Cisco Switching/Routing :: Error Reading When Upgrading The IOS In Cat-3750
Nov 9, 2011
I'm having some problems when upgrading the IOS of my Catalyst 3750 switch through a tftp server. I've been surfing the net and found that there seems to be a problem when the image file is larger than 16M but this is not my case.I erased the flash to be sure that there was enough memory space to upload the image but didnt work.I also tried with archive download-sw /overwrite command and using a ftp server but the problem is the always the same: [code]To make sure it was not a problem of my computer or tftp server, I tried with a different computer and with a different tftp server but the same happen. I also tried with a 3750V2 and still the same. Even when trying to backup the current IOS to my computer, I got "error writing".
Then, I have tried to do the same with a different model of switch, a WS-C3560-48PS and it works perfect.I still need to try using Xmodem but Xmodem takes ages to finalize the process.

we have two core swiches 6506 and around 55 cat 3550 switches. currently we are on the process of replacing the cat 3550 switches to 3750 switches.We need 10/1000/1000 speed, ip base image with upgrade options. Our up links from cat 3550s(sfps) are single mode and dual mode fiber mode with 1 gbps ports on core switch.
At present we are not upgrading to 10 gb modules on core. Spread over 15 floors each floor needs 2 up links(single mode , and dual mode). since cat 3750 sfps are smaller in size existing gibics cannot be used. Looking for the best option of cat 3750 switches with 1 gb up links which can be upgraded to 10 gb later when we replace the modle on core. Requirements:
1- Cat 3750 switches 55 in no with sfps for 1 gb up link (dual mode fiber and single mode fiber)
2- stacking option
3- 10/100/1000 speed
4- ip base image upgradable to ip service image
5- ipv6 compatibaility. Network is spread over 15 floors so from each floor we need two sfp up links 1 gbps using dual mode and single mode
-6-Should be upgradable to 10 gb in future when we upgrade the core modules
Or is it better to go for 10 gb module in core as well as edge switches ? if so what should be the modules?

I just need a little refreshing on upgrading a stack of 3750's. This stack only has 2 switches: [code]
1.) If I remember correctly I simply tftp the IOS to the flash of each switch and then reload the master only?
2.) Can I safely assume these are the 2 flash locations:

is there a document that explains the compatibility of 3750 series that can be stacked together? for example can we stack 3750-x with 3750-v2 without the power sharing? Can we stack a L3 3750 with L2 3750 without upgrading the L2 switch IOS to ip services?

The company I work have finally decided to enter the 21st century and invest in a new telephone system (Interactive Intelligence) to replace the legacy system which has served us well for the past 10 years. The project has only just started and involves upgrading sections of CAT3 cabling to CAT6, replacing Cisco 3550 switches in one area of the building with Cisco 4507 switches and upgrading our Core switches with Cisco Nexus 7010's. The area that concerns me most is enabling the network for qos as I have very little experience with it. At the moment Im trying to read as much documentation as I can on QOS to bring myself up to speed.
The access layer switches will consist of a mixture of Cisco 3750 & 4507 switches connected to Cisco Nexus 7010 switches which will form a collapsed aggregation & core layer.
Basically, how I should approach this daunting task of making sure the network will support VOIP.

Have a small stack of two 3750 routers. Get the following error message every few secounds:
%STACKMGR-4-STACK_LINK_CHANGE: Stack Port 1 Switch 1 has changed to state DOWN
%STACKMGR-4-STACK_LINK_CHANGE: Stack Port 1 Switch 1 has changed to state UP
Now I replaced the stacking cables but no joy. It was ok for an hr or so but then the error messages popped up again. Also random links on this stack back to access layer user switches have been going up and down randomly. So I have decided to take the next step and upgrade the IOS.
Although when I try and copy a new IOS I get the following error:
%Error writing flash:/c3750-ipservicesk9-mz.122-55.SE6.bin (No space left on device)
Seems this image is 130MB while the image that is currently on it is 74MB and free space is 54MB. How do I get the image onto the router? If I delete the current image from flash will that cause the router to stop functioning?
Also I noticed there seems to be more than one flash directory. See below:
copy tftp: ?
flash1: Copy to flash1: file system
flash2: Copy to flash2: file system
flash: Copy to flash: file system
null: Copy to null: file system
nvram: Copy to nvram: file system
running-config Update (merge with) current system configuration
startup-config Copy to startup configuration
system: Copy to system: file system
vb: Copy to vb: file system
The current router image seems to be in flash1 and flash 2 also. Could I delete the image from flash1. Upload it there and then boot the router from flash1?

We have a stack setup with 2 C3750x-12s and 5 C3750x-48p switches. We have two of these stacks. One is working and responding with snmp just fine. Our second one is showing the errors in the logThe only difference i see between the two stacks right now are the sw versions.

We have a number of 3750 stacks used as access layer switches connecting Siemens VOIP phones and then a PC that connects to the phone.
For example if I plug PC A to the phone that connects to port 13 I pick up an IP addressand all works as predicted now if I plug in PC A to any other VOIP phone that connect to another port on the same switch it goes in error disable state ITs like the switch is holding my PC mac address and locks it down with the port which in my case is Gi2/0/13.

I recently upgraded my network to have two 3750x core, one interface on the Cisco is connecting to a Net gear switch via a fiber converter. I am keep getting the vlan flapping error message in my log as below.

After my research i think this is a looping issue but I'm unsure how to address it.

We have ip arp inspection and dhcp snooping enable in couple of 3750 and 3560 switches. Everything works fine, excepted few case that DAI packet rate trigger and errdisable the port. Later on we found out that most of computer that trigger DAI is Windows 7 and especially when they are in sleep mode. Not sure if anyone experiencing it with Windows 7. Also we have it rate limit at 64.

I have a Cisco 1811 with a 4/port Serial Async/Sync (HWIC 4 A/S) and another 2 port A/S serial wic. My router seems to have a problem reading the 4/port card. I did some research and it looks like there shouldn't be a compatibility issue.

The have around 80 staff and I think the current infrastructure is overkill for the size of the company. The current kit is old and they have no GB ethernet ports. They currently have:-
Core Switch:
1x Cisco c6509with a 48 port fast ethernet module (WS-X6248-RJ-45)
and an 8 port fibre module (WS-X6408A-GBIC)
I'm looking to replace this with something with 72 ethernet ports and 8 fibre ports
Access Switches:
2x 3500Replacement needs at least 48 ports and 2 fibre modules each
and 2x 5500Replacement needs at least 72 ports and 2 fibre modules each.

I am in the process of upgrading our network switches and wondering if the .lic file will work with the new software or if I have to rehost for the move to 15.0. Its a remote site and I would like to get some solid info before I pull the trigger.
Also which IOS should I be upgrading to?
c3750e-ipbasek9-mz.150-2.SE.bin
or

I was trying to upgrade an ASA to from 8.2.4 to 8.4.4, and I began receiving the following migration errors (the IP addresses have been changed to protect the innocent):
ERROR: MIGRATION: The following ACE is partially/not migrated to Real IP, as it could result in more permissive policy. Please manually migrate this ACE. permit esp host 1.1.1.1 host 2.2.2.2
I got a TON of these, in fact the migration, and these errors ran for over 24 hours before I gave up, powercycled the unit and forced 8.2.4 to boot through ROMMON. This was a secondary unit, that's why I let it go this long.
What I don't understand is that we do not have anything in the configuration for ESP.

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.
no boot system
boot system flash sup-bootdisk:NEW_IOS.bin
boot system flash sup-bootdisk:OLD_IOS.bin
!
copy run start
reload
I was going through the below cisco document and there are a few more steps as below: Is it necessary?

I am looking at upgrading my 6503-E switch. While I get the chance, I would like all aspects upgraded as I finally have some "downtime". I am running a Sup 720-3B.From what I understand, the boot image is a recovery image (mini IOS) - should the main IOS fail.Where should this be installed, sup-bootflash:/ or bootflash:/ ?,The file is “s72033-boot-mz.122-33.SXI11.bin.”The Boot Loader. My understanding is that Bootloaders are not used in these Sups with a MSFC3? I am not sure why TBH .. but would this be the case ?Rommon can be upgraded. I don’t quite understand if there are two ROMs (SP and RP).

I had a strange problem here after upgrading Cisco 3750X.The upgrading was going smoothly, I copied a newer IOS to the flash from another Cisco 3750X through TFTP, changed the boot image.It took a while do to the microcode upgrading, finally, it started to boot up. But when it completes the boot up, I can't see the normal login prompt, but only some strange codes. From what I can see, it seems some decoding problem, as if I plug or unplug a cable from the switch, the strange code pops up again, like in normal situation, the console tells you that the interface is going up and down.
The original image of the switch: c3750e-universalk9-mz.122-53.SE2.bin
Upgrade to image: c3750e-universalk9-mz.122-55.SE3.bin
However, I don't have any problem to telnet to this switch, as it has correct IP address and login configured before the upgrading. I have reboot the switch for couple of times, reconnect to the serial port still doesn't show me anything.I am wonering has any one has met this situation before? detailed message shown after the boot up. cisco WS-C3750X-48 (PowerPC405) processor (revision A0) with 262144K bytes of memory.

I have a 4510R-E chassis which currently has a single supervisor 5 installed.
We are now looking at upgrading the supervisor to a Sup6. Now the question is this, can I install the Sup6 into the redundant cpu slot and then perform a failover to get the new switch working without any noticable downtime.
I'm not sure what having a Sup V and a Sup 6 in at the same time will do to the backplane.
Otherwise I have to take the switch down and then install the card and software manually.
