Follow the steps below to configure NDE on Catalyst 6000 Series switches
Enter privileged mode on the Supervisor Engine and issue the following commands to configure NDE:
Command | Purpose |
set mls nde {hostname|ip_address} 9996 | Specifies NetFlow Analyzer as the NDE collector and the configured Netflow listener port as the UDP port for data export of hardware-switched packets. |
ip flow-export destination {hostname|ip_address}9996 | Specifies NetFlow Analyzer as the NDE collector and the configured Netflow listener port as the UDP port for data export of software-switched packets. * |
set mls agingtime long 64 |
Breaks up long-lived flows into 1-minute fragments. This ensures that traffic graphs do not have spikes. It is important to set this value to 1 minute in order to generate alerts and view troubleshooting data. |
set mls agingtime 32 | Ensures that flows that have finished are periodically exported. Ensure that the set value is not too low, else NetFlow Analyzer may report traffic levels that are too low. |
set mls flow full | This sets the flow mask to full flows. This is required to get useful information from the switch. |
set mls nde enable | This enables NDE |
*To monitor data and statistics about Layer 3 traffic that is switched in software by the MSFC, you must specify the NDE collector and UDP port on the MSFC.
This requires that you enter the ip flow-export destination command on the MSFC.
Use the show mls debug command to debug the NDE configuration |
