will change the menu according to the requirements for the type of profile.
• Select Ethernet to instruct the Switch to examine the layer 2 part of each packet
header.
• Select IP to instruct the Switch to examine the IP address in each frame's header.
• Select Packet Content Mask to specify a mask to hide the content of the packet
header.
• Select IPv6 to instruct the Switch to examine the IPv6 part of each packet header.
Offset
The offset field is used to examine the packet header which is divided up into four “chunks” where
each chunk represents 4 bytes. Values within the packet header chunk to be identified are to be
marked in hexadecimal form in the “mask” field. The following table will help you identify the bytes
in the respective chunks.
