Tos Field Matching - Netopia 3341-ENT Firmware User Manual

In addition, the TOS field has been added to the classifier list in a filter. This allows you to filter on TOS field
settings in the IP packet, if you desire.
The new filterset screen appears as follows:
Enabled:
Forward:
Call Placement/Idle Reset:
Force Routing:
Gateway IP Address:
Source IP Address:
Source IP Address Mask:
Dest. IP Address:
Dest. IP Address Mask:
TOS:
TOS Mask:
Protocol Type:
Source Port Compare...
Source Port ID:
Dest. Port Compare...
Dest. Port ID:
Return/Enter to set comparison of packet Port ID and Filter Port ID.
Enter the packet specific information for this filter.
To use the policy-based routing feature, you create a filter that forwards the traffic.
•
Toggle Forward to Yes. This will display the Force Routing options.
•
The Call Placement/Idle Reset setting is used to determine if a packet which matches the filter will cause
an "instant-on" link to connect, if it is down; or reset its idle timer, if it is already up.
If you select No Change from the Call Placement/Idle Reset pull-down-menu, a match on this rule will
keep the WAN connection alive by resetting the idle-timeout status.
If you select Disabled, a match on this rule will not reset the idle-timeout status.
For example, if you wanted ping traffic not to keep the link up, you would create a filter which forwards a
ping, but with the Call Placement/Idle Reset set to Disabled.
• Toggle Force Routing to Yes.
• Enter the Gateway IP Address in standard dotted-quad notation to which the traffic should be forwarded.
•
You can enter Source and Destination IP Address(es) and Mask(s), Protocol Type, and Source and
Destination Port ID(s) for the filter, if desired.
TOS field matching
Netopia Firmware Version 8.7 supports two additional parameters in an IP filter: TOS and TOS Mask. Both
fields accept values in the range 0 – 255.
