7507 Netflow - no flows showing up for specific port

Hello,

I have a 7507 with IOS (tm) RSP Software (RSP-K4PV-M), Version 12.0(32)S5, RELEASE SOFTWARE (fc2.

I have "ip route-cache flow input" enabled on several ports but when I view "sho ip cache flow" I only see flows from certain ports.

In particular there is a VIP4-80 with a PA-GE in slot 6 that has 6Megs of inbound traffic, yet no flows appear. CEF distributed is enabled globally.

Is there something I need to do to see flows for this port?

Thank you,

Bryan

Re: 7507 Netflow - no flows showing up for specific port

Do you get an error message when you enable cef distributed such as:

SFGECISSF1/sf1(config)#ip cef dist

SFGECISSF1/sf1(config)#^Z

SFGECISSF1/sf1#

%SYS-5-CONFIG_I: Configured from console by console

%IPC-5-SLAVELOG: VIP-SLOT12:

%IPFLOW-2-CACHEINIT: Error initializing IP flow cache

In that case you would be hitting bug: CSCdt07408

Else can you post your outputs of the configuration and the show ip cache flow?

Hello,

DCEF is already running. There is no error when you re-enable it. Here is some oputputs:

no ip unreachables

Only that local flow shows up for g6/1/0. There are several other flows on a serial interface of this router that show up.
