Issue/Introduction
Summary:
Cisco 6506 has not outbound data. Looking for net flow r9 configuration assistance.
Background:
We tried several changes in the netflow settings on the router overnight during a change window. Change flow input/output settings on multiple interfaces and VLAn's, but saw little impact. We still had only "in" data across the interfaces and "out" data on the "aggr".
We also tried switching to netflow V9 on the router. When we did that we got "no data at all" on any of the interfaces. We switched back to V5 and got data back after 1 minute.
---
Cust worked with Cisco TAC and re-applied the NetflowV9 config and we now have b-directional traffic.
The key change were....
flow monitor ipv4-NetQOS
no record platform-original ipv4 interface-full
record Interface-full-egress
Environment:
Cisco 6506, GatewayV2
Instructions:
After the correct configuration below... Bi-directional traffic is working..
On the Sup2T's with 15.x code it is critical to have the following command in the flow monitor: " record Interface-full-egress"
If you have "record platform-original ipv4 interface-full", you may have traffic in only one directions.
In addition you had to add the following commands:
flow record Interface-full-egress
match ipv4 protocol
match ipv4 source address
match ipv4 destination address
match transport source-port
match transport destination-port
match interface input
match interface output
collect routing source as
collect routing destination as
collect routing next-hop address ipv4
collect counter bytes
collect counter packets
collect timestamp sys-uptime first
collect timestamp sys-uptime last
LASTLY: You have to enable "ip flow monitor input" and "ip flow monitor output" on all interfaces and VLAN's to get the bi-directional traffic.
