Re: 6500 performance issues.

MANIVANNAN NAGARAJAN · ‎05-13-2010

Hi,

We are having two 6500 series switches in same floor. In First switch 6748 line cards is installed with DFC-3 card.

In our Editing workstations are connected to this line card for higher cache as well performance.

In second switch I have installed 6748 line card with DFC-3 card today morning successfully. Unfortunately editing workstations

are not working on new switch even though it is same hardware / switching capability.

When I am troubleshooting I found below difference between two switches kindly refer below.

4^th Floor 1^st Switch – Editing workstation is working fine.

Please let me know can we change switching mode from bus to truncated or flow through on 2^nd switch.

Thanks in advance and appreciate the support as ever.

Hi Nagarajan,

Are you running the same IOS in both devices?

Reza

MANIVANNAN NAGARAJAN · ‎05-15-2010

Both IOS are exactly same.

stonnet72 · ‎05-13-2010

Please do a sho ver to see if the IOS versions are a match on both switches. Please post this information.

thank you

jorge.calvo · ‎05-14-2010

Hello,

If you want to allow the modules to run in truncated mode you should use the command:

fabric switching-mode allow truncated

The flow through mode is only supported by CEF256 modules when there is no switch fabric present. If you have CEF720 modules, you may use truncated mode.

Hope this helps.

MANIVANNAN NAGARAJAN · ‎05-15-2010

Hi,

Thanks for your response.What will be impact when i will switchover truncated and what

is Cisco's recommendation. If i switch-over to trucated do i require reboot. can any one help on this.

francisco_1 · ‎05-14-2010

The would make sense. Looks like the first switch you have a Cat 6513 with sup 720 engine with dual full fabric-enabled cards in slots 9 - 13 for dual fabric connected cards for eample WS-X68xx and WS-67xx hence why you are using compact mode used for those cards. The compact mode is used when no nonfaric-enabled modules are installed.

what is the sup on the second switch?

post "show module" on both switch..

MANIVANNAN NAGARAJAN · ‎05-15-2010

Both are sup-720.
