Enterasys Networks FN 100 manual Address, Non-Unicast, Discarded, Error

The FN100 Chassis View

You can also access this information via the I/F Statistics option available on the

TIP individual port menus.

Three informational fields appear in the upper portion of the window:

Description

Displays the interface description for the currently selected interface: Ethernet or Fast Ethernet.

Address

Displays the MAC (physical) address of the selected interface.

Type

Displays the interface type of the selected port: ethernet-csmacd.

The lower portion of the window provides the following transmit and receive statistics; note that the first four statistics are also graphically displayed in the pie charts.

Unicast

Displays the number of packets transmitted to or received from this interface that had a single, unique destination address. These statistics are displayed in the pie chart, color-coded green.

Non-Unicast

Displays the number of packets transmitted to or received from this interface that had a destination address that is recognized by more than one device on the network segment. The multicast field includes a count of broadcast packets — those that are recognized by all devices on a segment. These statistics are displayed in the pie chart, color-coded dark blue.

Discarded

Displays the number of packets which were discarded even though they contained no errors that would prevent transmission. Good packets are typically discarded to free up buffer space when the network becomes very busy; if this is occurring routinely, it usually means that network traffic is overwhelming the device. To solve this problem, you may need to re-configure your bridging parameters, or perhaps re-configure your network to add additional bridges or switches. These statistics are displayed in the pie chart, color-coded magenta.

Error

Displays the number of packets received or transmitted that contained errors. These statistics are displayed in the pie chart, color-coded red.
