Ethernet Stats (Ethernet Statistics) | |
|
|
Displays a list of the Ethernet statistics of the LAN port (e1a).
The counters increment in real time and you may enter
Port ± Type of port (e1a).
Initialized Ethernet Ports ± e1a (There is only one other net port on the card). LAN Address ± LAN (or MAC) address of the Ethernet port.
Bytes received ± Number of bytes have been received by the Ethernet port since the last reset.
Bytes transmitted ± Number of bytes have been transmitted by the Ethernet port since the last reset.
Packets received ± Number of packets transmitted by the Ethernet port since the last reset and what type.
±Multicast ± Single packets copied to a specific subset of network addresses.
±Broadcasts ± Messages sent to all network destinations.
±Flooded ± Information received, then sent out to each of the interfaces.
±Filtered ± Processes or devices that screen incoming information.
±Discarded ± Packets discarded.
±VLAN Error ± Number of errors transmitted by the VLAN and what type.
Errors ± Number of errors transmitted by the Ethernet port and what type.
±M =
±L = Late collisions ± collision detected often; at least 64 bytes have been transmitted.
±E = Excessive collisions ± port tried to send a packet 15 times without success.
±Overruns ± No buffer space.
±Bad CRC ± Cyclic Redundancy Check.
±Framing ± Receiver improperly interprets set of bits within frame.
±Jumbo gram ± Ethernet packet too long.
±Overflow ± Part of traffic that is not carried.
±Buffer ± No buffer space.
Fast restarts ± Number of fast restarts and what type (RX off, TX off, Mem err). Endless Pkt ± Number of endless packets received on the Ethernet port. Startless Pkt ± Number of startless packets received on the Ethernet port. Babble ± Number of garbled packets received due to crosstalk.
