Verax NMS Generic Switch management plugin allows easy monitoring, alerting, health check, management and performance reporting of SNMP-enabled switches supporting the following MIBs:
The Generic Switch plugin can communicate using SNMP v1, v2 or v3.
The Generic Switch plugin enables monitoring and management of switch types/models that do not have dedicated Verax NMS plugins. Dedicated plugins come first in the discovery order: if a dedicated plugin exists it is preferred over a generic one. While the dedicated plugins typically provide additional functionality (display more information, allow for execution of management actions, configuration management, etc.), the Generic Switch plugin provides full capability in terms of monitoring, performance measurements and alerting. Examples of dedicated switch plugins include:
Please refer to the Verax NMS & APM page for more information on specific device support.
The view presents general configuration information about a switch such as:
The view displays current IP configuration parameters (such as forwarding, default TTL, reassembly timeout and others) and statistics (input receives, forwarded datagrams, routing discards and others).
The view provides an inventory of all network interfaces on a device including:
This view provides a list of all IP addresses configured on a device including: address, mask, interface and broadcast address.
The view displays current IP routing table on a device including:
This information is displayed only if a managed switch has routing functionality.
The view provides detailed information about hardware (entities) on a device including:
This information is only displayed if the device supports the SNMP ENTITY-MIB.
The Generic Switch supports the standard MIB-2, enabling NMS to define sensors, performance counters, alarms and traps based on standard MIB definitions.
Additional MIBs can be loaded via NMS MIB Browser. OIDs from these MIBs can be used to define additional sensors and performance counters as needed.
The plugin provides predefined templates for most commonly monitored switch items (listed in the table below). Other, user-defined sensors and performance counters can be added.
