Using the 7C0x SmartSwitch Hub View
•Load — shows a value for each active port that represents that port’s traffic as a percentage of the theoretical maximum load: either 10 Mbps (for Ethernet), or 100 Mbps (for Fast Ethernet).
•Packets — displays the number of good packets experienced by each interface in one of four ways:
-Packets/second — the rate of traffic being experienced by the port
-Average Packet Size — displayed in bytes; calculated by dividing the total number of octets by the total number of good packets
-Broadcast — the percentage of good packets on each port that are broadcast packets
-Multicast — the percentage of good packets on each port that are multicast packets
•Collisions — displays the total number of receive (those the device detects while receiving a transmission) and transmit (those the device detects while transmitting) collisions, as a percentage of the total traffic experienced by the port.
•Errors — displays the total number of packets with a specific error type, as a percentage of the total number of errors experienced by the port. Available error types are:
-CRC/Alignment — the number of packets processed by a port that had a
-Fragments — the number of packets processed by a port that were undersized (less than 64 bytes in length; a runt packet) and had either a
-Jabbers — the number of packets processed by a port that were oversized (greater than 1518 bytes; a giant packet) and had either a
•Frame Sizes — displays the total number of packets processed by a port that were of a specific size, expressed as a percentage of the total number of good packets experienced by the port. Frame size breakdowns available are:
-Runts (packets with fewer than 64 bytes)
-64
-65-127
-128-255
-256-511
