Port Security Manual Configuration
To configure port security on a Cisco Nexus 5000 Series switch, perform this task:
Step 1 Identify the WWN of the ports that need to be secured.
See the “Adding Authorized Port Pairs” section on page 1-11.
Step 2 Secure the fWWN to an authorized nWWN or pWWN.
Step 3 Activate the port security database.
Step 4 Verify your configuration.
This section includes the following topics:
• WWN Identification Guidelines, page 1-10
• Adding Authorized Port Pairs, page 1-11
WWN Identification Guidelines
If you decide to manually configure port security, note the following guidelines:
• Identify switch ports by the interface or by the fWWN.
• Identify devices by the pWWN or by the nWWN.
• If an N port is allowed to log in to SAN switch port F, then that N port can only log in through the
specified F port.
