Hi Rawa,

This is a self signed certificate (not signed by any external certification authority) used for encryption. It is generated for example if you have ip http secure-server in your config or you are using SSL VPN.

Hi Rawa.

If you are confident that you don't need that certificate, you can remove it from the config by issuing commands like:

no crypto pki trustpoint TP-self-signed-4128971520

And the certificate will disappear.

But remember that if you will activate HTTPS-SERVER or SSH in the future, the certificate will be generated again... also because you need it for those protocols.

Hi Rawa,

this certificate provide an encrypted connection when you eniciate a connectiion thourgh using https or ssh.

you will accept the certificate when you initiate a connection to the switch through http / https.
