later that by mistake i typed delete /force /recursive flash:now, I am unable to load new IOS error loading "flash:c3750e-universalk9-mz.122-55.SE5.bin" Interrupt within 5 seconds to abort boot process.Boot process failed...
I have a cisco 3750 swicth which i want to load a new ios to but unfortunately there's no enough space on the flash. This means that i need to backup the cureent (old) ios to my tftp server but the command keeps failing. It always gives 'No such file or directory' error .The free space on the flash is 8mb and my new ios is about 11mb.I also went inside the directory where the old is and inputed the same copy command but to no avail.Below are some of the command failure on the swicth:
I want to upgrade IOS for my production core 3750 switch. Below is Show version/fash output. I have IOS image "c3750-ipservicesk9-mz.122-55.SE7", need to confirm below concerns:-
1-As this is stackable switch do i need to upgrade on all Switch..i can see there are 3 flash while doing show flash? 2-Is above IOS image support with my switch? do i able to enable ssh? 3-is flash memory is enough to succefully upgrade IOS? 4-Any other point which i should keep in mind before upgrading..any special feature which this IOS wont support.
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.
I am planning to upgrade the current core switch(3750) to 6509 series switch. Since we have a production network running we have to plan for an online core switch upgrade.
The stackwise marketing info states that when a failed member is replaced with a new switch the replacement switch "gets the exact configuration of the old device". I would figure it takes a little more than just disconnecting and connecting a new switch in the same spot on the stack. doing this with 3750 family switches? What are the steps to prepare the stack for a new member? what steps need to be taken on the replacement switch before insertion into the stack to make sure it gets configured like the unit it was replacing?
i have an issue to connect a trunk between cisco switch and extreme switch i have many vlans that i want to cross via a link between cisco 3750 switch and a Extreme Alpine 3800 switch
I have two 3750-X configured to be a stack and I am planning to re-rack these somewhere else. What I would like to know is what are the effects of having the master switch itself lose power? Does it immediately just make the member take over master (there should be no election since there are only 2 switches??) and there would be no loss of connectivity?
I have a situation where I have a 3750-X stack bought with the 350w power supplies. A "show Inv" lists model as "WS-C3750X-48T-L". I now need to suport POE in that space. Is it possible to add in a 1100W power supply and have the switch support POE or is the chassis different and cannot support POE, no matter what PS is installed?
We are going to upgrade our IOS on our WS-C2960G-48TC-L. But before we do that i want to ask whats the best IOS release to choose. Why we want to upgrade is because our switch software now don't support ssh just telnet access
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?
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;
I want to upgrade the IOS version of 3750 48PS switches. these stacks are located on different building some of the them having 2 members and some have 3 members in a stack.step by step to upgrade the IOS of these switches.
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.
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 ?
I have read that the 3750-X supports upgrading with minimal traffic lost with RSU feature, on the configuration guide the scnario is with the end user connected to the 3750-X stack with LACP and the uplinks to the network running STP, one uplink is forwarding and the other is blocked. I have the same scenario but for the network uplink i also have LACP. When i tried to configured the RU stanby one of the uplink LACP the switch gives an error.
I wanted to know if there is a way of upgrading the IOS on a stack of 6 - 8 3750's with minimal impact at reload. Is there a way to reload one member at a time?
I have been looking into this for a while and I can't seem to figure out why my 2nd vlan is not able to connect properly to the net.
My switch has 12 ports where my devices connects directly, they are all on Vlan 1 and they all work perfectly. on Port 12 I have a dlink router that is connected to a cable modem. the dlink router has an Ip address of 192.168.0.20
I created a second vlan (vlan2) and enabled dhcp relay on it. then I assigned port 9 on the switch to (vlan2)my laptop which is connected to port 9 seems to get an ip address fine and able to ping only some devices on my network (vlan1) and is not able to go out to the internet. I think it has to do with the routes. [code]
I have the task of replicating the router config on a 3825 router on a 3750 switch. Reason is we are taking out the router and replacing it with the switch to make use of the router for other functions.
Below is main part of the router config:
! ip source-route ip cef ! ! multilink bundle-name authenticated ! license udi pid CISCO3825 sn FCZxxxxxxx ! vlan internal allocation policy ascending
[code].....
The 3750 switch I have runs C3750E-UNIVERSALK9-M, Version 12.2(55)SE3 on a LAN BASE license.
The first thing I have done is to order for a license upgrade to IP BASE which would give the support for OSPF routing.I do not see much of an issue with the Interface configs, however, I am not too sure about replicating the routing config on the switch.
My question is can I run the commands as shown for the OSPF routing on the switch? If not, can I get suggestions on how best to set this up on the switch?

I'm running into what seems a basic ip routing config problem with a Catalyst 3750 (IP Base) switch. I have several VLANS configured on the switch with IP routing enabled, and the switch is connected to the inside interace of a new ASA 5520 as follows:
ASA5520 IP (Default gateway): 192.168.1.1Switchport Gi1/0/1 is configured as a routed port, IP address 192.168.1.3 255.255.255.0Example VLAN is VLAN 100, IP address 192.168.100.1 255.255.252.0 From the switch CLI, I can ping all VLAN addresses, as well as the ASA5520, and the client laptop I'm testing with from VLAN 100.
From the client laptop on VLAN 100, I can ping all switch interface and VLAN addresses (inter-VLAN routing is working), including 192.168.1.3, but I CANNOT ping the default gateway at 192.168.1.1.
Here is the relevant configuration information on the 3750:
! no aaa new-model switch 1 provision ws-c3750x-24 system mtu routing 1500
configure qos in Cisco 3750 switch.I have configured below template and applied on the vlan interface.But i am getting the hit on the access list but I am not able to get hit on the class map.
I had a bad expirience with Switch 3750-X. Because of an auditing security processess, my customer ran a software called "Nessus" to do a scanning of vulnerability on the network. When this software is point to switch, the process of the switch will next to 100% and reset. The software only do a listening on the ports to see what ports are opened and the switch should not reset because this. Bellow is the log os switch on the moment of test; we note that the processess 'HTTP' rise moments before the switch reset. I disable the HTTP service on switch but the problem persist. The test was made only one machine connected to switch.
We have three Cisco 3750 - 48port POE -LAN switches and i am trying to see if there are any issues when we stack POE and Non-POE type of switches.Aslo looking for information on the advanatage and disadvantage the stacking can provide on a Cisco 3750 48port.
The question is: Will a 3750 switch route Jumbo frame sizes (e.g. 9000 MTU)?
We know that we can change the System MTU to 9000, and someone on a previous thread said that we can change the Routing MTU to 9000 as well, although I couldn't figure out how to do that. However, regardless of how we configure the System MTU and Routing MTU, I don't think we're able to adjust the MTU on L3 VLAN interfaces, so if we want to actually "route" between VLANs on the switch, we're limited to 1500 MTU.
Our situation is that we have a customer connecting to our 3750 switch, and this customer wants to use Jumbo frames. The customer connects to our 3750 switch via their own VLAN, with their own L3 VLAN interface configured on the switch. The customer will point their traffic towards the L3 VLAN interface, then we want to route them onto another VLAN, via a different L3 VLAN interface, before forwarding their traffic. Because of the limitations noted above, specificially regarding the routing between these VLANs via L3 interfaces, I do not think we'll be able to support 9000 MTU frames on this 3750 switch. I think the L3 VLAN interfaces will limit us to 1500 MTU, regardless of what we configured via the global System MTU and Routing MTU settings.
How do you properly remove the QOS queues and configs from the switch.A was using auto qos which created a whole mess of qos configs on my running-config. I did "no mls qos" in conf term but that did not remove the queues.
i want to remove an access layer 3750 48 POE master switch and replace with a new 3750 switch in the stack. i want to copy the same configuration to new switch since the old switch is having POE issue and I got replacement of the malfunctioned switch. we have VTP domain is configured in the network...
