Port Status Monitor
The Port Status monitor provides summary and detailed information about the status of the physical network interfaces for the selected node in the View pane.
This monitor is available in the Equipment tab of Monitor mode when you select an EX Series switch or Virtual Chassis member in any view. For individual devices, it displays port information specific to the device. However on the Summary tab, it displays aggregated data from all switches and Virtual Chassis in the network.

Port Status Summary
The summary view of the Port Status monitor displays two pie charts:
- Admin Status–Of the interfaces on the selected node, shows the proportion of interfaces that are administratively enabled and that are administratively disabled.
- Free vs Used–Of the network interfaces that are administratively enabled, shows the proportion of interfaces that are in use (operationally up) and that are not in use (operationally down).
Mouse over a pie segment to view the actual number of ports. Click the details icon to open the Port Status Details window.
Port Status Details
The Port Status Details table provides details about the physical network interfaces for the selected node, as shown in Table 1.
 | Note: You must have a transceiver plugged into an SFP, SFP+, or XFP port for information about the port to appear. |
Table 1: Port Status Details
Field | Description |
|---|---|
Port Name | The name of the physical interface. |
MAC Address | For standalone EX Series switches, the first five groups of hexadecimal digits are determined when the switch is manufactured. The switch then assigns a unique MAC address to each interface by assigning a unique identifier as the last group of hexadecimal digits. For Virtual Chassis members, the first four groups of hexadecimal digits are determined when the switch is manufactured. The fifth group of hexadecimal digits reflects the role of the member in the chassis, such as master or line card. |
Serial Number | The hardware serial number of the device. |
Host Name | The hostname of the device. |
Description | A text description of the physical interface. |
Speed (Mbps) | The speed of the port, in megabits per second (Mbps). |
Duplex Mode | The duplex mode: full (full-duplex), half (half-duplex), or auto (autonegotiation). |
Port Type | For EX Series switches, the port type can be 1 Gigabit Ethernet or 10 Gigabit Ethernet interface. |
Admin Status | The administrative state of the port: enabled (up) or disabled (down). |
Operational Status | The operational status: link up or link down. |
Last Flap Time | Date and time at which the advertised link became unavailable, and then, available again. |
