Snmpcollector probe engine id limit

Products

Issue/Introduction

Tried adding a profile for a device(snmpv3) in the snmpcollector probe but it kept failing. The error in the log mentioned the device engine id was too long. May I know what is the limit for the engine id of a device for the snmp collector probe? Are we able to tweak that limit to allow that device to be added?

Environment

UIM: Any supported UIM version

probe: snmpcollector

Resolution

 The snmpcollector probe follows the SNMPv3 RFC. Ensure the engine ID is configured on the device to meet the standards in the RFC 

SNMP Engine IDs are composed of a series of octets (bytes).
They must be at least 5 octets in length and may not be more than 32 octets long.
Each octet can contain a value from 0 up to 255. Hexadecimal: ‘00’H up to ‘FF’H
