Enabling Traps for Unknown Source Addresses
To enable traps for unknown source addresses, you must first enable the MAC Address Lock feature. You can enable this feature and traps for unknown source addresses by using the Web Agent, CLI, or SNMP.
Enabling MAC Address Lock and Traps by
Using the Web Agent
To use the Web Agent to enable the MAC Address Lock feature and traps for unknown source addresses:
1.Manually add the “permitted” MAC addresses to the Address Forwarding Table (AFT).
For information on how to manually add MAC address to the
AFT, see “Adding Entries to the AFT Manually” in chapter 6 of
Cajun P550R/P880/P882 Switch User Guide, Version v5.0.
2.Enter the following information on the Switch Port Configuration page for the port:
a.Set the Allow Learning field to Disable.
b.Set the Known Mode field to Enable.
Note: To prevent flooding of frames from unknown source addresses, set the Known Mode field to Enable for all ports on the same VLAN as the port for which you are enabling MAC address lock.
c.Set the Intrusion Trap field to Enable.
d.Adjust the trap timer, if desired.
See “Configuring Switch Port Parameters” in chapter 5 of Cajun P550R/P880/P882 Switch User Guide Version 5.0, for information on how to perform these procedures.
Enabling MAC Address Lock and Traps by Using the CLI
To use the CLI to enable the MAC Address Lock feature and traps for unknown source addresses:
1.Enter Global Configuration mode.
The CLI displays the >(config)# prompt.
