Concept Guide

This section displays source and destination ports configured for port mirroring and transmission

direction. From this section, you can configure port mirroring settings.

Configuring Port Mirroring Settings

You can configure port mirroring settings in the Port Mirroring section of the Switching Layer-2 page.

Port mirroring forwards frames to a monitoring port.

1. From the navigation menu, click Switching Layer-2.

The Switching Layer-2 page appears.

2. In the Port Mirroring section, click View Details.

The Port Mirroring dialog box appears.

3. To create a port mirroring session to monitor, click Add.

4. In the Select Source (Internal Ports) section, select the ports on the I/O Aggregator device whose

traffic you want to copy. You can select a maximum of four.

5. From the Select Destination (External Port), select the monitoring port.

6. In the Direction area, select the type of traffic you want copied:

• Rx — Receiving

• Tx — Transmitting

• Rx and Tx — Both receiving and transmitting

7. Click Apply.

To edit the monitoring ports in a session, select the check box of the session and click Edit. You can only

edit the source ports. To delete a session, select the check box of the session and click Delete.

Fibre Channel

The Fibre Channel section of the Switching Layer-2 page displays options for Fibre Channel mode for

I/O Aggregator devices

This page displays settings depending on the selected Fibre Channel mode.

Table 1. Fibre Channel Modes

Mode Description

FIP Snooping Bridge (FCoE) FIP Snooping Bridge when enabled monitors FCoE

Initiation Protocol (FIP) logins, solicitations, and

advertisements. In this monitoring or snooping

process, the switch gathers information about

ENode and FCF addresses. With this information,

the switch places filters that only allow access to

ENode devices that successfully log in. The FCoE

VLAN can then deny all other traffic except this

loss-less FCoE storage traffic

NPIV Proxy Gateway In Fibre Channel networks, FC switches are trusted

devices that act as a Fibre Channel Forwarder

(FCF). Other devices must log in to these switches

before they can communicate with the rest of the

fabric. FC connections usually are point-to-point

allowing the FC switches complete control over

the traffic that connected devices insert into the
