■Relay Agent Information option (option 82) for Dynamic Host Configuration Protocol (DHCP). When forwarding client-originated DHCP packets to a DHCP server, the Cajun switch inserts this option, which contains information about the switch. The DHCP server uses this information to authenticate the client.

For information on how to enable option 82, see "Enabling Option 82 for DHCP" on page 12 of this document.

■Enhancement of the MAC Address Lock feature. This feature has been available in all previous releases. If a source MAC address is locked at a port (statically configured), a frame with that source MAC will be filtered if received on any other port on the same VLAN. With the enhancement, the feature immediately generates traps to identify all unknown source addresses. If, after sending a trap for an unknown source, the switch continues to receive traffic from the source, the feature generates a trap every 30 minutes until the traffic stops.

*Note: You can set the trap timer within a range of 60 to 1800 seconds (default) in one second intervals.

For information on how to enable the MAC Address Lock feature and traps for unknown source addresses, see "Enabling Traps for Unknown Source Addresses" on page 14 of this document.

■Load MIB for the ATM Uplink module, v1.1. This feature makes it possible for you to use SNMP commands to:

—Upload the startup configuration file of the ATM Uplink module to a TFTP server

—Download the startup configuration file from a TFTP server to the ATM Uplink module.

—Download a software image to the ATM Uplink module.
