I am testing rogue on wire using 5508 WLC and , I have a dedicated AP configured as rogue detector and configured the switch port where the Rogue detector is connected as trunk. I have plugged in an autonomous AP with open authentication to the same switch so that it can act as a rogue. On the WLC, I can see that Autonomous AP as rogue on Wire. But along with that I am seeing another AP as rogue on wire, even though i have plugged in only one Autonomous AP to the switch.

I have an old Dlink DI-604 that I'd like to configure to work as a switch. I think this is possible but not sure how to do it. Switches are cheap but if I could save a few bucks with some tweaking I'd prefer that.

I'm due to replace a stack of 2 x 3750 switches very soon with 2 x 3750Gs. These 2 current switches are the VTP server for a small domain. I have put the config on the new switches switches and I made it a server and used the same VTP domain and password etc and got the VLAN info ported over.Now I did this a while back and noticed the switches are in transparent mode with a revision number of 0, I need to set this back to server and swap the switches out but the revision will be lower than the client switches (around rev 200), what do I need to do?

such as the SLM2048T can be configured as an managed switch. Our schools have laptop carts and we want to put switches in the carts so that the laptops will be plugged into the network when not in use and software installs, updates, etc. can be pushed to the laptops while they're in the cart instead of waiting for them to be taken out, powered on and pushed over wireless. I can find a 10/100 48-port unmanaged switch, but I really want a gigabit unmanaged switch, but they don't seem to exist so I was wondering if a managed switch can be configured and used as an unmanaged switch. I don't want to have to assign a static IP address to the switch.

View 1 Replies View RelatedI've been tasked with finding all switch ports that are configured as Trunks. We plan to use LMS 4.2 to push (via Netconfig) new interface level commands to all user (non-trunked) ports. From my experience, this poses a problem because we do not know which ports are configured as trunks -vs- user ports.
Using Netconfig is not going to be easy since there is no way to script this. It would be great if I could run a show command on a switch and then have CWSI peform a change based upon the output.In other words, we need a way to run a job based upon the output of a command.

View 5 Replies View RelatedI am about rip and replace my current 3750G stack with a 3750X stack. I have trunked over vlan and vtp info and implemented a config so it should be ready to go other then moving cables onto it. However one thing I want to correct with our current setup is that the root bridge on our vlans including vlan 1 is on a separate set of switches that we control, however I would like this new stack to be the root bridge for all of our vlans. It will be the central set of switches that all other switches trunk into. I have pre-set higher spanning-tree priorities for each vlan on the new stack so I expect as I move lines into it that the tree will be re-calculated with it as the root bridge. I've ensured that there are no root guards on any of the other switches trunks and priorities are all at default levels for each vlan. Should I enforce root guard on the trunk interfaces of the new master stack? Most of the trunks are port-channels to the other switches - do I need to set root guard on the Port channel interface or on the individual ports that make up the Port channel? On both? Any other recommendations in regards to implementing spanning-tree with the new stack? I know using port channels eliminates a lot of potential for loops but not every trunk is and I'd still like to have spanning-tree on.

View 7 Replies View RelatedI currently have a Cisco 2621 powering a network at our co-location facility... It's a simple setup and is working well. The colo provides a redundant HSRP uplink, so I have their two uplinks going into a Dell switch. From that Dell switch I have a uplink into FastEthernet0/0 on the 2621, configured with my routing network, and then FastEthernet0/1 gets an address from my block of routable IP. FastEthernet0/1 then plugs into another Dell switch where I have all my servers connected. The servers get public routable IP addresses and use the address on FastEthernet0/1 as their default gateway.
It's time to upgrade off the 2621, so I aquired a Cisco 2811 which has two FE interfaces, as well as a modular HWIC-4ESW switch. My question is, can I get rid of the Dell Switch A in the setup above and just use the internal switch on the 2811 to accomplish the same thing? And I if I did this, would my two uplinks from the colo plug into ports 1 and 2 of that HWIC, and then port 3 would physically connect into FE 0/0? Or can I logically do that via configuration in the Cisco? I'm not sure how all this works and haven't received the new router yet, so I thought I'd get a head start and reach out to the experts.
My second question is unrelated, but each port on the HWIC switch cannot be configured as a network interface right? I'm pretty sure they can't as they aren't considered network interfaces but just thought I'd ask.

I would like to add the new switch to the stack without losing the config for the switch which is live. I understand that the highest priority of the switches becomes the Master but as the live switch is Priority 1, would chancing this affect the switches config, or would it lose connection at all?
Also when I plug in the new switch and it reboot how do I ensure it becomes the slave without rebooting the live switch?The cables on the switch do they have to go to port1 on the live switch and port 1 on the new switch or can they be port 1 and port 2?
