Configuring the NAM
IPWRITE_MTU_FAILED = 0
IPWRITE_ENCAPFIX_FAILED = 0
Router#show ip flow export
Flow export is enabled
Exporting flows to 172.20.27.229 (3000)
Exporting using source interface Vlan2
Version 1 flow records
0 flows exported in 0 udp datagrams
0 flows failed due to lack of export packet
0 export packets were sent up to process level
0 export packets were dropped due to no fib
0 export packets were dropped due to adjacency issues
0 export packets were dropped due to fragmentation failures
0 export packets were dropped due to encapsulation fixup failures
0 export packets were dropped enqueuing for the RP
0 export packets were dropped due to IPC rate limiting
Step 3 Configure NDE as follows:
Router(config)#mls nde sender
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#mls rp nde-address 172.20.27.229
Router(config)#mls flow ip full
Router(config)#mls nde flow include protocol tcp
Router(config)#ip flow-export destination 172.20.27.229 3000
Note The UDP port number must be set at 3000.
Router(config)#ip flow-export source vlan 2
Router(config)#ip flow-aggregation cache as
Router(config-flow-cache)#enable
Router(config)#interface GigabitEthernet8/6
Router(config-if)#ip address 1.2.3.4 255.255.255.0
Router(config-if)#ip route-cache flow
When you configure a NAM module as an NDE collector, you should use the IP address of the NAM (set
up by sessioning into the NAM module).
Step 4 Synchronize NDE-related information with the NAM by entering:
Router#hw-module module 5 sync nde-info
This command may prompt you to reset the module. Use this command whenever the NDE configuration
and the NAM configuration is completed (such as a VLAN of the NAM management port and that VLAN
interface’s IP address and other configuration information).
Note If the NAM is not being used as an NDE collector, this step is not required. This step only applies to
the NAM that has version 1.2(xx). (NAM version 1.1(xx) is not supported).
