Protocols

Select the PROTOCOLS button in the Bottom Area. The protocols screen

shows the number of packets and percentage of the total captured data for

each protocol. A protocol is added to the protocol list as it is detected. The

protocols at the Ethernet Frame level (i.e. RFC894, IEEE 802.2/3, LLC,

LCC+Snap, VLAN, etc.) and Ethernet type level (i.e. ARP, IP, IPX,

AppleTalk, NetBIOS, IPv6, etc) are displayed first when detected. It shows

how many frames received in KB and the percentage of a given protocol in

relation to the total number of protocols received.

An outlined white box to the left of the protocol’s name means there are

more protocols to be displayed under that Ethernet type. The box will be

filled in and shows the rest of the protocols under that type. The

LANEXPERT provides protocol names for standard protocols such as

LLC, ARP and NETBIOS. Unknown protocols are indicated by the word

TYPE with the transmitting port number. Port numbers in hexadecimal

format are indicated by an “h“ following the number.

If there are too many protocols to display on one screen, press the Down

arrow on the right of the screen to scroll to the rest of the protocols. The

LANEXPERT can display up to 31 different protocols. After 31 protocols

are detected, all additional new protocols are counted together in the 32

slot under OTHERS.
