network design

good Morning\Afternoon networking gurus

i am trying to build in some redundancy based in the nw design attached.

please note that i have only one 5400zl chassis in the core.
Any suggestions?


Thank you all

Re: network design

Your question is very open...
First suggestion would be : add another 5400
But I don't think thats's what you wanted to hear?

Question : does the 5400 does any other function in your network eg. routing?
If so there will be no much need for other physical paths when your router in the network is down....

Re: network design

hello there, the ideal purpose for the nw design will be in the future add a new 5400zl in the core, but not for now, i understand perfectly that if my only core switch goes down i have no redundancy at all.
I am thinking more about in path redundancy, if a mini-gb link goes down i want to my 2610 keep working with no problems with the alternate psychical path.... any ideas???, and yes the switch will have routing functions.
Thank you

Re: network design

then for the bottom 2610's your drawing allready shows a redundant link.
only the left and right switches need a second link, as the "stack"-connection possibly only is for management and does not do any data-traffic?

Re: network design

Thanks for the quick answer.
So stacking is not a solution, to my redundancy issue.
Due to the small distance between those two switchs, it is possible to create a backup uplink using a UTP cable and manage a possible lost of link in the fiber automatically.

One again many thanks.

Re: network design

Yes stacking was meant as:
"Stacking capability: single IP address management for a virtual stack of up to 16 switches"
So only for management, not comparable to cisco StackWise

Although once on the forum I was pointed out that from some models/firmware version on It would have more capabilities, but cant find this link at the time.
