FTP service issues on ASR 1002

Quoc Vinh Ngo · ‎03-18-2014

Hello all,

I have 1 Cisco ASR 1002 configured as a normal edge router connecting to ISP.

When i used ftp service, the FTP service run normally in the morning but it is slower by afternoon and till the end of the working day, client PC can't work anymore

So, i restart ASR 1002 and it work well again

The next day, i replaced ASR 1002 with Cisco router 2801, configured the same extractly. And there's not problem anymore.

Then, I tried ASR 1002 and it's in trouble again. Now, i have to use 2801.

Can anyone help me, please
