System logging over TLS encrypts communication between an OS10 switch and a configured remote logging sever, including: • Performing mutual authentication of a client and server using public key infrastructure (PKI) certificates • Encrypting the entire authentication exchange so that neither user ID nor password is vulnerable to discovery, and that the data is not modified during transport Confguration notes System logging over TLS requires that: • X.509v3 PKI certificates are configured on a certification authority (CA) and installed on the switch. Both the switch and syslog server exchange a public key in a signed X.509v3 certificate to authenticate each other. For more information, see X.509v3 certificates. • You configure a security profile for system logging as described in Security profiles. Configure system logging over TLS 1. Copy an X.509v3 certificate created by a CA server using a secure method, such as SCP or HTTPS, as described in Manage CA certificates. Then install the trusted CA certificate in EXEC mode. crypto ca-cert install ca-cert-filepath [filename] • ca-cert-filepath specifies the local path to the downloaded certificate; for example, home://CAcert.pem or usb://CA-cert.pem. • filename specifies an optional filename that the certificate is stored under in the OS10 trust-store directory. Enter the filename in the filename.crt format. 2. Obtain an X.509v3 host certificate from the CA server as described in Request and install host certificates: a. Create a private key and generate a certificate signing request for the switch. b. Copy the CSR file to the CA server for signing. c. Copy the CA-signed certificate to the home directory on the switch. d. Install the host certificate: crypto cert install cert-file home://cert-filepath key-file {key-path | private} [password passphrase] [fips] When you install an X.509v3 certificate-key pair: Troubleshoot OS10 1321
