Chapter 3 Switch Management: Configuring Out-of-Band Deployment
Configure OOB Switch Management on the CAM
To Change Default SNMP
Step 1 Go to OOB Management > Profiles > SNMP Receiver > Advanced Settings (Figure 3-27).
Figure 3-27 SNMP Receiver > Advanced Settings
Step 2
Configure optional Advanced Settings as follows:
• MAC-NOTIFICATION Trap Timeout (default is 60 seconds)—The CAM timestamps the MAC
change notification/MAC move notification traps it receives, and examines the timestamp when the
trap is processed. If the time difference between the timestamp and the current time is greater than
the MAC-NOTIFICATION Trap Timeout, the trap is dropped. This configuration fields ensures
the CAM only processes timely traps.
• Linkup Trap Bounce Timeout (default is 180 seconds)—When the CAM receives a linkup trap, it
tries to resolve the MAC address connected to the port. The MAC address may not be available at
that time. If the CAM cannot get the MAC address, it makes another attempt after the number of
seconds specified in the Linkup Trap Retry Query Interval field. In order to keep the port
controlled and limit the number of times the CAM tries to resolve the MAC address, the CAM
bounces the port after the number of seconds specified in the Linkup Trap Bounce Timeout to
force the switch to generate a new linkup trap.
• Linkup Trap Retry Query Interval (default is 4 seconds)—When the CAM receives a linkup trap,
it needs to query the switch for the MAC address connected to the port. If the MAC address is not
yet available, the CAM waits the number of seconds specified in the Linkup Trap Retry Query
Interval field, then tries again.
