Have 2 routers Cisco 2821
Site A serial0/0/0:1 10.52.1.1
Site B serial? T1 as well 10.52.1.4
ISP is pointing that the current extremely degraded bandwidth could be caused by our T1 cards. We have packet loss 6-7%
Please give Very simple commands, steps, ext and explain well.
I want to check to see if there are any errors in the cisco concerning the T1 cards... I'm a Windows Administrator, I really do not no much about the router. I count it great that I can telnet into it even.
Thanks in advance!
