Mirroring

- Mirroring This port’s network traffic will receive the

mirrored traffic from the port listed below for analysis:

• Mirroring Port Enter the number of the port that

will be mirrored.

• Link Negotiation The default is Auto, enabling

Ethernet autonegotiation. This is the appropriate

configuration for almost all circumstances. Never

use Manual unless the device being connected

to the port has also been set manually; if so, then

switch to Manual to disable autonegotiation and

enable manual configuration of duplex and speed:

• Full Duplex (Available for RJ45 ports only.) Ifthis

option is enabled, the port will be set to full

duplex. If disabled, it will be set to half duplex.

Full-duplex transmission is enabled by default.

• Link Speed

Set the link speed of the interface

as needed to match the device plugged into the

port. For RJ45 ports, select 1000Mbps, 100Mbps,

or 10Mbps. For SFP+ ports, select 10Gbps or

1000Mbps. SFP ports must be set to 1000Mbps.

- Isolation Select this option to mark this port as an

isolated port. Isolated ports cannot communicate

directly with any other isolated port.

• Apply Click Apply to save changes.

• Cancel Click Cancel to discard changes.

Aggregate

- Aggregate A port channel, also known as a Link

Aggregation Group (LAG), combines multiple links

into a single logical link (single IP address) for load

balancing and/or redundancy. If you select this

option, then this port becomes the start port of the

aggregate link.

• Aggregate Ports Enter the end port number of the

LAG. (Two to four ports are permitted per LAG.)
