Configuring NDE on Catalyst 6000 Series Switches
Follow the steps below to configure NDE on Catalyst 6000 Series switches
Configuring 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 |
