Fabric Security
Connection Security
Connection security provides an encrypted data path for switch management
methods. The switch supports the Secure Shell (SSH) protocol for the
command line interface and the Secure Socket Layer (SSL) protocol for
management applications such as EFCM BASIC and Common Information
Module (CIM).
The SSL handshake process between the workstation and the switch involves
the exchanging of certificates. These certificates contain the public and private
keys that define the encryption. When the SSL service is enabled, a certificate
is automatically created on the switch. The workstation validates the switch
certificate by comparing the workstation date and time to the switch
certificate creation date and time. For this reason, it is important to
synchronize the workstation and switch with the same date, time, and time
zone. The switch certificate is valid 24 hours before its creation date and 365
days after its creation date. If the certificate should become invalid, refer to
the Create command in the McDATA 4314 Command Line Interface Guide for
information about creating a certificate.
Consider your requirements for connection security: for the command line
interface (SSH), management applications such as EFCM BASIC (SSL), or
both. If SSL connection security is required, also consider using the Network
Time Protocol (NTP) to synchronize workstations and switches.
• Refer to System keyword of the Set Setup command in the McDATA 4314
Command Line Interface Guide for information about enabling the NTP
client on the switch and configuring the NTP server.
• Refer to the Set command in the McDATA 4314 Command Line Interface
Guide for information about setting the time zone.
