Port mirroring
Port mirroring lets you select the network traffic of specific switch ports for analysis by
a network analyzer. For each port mirroring configuration (the switch supports up to
four), you can select many switch ports as source ports but only a single switch port as
the destination port. For each port mirroring configuration, you can configure how traffic
is mirrored on a source port by selecting packets that are received, transmitted, or both.
You can also apply an IP ACL or MAC ACL to filter the traffic that is being mirrored.
A packet that is copied to the destination port is in the same format as the original
packet. This means that if the mirror is copying a received packet, the copied packet is
VLAN-tagged or untagged as it was received on the source port. If the mirror is copying
a transmitted packet, the copied packet is VLAN-tagged or untagged as it is being
transmitted on the source port.
To set up a port mirroring configuration:
1. Launch a web browser.
2.
In the address field of your web browser, enter the IP address of the switch.
The login page displays.
3. Click the Main UI Login button.
The main UI login page displays in a new tab.
4. Enter admin as the user name, enter your local device password, and click the Login
button.
