Smarts IP reporting interface NotPresent events from Cisco 7206

Issue/Introduction

Symptoms:




Interface NotPresent notifications for some interfaces on Cisco 7206.

Environment

VMware Smart Assurance - SMARTS

Cause

From IP debug discovery logs, the following can be seen from the SNMP trace output while querying the interface admin status :

121: VarBind -> SEQUENCE (0x30), 14 bytes:

123: OBJ-ID (0x06), 10 bytes == ".1.3.6.1.2.1.2.2.1.7.102"

135: Exception (IMPLICIT NULL) (0x81), 0 bytes == <noSuchInstance>

137: VarBind -> SEQUENCE (0x30), 14 bytes:

139: OBJ-ID (0x06), 10 bytes == ".1.3.6.1.2.1.2.2.1.8.102"

151: Exception (IMPLICIT NULL) (0x81), 0 bytes == <noSuchInstance>

Resolution

This is a vendor agent issue. The response above is an invalid agent response, which means that Smarts cannot determine the admin or operating status of an interface, and as a result, reports that the status is NOTPRESENT.
