Select an interface and click Edit.

Step 4

Enter the following information:

  • Trusted Interface—Select to trust or not trust the selected interface.

Note

Configure the ports that are connected to a DHCP server or to other switches or routers as trusted ports. Configure the ports that are connected to DHCP clients as untrusted ports.

  • Rate Limit (pps)—Check to limit the rate on the interface. If rate limit is enabled, enter the maximum number of rate that can be allowed on the interface.
