Frame Size Analysis—A series of counters that rep- resent the composition of the traffic on the Switch 2000 TR. The counters display the percentage of packets that are categorized by received length as represented by the following octet parameters:

■18 to 63 octets

■64 to 127 octets

■128 to 255 octets

■256 to 511 octets

■512 to 1023 octets

■1024 to 2047 octets

■2048 to 4095 octets

■Packets greater than 4095 octets
