Cabletron Systems 7C04-R, 7C03 manual Ethernet Statistics

Using the 7C0x SmartSwitch Hub View

For Ethernet ports, the theoretical maximum load is 10 Mbps; for Fast Ethernet, FDDI, and ATM, it’s 100 Mbps.

•Discard — shows a value for each active port that indicates what percentage of the total packets received at or transmitted by that port were discarded. You can view the discard percentage in three ways:

-In — indicates the number of inbound packets that were discarded, as a percentage of the total load experienced by that port.

-Out — indicates the number of outbound packets that were discarded, as a percentage of the total load experienced by that port.

-Total — indicate the total number of packets that were discarded, as a percentage of total load.

•Errors — shows a value for each active port that indicates what percentage of the total packets received at or transmitted by that port contained an error. You can view the error percentage in three ways:

-In — indicates the number of inbound packets that contained errors, as a percentage of the total load experienced by that port.

-Out — indicates the number of outbound packets that contained errors, as a percentage of the total load experienced by that port.

-Total — indicate the total number of packets that contained errors, as a percentage of total load.

•Nucast (non-unicast) — shows a value for each active port that indicates what percentage of the total packets received at or transmitted by that port were non-unicast (that is, broadcast or multicast) packets. You can view the non-unicast percentage in three ways:

-In — indicates the number of inbound packets that were broadcast or multicast packets, as a percentage of the total load experienced by that port.

-Out — indicates the number of outbound packets that were broadcast or multicast packets, as a percentage of the total load experienced by that port.

-Total — indicate the total number of broadcast and multicast packets, as a percentage of total load.

Ethernet Statistics

For any Ethernet or Fast Ethernet modules installed in your SmartSwitch chassis, you can view a variety of RMON statistics as a percentage of the total load experienced by each port. Note that this option will only be available when at least one Ethernet or Fast Ethernet module is installed in the chassis; when one of these options is selected, the port displays for any installed FDDI or ATM modules will display three dashes (---). Ethernet statistical selections available are:
