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.

If the selected node represents an individual device, the monitor displays data specific to the ports on the device. If the selected node contains multiple devices, the monitor displays data aggregated from all the ports on all the devices.

This topic describes:

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 installed in an SFP, SFP+, or XFP port for information about the port to appear.

Table 1: Port Status Details Table

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 primary or linecard.

Serial Number

The hardware serial number of the device.

Host Name

The hostname of the device.

Description

A text description of the physical interface.

Current Negotiated Speed (Mbps)

The actual operating speed of the port, in megabits per second (Mbps). Depending on the results of autonegotiation, this speed might be less than the maximum speed supported by the port as indicated by port type.

Configured Speed

The speed configured for the port. If the speed is configured to be determined by autonegotiation, the configured speed is shown as Auto.

Duplex Mode

The duplex mode: full (full-duplex), half (half-duplex), or auto (autonegotiation).

Port Type

The port type (for example, 1 Gigabit Ethernet or 10 Gigabit Ethernet interface).

Admin Status

Indicates the administrative state of the port as or .

Operational Status

Indicates the operational status of the port as or .

PoE

Indicates whether the PoE traps are enabled for the port. Possible values are:

  • Enabled—PoE traps are generated for the port

  • Disabled—PoE traps are not generated for the port

  • N/A—PoE traps are not applicable for the port

Last Flap Time

Date and time at which the advertised link became unavailable, and then, available again.
