Men & Mice 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:

 

IP-MIB:

  • 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

ENTITY-MIB:

  • entPhysicalSerialNum: .1.3.6.1.2.1.47.1.1.1.1.11

SNMPv2-MIB:

  • sysName: .1.3.6.1.2.1.1.5

CISCO-VLAN-IFTABLE-RELATIONSHIP-MIB:

  • cviRoutedVlanIfIndex: .1.3.6.1.4.1.9.9.128.1.1.1.1.3

CISCO-VRF-MIB:

  • 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

 

Each device is only queried once, as the system checks the serial number and does not synchronize with the same serial number twice.
