Hi 

I want to know how we can stop the loop in the network.if any user will connect the two I/O port with LAN cable . I think there is option of BPDUgaurd and BPDUfiter .

Please help

[Keny Perez]

Hi,

When you say "if any user will connect the two I/O port with LAN cable"... Do you mean ports in the IO Module in the 5108 UCS Chassis???

[Nishant Singal]

Hi,

Its something like - connecting two switch port with single cable,

Thanks

Nishant

[Keny Perez]

Nishant,

so your question is not related to the Unified Computing System (UCS)?

-Kenny

[Nishant Singal]

yes, my question is related to simple network in which the Pc is connected to switch and then router

Nishant

[Keny Perez]

ok, yeah...then my answer is the same...you may use different ways to secure your environment, you may use port security and BPDUGuard and shutdown interfaces that wont be used, for instance.

HTH somehow,

-Kenny

[Nishant Singal]

Thanks For your answer

I think the BPDU gaurd is only the solution as PC are changing on random basis so port security is  not possible, Please help the difference between the BPDU gaurd and BPDU filter or these command only for portfast interface or in any interface.

thanks

Nishant

[Keny Perez]

Nishant,

BPDU Filter= BPDUs are not generated/processed

BPDU Guard= Ports can be shut down if a BPDU is received

I hope that helps you, please dont hesitate to rate useful answers.

I am glad to help, just please remember this dicussion "Initial Set Up and LAN Connectivity" is about the Cisco UCS Servers, sorry if the tittle is a little confusing...

Thanks Kenny for replying,

Do you have any related to cisco UCS servers . I mean from where i can start to learn the things related to the same .

Any suggestion?

Nishant,

You may begin with this book that will be released shortly:

http://www.ciscopress.com/store/ccna-data-center-dcicn-640-911-official-cert-guide-9781587204548

If you dont want to wait, then you can use this material that was released last year and covers all for CCNA DC:

https://learningnetwork.cisco.com/community/certifications/ccna_data_center/dcicn/training_videos

And last but not least, you can try this really valuable material to master other technologies in the data center like: vPC, OTV and Storage Concepts:

HTH,

Thanks kenny

[Keny Perez]

Sure thing.  Don't forget to rate helpful content in this thread...

[Keny Perez]

If this is about UCS I can adjust my answer and keep on going with further questions, if not about UCS... well yes, you normally shut down interfaces that aren´t gonna be used in the switch to avoid the fact that anyone could just plug in a new cable and cause a mess.

Also, BPDUGuard is used for that as you mentioned, in fact, one would normally set a port as "edge" and enable BPDUGuard at the same time.

Hope that helps, let me know if there is anything else, UCS related, I could possibly help you with and it will be my pleasure.

2. I have UCS Simulator software is this possible to integrate with my GNS3  in Lab scenario ?

Reply will be appreciated ,

Thanks in advance!!
