2-26 Firmware User Guide
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, over taking 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 Firmware Version 8.5.1, the firmware offers VRRP Options to detect Layer 3 link failures on the
WAN. When you enable this feature, the 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 Netopia Router will send continuous Pings, so the WAN link will stay up and idle
timeout will not occur.
See “Vir tual Router Redundancy (VRRP)” on page 7-34 for a detailed description of VRRP and how to create
Vir tual Routers.
To enable WAN Link Failure Detection, select VRRP Options in the Advanced Connection Options menu. The
VRRP Options menu appears.
