Re: IOS downgrade!

[Benson Omollo <omollo at wananchi.com>]

Hi Philip,

The reason for my upgrade is to sort the problem of clocking on 2600 series, I couldn't get the work around patch in cisco page.
My image is c2600-i-mz.120-3.T3 on 2600 cisco.
I can't get a 512k lease line thro' Rad modem to work with it...alot of CRC errors while cisco 2514 doesn't record any error!.

I realized I couldn't get IOS 11 to work with it...it could recongnize fastethernet.
I will appreciate more info. on the this.

Thank you,

Omollo Benson
