Is there a way I can downgrade the firmware on a C3750 v2 switch 24TS-S v07 to 12.2(35) SE5. I have added this new switch to an existing stack but the FW is not compatable. I believe the answer is to upgrade the rest but I cannot afford any down time as they are used to run a CCTV securiy network 24/7. I have included details below to assist with my problem. Switch 4 is the one with a version miss match.

I am confused about some things regarding the different IOS versions and their compatibility with certain switch hardware. I understand the differences between the IPBASE and IPSERVICES ios but am not quite clear as to how you can tell which ios images will work on which Cisco switch model platforms, other than the fact that some switches are designed only to run the IPBASE images and others have advanced hardware to run the advanced images. For instance, if I have a 3750-24TS-E with an IPBASE ios on it, can I load an IPSERVICES ios that came from say a 3750G-24TS-E1U? whether the ios on one platform can be transferred to another?
WS-C3750G-24TS-S1U switch stack with high CPU utilization. 3 switches are stacked and using PBR on that. I am attaching the show cpu process as an attachment.The current template is "desktop routing" template.The selected template optimizes the resources in the switch to support this level of features for 8 routed interfaces and 1024 VLANs.

I have downloaded c3750-ipservicesk9-mz.150-1.SE2.bin and I want to upgrade iOS to this image.
I have a few questions related to this:
1. Is my switch model compatible with this iOS version?
2. Do you recommend the upgrade? Does it bring some notable features?
3. Can I upgrade for free or do I need to buy some license?
4. I also want to upgrade/add the crypto image, can I add crypto for free or some license is required?
5. I have remote access to my switch via the console cable which plugged into machine1. But machine1 is connected to network via the same switch. I am accessing machine1 via SSH, and then the switch via console cable (minicom on CentOS). Is there an upgrade procedure for this kind of situation that also has some fall back (like reboot in X minutes and load the previous image) if the upgrade goes wrong?
I'm troubleshooting interface drops. However the output of the following show commands don't match number of drops. Based on the output, can you find out what is causing the drops? the G1/0/28 is the uplink. Is that just the port got overrun by the traffic?
#show int g1/0/28 GigabitEthernet1/0/28 is up, line protocol is up (connected) Hardware is Gigabit Ethernet, address is 0019.5667.191c (bia 0019.5667.191c)
We have two switches WS-C2960S-24TS-L running in stack with running IOS c2960s-universalk9-mz.122-55.SE3.We have connected two checkpoint devices on Gi1/0/24 and Gi2/0/24 with a simple configuration:
interface range GigabitEthernet1/0/24, gi2/0/24 switchport access vlan x switchport mode access spanning-tree portfast
On the devices log we get the following message:
%SW_MATM-4-MACFLAP_NOTIF: Host 0000.0000.fe21 in vlan x is flapping between port Gi2/0/24 and port Gi1/0/24
The mac-address 0000.0000.fe21 is not found on any checkpoint interface. "Show mac-address int gi1/0/24 or gi2/0/24" does not show the correct mac-address of the checkpoint interface connected to the port, but instead shows 0000.0000.fe21.Is there a bug in the IOS, something wrong with the switch config or does it have something to do with the checkpoint config?
Inter-VLAN applications are slow and same VLAN it is working fine.(i.e.VLAN to VLAN applications and File transfer response was Slow).Switch Model number: WS-C3750G-24TS-S1U
I just received three WS-C2960S-24TS-Land three WS-C3560E-48TD-S switches that i entered the Express Setup on as usual. On two of each type of switch i found the default network that is used to facilitate the Express Setup was 10.0.1.1 and the others used an IP range of 10.0.2.1, i realized this is a small negligible at best difference though i need to provide management with an answer as to why there is a difference between the two and can’t find anything online as to why there is a difference or something that proves there should be a difference. All the documentation I find sounding Express Setup notes that the IP range will be 10.0.1.1 not 10.0.2.1
I need to configure the C3560-24TS, QoS control by IP or subnet.i tried to study books and videos many times but still feel i am not well known about QOs...
I have a situation. I am running two-switch 3750-stack and it crashed this morning. IOS version the switches is: "flash:c3750-ipservicesk9-mz.150-1.SE.bin"

Got 2 of these switch stacked and there is some changes that we are going to undertake which will require us to utilize the whole 8 or 4 (2 from each switch) SFP ports. Just need some adivce on which particular fiber modules should I procure. Does this switch support 10GB of SFP ?
Devices are 3750-24TS Switches, software version is 12.2(55)SE6. how to troubleshoot this issue, I have a pair of ports which are not bundling, no matter what. Is the same behavior with LACP or PAgP. In this outputs I have only the PAgP case.
Output is similar to:
Group Port-channel Protocol Ports ------+-------------+-----------+----------------------------------------------- 12 Po12(SD) PAgP Fa1/0/23(I) Fa1/0/24(I)
we want to record voip telephone?Presently im using wireshark on a laptop to test the rspan session
Here is how it's configured

Ive created the vlan 33 on my core switch and remote SPAN VLANs 133 Core switch is vtp server so i double checked on all switch and vlan 33 and 133 are present When i listen to conversation with wireshark we are only recoding voice of the one who is answering and we don't hear the other person talking?
find out which types of fiber optic that i can connect to three types of switches. the setup that i have that there are:8 access switches (WS-C2960S-24TS-S), in each one there is two SFP connections.2 aggregate switches WS-C3750X-24T-S, in each one there is four SFP connections.and one core switches that has SFP card WS-X4624-SFP-E? Note that the fiber optic that we have coming from filed are multimode.
I have a Cisco C3560G-24TS Switch that has twice now just shut down and the only way to get it back to life is to pull the power and let it boot back up again.
Are there any logs I can check for poss clues as to why this is happening or any other things I can try?
I need 10gigbit uplink for this switch. What are the other devices that i need order along with this device.And what is the diff between X2-10GB-LR= and CVR-X2-SFP.if i take CVR-X2-SFP, in future how can i upgrade from one gig to 10 gig?for current use i need 10gig support required. so what are all the other devices that i need to order.Fiber multimode and distance 15Mt only.
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 Catalyst 4006 switch in production and a spare switch of same model. I have to quickly copy the configuration from production switch to spare switch (both L2 and L3 configurations) How do I do that?
basic question regarding the switchports on the rear of the 2106 controller. How do I configure them for use? I'm using port 1 as my uplink to a trunk port on an ASA and my network traffic to the management interface and guest vlans is all working as expected, but when I plug anything into any of the other ports, they get no addresses from my dhcp server (the ASA). I see nowhere to configure which vlan to tie the ports to or anything. I suppose I'm more used to a catalyst or ASA where I can just pick the ports and vlans (or trunks) I want to attach them to. [code] Again, all of the existing network functionality (private and guest network) is all functioning fine so I'm pretty confident I have the above configured correctly, I just cant make any progress on the WLC ports 2 - 8.
I recently upgraded my router to the Linksys E4200 and setup a 40MHz connection using Channels 44+48 of the 5Ghz spectrum. This works really well on my wife's Lenovo T420 w/Centrino 2x2 and Windows 7. I get over 100Mbit sustained performing CIFS file transfers from my file server. My SSID for 5Ghz is different from 2.4 so I can easily verify which one I'm connected to.
I wanted to do the same on my laptop which is a bit older (Lenovo T410) and only supported 2.4Ghz. So I bought the new Cisco AE2500 802.11n USB adapter and plugged it into a USB2.0 slot (I believe all slots are USB 2.0 on this laptop). I'm using the latest driver from the Cisco website.
Windows XP reports a connection speed of "300Mbit" just like on the my wife's laptop -- but when I do the same CIFS file transfer my transfer rate is "stuck" at 39mbit download (13% of 300) and for uploads I'm getting 16-17% of 300 (approx 48Mbit).
I've tried fiddling with all manner of advanced settings in the Windows driver for the NIC with no avail. No matter what, it's like I'm capped at exactly 39 Mbit.
I tried reviewing the specs of the AE2500 and it says it has two antenna's per band. I assumed this meant it was 2x2? Is this not the case. Is it 1x1? Could this explain it? Or, does it matter which 5Ghz channels I use -- from the AE2500 spec sheet it seemed like it might not support all 5Ghz frequencies?
While 39Mbit is better than the 17-20Mbit I was getting on 802.11g, given how well my wife's laptop works using the Intel NIC it seems something is lacking with the AE2500 or its driver.
Region : Malaysia Model : TL-MR3040 Hardware Version : V1 Firmware Version : TL-MR3040_v1_120822 ISP : Maxis
Using the MR-3040 with the MA180 on Maxis network?The connection seems to come up, it will be usable for awhile and then after that Internet access is not available. Looking at the Status page on the MR-3040 it says 3G is connected. Doing a Diagnostic ping, nothing is reachable.
Purchased E2500 1 week ago. I do not have a problem communicating with the router itself (either hard wired or wireless) but I have been unable to establish a usable internet connection from the router.I live in building that is wired by Restech Services - Ethernet jack in wall - no modem. Connection works just fine if I bypass router and connect directly to PC (windows XP SP3 desktop or windows 7 laptop.),Very difficult to establish any internet connection at all. I have to renew IP address many times or go through re-boot sequence multiple times. Once I get a connection it is unusable. If I attempt to ping a URL (either from PC or from router admin page) it is unable to resolve host. If I ping an IP directly (either from PC or router administrator page) I typically get 60 to 80% packet loss. As noted, if I bypass router and make internet connection directly to PC - no problems - no packet loss.Used Cisco Connect software to set up. On advice of ISP changed MTU from 1500 to 1300. Also registered MAC id with ISP and changed from cloning PC MAC to using the router MAC. Downloaded and installed latest firmware version. Did factory reset and re-configured the whole thing. Double checked and swapped wiring.
