cisco switch-3560 series
I need to know if cisco switch 3560-24PS can support dual ethernet connections.
We had initially planned for using two cisco switch 3560 for redundancy. But to reduce the cost and use one switch i would like to know if a single switch can support dual ethernet connections.
If anyone knows about any other cisco switch having 24 port that can support dual ethernet please let me know ASAP.
We had initially planned to connect two fiber connection from 2 differrent stations to the 3560 series through SFP port. Is this possible.
If we are using single switch with dual ethernet, is there any problems with the IP configurations. I am new to switches and anyone reply to help me would be appreciated

That way your protected regardless if a switch fails or if a NIC fails.
Kudos for your eye on redundancy however!Last edited by thecloudguy; 03-07-2006 at 02:23 PM.

Dear Adam
Thanks for the info
The system is designed like this. There are 2 switches in parallel. One of the switch is connected to workstation which is linked to one ethernet line while the second switch connectes to servers which is linked to both the ethernet lines. the two switch is cascaded using the SFP ports.
But now it seems tht if the first switch fails the workstation fails as it does not have link to the second ethernet. There will be no problem if the second switch fails as the servers in connected with second switch is connected to the other ethernet lines.
To solve this problem we have planned to use one switch. But you had mentioned that we cannot use single switch for dual ethernet. The dual ethernet is 100 base T.
Do you have any other solutions.
Thanks all for replying

What exactly do you mean by dual ethernet connections?
I was thinking you could get yourself a 2600 series router with 2 10/100 ethernet ports on it and plug both into the switch. Then if one nic goes down on the router(which is highly unlikely) then it wont stop traffick to the switch because the other ethernet port can simply be turned on.

Thanks.
But i need to connect fiber optic to the switch. I dont think that this will support GBIC card. Please let me know how i can connect fiber optic link to the switch too

For connecting the switch to the patch panel what type of patch panel with connectors does anyone recommend at both the ends of the patch cord.

Yes it does support fiber gige. You need the sfp gbic though I just put two of these in for a client. There just use cat5 cable for the patch panel connections.

Why would you want to do that? You should have the firewall plug into the patch panel or the switch directly for both of its connections and use vlans. I would go with a cisco pix. Exact model would depend upon your requirements.

Please see this link. YOu can view the diagram in large.
http://img.photobucket.com/albums/v6...than/cisco.jpg
1)Now please suggest if i should go for one switch or two switch. If so can i go for cisco 3650 or any other
2) What should be the connectors at patch panel. If i go for SC/ST type at the patch panel, will the switch support SC/ST type as the proposed cisco switch 3560 series has SFP module.
3) I have been suggested for fiber optics that i should go for Fiber Distribution frame which comes with patch panel installed within and patch cables. I do need cable organiser which is a requirement for the work. Is this ok for the fiber requirement or anythign else is required.
4) We need 6 core MMF with 6 core. I have been suggested to go for FDF with 12 ports for Patch panels. Is this the right thing.
5) As shown in the diagram, we need a firewall in the station which has servers and workstataions. Any suggestions for the firewall and where it should be placed.
Hope to see a reply

1) I have not shown the detail architecutre drawings. All the information from 20 stations are coming to the station which has servers and workstation. We will link this information to the company fiber optic. So we need a firewall for the station. could you now let me know where we should place the firewall.
2) is it still necessary for the firewall if there is already a firewall in the company fiber optic?

For your fiber patch panel, etc. use SC connectors. That is what is standard and what all datacenters use by default. Then get SC-LC jumpers to go from your patch panel to the SFP optics in your switch. SFPs use LC connectors. Regular GBICs use SC.

This is written in the tender document for patch cords. Is this information worth?
The construction of the cord shall be of 1064 cordage tightly twisted, 24 AWG, 8 conductor. The cord shall be terminated to a 8-position RJ-45 Modular Plug on both ends. The cords shall support the transmission requirements warranted to meet ISO/IEC 11801, EN 50173 or TIA/EIA 568, Category 6, Class E component specifications and standards.

The tender document calls for

is this information any use. Is this for termination for cat 6 cable rather than fiber optic?
