Cisco :: LMS 4.2.2 3750x And 3750 Mixed Stack Upgrade

Oct 10, 2012

I'm trying to use LMS to upgrade a stack of switches that have 1 or more 3750x's and other 3750's.  In Software Distribution, if I choose Distrube to devices, basic, it finds the x switch, which is the master but says the others are not candidates.  I don't see a place where I can tell it it is a mixes stack and choose multiple IOS's.

Cisco Switching/Routing :: Upgrading Firmware On Mixed 3750G And 3750X Stack

Jul 3, 2012

I've got a mixed stack as follows:

Switch 1 - 3750X-24P
Switch 2 - 3750G-24TS
Switch 3 - 3750G-24T
 
Running 12.2(53)SE2, IP base.  Now I tried upgrading the firmware on the entire stack to 12.2(55)SE4 and ran into this error:(Command: archive download-sw /imageonly /overwrite /allow-feature-upgrade tftp://10.20.20.13/c3750e-universalk9-tar.122-55.SE4.tar)
 
 Error: The image in the archive which would to used to upgade system number 2 does not support that system type.I haven't as yet removed the "3750G-24TS" switch from the stack and re-tried as yet, however, is the expectation that without the 24TS, the upgrade should work?

Cisco WAN :: Mixed Feature Sets In 3750 Stack - Fully Supported?

Jun 21, 2011

What is supported in terms of running a mixed feature set in a Cisco 3750 switch stack.We are looking at setting up a stack consisting of 5 x 3750V2 and 2 x 3750G. Due to a requirement for full EIGRP we need the IP Services feature set. Is it a supported configuration to run with 2 or 3 switches running the IP Services feature set as stack masters and the others running IP Base? I understand that if stack master priorities were set these switches with the higher feature set could manage the stack and offer IP Services accross the stack. If we were to lose all of the switches running IP Services the stack would drop back to IP Base.I am looking for guidance as to if this is a supported configuration and not in breach of licensing? Is this likely to cause any problem other than above now and for future IOS releases?

I've a situation where I need to add a new 3750x to a existing stack of 3750. [code] When I tried to stack them together, I get a version mismatch error.

Cisco Switching/Routing :: Rolling Stack Upgrade (RSU) With 3750X (IOS 15.0.1-SE3)?

Jun 17, 2012

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 ?

Cisco Switching/Routing :: 3750X Stack Upgrade Failure

Jan 24, 2013

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 ?

Cisco Switching/Routing :: 3750X Rolling Stack Upgrade / Update

Mar 19, 2013

This 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 ?

Cisco Switching/Routing :: 3750X Stack Auto Vs Manual Upgrade

May 8, 2013

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).

Cisco Switching/Routing :: 3750X / 3750 V2 - Upgrade License

Dec 6, 2011

I recently added a 3750X-24P-L into a stack of 3750V2 switches.  I did so by getting the temporary upgrade license from LAN Base to IP Services; I added the switch no problem.  I now have the permanent license and I was wondering if I could install the permanent license without having to remove the switch from the stack.  I tried a license install but that failed.  The switch is not currently the master but I figured I might promote it and then try the install.

Cisco Switching/Routing :: 3750 Stack Switches IOS Upgrade?

Nov 13, 2012

I am trying to do ios upgrade on 5 stacked 3750 switches. All the switches have different model number, so i am wondering which image file i should download. As far as i understand all the stacked switches should have the same IOS, i may be wrong. The switches have the following model numbers and SW images;
  
Switch   Ports  Model              SW Version              SW Image
------   -----  -----              ----------              ----------
     1   28     WS-C3750G-24PS     12.2(35)SE5             C3750-IPSERVICESK9-M
*    2   28     WS-C3750G-24PS     12.2(35)SE5             C3750-IPSERVICESK9-M
     3   52     WS-C3750G-48PS     12.2(35)SE5             C3750-IPSERVICESK9-M
     4   30     WS-C3750E-24PD     12.2(35)SE5             C3750E-UNIVERSAL-M
     5   30     WS-C3750E-24PD     12.2(35)SE5             C3750E-UNIVERSAL-M
 
which image file i should use as they all have different model numbers and Cisco provides different image files for each model.

Cisco Switching/Routing :: Rolling Stack Upgrade Of Catalyst 3750

Apr 1, 2013

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 ?

Cisco Switching/Routing :: 3750 - Firmware Upgrade Of Switch Stack Fails

May 9, 2012

I have a stack of 4 Cisco Switch 3750 (1 x WS-C3750G-24T, 2 x  WS-C3750-48P and 1 x WS-C3750V2-48PS) and I want to do an firmware upgrade of this stack. 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.

Cisco WAN :: Mixed Stack C3750G And C3750X IOS Update Required

Sep 6, 2011

I have running a Stack with two C3750G-24TS-S1U with the IOS c3750-ipbasek9-mz.122-50.SE3.Now I want put a new C3750X-24T-S in the existing stack. I have read this is possible. I have running a other mixed stack with a C3750G-12S and an C3750E-48TD. Its running fine until I want to make an IOS update. The update was done with the CW LMS 3.1. After the automatic update and restart only the C3750E had an new IOS the C3750G doesn't have any IOS. Do I have the same problem with the mixed Stack C3750G and C3750X?Do I have to upgrade the IOS by copying the different IOS Versions ( c3750-ipbasek9-mz.122-50.SE3 / c3750e-ipbasek9-mz.122-50.SE3) to every switch ?

Cisco WAN :: Replacing A Stack Master In 3750 Stack?

Jan 22, 2013

We currently have as our stack master a 24 port Non-PoE that we want to replace with a 48 port Non-PoE. The 48 port switch at one time was provisioned as switch 3 in the stack (not the master). Correct me if I am wrong, but theoretically all I should need to do to get this working is to shut off the existing master so it re-elects a master and then provision the 48 port switch as the new switch one and make sure switch 1 has a high priority?
 
Do I need to write erase the switch that is replacing the current master first?

Cisco Switching/Routing :: QoS On 3750X Stack

May 7, 2013

I'm trying to review a QoS setup, and I'd like to make sure I fully understand the current setup before I change anything. I'm seeing output drops on two different queue-thresholds, but not sure how packets are making it to one of the queues.
 
Switch Version
CORE#show ver
Cisco IOS Software, C3750E Software (C3750E-UNIVERSALK9-M), Version 15.0(2)SE, RELEASE SOFTWARE (fc1)
System image file is "flash:/c3750e-universalk9-mz.150-2.SE/c3750e-universalk9-mz.150-2.SE.bin"
cisco WS-C3750X-24 (PowerPC405) processor (revision A0) with 262144K bytes of memory.
Switch Ports Model              SW Version(code)

I can find queue4-threshold3 in the mappings, but how are packets getting mapped to queue2-threshold1? The priority queue is disabled for this interface, so I'm not sure how this queue is dropping packets, according to the maps nothing is mapped to 02-01.

Cisco Switching/Routing :: Multicast In A 3750x Stack

Jan 31, 2012

I recently created a stack using (2) 3750x switches. I have three vlans on the stack (1,105,241) Vlan 105 is configured on 6509 core switches with multicasting and are connected to the stack via gigabit fiber. It is working well with clients on the Master or SW1, however clients on SW2 do not participate in multicasting Any client pc that is connected to SW2 vlan 105 does not show up in the "sh ip igmp snooping group" command. I can statically assign a client on SW2 to the mcast groups but but they fail to register on their own. I can take the cable connection from SW2 and plug it into an SW1 Vlan 105 port and it immediately becomes a member of the groups. I can then connect it back to the SW2 port and it disappears from the group membership. IGMP and PIM are configured with the defaults.

Cisco WAN :: 3750X Stack Of 9 Switches Reload With No Information

Recently, we had a 3750X stack of 9 switches reload with no information as to why. Our syslog server received no spurious errors regarding the cause nor did the location lose power. The UPS to which it is attached logged no glitches relating to power. Other cisco devices (router, other switches not in the stack) did not reload. No one was in the MDF during this time. We self insure these line of switches so a TAC case is not an option at this time. Any forensic tools that I could try in an attempt to narrow down the cause.
