Solved: Line clock settings 2Mb leased line

r.vanschendel · ‎10-11-2009

Hi

Believe it or not but a providor in Norway delivers not a clock signal in a point to point 2 Mb leased line.

What is now the best way to configure the clock setting on both routers ?

Normaly the config is; clock source internal But must you set that on both sides or only on one? And how do know that than both clocks are in sync ?

Hello Rene,

use clock source internal on one side and clock source line on the other side.

This should be fine.

>> And how do know that than both clocks are in sync ?

there is no direct way to see this you need to consider interface statistics over time if some type of interface errors don't increment over time clocking should be correct.
