Chapter 33 Configuring NDE
This example shows how to enable NDE from the PFC:
Router(config)# mls nde sender
Setting the Minimum IP MLS Flow Mask
You can set the minimum granularity of the flow mask for the MLS cache on the PFC. The actual flow
mask used will have at least the granularity specified by this command. For information on how the
different flow masks work, see the
If you configure TCP intercept, IOS Server Load Balancing (ISLB), Context-Based Access Control
(CBAC), reflexive ACLs, or Web Cache Communication Protocol (WCCP), the flow mask changes to
full.
Caution Changing the flow mask purges all existing shortcuts in the MLS cache, which on a Supervisor Engine 1
affects the number of active shortcuts. Be careful when using this command on a Supervisor Engine 1.
With a Supervisor Engine 2, NDE configuration has no effect on Layer 3 switching in hardware by
the PFC2.
To set the minimum IP MLS flow mask, perform this task:
Command
Router(config)# mls flow ip {destination |
destination-source |
interface-destination-source | full |
interface-full}
Router(config)# no mls flow ip
Release 12.1(13)E and later releases support the interface-destination-source and interface-full

keywords.
This example shows how to set the minimum IP MLS flow mask:
Router(config)# mls flow ip destination
To display the IP MLS flow mask configuration, perform this task:
Command
Router# show mls netflow flowmask
Router# show mls flowmask
This example shows how to display the MLS flow mask configuration:
Router# show mls netflow flowmask
current ip flowmask for unicast: destination address
