Configuring SPAN / RSPAN Sources
If you have selected Create to start a new SPAN session on the Setup>Data Sources>SPAN dialog
window, follow these steps:
• Select the SPAN type and other parameters to configure the SPAN session and select Submit when
finished. The traffic selected for the SPAN session is now being forwarded to the NAM-1/2 for
monitoring. Remember, no monitoring takes place until the data sources have been enabled for
monitoring. Before enabling the monitoring, let’s first look at the configuration process for the other
types of data sources.
• Before RSPAN data sources will be displayed when selecting the RSPAN radio button, the user must
first configure the source switch with an RSPAN VLAN and the source ports, and also configure the
NAM host switch with the RSPAN VLAN number.
• When the host switch is running Cisco IOS software, the SPAN session dialog box includes a pull
down menu to set the monitor session number. When using CatOS, the session id is automatically
selected and tracked.
