Issue/Introduction

The Alias field in Performance Management is shorter than what is shown on the device via it's configuration.

The Description field in Performance Management is shorter than what is shown on the device via it's configuration.

Truncated ifAlias alias and/or ifDescr description values for items in Performance Management.

Environment

Performance Management, all supported versions

Cause

The MIB OIDs where Performance Management looks for the values are truncated. Performance Management is displaying the same value the device MIB is providing.

Resolution

If the device MIB is reporting values that do not match it's configuration, the device administrator or device vendor support may be able to help determine a cause and solution for the problem.

The problem values can be checked in the MIB data Performance Management queries using the following commands.

  1. To query the ifAlias value run:
    • snmpwalk -v 2c -c <communityString> <ipAddress> 1.3.6.1.2.1.31.1.1.1.18
  2. To query the ifDescr value run:
    • snmpwalk -v 2c -c <communityString> <ipAddress> 1.3.6.1.2.1.2.2.1.2

Additional Information

Interface Alias Names could be set in PM to override the bad values from the device as a workaround.
