Description: D-Link 3100 embedded web MIB providing objects to configure and monitor the device's built-in HTTP/HTTPS management interface.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is DLINK-3100-EMBWEB-MIB?

DLINK-3100-EMBWEB-MIB is a D-Link vendor MIB (using RADLAN-derived naming, 'rlEmWeb') that configures and monitors the embedded HTTP/HTTPS web management server built into D-Link 3100-series devices. It exposes configuration data for the web server's security model: per-user access-control entries with username, password, access level, allowed source IP, port, and SNMP version binding, plus a global connection close-timeout setting. Its relevance to device status is management-plane availability and security posture rather than traffic hardware health -- confirming the embedded web server is configured with the intended access restrictions and detecting unauthorized or overly permissive entries in the security table. It depends on the device's core management/authentication infrastructure and the RADLAN embedded-web-server codebase shared across multiple OEM switch vendors. It is deployed on D-Link 3100-series managed switches that offer web-based device administration. Engineers can download the DLINK-3100-EMBWEB-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DLINK-3100-EMBWEB-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

D-Link 3100-series managed switch

Monitoring Examples

An operator would walk rlEmWebSecurityTable/rlEmWebSecurityEntry to review each rlEmWebSecurityUserName's rlEmWebSecurityAccess level, rlEmWebSecurityIpAddr restriction, and rlEmWebSecurityStatus (enabled/disabled), flagging any entry with unrestricted IP access at an administrative access level as a security risk. rlEmWebCloseTimeout would be checked to confirm idle web-management sessions are being closed within policy, and rlEmWebMibVersion identifies which version of the embedded web feature set the device firmware supports.

What Can Be Monitored

web management user accounts and access level
IP/port access restrictions for web management
web security entry status
session close timeout
