Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is DGS-1248T-B1-MIB?

DGS-1248T-B1-MIB is a D-Link vendor MIB for the DGS-1248T 48-port Gigabit smart switch (B1 hardware revision), part of D-Link's Gigabit smart switch line, covering switching, VLAN, and port management functionality. It exposes port-level configuration and status, VLAN membership, and general switching feature settings for this higher-port-density smart switch. For monitoring it would be used to track hardware/software status including per-port link state across all 48 ports, VLAN assignment correctness, and overall switch system health (uptime, configuration), important given the larger number of connected end devices such a switch typically serves. It is a proprietary enterprise MIB built on standard MIB-II interface and system groups, consistent with D-Link's smart-switch MIB pattern. It is deployed on DGS-1248T-B1 switches in SMB wiring closets or access-layer deployments needing higher port density than the 16-port model. Engineers can download the DGS-1248T-B1-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DGS-1248T-B1-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.

Monitoring Examples

An admin managing a 48-port access switch would poll per-port link/operational status across all ports to quickly spot any port that has gone down, which with 48 connected devices could indicate anything from a single failed cable to a wider closet power/network issue. VLAN membership objects would be checked to confirm ports are still assigned to their intended VLANs, especially after a configuration change. System uptime and configuration/version objects typical of this switch family would be polled to confirm stability and detect unexpected reboots.

The purpose of this timer is to avoid multiple report messages for the same group being forwarded out. So that unnecessary multicast packets in the network can be avoided. The 'ReportForwardTimer' is per multicast group. This timer is started as soon as a report message for that group is forwarded out. Within this 'ReportForwardInterval' if another report for the same group arrives, that report will not be forwarded. The first report message which is received for this group after the 'ReportForwardInterval' only will be forwarded out. When set as '0' , this timer will not be started and all the report messages will be forwarded as and when they are received.

A timer is started by a bridge with a time interval equal to IgsLeaveProcessInterval. If a report message is received before above timer expires, Leave message is dropped.Otherwise Leave message is either forwarded on all ports of the bridge or only on router port depending upon the case.

INT igsSharedSegmentAggregationInterval	1.3.6.1.4.1.171.10.76.6.22.1.9	INTEGER	read-only	This is the interval (in seconds) for which reports of IGMPv3 messages on a shared segment will be aggregated for a group. This timer will be started only when multiple hosts are identified on a port for the Multicast group. The timer will be stopped when all but one host is left on the port for the Multicast group. This timer will be re-started on its expiry and Multicast forwarding table will be updated.
INT igsGblReportFwdOnAllPorts	1.3.6.1.4.1.171.10.76.6.22.1.10	INTEGER	read-only	IGMP snooping module will forward reports only on router ports by default, to enable forwarding on all other ports the object must be set to allports.

INT igsLastMembQueryInterval	1.3.6.1.4.1.171.10.76.6.22.1.17	INTEGER	read-write	The Last Member Query Interval is the Max Response Time inserted into Group-Specific Queries sent in response to Leave Group messages, and is also the amount of time between Group-Specific Query messages. This value may be tuned to modify the leave latency of the network. A reduced value results in reduced time to detect the loss of the last member of a group.
