HTTPS Certificates

When you register a SLX device in XCO, a new certificate is generated for the HTTPS server of SLX device. The certificate is generated with the default CA that XCO contains.

The following is an example of a certificate on SLX after device registration:

slx-171# show crypto ca certificates

Certificate Type: https; Trustpoint: none 
certificate: 
SHA1 Fingerprint=C1:F1:2C:BF:1A:47:7B:46:5D:8F:18:99:0E:58:CF:31:8C:58:5F:CC 
Subject: CN=slx-10.x.x.x.extremenetworks.com 
Issuer: C=US, ST=CA, O=Extreme Networks, OU=Extreme Fabric Automation Intermediate, CN=EFA Intermediate CA/emailAddress=support@extremenetworks.com 
Not Before: Jan 10 11:12:18 2022 GMT 
Not After : Jan 10 11:12:18 2024 GMT

You can use the CLI command only to install third-party certificates on a single device at once.

(efa:extreme)extreme@tpvm:/apps/test/certs$ efa certificate device install --ip=10.x.x.x
        --cert-type https --https-certificate server.crt --https-key
      my_server.key

WARNING: This will restart the HTTP service on the devices and services will not be able to connect till the operation is complete. Do you want to proceed [y/n]?

The device must have the new certificates uploaded:

slx-171# show crypto ca certificates 

Certificate Type: https; Trustpoint: none

Expiry and Alerts

The HTTPS certificate generated for SLX has an expiry of two years from the date of registration. The device shows the following error message when an HTTP certificate expires:
