 bytes and the maximum frame length. The maximum

untagged frame this Router can support is 1518 bytes long and the

maximum tagged frame is 1522 bytes long.

Oversize:

Displays the number of the received packets (including error frames) that

are longer than the maximum frame

.

Total (Bytes):

Displays the total number of the received or transmitted packets

(including error frames).

Check the box and click the <Clear> button to clear the traffic statistics of the corresponding port.

Port Mirror

Port Mirror, the packets obtaining technology, functions to forward copies of packets from one/multiple

ports (mirrored port) to a specific port (mirroring port). Usually, the mirroring port is connected to a data

diagnose device, which is used to analyze the mirrored packets for monitoring and troubleshooting the

network.

General

Enable Port Mirror:

Check the box to enable the Port Mirror function. If unchecked, it will be

disabled.

Mode:

Select the mode for the port mirror function. Options include:

z

Ingress:

When this mode is selected, only the incoming packets

sent by the mirrored port will be copied to the mirroring port.

z

Egress:

When this mode is selected, only the outgoing packets sent

by the mirrored port will be copied to the mirroring port.

z

Ingress&Egress:

When this mode is selected, both the incoming

and outgoing packets through the mirrored port will be copied to the

mirroring port.

Port Mirror

Mirroring Port:

Select the Mirroring Port to which the traffic is copied. Only one port can

be selected as the mirroring port.

Mirrored Port:

Select the Mirrored Port from which the traffic is mirrored. One or multiple

ports can be selected as the mirrored ports.

The entry in Figure 4-15 indicates: The outgoing packets sent by port 1, port 2, port 3 and port 5

(mirrored ports) will be copied to port 4 (mirroring port).

Tips:

If both the mirrored port and the mirroring port are the LAN ports, these two LAN ports should be in the

same Port VLAN. For example, if port 3 (the mirroring port) and port 4 (the mirrored port) are the LAN

ports, the Port Mirror function can take effect only when port 3 and port 4 are in the same Port VLAN.

Application Example:

To monitor all the traffic and analyze the network abnormity for an enterprise’s network, please set the

Port Mirror function as below:

1)

Check the box before

Enable Port Mirror

to enable the Port Mirror function and select the

Ingress & Egress

mode.

2)

Select Port 3 to be the

Mirroring Port to monitor all the packets of the other ports.

3)

Select all the other ports to be the Mirrored Ports.

4)

Click the <Save> button to apply.

Egress Rate:

Specify the limit rate for the egress packets.

The first entry in Figure 4-16 indicates: The Ingress and Egress Limits are enabled for port 1. The

Ingress and Egress Rates are 1Mbps. That is, the receiving rate for all the ingress packets will not

exceed 1Mbps, and the transmitting rate for all the egress packets will not exceed 1Mbps.
