Cisco issue

Have a weird one here. Have something like 17 sub interfaces on my
serial2 interface on a cisco 7206. These are our connections via T-1
to our remote sites on either cisco 1751's or 1841's.

Just recently one of the T-1's started dropping packets like crazy, T
is bouncing all the time, have a lot of CRC errors on the 7206. Qwest
seems to think it's our equipment, but I don't see how a sub interface
could go bad on a router like this.

I would think the whole serial interface would go & everyone would have
problems connecting.

Suggestions?

Re: Cisco issue - Update

Never would have figured, but rebooting our core router *seems* to have
taken care of the problem.
