7x stack WS-C3750E-48TD-E orignal code 12.2.35...i wanted to get it to 15.0.1 so as a test i disconnected top switch (not the master ) and installed via archive download-sw /allow upgrade 15.0.1.tar. and it worked away fine...
so i moved onto the stack, issued the same command, image loaded rebooted and stack hung..Consoled in and switch was unable to boot..looping on trying to load flash. [code]
I have two Switches which i need to put in a same stack - WS-C3750E-48TD and WS-C3750G-48TS . Possible to do so and also which IOS to put in both the switches as WS-C3750G-48TS is having lower RAM and flash.Whether can i put following IOS in these switches and connect them in a stack as i have read that IOS -- 15.0.1. SE are compatible with both the switches.
a . c3750e-ipbasek9-mz.150-1.SE.bin in switch - WS-C3750E-48TD
b. c3750-ipbasek9-mz.150-1.SE.bin in switch -- WS-C3750G-48TS
Is that possible add WS-C3750-48TS-E to ws-c3750e-48td stack?

I checked and found two registered bug id: CSCtq86186 / CSCso81660.I would like to know what is the best IOS version to update my switch, IOS 15.0.2 SE2 or 12.2.58 SE2, by the way, my environment is very critical (data center) and the version 15.0.2 SE2 is very recent, but its stable ?In both versions the problem are fixed?
IOS upgrade tried on the stack of 2XWS-C3750X-24T-S , Upgrade was tried to support WCCP on the platform. Current version is Cisco IOS Software, C3750E Software (C3750E-UNIVERSALK9-M), Version 12.2(58)SE1, Not able find any IP Plus ios in the site ? Only available are IP base and Universal K9 , Tried upgrading to c3750e-universalk9-tar.122-58.SE2.tar by using stack upgrade method as per document [URL]
Upgrade fails with error :
%Error opening flash:update/info (No such file or directory)
ERROR: Image is not a valid IOS image archive.
Why current ios is not supporting WCCP , I hope it is there in the featureset. ( tried "sdm prefer routing" but no success) Does c3750e-universalk9-tar.122-58.SE2.tar will give me wccp support ? What is the issue with my upgrade and how do I do a successfull upgrade ?
applied an iOS update to a stack via tftp. I used the archive Download-sw tftp:// method. I rebooted the stack after complete and it never came back up. I discovered the master switch upgraded but not the member. The member was sitting there with all amber lights on and frozen after the iOS load. The master wouldn't finish boot until I removed the member from the stack. I had a version mismatch and they would not communicate.

With this new configuration the switch has rebooted again.Why on a standalone switch the stack is rebooting my system?Is it any feature to disable the stack?
We have a stack of a 3750E with a 3750X, when we turn off the master, a disconnection occurs for around one minute while only one request timeout is seen when the slave is turned off. Is this normal? Details: in other words, when the slave switch is elected as the new master all the port-channels and some physical ports become in 'down' state before reobtaining the up state again, this results in a one minute outage. The question is: is it normal to have a layer2 control traffic interruption when the master fails and re-election occurs and if yes, what is the normal downtime in seconds. the layer2 control information such as port-channels LACP protocol are not synchronised to all slave switches by the master?
View 7 Replies View Related The Catalyst 3750 switch reboots, and the " Reloading because of stack merge or communication failure" error message appears.
I saw this issue at "Cisco wiki" but the resolution in that page is just "Open a case with TAC". Because of the reasion is H/W Problem.
Is The resolution only one ? anything else? The 3750 does not use Stack.It is just stand alone. So i think it has other resolution as "disabling Stack" or another one. How about my opinion ? Is the Resolution only "Open a Case with TAC"

what IOS ver can I upgrade to that is not already deferred?
Switch 2 has an interface configured in RSU Standby.Switch 3 has an interface configured in RSU active. The upgrading sequence is : Switch 2, Switch 1, Switch3.The aim of the test is to prove that there is no loss of IP connectivity throught the RSU process.During the RSU process, there are ping between all the computers.
IOS starting version : 15.0-1.SE3
IOS upgrading version (with OVERWRITE) : 15.0-1.SE3 (same version)
1rst step : Switch 2 reboot and come back master but isolated from original stack (switch 1 and 3)
2nd step : Switch 1 reboot, and come back with switch 2 into the upgrading stack.
Issue : at this step :
- Switch 1 put its interface (IP 192.168.5.254) up :
- Switch 3 has not reboot and still has its interface (IP 192.168.5.254) up
=> we have some OSPF adjencies and mac flapping issues : switch 1 and 3 are trying to mount there OSPF adjencies on the same IP. We loss our IP connectivity since step 3 is not over.
3rd step : Switch 3 reboot and come back up in the upgrading stack. The IP connectivity is back, and the RSU process is done.Is that a normal behaviour ?How can we avoid to loose IP connectivity during RSU process ?
Zero downtime 3750 stack upgrade?
View 1 Replies View RelatedI was just curious about something with upgrading a 2960s stack.
To copy the image to the switches in the stack I use: Switch# archive download-sw tftp://x.x.x.x/filename
Does this also set the image as the boot image or do I still need to issue the boot system flash command?
can I just issue this command on the master switch and reload and the new config will be pushed to the rest of the switches?

I want to run rolling-stack upgrades on several stacks containing Catalyst 3750X-switches. I have done as follows: Configured the redundant uplinks as active and stand-by.Started to upgrade by using archive download-sw /rolling-stack-upgrade /overwrite /reload The upgrade starts as expected BUT switch number 2 in the stack is reloaded BEFORE switch 1 is finnished, the result is of course downtime for the stack. The documentation says something about the command "boot time", but what is this command doing? The default seems to be 7 minutes, it this parameter the time the upgrade-process waits before booting the next switch in the stack? I would expect that switch number 2 is reloaded when switch 1 is up again after reload, and not after an absolute number of minutes, is the rolling-stack-upgrade not working this way ?
View 4 Replies View RelatedI have 2 Catalyst 2960S-switches configured in a stack. The uplink is configured as a cross-stack etherchannel. Now I want to upgrade the stack with a minimum of downtime for the connected hosts. The hosts are connected to the stack via cross-stack etherchannels. So my question is: How can I upgrade the stack and reboot the members with a minimum of downtime? If I use the archive download-sw command with the /reload-option, the stack is reloaded and the result will be downtime for the hosts while th stack is reloading. Is it possible to upgrade the stack and then reboot the members one by one in a controlled manner?
View 8 Replies View RelatedThis feature doesn't work as advertised on the Release Notes and other documentation. After 12 hrs of lab work and a tlwo day support call to TAC, they finally came back to me that:
IOS Upgrade works well if you use the command force-reload, without force-reload, it won't work. --"of course with this command the complete stack will go down and the purpose of RSU will not serve"
Then they pointed me to a bug that I could not find in the bug tracker unless I searched by the bug ID number ?? CSCua78897
Unfortunately this bug has a closed status and is not slated to be fixed ?
Are there issues with the auto upgrade feature for 3750X stacks, either historically or currently?
Some people prefer to upgrade switch stacks manually by disconnectiong the stack cables and uprading code on each switch.
I've done the manual procedure in the past and have not tried the auto upgrade (I have the procedure for the auto upgrade).

Actually, all the 4 switches are at the firmware version 12.2(50) SE1 "IPBase" and I want to upgrade them to 12.2(55)SE5 IPBase. According to the release notes, all the switches in my stack are supported.
To upgrade the firmware, I use the command "archive download-sw /imageonly /overwrite tftp://IP_Address/c3750-ipbaselmk9-tar.122-55.SE5.tar" The firmware gets uploaded correctly but then I get the error message "There is insufficient space in flash: to install the required image. Clean up some old images, and try again."
When I do a "show flash", I see that the switch has 5650944 bytes free of 15998976 bytes.
How can i upgrade my switches? Is there an error in my command which I use? Do I need to add an other option?
The problem is, the switches are located in a branch office and there is no direct access to them. Everything must be done remotely.
