The Advanced Connection Options screen appears.
The Router will recognize a delay-sensitive packet as having the low-latency bit set in the TOS field of the IP
header.
If you toggle Prioritize Delay-Sensitive Data to Yes the router will place these packets at the front of the
transmission queue to the WAN link, overtaking non-delay-sensitive traffic. Accepting the default No will allow
the normal sequential queue of data packets.
VRRP Options (WAN Link Failure Detection)
Beginning with Software Version 8.5.1, the software offers VRRP Options to detect Layer 3 link failures on the
WAN. When you enable this feature, the Motorola Netopia
®
Router will continuously Ping one or two hosts that
you specify to determine when a link fails, even if the physical connection remains established. If Layer 3 WAN
Link Failure Detection is enabled, the Motorola Netopia
®
Router will send continuous Pings, so the WAN link will
stay up and idle timeout will not occur.
See “Virtual Router Redundancy (VRRP)” on page 7-34 for a detailed description of VRRP and how to create
Virtual Routers.
To enable WAN Link Failure Detection, select VRRP Options in the Advanced Connection Options menu. The
VRRP Options menu appears.
