Cannot connect 2MB line on NM-4T

[clementxavier]

Hello,

I have a 2MB HDSL line connected to a 1721 with a WIC-2T on one end and a 2621XM with a WIC-1T on the other end. Everything works fine.

I am trying to replace the 1721 with a 3745 having a NM-4T. Not much luck. While the line protocol is up on the 3745 I cannot ping the 2621XM.

Any specific guide-lines with the NM-4T or the 3745. Have not tried forcing the clock rate.

Any tips/advise will be appreciated.

Thanks

Clement Xavier

Hello,

the NM-4T is synchronous only, so you need a clock. Can you post the configurations of both routers ?

Regards,

Hello,

try and configure the clock rate command on one of your serial ends:

2621XM - WIC-1T

------

interface Serial0/0

description AirPort to HQ @ 2Mb Leased

ip address 192.168.16.2 255.255.255.0

clock rate 2000000

or, on the 3745, enable the network-clock-participate on the relevant slot (not sure which one it is, I put an X as a placeholder) with the command:

3745(config)#network-clock-participate X

Regards,

Georg
