D-Link DSL-2542B User Manual

User Define

On this window, you can assign a Weight, on a percentage basis, to each

of the four priority queues. In addition, you can specify the number of

bytes from the beginning of a given packet’s IP header to set a pointer.

From this pointer, you can then specify a Value (in hexadecimal) and a

Mask (in hexadecimal) for the Router to match when examining packets

crossing the specified priority queue. It is recommended that you not enter

a QoS scheme of this type unless you fully understand Offsets, pointers,

masks, and IP headers or you are instructed to do so by your ISP. When

you are finished, click Apply Settings and then click the Reboot button to

let your new settings take effect.

Here’s an example of some typical User Defined IP QoS values:

Packet Value Mask IP Header Offset

IGMP 0x02 0xff 9

FTP 0x0015 0xffff 22 (destination port)

IP Source 192.168.1.1 0xc0a80101 0xffffffff 12

1 2 ... 30 31 32 33 34 35 36 37 38 39 40 ... 58 59
