Hello,
I know this is a stupid question but I've been searching for a lot of time... I can't access the admin page of my Cisco switch and I do not know why.
I can ping it, I'm connect to it but access to the admin page is filtered :
$ nmap -Pn -p 80,443 10.1.0.11 Starting Nmap 7.70 ( https://nmap.org ) at 2020-02-03 12:03 EST Nmap scan report for 10.1.0.11 Host is up. PORT STATE SERVICE 80/tcp filtered http 443/tcp filtered https Nmap done: 1 IP address (1 host up) scanned in 3.16 seconds
Can someone tell me why, or indicate me how to access it? Thanks!

- Do you have any sort of fire-walling solution between the cli-client (so to speak) and the switch ? If not sure then use a cli-client which is on the same subnet and or Vlan as the switch to start with.

- Assign an IP address to the switch management interface, then you should be able to access it through that IP and or the corresponding chosen DNS name.

Hello marce1000,
Thank you for your reply but I do not understand. I already have an IP assigned to the switch :
10.1.0.11
My issue is that, for unknown reason, the ports are filtered.
Is there any other port that I'm not aware of regarding the management interface, or should I use a special browser per exemple?
Thanks!

- Can you post the output of show ip http and show ip https ?

Hello,
Thanks again for the reply, but still, I do not understand your answer. How could I get these outputs from the switch if I'm unable to connect to the switch? That is my main problem : how to connect to the switch as these port are filtered?
Thanks !

- Try to access the device through the CLI in order to provide these outputs ; check the document below for guidance :

Yep! You were right!
After investigation, it appears that a policy was missing in the firewall to allow the https traffic between my computer and the switch.
Thanks!
