GS728TS, GS728TPS, GS752TS, and GS752TPS Gigabit Smart Switches 7. Use the Rate Limit (pps) field to specify the rate limit value for DHCP Snooping purpose. If the incoming rate of DHCP packets exceeds the value of this object for consecutively burst interval seconds, the port will be shutdown. If this value is N/A, then burst interval has no meaning, hence it is disabled. The default value is N/A. The range of Rate Limit is (0 to 300). 8. Use the Burst Interval (secs) field to specify the burst interval value for rate limiting purpose on this interface. If the rate limit is N/A, then the burst interval has no meaning and it is not applicable. The default value is N/A. The range of Burst Interval is (1 to 15). 9. Click Apply to apply the change to the system. Configuration changes take effect immediately. 10. Click Cancel to cancel the configuration on the screen and reset the data on the screen to the latest value of the switch. Binding Configuration The DHCP snooping application uses DHCP messages to build and maintain the binding's database. The binding's database only includes data for clients on untrusted ports. You can create static binding by manually configuring information in the bindings database. The DHCP snooping feature dynamically creates a tentative binding from DHCP DISCOVER and REQUEST messages. Tentative bindings tie a client to a port (the port where the DHCP client message was received). Tentative bindings are completed when DHCP snooping learns the client's IP address from a DHCP ACK message on a trusted port. DHCP snooping removes bindings in response to DECLINE, RELEASE, and NACK messages. The DHCP snooping application ignores the ACK messages as a reply to the DHCP Inform messages received on trusted ports. You can also enter static bindings into the binding database. When a switch learns of new bindings or when it loses bindings, the switch immediately updates the entries in the database.
