I am looking few information on IOS up-gradation for the switch WS-C3750G-48TS-S . I loaded new Image on the flash and current flash and sh boot as below
1) I would like to set boot sytem parameter for the new IOS and secondary old IOS as well is below command works??? if IOS not coming up with new one 12.2.58 is it boots with old 12.2-35 ?
boot system flash:c3750-ipservicesk9-mz.122-58.SE2.bin;flash:c3750-ipbase-mz.122-35.SE5
2) If I set only boot system flash:c3750-ipservicesk9-mz.122-58 , if new image corrput swicth will check valid image and boot up with old image ?
3) If switch went to room1 switch mode and still I have valild running IOS c3750-ipservicesk9-mz.122-37.SE.bin at flash memory, how to restore with old image
I have a couple of 3750G-24T-E switches running IOS 12.2 I would like to upgrade to IOS 15.x. Is this possible? Where do I find some information on the required licenses and costs? I must admit that the cisco search function did come up with a few pages but i was not able to extract the required information. I have not used the new software activation features yet.
I'm trying to upgrade the IOS ver on a 3750G stack (2 switches), but the img on the switch is too old.The stack is running IOS c3750-i9-mz.121-19.EA1d.bin, and when I tried to upgrade to a newer version, I tried to go to IOS ver c3750-advipservicesk9-mz.122-35.SE5.bin since I need to enable ssh on the switch, but the switch did not reload.
Here's a prtscreen of the switch ver:

what IOS ver can I upgrade to that is not already deferred?
I am having a switch 3750G (WS-C3750G-24TS-S) running a software version (c3750-ipservicesk9-mz.122-55.SE6.bin) and using the PBR with IP SLA.While, i am applying it on interface, it says not supported....

I have one switch 3750G12S I joined the company new, I found that they want to replace it with Alcatel stack switches. I didnt configure this Cisco switch before. how to configure it. I have 4 other new cisco switches in the topology which is not created yet. the 4 switches are all 2960.
have one 3750G stack with 4 switches and this stack is presenting the follow log message:
%PLATFORM_UCAST-4-PREFIX: One or more, more specific prefixes could not be programmed into TCAM and are being covered by a less specific prefix, and the packets may be software forwarded.
In this stack we are using the layer 3 with OSPF routing, and the current sdm prefer is default:
switch-01-3750#sh sdm prefer The current template is "desktop default" template. The selected template optimizes the resources in the switch to support this level of features for 8 routed interfaces and 1024 VLANs.(code)
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?
I am having an issue bypassing a switch 3750G series. How i can bypass the old configuration in the switch.i have tried the CTRL+BREAK at startup but it wont work.
The two stacked Cisco 3750G Access switches on a particular floor in my coy just lost connectivity to the distribution Switch this morning. This meant that all Users connected to it couldnt connect to the Internet nor access local network resources.I couldn't ping the Switch IP, I couldn't also access the Switch via Console port. Each time I tried to gain access via the console port, I keep getting "Authentication Failed" message.What should I do next? How do I gain access to the Switch?
I 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.
I wan to migrate from a router 2800 to L3 switch 3750G , the thing is that we have several vlans and we use a router sometimes with each interface configure with correspoinding vlan subnet ip to route traffic between vlans there is no static or dynamic routing only directly connected interfaces on router routing traffic to each other ?How would i configure a L3 switch interface for simillar functionality , below is my current router configuration
! ip domain name yourdomain.com multilink bundle-name authenticated ! vtp mode transparent
I try to connect two switch Catalyst 3750G without success.switch1 (192.168.2.10 vlan 2) <=> (192.168.2.11 vlan2) switch2.I use this configuration for swich1 [code]
I am cascading one new switch 3750G (int Gi1/0/1) with an existing 3750G (int fa1/0/26) switch.. But the interface fa1/0/26 goes in err-disable state even after NO SH.. also i have diable Spanning treebpdu guard and disable spanning tree portfast. But still the issue is not resolved.
I 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?
Has any come across show ver memory details on 3750G-48PS as below, One of our Catalyst 3750G running software 12.2(44)SE2 shows unexpected DRAM as below:
cisco WS-C3750G-48PS (PowerPC405) processor (revision F0) with 0K/12280K bytes of memory. This would equate to around 11MB memory which does not seem right... Is it a known IOS bug?
Why isn't a GUI upgrade possible instead of CLI initiated upgrade?Is this (GUI) only for patch upgrades or is it a valid upgrade path to use the Cisco Prime's GUI (Administarion; Software Update) in order to upload update file. Check for updates gives no results though successful login to [URL].
we purchase only Cisco Supervisor Engine VS-S720-10G and use it in our old C6509-E chassis.Now the supervisor engine was dead,(means not working and no LED's are ON). How can i claim the RMA from cisco?
We purchase from one of our partner. We send it to them,they are not able to find the Serial number from the Supervisor Engine module (Because lot of serial numbers are on the board). Also the customer through the catoon.
Now how we can know which is exact serial number of sup? How to get RMA from the Cisco on which serial number?
I have a few 24-port Cisco 2960G Switches (model WS-C2960G-24TC-L) that I upgraded to IOS Release 15.0(1)SE2 using the web interface. I am now trying to upgrade those switches with the new release, 15.0(1)SE3, however I seem unable to do it, I have tried this on two switches so far, both have been upgraded to SE2 just a couple months ago or so, and both of them will not accept the SE3 upgrade, basically, I can select the tar file in the web browser and click "Upgrade" but when I do the status never changes from "Loading the tar file to the switch". I have tried multiple times from multiple computers using many different web browsers, including IE6 which is listed as supported. I have let it go for as long as 1.5 hours but to no avail.I also had a few idential switches here that had never been upgarded to SE2, I have had no problems loading SE3 onto them using the same method so it would seem that the tar file I have downloaded is valid.
I am upgrading a Cisco 6506E VSS from 12.2(33)SXI5 to 12.2(33)SXJ5 during a maintenance window. So I have plenty of time to reboot the VSS. Confirm below is the correct procedure. I have manually copied the new IOS to both active and standby Sup720s.

I was going through the below cisco document and there are a few more steps as below: Is it necessary?
We have a Cat2960-S Series PoE+ currently running 12.2(55) SE5 ios with SW image C2960S-UNIVERSALK9-M.We want to upgrade the ios to the lastest version but found there are 2 version: 12.2(53) SE2 and 15.0(1) SE.Which is the best & suitable for upgrade?
i am trying to upgrade the firmware in my C2960 switch to 15(1) SE2, and i get the error:Failed to execute the command archive download -sw /overwrite /http iosFile
We have two 3560G-TS-E running 12.2(35)se2, configured as HSRP. Both are running ntp config "ntp peer 210.72.145.44" and it's pretty well that they get the correct time. Yesterday I upgraded the second device to IOS 12.2(58)se2 and ntp doesn't work now. I checked doc that 12.2(58)se2 runs ntp default version 4 so I change to "ntp peer 210.72.145.44 version 3" but still not work. I put here "show ntp" result for different IOS.

I have a 3550 switch right now, and need to upgrade to a gigabit switch, so I'm looking at a 3560G-48. For some reason I purchased an EMI version of my 3550, but run the ipbase image...what I need to look for - is a 3560G-48-s good for what I need?
I am trying to upgrade my cisco WS 2960 24 TC-L switch with the IOS image c2960-lanbasek9-mz.122-55.SE6.bin and my existing IOS image is c2960-lanbasek9-mz.122-50.SE5.bin. when i am copying it to flash, it is getting copied but when i tried to boot it after entering command boot system c2960-lanbasek9-mz.122-55.SE6.bin , it gave me an error.
later that by mistake i typed delete /force /recursive flash:now, I am unable to load new IOS error loading "flash:c3750e-universalk9-mz.122-55.SE5.bin" Interrupt within 5 seconds to abort boot process.Boot process failed...
I have installed Cisco 2955 Switch which already have x.x.x.x EA12 IOS and I copied x.x.x.x.EA13 into the flash: with intention to have EA13 enabled for IOS. I set the Global config for boot system by 'boot system (no falsh)x.x.EA13;x.x.EA12' but then also no luck and was showing EA12 in 'sh ver'. I then deleted the EA12 IOS and set the 'boot system flash:x.x.EA13'. I also had varified IOS EA13 by 'verify flash:IOS Filename', it verified the IOS.
But when I reloaded my switch, I'm unable to login and its in 'switch:' prompt (ROMmon mode - I believe). I then tried for flash_init, load_helper, dir flash: (showing me EA13 there) and finally boot flash:IOS Image file but no good news here... Output like this
Error loading "flash:IOS Image File EA13" Interrupt within 5 seconds to abort boot process. Error loading "flash:c2950-i6q4l2-mz.121-12c.EA1.bin"Interrupt within 5 seconds to abort boot process.
My guessing is that the IOS is corrupted (but its not showing me Error loading Image blabla...) I'm trying with EA14 of 4MB and I have 3 MB free spare and decided to remove EA13 first then through XModem try to upload EA14.
Any useful way and recommend me deleting EA13 and upgrading EA14... Also option to set boot image with having two IOS at the same time for permanent use.
