Cisco Switching/Routing :: Boot 4503-E Switch From Secondary Image?
Sep 13, 2011
We have Cisco 4503-E switch and software version is cat4500e-universal.SPA.03.01.01.SG.150-1.xo1.bin. Now i have uploaded cat4500e-universal.SPA.03.02.01.SG.150-2.SG1.bin IOS-XE software in the switch and want to boot the switch from this image.
I have a cisco 6503 - e series switch which runs c6sup22-psv-mz.121-26.E4.bin. Both superviser engine and MSFC2 card run the same IOS image i guess. In my boot flash their is another image c6msfc2-jsv-mz.121-4.E1. o what is the difference between these images c6msfc2-jsv-mz.121-4.E1 and c6msfc-boot-mz.121-4.E1.
I'm having difficult getting this switch to boot from flash. I do not understand why it is trying to load "b1" from "bs1" instead of something from flash. [code]
after upgrading IOS image to V15 on four 2960S switches: Should I make the boot loader image to match the IOS version?I never thought about this while upgrading IOS image unless there is boot issue. I googled for answer but no luck there...
I checked download section on Cisco.com for C2960S-48FPS-L switch and there is simply no boot loader image..The running boot loader is C2960S-HBOOT-M Version 12.2(55r)SEThe running IOS is: 15.0 (2) SE2.
I am planning to upgrade BootLoader image of 7206VXR router due to booting issue. The router is not booting .But if I go to rommon and give boot it will boot.So I am upgarding my Boot Loader image. Now the Bootloader image and IOS image are exactly same.Can I upgarde the Bootloader image to latest version without upgarding IOS?
We have microsoft servers and other application servers (around 12 in nos) which should have gig connections to the access switch. In turn this access switch will be connected to our distribution switch 4503. Which model of access switch best fits from the below 3 models. It should be cost effective as well.
I have a 5010 that simply won't load any system image. Loads the kickstart image just fine, but once at the Switch(boot)# prompt just give me garbage when I enter "load bootflash:n5000-uk9.5.1.3.N2.1b.bin Restarting system.

Currently we have cisco 4503 switch in one of our location without redundancy which servers below,
300 user (desktop & ip phones) 5 vlans 15 access switches are connected one L3 connectivity.
Actually i want to understand is it really necessary to have 4503 or we can go for 4900 series as we are planning to have redundancy in distribution segment.
Which is the best L3 switch in the above scenario and how to measure the overall performance of the current 4503 switch...
We had a core switch(30 vlans) in our environment and it's noticed that CPU utilization of the core switch is showing high during recent days. I have checked logs and processes, but couldn't find the root cause. The issue found only in the office hourly only(after that the cpu utilization is idle and normal). I have already referred the following link to troubleshoot the issue " [URL]
see the following outputs from the core switch
CPU utilization for five seconds: 99%/0%; one minute: 99%; five minutes: 99% PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process 30 6687557041432420936 466 47.52% 47.10% 45.98% 0 Cat4k Mgmt LoPri 55 30667074884269560256 0 45.36% 45.50% 45.85% 0 IP Input 29 28552856922870089254 0 3.59% 3.50% 3.57% 0 Cat4k Mgmt HiPri

Note: Each Invalid source mac entry in each day from same port (above is the output after clearing logs before 3 days)
My queries regarding the issues are following
1) How can we find root cause regarding the high cpu utilization?
2) Is a single invalid mac address makes the cpu highly utilized for suppressing it?
We have two core switches in our network (Cisco WS-4503). HSRP is working as Active-Standby mode. Recently it has been found that core 1 (which is in active mode) shown high CPU load (60% - 100%). Also found that the below mentioned process takes more CPU. Our network consist of around 30 Vlans. We have already checked for the solution in Cisco website [URL] but couldn't find exact reason. see the below outputs for core 1 switch.

We had a core switch(4503) in our environment and recently we tried to enable syslog in the switch. But the syslog server doesnt receives all the configured level messages from the switch. Following is the only message getting in syslog server after the configuration change in switch.
%SYS-5-CONFIG_I: Configured from console by CWLMS onvty1
(No Traffic related messages like acl deny traffic, spanning tree events etc are getting to syslog server as well as log buffer of the switch)
Following are the logging configuration for the core switch
I am trying to get my workstation to talk to a workstation on a different sub-net through a Cisco 3560 switch. The switch is running the following IOS version: [code]
My primary network is 172.16.0.0 and I am trying to connect to a device on a 192.168.111.0 sub-net. [code]
What would be the best way to get the two workstations talking via the switch?
I cannot boot IOS, when i reload this switch it go to ROMMON. I try to uploand IOS but it still has problem. i think i may wrong some point during i did uploand.
I tried to upgrade IOS from SXI2a to SXI9 in cat 6506 VSS. But the problem is that switch always boot with old IOS. I put the new IOS in sup-bootdisk and slave sup-bootdisk, bootvar is ok with new IOS: [code] Show bootvar is ok but switch always boot with old IOS SXI2a, some bug in IOS sxi2a???, I will try to delete de old IOS from sup bootdisk and try with the new one only.
We've ordered a 4500 core switch and 4948 Server Farm switch for our client, but the switch box does not include a IOS image CD or anything related to IOS image and now the client is asking us why is this item missing as the IOS

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.
I inadvertantly copy the wrong image on to a 35609-X switch and now it gets stuck in a particular mode.
The original image was: c3560e-universalk9-mz.122-53.SE2/c3560e-universalk9-mz.122-53.SE2.bin and I replaced it with: c3560e-universalk9npe-mz.122-55.SE1.bin ( this is what the download site identifies as the image for 3560X-24P-S)
It now sticks at: Front-end Microcode IMG MGR: Programming device 0...rrrrrrwssssssssssssssssssspssssssssssssssss
How can I get back on to delete this image? It ignores the break key.
i have a Cisco 6513 it is used one, i have tryed to boot it but it did not work, it alwayes go to rommon mode and i am not able to know what is the issue,
when it boot i get the below outpot from the switch.

I encountered an issue while trying to boot Catalys WS-C4948-S switch. I power on the switch and I'm able to see the boot messages thourgh serial console cable. But it gets stuck at line "Image text-base: 0x1000000, data-base: ..... ". Also I can enter into rommon mode. I tried to use different kinds of IOS images, tried to boot from tftp but with no luck, the issue is the same.
There are no erros on the screen, it just gets stuck when it enters into IOS, so I don't see the IOS prompt.
I'd like to know if is it possible to load lan base image on Cisco Switch 2960 TC-S. This model (WS-C2960-48TC-S) come with lan lite image and it's the same (phisically) of the 2960 TC-L (lan base image).If I try to upload the lan base image on flash of 2960 TC-S will works?? ..or the switch goes damaged?
I've 3750X switch that isn't loading email. then I went to rommon mode and accidently for "format flash". after that I loaded 15.0 SE2 s/w on it using tftp server but it doesn't boot up with that image. flash had only .bin file after I loaded it from tftp server.
since it wasn't booting up, I did format flash again and thought to load image again from tftp server but now, it doesn't load image from tftp server.
I 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.

There is some way to increase the speed of changing the interface state from DOWN to UP when the cable is connected. I need to configure a port of Cisco 4503 in a way that when a cable is connected the port goes immediatly UP.
A solution can be to keep Cisco interface always UP and I remember that with "no keepalive" command to the interface configuration it was possible. But I tried and nothing happens.
I need to implement over an ethernet link L2 tunnel because I want to isolate another VLANs domain.On the first side I can use the command : sw mo dot1q-tunnel on a new C4503 on the other side I cannot configure the command : sw mo dot1q-tunnel.
the other side is an old C4503 we upgrade the flash with a compact flash to upgrade to a new IOS v15 but the command doesn't exist also.I red the cisco feature navigator feature and I am sure the dot1Q-tunnel is available on my image : cat4500-ipbasek9-mz.150-2.SG.binso I don't know why I can use it.
I'm looking at adding a Cisco 3750-X switch running c3750e-universalk9-mz.122-55.SE1 (IP base license) into a stack of 3750-G switches running c3750-ipbasek9-mz.122-55.SE1.bin Given that the version and feature sets are the same I don't forsee any compatibility issues. Would there be any reason why a universal image wouldn't stack correctly with other switches running the single .bin file?
We deploy 881G routers at our store locations and are planning to upgrade the IOS to 15.2.2. One concern we have is if the router fails to boot to the new image. Is there a way to configure a second boot image as a failover in case the primary boot image does not load? Our current DR plan is to have a laptop on site that we can connect to remotely and setup a console session to manually change the boot file. This can be cumbersome and time consuming, so I'm wondering if the 881 has the ability to have another file loaded if the boot fails.
I've got a 2621XM that has not been used for a while.Completely stripped of any modules and configuration files, the router will continually cycle the startup process without actually booting from the IOS.
The cycle displays the following :
System Bootstrap, Version 12.2(8r) [cmong 8r], RELEASE SOFTWARE (fc1) Copyright (c) 2003 by cisco Systems, Inc.
program load complete, entry point: 0x80008000, size: 0x10034ec
What I've tried:
1) Downloading another IOS image (c2600-is-mz.123-20.bin) via Xmodem and running "confreg 0x2102" from the rommon. All that did is change the last message to "program load complete, entry point: 0x80008000, size: 0x10fa95c"
2) Running the command "boot flash:c2600-is-mz.123-20.bin". If I enable the diagnostics via rommon, the cycle expands to:

[code]....
If it wasn't for the lack of error messages, I would assume it was a hardware issue.If the image was corrupted, I would expect a message indicating that the image couldn't be read.
