Issue/Introduction

IF Alias description is getting truncated in tools and affecting bad link detection for CISCO devices. Does it have any character limitation .

Is there any way to rediscover the interface description soon as modified at device end

Environment

Release : Any

Component : Spectrum Discovery and Modeling

Cause

The definition of ifAlias in the ifXTable in the ifMIB dictates how many characters can be stored in the ifAlias attribute.

According to the definition of the ifAlias attribute, the maximum size for an ifAlias is 64 characters:

ifAlias OBJECT-TYPE
 SYNTAX DisplayString (SIZE (0 .. 64))
 ACCESS read-write
 STATUS current 

Resolution

There is no way to increase the number of characters for ifAlias as this is dictated in the ifMIB.

This is functioning as designed.
