Cisco 3750X Duplicate IP Address

Grant5333 — Thu, 26 Apr 2012 11:54:59 +0000

I’m currently having an issue with a 3750X switch connected to 6509E switch whereby the 3750X keeps rebooting/reloading and then producing duplicate IP messages. I have checked all the address and could not locate anything that match. I then went on to disconnect the 3750x and for some unknow reason it continued to recieve duplicate IP address error messages but from it’s own IP address. Can any one point me in the right direction to both questions.
The reboots and duplicate IP’s?

Batch file to run cisco commands

Vtrim — Sat, 05 Sep 2009 15:38:30 +0000

How do I create a simple .BAT file to run on 25 devices for the purpose of getting “show fabric errors” output.

And/or, does anyone know of a tool that I can do this with?

Connecting data closet switches to the core with redundant links

NetworkingATE — Tue, 02 Jun 2009 13:15:47 +0000

I’m moving our flat network which covers a three-story building and about 450 users to a subnetted network. I would like to know about connecting data closet switches to the core with redundant links. Can I implement OSPF on the core and connecting switches and eliminate spanning tree? In this environment do I really need VLANs per subnet or can I just subnet? I’m starting with new Cisco 6509 switches running VSS. I’m using the new switch to route between subnets. All data closet switches and server switches will have redundant links back to the core.

Can I update multiple Cisco AP’s and switches automatically?

They are All Cisco. APs 1200 series and switches from 6509, 4506, 4006 to 3524. I have SO MANY of them and need an easier way then updating them manually. They all use SSH
