Aug 7, 2012
I own the Cisco switch,2950-24.When power on,it says Crash fault with information showed below: [code] Then I search google.com and found the resolution of upgrating IOS.I push mode button before power.Then I access into the CLI.I checked the files in the flash: and got these. [code]
I have a cisco catalyst 2950 switch (flash:c2950-i6q4l2-mz.121-22.EA1b.bin), in remote location with public IP,how to upgrade ios remotely, by that time running configuration will go?how much down time is required and ?
I am going to upgrade the IOS image on 6509-E SUP 2T from 15.1 to s2t54-adventerprisek9-mz.SPA.150-1.SY3.bin switch and i would like to know whether i would need to upgrade the boot loader image as well.
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 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 an ASA5520 need upgrade new anyconnect client, but the new version is too big, so it's no enough space. I want to delete the ASDM image to free the more space. My question is when I delete the ASDM image,if I could manage the ASA from web browser?
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?
I want to delete the first file c2600-i-mz.122-5d in the flash. Not only delete but also reclaim the memory held by deleted file.I followed a link and i ended up with the c2600-i-mz.122-5d marked as deleted in the flash but the memory was not reclaimed.When I restarted the router, it went to ROMMON mode. This is my understanding when router tried to boot from the flash, It tried to load the first file in the flash. Since the file was marked as deleted therefore Router went to ROMMON mode.Now my question is how could I delete the first file and reclaim the memory on 2600 router?
Working on a C4948-10g switch. Trying to reset switch to factory settings. I have ran the Switch#>wr erase, command but the vlan's are still in the config. If you do a show vlan it still shows all the vlan text. I have tried the Switch#>delete vlan.dat, doesn't work. Tried Switch#>delete nvram:vlan.dat, doesn't work. Tried Switch#>erase startup-config, doesn't work. How can I get rid of the vlan's?
i have a few 3550's at the moment and when i use the delete /force /recursive flash:html command it just throws back "permission denied" this seems pretty common on the 3550 but i have never had an issue on the 2950, 3550, 2960, 3560 just the 3550.
Can any give me the command for recursive deleting on the 3550 in the console i.e. hyper terminal?
I want upgrade IOS on my 7206VXR from 12.4(12c) to 15.1(4)M5 , but the CF card only 64M.
-NAME: "disk2", DESCR: "64MB Compact Flash Disk for NPE-G1" -Router#show bootvar
BOOT variable = disk2:c7200-jk9s-mz.124-12c.bin,15.1(4)M5 is almost 40M. So there is not enough space.I want to ask is it ok if I upgrade with normal precedure , With the command " copy tftp: disk2: " ?Does the router will automatically delete the older IOS first and then copy into the new one ? Or Is there something I should pay attention first ?

I have a catalyst 2950 ver. 12.1 EA(48 SI) and intend to upgrade to the latest version of the software. But there have been Four different IOS IMAGE releases before the latest one of 2008. My question is, DO I HAVE TO UPGRADE THE PREVIOUS FOUR RELEASES BEFORE THE NEW ONE OR WILL UPGRADING DIRECTLY TO THE 2008 NEW IMAGE Suffice?
Is there a way to get more messages out of a 2950 set to syslog? I've turned every logging option I can find to DEBUG, but all I get in my syslog are LinkUp/Down messages and "Configured from console by console". I'd love to see more information such as configuration changes, or even someone attempting to set up DTP on a switchport set to access mode.
One of my wi-fi site having 2nos cisco 2950 switchs. in that network some D-link unmanageble swithes also there and access points also connected to cisco switchs and D-link switchs.after one or two days i am not able to connect the wi-fi, then i need to restart the access point then only wi-fi is working fine.I upgraded the latest ios also.I connected some access points to the cisco switch ports, those ports are showing crc error messages like below.

I have a server windows 2008 that I would like to have a nic teaming configuration, the server has two nics, each nic is connected to a different switch. One is connected to cisco 2960 and the other is connected to cisco 2950. I have read here in forums about nic teaming but using the same switch. I have not found using different switch. Is this possible?
I have a problem with an etherchannel between a cisco 2950 and a couple of catalyst 4506. The cisco 2950 is connect via an etherchannel to the catalyst 4506A. The channel consist of two port on both side and is in trunk mode, encapsulation dot1q.Now i have the necessity to connect the 2950 to the other catalyst, 4506B. So, i copy the same configuration on the 4506B, but when I unplug the two rj45 cables from the catalyst 4506A to plug them in the 4506B the etherchannel doesn't go up in any way.
I have 10 2950 switches on my network that support only 64 vlans on each one. I actualy have requrement to cleate around 100 vlans acros them, can I switch off vtp and create required vlans manualy? I will have more or less following set up:
c2950-i6q4l2-mz.121-22.EA10a.bin is the image name of the 2950 switch i have in my office. what is the meaning of " i6q4l2 "? I saw some IOS like IP base, adv-security. but i didn't see anything like this before.
What are the security issues in connecting a notebook to a console of the 2950 switch? Can virus or Trojan enter into a switch during configuration session? If the answer is yes, what precautions must I take to prevent such case?
We are in a process to replace our old end of life switches( mostly Cisco 2950's) with some new offerings from cisco. Attached is our current network diagram. Anny merit of using Cisco Nexus switches in this design and also what will be the benifit in doing so. Again I am asking about the specific benefits which I will get in my Network not general benifits of nexus.
