Should the invent txclock command help eliminate some of the high errors seen on these Hssi point to point connections? I'm looking for a solution that will eliminate these high errors seen. Of course the provider always says no trouble found. The core router is a 7204VXR (NPR400). The config looks like this:
interface Hssi3/0
service-policy output PTC-TO-HAN-P2P-POLICY
load-interval 30
serial restart-delay 0
Then the other side is a cisco 3845 with the same type of module:
Mx HSSI-B Port adapter, 1 port. Config looks like this:
interface Hssi2/0
load-interval 30
serial restart-delay 0
service-policy output HAN-P2P-POLICY
4896 input errors, 4783 CRC, 0 frame, 96 overrun, 0 ignored, 17 abort

How many input packets ?

Hi, you are fine. Cannot use the byet counter because it has rolled over, but
514107407 * 800 B/pft * 8 =
01-30-2009 09:31 AM
Excuse the garbage in other answer. Seems like you have a BER better that 1/10^8. Usually circuits are deemed acceptable in that area.
514107407 * 800 B/pkt * 8 bits in byte / 4923 =
668350072

Ok, my question is would the invent txclock config assist in clearing up these errors?
Thanks,
Ted
