Enterasys Networks 6000 - Manual (Page 50)

Viewing Device Information 2-31
The Device View
Three informational fields appear in the upper portion of the window:
Description
Displays the interface description for the currently selected interface (e.g., Enterasys Enet
Port, Enterasys Fast Enet Port, FDDI, ATM, or Enterasys Backplane Port).
Address
Displays the MAC (physical) address of the selected interface.
Type
Displays the interface type of the selected port: ethernet-csmacd, fddi, or atm.
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. Consult the Enterasys Network Troubleshooting
Guide for more information.
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.
TIP
You can also access this information via the I/F Statistics option available on the
individual port menus.
