Cisco 3560G and dual internet connection
Posted on 2009-04-21
I have a general question about the Cisco 3560G and how to best use it to route traffic.
We have two different connections to the internet, and old T1 and a new 4mb (Ethernet connection).
The network over all is a big un-managed switch network. There are 5 or so vlans all in the 3560G. The majority (80%) of 400 nodes are connected to stacked switches. Then these stacked switches are connect Cisco with a single link. For example, three switches are connect to each other, and one switch is linked to the Cisco. Lastly, all nodes in the stack switches have as their default gateway the T1 firewall device which is also connected into a un-managed switch.
The network as-is is working. There are performance issue, but at the moment are untraceable. (ugh)
I was thinking of taking every un-managed switch and directly connecting it to the 3560 and assigning it a vlan. I thought this would help make the traffic flow more efficient.
As for the wan connections, I was thinking of assigning a ports on the Cisco as well and then somehow use the switch to "load balance" the traffic to the net.
I am looking for ideas on how to proceed to make the best use of this Cisco.
How do I best use the two WAN links?
Any ideas would be greatly appreciated.
Also, if you would like more info, let me know.
PS. Survey: What this question worth?
