DiffServ Rule DSR= 48 bytes,
numerical
Command or Query.
Note: To set DSR, the system has to be set in DiffServ mode by issuing
<1/QSM=3.
The value in this is broken into separate values:
Read/Get Format:
cccc|ddd ddd|mmmmm|MMMMM|p where:
cccc = DiffServ class name
ddd ddd = DiffServ Code Point. The code point has 0, 1, X
mmmmm = Minimum bandwidth in kbps (range = 0..99999 kbps)
MMMMM = Maximum bandwidth in kbps (range = 0..99999 kbps)
p = priority is fixed and assigned by system.
User is allowed to modify Assured Class Rules 9, 10, 11, 12 ONLY, while
the QoS [QSM=3] is in DiffServ mode.
Write/Set Format
Example: DSR[9]=00100|00400
Sets min bw to 100, max bw to 400.
DSR=
DSR!
DSR? DSR =x [1..48]
(m = Min value, M = Max
value)

Table
Query only.
Displays the complete diffserv rules. Can be issued when QoS mode is set
in Diff Serv. There are 12-rows/rules. Each rule is separated by chr(13).
