The Component Inventory page (Device Viewer –> Device/Network Explorer –> Component Inventory) lists all hardware information for the device, if SNMP data is available. Specific data depends on the vendor platform, and may include hardware revision, firmware revision, model number and serial number. The page lists all installed interfaces and the chassis for the device. The chassis listing also provides the network device’s serial number and model number. Additional information can be displayed using the Columns option available via column header menus.

Viewing Open Services on a Device

The Open Services page (Device Viewer –> Device/Network Explorer –> Open Services) lists all TCP and UDP ports that are currently open on the device. This feature not only gives you a picture of what the selected device is doing – it can also give you a quick view of possible security holes in the device’s basic configuration. Based on the device type, NetMRI will expect certain services to be configured on the device, and those values will appear in the Expected Service column as the protocol name. Devices will often show services such as telnet, BootP, or SNMP as a service. Services that are detected as being actively used on the device appear in the Verified Service column.

Any QoS queue that is dropping packets is identified. The relative priority of the queue determines the severity level of the issue that is generated in the Issue List. The table below shows the severity generated for each queue's Per-Hop Behavior (PHB) and DSCP value that are commonly associated with applications. Drops in high priority queues will generate Error issues, while medium priority queues generate Warning issues. The lowest priority queues, including the scavenger queue, generate Info issues.
