Cisco CMTS uBr10012 can't remote login throught telnet

Dear All,

I have a problem as title. But it only happen after I boot the CMTS uBr10012 a while and I can ping the IP CMTS have.

Below is my CMTS IOS version. Does anyone have the same problem on CMTS uBr10012?

If you need more data to this problem, please feel free to discuss.

Many thanks

Hi Ray,

Hi Ray,

I recommend:
- Check the cable, the SFP and the 5x1GE SPA or the PRE4's FA port where the IP is configured for telnet.
- Check the configuration file. You can send it to me: vatiacg "dot" kefo "at" gmail "dot" com
- Upgrade the IOS.
- Upgrade the SPA FPGAs with a PKG file.

If these are not help perhaps the port is failed.
I saw ports where the ping is OK, but there are no higher level traffic.
