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.

This field will instruct the Switch to mask the packet header beginning with the offset value specified:

value (0-15)- Enter a value in hex form to mask the packet from the beginning of the packet to the 15th byte.

value (16-31)– Enter a value in hex form to mask the packet from byte 16 to byte 31.

value (32-47)– Enter a value in hex form to mask the packet from byte 32 to byte 47.

value (48-63)– Enter a value in hex form to mask the packet from byte 48 to byte 63.

value (64-79)– Enter a value in hex form to mask the packet from byte 64 to byte 79.

The user may set the Access Profile Table on a per-port basis by entering an entry in this field. Entering all will denote all ports on the Switch. The port list is specified by listing the lowest switch number and the beginning port number on that switch, separated by a colon. Then the highest switch number, and the highest port number of the range (also separated by a colon) are specified. The beginning and end of the port list range are separated by a dash. For example, 1:3 specifies switch number 1, port 3. 2:4 specifies switch number 2, port 4. 1:3 - 2:4 specifies all of the ports between switch 1, port 3 and switch 2, port 4 − in numerical order.
