Question:

How does PM classify a device as a Router, Switch, Router-Switch or other device types?

Environment:
Any CAPM environment
Answer:

How does PM classify a device as a Router, Switch, Router-Switch or other device types?

  • Here is the information on how we classify a device as a Router or Switch based on the value of the sysServices and ipForwarding attributes.

 

For SNMP device, we use ipForwarding and sysServices to determine device type

  • ipForwarding (1.3.6.1.2.1.4.1) – Flag to indicate if acting as IP gateway
  • sysServices (1.3.6.1.2.1.1.7) – A set of services that a device may offer

 

Convert sysServices INT value to binary:

  1. Repeater:           bit 1 is set (not supported by PM)
  2. Switch:               bit 2 is set
  3. Router:               bit 3 & ipForwarding are set
  4. Switch-Router: bit 2, 3 and ipForwarding are set
  5. Server:               none of above and bit 4 or 7 is set

Example:  ipForwarding = 1,  sysServices = 6 -> Binary 1 1 0  - this classifies as a Switch-Router
