Micetro has the capability to scan a defined list of routers and retrieve the ARP tables and/or the subnets and their information found on the routers.
To perform this scanning, the following suite of SNMP OIDs are used:
- ipNetToMediaPhysAddress: .1.3.6.1.2.1.4.22.1.2
- ipAdEntAddr: .1.3.6.1.2.1.4.20.1.1
- ipAdEntIfIndex: .1.3.6.1.2.1.4.20.1.2
- ipAdEntNetMask: .1.3.6.1.2.1.4.20.1.3
- entPhysicalSerialNum: .1.3.6.1.2.1.47.1.1.1.1.11
- sysName: .1.3.6.1.2.1.1.5
- cviRoutedVlanIfIndex: .1.3.6.1.4.1.9.9.128.1.1.1.1.3
- cvVrfInterfaceType: .1.3.6.1.4.1.9.9.711.1.2.1.1.2
- cvVrfName: .1.3.6.1.4.1.9.9.711.1.1.1.1.2
Note
Each device is only queried once, as the system checks the serial number and the sysName to discover both physical and virtual switches.
