Issue/Introduction

Interface NotPresent notifications for some interfaces on Cisco 7206.

Environment

10.x

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.
