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
