[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 ipNetToPhysicalPhysAddress
"ipNetToPhysicalPhysAddress" can retrieve both IPv4 and IPv6 addresses, you also can use "ipNetToMediaPhysAddress" for IPv4 only. The real return message is:
IP-MIB::ipNetToPhysicalPhysAddress.9.192.168.1.1 = STRING: 0:6:f6:bf:8b:cc
IP-MIB::ipNetToPhysicalPhysAddress.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::ipNetToPhysicalPhysAddress\.\d+.*
The "MAC Detector" will use the "result format" to get every record and retrieve the mac and ip information.
[edit] 3.2 Test
You may click "test" to test the SNMP commands in the list.
