Products

• VMware Smart Assurance

Issue/Introduction

Symptoms:




There are number of Perl related errors that can appear with Network Protocol Manager for probes of BGP v3 and OSPF v3.  These protocols do not support SNMP and must be done via CLI which uses a Perl script to connect via SSH.

Some of the examples of error messages that can be seen are:

Environment

VMware Smart Assurance - SMARTS

Cause

While the error messages are somewhat vague, they all reference an inability to access the device in question using SSH v2.  Either the device is not responding to SSH at all or will not negotiate with SSH v2.  These error indicate a problem that should be corrected on the device to make sure that SSH v2 connections can be made.

Resolution

Verify SSH v2 connectivity and support on the device.  If this information is not readily available, consult the vendor of the specific device.
