CTRON-DHCP-MIB.mib object view, vendor Enterasys-Networks-Inc

Introduction

Most network devices and programs ship with so-called MIB files to describe the parameters and meanings (i.e.: friendly names) which are available for monitoring via SNMP.
ActiveXperts Network Monitor 2024 can import vendor-specific MIB files, so it can be used to monitor specific OID's (Object Identifiers). This way, you can monitor your devices, computers, etc. by selecting your relevant OID's by name.

ActiveXperts Network Monitor 2024 can import MIB file CTRON-DHCP-MIB and use it to monitor vendor specific OID's.
