Note: Later versions of the Windows OS may not honor this ICMP message for any
except the very largest fragment size. If this occurs, then many Web operations may
not work if a voice call is in progress.
IP Fragmentation Size
Click this drop-down menu to select the size (bytes) that the packets will be
fragmented into. The available numbers consider ATM cell size boundaries, ATM
Ethernet encapsulation, IP headers, and PPPoE encapsulation: 100, 148, 244, 292,
340, 388, or 436 bytes.
Class of Service
Displays the supported classes of service (ordered from lowest priority to highest
priority).
•
Network Control (NC)
•
Expedited Forwarding (EF)
•
Assured Forwarding (AF4)
•
Assured Forwarding (AF3)
•
Assured Forwarding (AF2)
•
Assured Forwarding (AF1)
•
Best Effort (BE)
Peak Info Rate
Displays the maximum allowed rate for this Class of Service, expressed as a
percentage of the WAN rate. Packets will be discarded if the offered rate exceeds this
value. The Peak Information Rate can be used to prevent higher priority traffic from
using all available bandwidth. No limit is necessary for the lowest priority traffic
(BE). No limit is necessary for the lowest priority traffic (BE). A value of zero causes
the modem to drop all packets for this class of service.
Committed Info Rate
Displays the committed rate (for Assured Forwarding classes), expressed as a
percentage of the WAN rate. Packets may have the drop priority of the DSCP
increased if the offered rate exceeds this value. Note that this only occurs for non-
zero committed rates (i.e., a value of zero turns off the committed filter).
Enable QOS Filter Rules
Click this check box to enable or disable Enable QOS Filter Rules, allowing
remarking of the packet DiffServ CodePoint (DSCP). Various filtering (matching)
options can be set to determine which packets should be re-marked. Changing the
DSCP of a packet changes its priority for transmission. QOS Services does not have
to be enabled for filter rules to be activated. By default,
Enable QOS Filter Rules
is
enabled (checked).
Edit QOS Filter Rules
Click this button to edit QOS Filter Rules using the
QoS Filters
screen. Refer to
section 13.4.5.1, “QoS Filters—Edit Filter Rules.”

Interface and Direction
Click this drop-down menu to determine where the rule will be applied. Normally,
all of the local ports (Ethernet and USB) are connected to bridge 0. Port mapping
can be used to move ports to a different bridge.

routed.

is routed.
•
To Private LAN: Applied to packets headed toward the Private LAN, after
the packet is routed.
