[edit] 1 MAC Detector

"MAC Detector" can gather client's physical MAC addresses via SNMP protocol. With "MAC Detector" enabled, you can:

  • Set access policy by MAC addresses.
  • Set IP-MAC binding in a multiple-segments network.
  • Show real MAC addresses in "Real-time Bandwidth".
  • Show real MAC addresses in "Internet Usage".

[edit] 2 Settings

[edit] 3 SNMP Commands

"MAC Detector" use snmpwalk commands to send SNMP query to manageable devices. Usually, the snmpwalk commands are sent to routing devices, for example: core three-layer switch, or manageable wireless AP.

  • "SNMP Commands": snmpwalk commands be sent to the manageable devices. Multiple commands are supported.
  • "Result Format": a regular expression which matches ONE record row.

[edit] 3.1 Example

Suppose the core three layer switch has ip address "192.168.1.2", the "SNMP Command" is:

snmpwalk -v 2c -c public 192.168.1.2 ipNetToMediaPhysAddress


The real return message is:

IP-MIB::ipNetToMediaPhysAddress.9.192.168.1.1 = STRING: 0:6:f6:bf:8b:cc

IP-MIB::ipNetToMediaPhysAddress.9.192.168.1.11 = STRING: ae:15:53:a0:9b:7f ...


To match every return rows, we configure the "result format" as:

IP-MIB::ipNetToMediaPhysAddress\.\d+.*


The "MAC Detector" will use the "result format" to get every record and retrieve the mac and ip information.
