■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 page14
of this document.

server to the ATM Uplink module.
