The following page sections are typical for all active QoS configurations.
Add / Change / Delete Group
Use the controls provided at the top and far right of this section to create / add new QoS
configuration groups. The remainder of this section displays previously created groups,
numbered in the order of creation.
The individual columns are defined as follows:
•
Index – The automatically ‐ assigned internal index number for the group is identified here.
•
Name – This is the name assigned to the group. It must be unique across all groups.
•
CIR (kbps) – This is the Committed Information Rate for the QoS Group. The QoS Manager
will try to guarantee this date rate for all traffic that matches this group.
•
MIR (kbps) – This is the Maximum Information Rate for the QoS Group. The QoS Manager
will not allow traffic that matches this Group to send more than this data rate.
•
Max MODCOD –This is the modulation code assigned to the group. There can be a
maximum of six different MODCODs enabled at the same time. At the least , all traffic that
matches this group is sent on this MODCOD. At best , the QoS Scheduler opportunistically
puts these packets into a lower MODCOD in order to optimize utilization of the WAN
bandwidth.
•
Mode – When adding a new group or modifying an existing group, use the drop ‐ down menu
to select QoS operation as Off , DiffServ (Differentiated Services), Max/Pri (Maximum/
Priority), or Min/Max (Minimum/Maximum).
Note the following:
o
Off – This mode disables QoS. Instead of an operable page, the ‘Configuration | WAN |
QoS’ page appears as shown in the top example in Figure 5 ‐ 15 .
o
DiffServ –This mode allows the CDM ‐ 800 to operate in Differentiated Services (DiffServ)
Mode to make it fully compliant to the Differentiated Services QoS RFC (Request For
