Unable to telnet to my Cisco switch since upgrading to Fibre 1 complete wifif

jka3725 — Sun, 24 Jul 2022 17:28:06 GMT

I have had BT broadband for the past 5+ years and in that time I have a home networking lab using a Cisco switch to act as a layer 2 device allowing printers and pcs to connect. That was all working fine until I upgraded to Fibre 1 complete wifi offering. I am now unable to telnet to that switch in order to manage it, the only saving grace is that all devices work and a reachable by ICMP.

I knew I seen this somewhere but it was so long ago I had trouble finding it.

Hi Les,

Many thanks for your prompt reply.

Having spoke to BT, they also concur that port 3801 is the one to try, that after a backup and a paperclip pinhole reset of the the hub.

Luck would have it, that I have a copy of Hyperterm from the heady days of Windows XP, managed to connect via telnet first time to my Cisco switch not using TCP/IP (SSH) but TCP/IP (Winsock).

Be grateful if you could pass this on to other poor souls that are in this predicament

Regards

John

If you tell anyone I said this I'll deny it but I first used hyperterm with, wait for it, Windows 3 but that's our secret right 🤣

Hope that sorts your problem, you'll have to post back to let us know

👍
