Hi..

I hav a Cisco 3700 with two NM-HDV (one E1 port in each NM-HDV). The NM-HDV is connected (back-to-back) to two Cisco 2800.

If each E1 port is configured to obtain clocking from the line and "show network-clocks" shows that the C3700 router is using the backplane as the clock reference. Will there be any potential clocking issue?

Do i need to configure "network-clock-participate" ? The default is "no network-clock-participate"

Any comments greatly appreciated.

Thanks

EW
