The Devices Present link (Network Explorer > Switch Port Management > Devices > Devices Present) is the top-level view in Switch Port Management. It provides the complete list of switches and switch routers that are being managed by NetMRI. The Capacity Summary– Ports pane appears at the top of the table, showing the network totals for Free Ports and Available Ports.

The Devices Present table breaks down this information into each switch's share of network capacity as follows:

  • Action icon: Provides the Action menu with View Device History, Open Telnet Session, Open SSH Session, and Topology Viewer options.

  • Device Name: The configured name of the device.

  • IP Address: The host IP address of the network device (live link to the Device Viewer).

  • Total Ports: The number of switched Ethernet ports, in the selected Device Group, that are being managed by Switch Port Management (if All Devices is chosen, this counter represents all LAN switching ports).

  • Used Trunks: The number of trunk ports used in the switched Ethernet ports.

  • Used Access: The number of access ports used in the switched Ethernet ports.

  • Free Ports: The number of free ports represents the number of network ports that are currently unoccupied and available for immediate use. This include ports that have previously been used but are currently unoccupied, thereby making them available for establishing new connections (hyperlink to Ports Present page).
    NetMRI identifies free ports based on the following conditions:

    • PortStatus = 'Avail'

    • ifOperStatus = ‘down’

  • Available Ports: The number of available ports represents the number of network ports that have remained unused for a duration exceeding the specified time period. These ports are categorized as available because they have not been in use during the specified timeframe. Hence, they can be considered suitable for allocating to other devices or for expanding the network infrastructure (hyperlink to Ports Present page).
    To identify available ports in NetMRI, consider the following conditions:

    • PortStatus = ‘Avail’

    • ifOperStatus = ‘down’

  • Available Ports %: The percentage of all managed switch ports appearing as Available (hyperlink to Ports Present page).

  • PoE Ports: Count of Cisco switched Ethernet ports running the Power over Ethernet switching protocol for IP telephony applications.

Data columns related to interfaces on each device (Free Ports, Available Ports, Available Ports %) provide hyperlinks to the Ports Present table. You can immediately see the operating status and admin status of every port that appears as Free in a given switch.
