A. Yes. The variables are found in RFC1315 and the Frame Relay data terminal ready (DTR) management information base. The SNMP variable for a circuit’s status is fr CircuitState. Its Abstract Syntax Notation One (ASN.1) object identifier (OID) form is 1.3.6.1.2.1.10.32.2.1.3. It resides in the frCircuitTable. To get the value (the status in this case), the index and the DLCI would be the first and second instance respectively. By issuing the SNMP Get or Getnext commands, you can find out the system’s internal circuit status. The following table lists valid values: Value State 1 invalid 2 active 3 inactive For Cisco, you would see either 2 or 3.
