To configure port and VLAN mirroring:
STEP 1 Click Administration > Diagnostics > Port and VLAN Mirroring. 
STEP  2 If your switch supports the RSPAN VLAN feature, enter the following information: 
• RSPAN VLAN—Check Enable to enable RSPAN VLAN mirroring. 
• RSPAN VLAN ID—Select the VLAN to be mirrored. When you configure a 
RSPAN mirroring session, you should select this VLAN as the RSPAN VLAN. 
STEP  3 Click Add to add a SPAN or RSPAN mirroring session. 
STEP  4 Enter the following information:
• Session ID—Select the identifier for the mirroring session. 
• Session Type—Select one of the following options: 
-
Local Port Based
—Copies TX, RX, or both TX and RX traffic from each 
port to the destination port. 
-
Local VLAN Based
—Copies traffic from the local VLAN to the destination 
port. 
-
RSPAN Source Session
—Utilizes a VLAN to copy traffic from a source 
port or a source VLAN to another device. 
-
RSPAN Destination Session
—Utilizes a VLAN to copy traffic from a 
destination port to another device. 
STEP  5 If Local Port Based is selected, enter the following information: 
• Destination Port—Select the analyzer port to where packets are copied. A 
network analyzer, such as a PC running Wireshark, is connected to this port. 
• Allow Ingress Packets—Check Enable to allow the destination port to send 
or receive normal packets. 
• Source Port—Select the source ports from where traffic is mirrored and the 
type of traffic to be mirrored to the analyzer port. The options are: 
- Rx Only—Port mirroring on incoming packets. 
- Tx Only—Port mirroring on outgoing packets.
- Tx and Rx—Port mirroring on both incoming and outgoing packets.
- N/A—Traffic from this port is not mirrored.
