Cisco Switching/Routing :: 3750 Lab Switch Control And Config Restore
Nov 16, 2011I am in the process of setting up an interop lab for some engineers. The enviornment will consist of some 3750's, H3C's and ProCurves. My concern is that the end user will have Priv-Exec access for CLI usage on the 3750's and they can change the "en" password (I hope they don't but it has happened).Is there a way I can "break in" during the boot process to reset the password? The reason I am doing it this way is because I have an Altiris server with rebuild automation scripts in xpect and I would like to automate the process so I do not have to use a manual factory default reset.

Cisco Switching/Routing :: 3750G Replacing VTP Server Switch
Apr 8, 2013I'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?

Cisco Switching/Routing :: 3750G / Switch Loses Connecting To Distribution SW

View 5 Replies View RelatedCisco Switching/Routing :: 3750G Spanning Tree On New Switch Stack
Nov 3, 2011I 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.

Feb 29, 2012I currently have Cisco 3750G which is currently live and active and fully populated and only have remote access.
I have an additional same switch which I would like to stack. My initial plans were to have 2 GIbit etherchannels, but I came across the option to Stacks both switch with each other.
When I do a show switch on the live switch its set as a Member: [code]
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?

Cisco Switching/Routing :: SF 300-24 Switch Won't Boot After VLAN Config / Reboot
Jul 28, 2012I was trying to configure an SF 300-24 for use in my home and obviously did something dumb. It was working fine. The f/w was updated and I had configured 2 VLANs. VLAN2 was ports 1-6+GE1 for IPTV streaming and VLAN3 was ports 7-24+GE2 and GE3 for the rest of my LAN. I was plugged into GE4 and was configuring the switch with a laptop. GE4 was the only port still on the default VLAN1. I chaged the default VLAN to VLAN3, which forced a reboot and the switch never came back up. Attached is what I see when I connect to the console port: [code]
I can't access to GUI using it's static IP or it's default IP on any port and the console never reaches the point where I can log in. The System light is flashing green but the boot sequence never progresses past what's in the screen shot. I tried to do a hard reset using the recessed button on the front panel but it does not seem to have any effect, no matter how long I hold it down.

Cisco WAN :: 3750G / How To Identify Source Of Runts
Aug 27, 2012I am getting input errors/runts on 2 of my gigabit interfaces that connect to our WAN service provider's network. In relation to total packets, its not a large number, so its probably not a big deal, but I'd just like to find the source so I stop seeing the errors in Solarwinds. Our service provider says that they don't see any errors on their side, but the errors are incoming to us.
I've tried to capture the traffic with Wireshark, but discovered that often these packets are either discarded or padded by NICs so Wireshark will not see them, or at least will not see them as undersized.
Is there any other way I can capture these packets so I can find the source and figure out how to stop them? Our equipment is 3750G running 12.2(55)SE. Its not a trunk port. I know there was a bug in prior IOS that would cause some frames to be marked as runts even though they were forwarded successfully.
