How to acces switch remote

athan1234 · ‎12-07-2024

"I set up a switch, but I want to be able to access it; however, I can't access it via Telnet or HTTPS.

I believe the problem is that I did not set up the username. Is there any way to access it remotely?

I am attaching the main setup.

enable secret 9 $9$KkMgIVNmfnRs5E$uPJ/.n2Jcl2R2tgiFgH4oeD5ldhbwEtARFmnoNUjhZ.

no ip http server

ip http authentication local

ip http secure-server

ip forward-protocol nd

ip forward-protocol udp 47808

line con 0

You need username and password . And you need to use SSH, not Telnet.

Two steps still needed

1- config mgmt vlan svi with IP and connect PC have IP in same subnet of mgmt vlan

Note:- dont forget to config port that you connect you PC with same mgmt vlan

2- config username and password and privilege 15

Note:- access via browser using https not http

Hello,

Configure management vlan and assign a ip address and the default gateway in that vlan, if you want to SSH,

username xyz privilege 15 secret abc
enable secret klm

ip domain name xyz.com
crypto key generate rsa label SSH-KEY modulus 2048
ip ssh dh min size 2048
ip ssh rsa keypair-name SSH-KEY
ip ssh version 2

crypto key generate rsa
y
2048

!

ip ssh version 2
ip ssh time-out 60
ip ssh source-interface ( vlan )

!

line vty 0 15
exec-timeout 5 0
login
transport input ssh

Do you want to access through GUI, Please try this,

http authentication local
ip http secure-server
ip http client source-interface ( vlan )

Regards

I was checking another configuration, and it is working. I can't see any important lines you mentioned. The setup is working via HTTPS and SSH.

crypto key generate rsa label SSH-KEY modulus 2048
ip ssh dh min size 2048
ip ssh rsa keypair-name SSH-KEY
ip ssh version 2

crypto key generate rsa
y
2048

!

ip ssh version 2
ip ssh time-out 60
ip ssh source-interface ( vlan )

ip http client source-interface ( vlan )

I have attached the resume. The setup is working via HTTPS and SSH

I certainly agree with the suggestion that you need to use SSH rather than telnet. The partial config that was posted shows that remote access requires SSH

line vty 0 4

password cisco123

login

transport input ssh

It is not clear to me whether it is required to have a configured user ID or not. Since the vty are configured with a password it is possible that you might be able to login SSH using that password. The determining factor is whether that config has aaa new-model or not. without aaa new-model the password would be accepted. But if aaa new-model is configured then a configured ID and password would be required.

The posted partial config shows that HTTP is disabled. From the display in the OP it does appear that HTTPS is enabled. And it appears that it is prompting for a user name and password.
