To View the Switch Details
The details of the switch and port to which a device is connected is shown under the Switch Details column under the Discovered tab. The switch details could have three different values:
Switch IP, Switch Name, ifIndex, port, and ifName details - This refers to the actual details where a particular device is connected.
Learned in xyz, but not directly connected - This refers to the switches through which the device has communicated and are not connected directly to these switches.
Unknown - The switch details are not known. This can happen when you have not mapped all your switches using the Switch Port Mapper tool or the device is detected after scanning your switches. Mapping your switches again will show the details here.
To Block/Unblock a Switch Port
Select a rogue device for which you need to restrict the access by blocking the port and click Block/Unblock Switch Port. This opens the Block/Unblock Switch Port dialog with the details of the device and switch details.
Specify the SNMP Write Community of the switch and click Block Port.
When you block a switch port, the admin status of the port is set to "Down"
To unblock a blocked port, specify the Switch Name/IP Address, ifIndex, SNMP Write Community and click Unblock Port. This will set the "admin status" of the port to "Up"
