SG300-52MP : how to access config page

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! 

Regards,

 - 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.

Re: SG300-52MP : how to access config page

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!

Re: SG300-52MP : how to access config page

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 :

Re: SG300-52MP : how to access config page

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!
