Cisco 6509 chassis with multiple card with different daugther card

[guillaume.chartrand]

Hi, I have a Cisco 6509 Chassis with these module inserted

1   10  WiSM WLAN Service Module               WS-SVC-WISM-1-K9
2    8  8 port 1000mb GBIC Enhanced QoS        WS-X6408A-GBIC
4   48  CEF720 48 port 10/100/1000mb Ethernet  WS-X6748-GE-TX
5    2  Supervisor Engine 720 (Active)         WS-SUP720-3B
8   48  CEF720 48 port 10/100/1000mb Ethernet  WS-X6748-GE-TX

I recently buy a refurbished CDF720 48 port module (module 4), but I didn't specify and verify the sub-module on it.

Here is all the sub-module of my module

1  Centralized Forwarding Card WS-SVC-WISM-1-K9-D
4  Distributed Forwarding Card WS-F6700-DFC3A
5  Policy Feature Card 3       WS-F6K-PFC3B
5  MSFC3 Daughterboard         WS-SUP720
8  Centralized Forwarding Card WS-F6700-CFC

and here is the fw and sw version

Mod MAC addresses                       Hw    Fw           Sw
--- ---------------------------------- ------ ------------ ------------
  1  xxxx   2.2   12.2(14r)S5  12.2(18)SXF1
  2  xxxx   1.1   5.1(1)CSX    8.5(0.46)RFW
  4  xxxx   2.5   Unknown      Unknown
  5  xxxx   5.6   8.5(2)       12.2(18)SXF1
  8  xxxx   2.6   12.2(14r)S5  12.2(18)SXF1

When I hot-add the module 4, it was disabled by the chassis and the message in the log was

Mar 21 10:11:37.012: %C6KENV-SP-2-DFCMISMATCHMINOR: Module 4 DFC installed is in
compatible with system operating mode. Power denied.

I read that sub-card or sub-feature cannot be mix, the upper feature will downgrade itself to work correctly, is it right?

I don't want to reboot the switch and don't know what will do the system. If someone can confirm that I can reboot without stress and the new card, even if it's better than the other one will be downgrade itself to make comatible.

If I type the command show platform hardware pfc mode

I got PFC3B

Hi,

A couple of links for you to read.

http://www.cisco.com/c/en/us/support/docs/switches/catalyst-6500-series-switches/107258-C6K-PFC-DFC-CFC.html
http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst6500/hardware/Config_Notes/78_11627.html

So you need to repower the whole switch with the module installed in slot 4.

As you have a PFC3B on you sup720 (slot 5) when the module with the DFC3A in slot 4 starts running
your PFC will regress to to PFC3A mode.

Hope this helps
Regards
Alex

Ok thanks, I already read the first link, I will ask my reseller if we can change the DFC card instead of regressing.

Thanks for you help

Hi!

The linecard will not work even after the reload since you have a CFC 3A and a DFC 3B.

4  Distributed Forwarding Card WS-F6700-DFC3A
5  Policy Feature Card 3       WS-F6K-PFC3B

All linecards in the chassis MUST be of the same family. CFC 3A WITH DFC 3A. You cannot combine 3A with 3B or 3A with 4B/A.

Hope it helps, best regards!
