Dec 19, 2012
We have the following stack configuration:
Switch Ports Model SW Version SW Image------ ----- ----- ---------- ---------- 1 28 WS-C2960S-24TS-L 12.2(55)SE3 C2960S-UNIVERSALK9-M 2 28 WS-C2960S-24TS-L 12.2(55)SE3 C2960S-UNIVERSALK9-M 3 52 WS-C2960S-48TS-L 12.2(55)SE5 C2960S-UNIVERSALK9-M * 4 52 WS-C2960S-48TS-L 12.2(55)SE5 C2960S-UNIVERSALK9-M

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?

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?

I have a got a requirement where a 24 Port Switch should have 4 SFP's and all 4 should be used at a time, So I've chosen " WS-C2960S-24TS-L"
The transeiver should be GLC-LH-SM, so kindly let me no whether I would be able to use all 4 ports at a time or not.

I have a customer with a stack of two switches C2960S-24TS-L that are running 12.2(58)SE2 universal K9, we see that the CPU load increase over time, to 95% and stays there reload solves the problem.the process that akes a lot of CPU is also the SNMP ENGINE, I see that it is running 30 minutes on 95% and then 10 minutes on 35%, this is the only stack were we see this problem. Is there also a SNMP bug in this version ?

Does GLC-GE-100FX is supported on the WS-C2960S-24TD-L. I don't see this switch listed under the compatibiilty matrix.URL,But the datasheet for the 2960S says this:"The Cisco Catalyst 2960-S with SFP+ does not support the GLC-FE-100BX, GLC-FE-100FX, or GLC-FE-100LX."But it provides no reference for the GLC-GE-100FX,The easy answer is, no the 2960S-24TD doesn't support it.

I have a Cisco WS-C2960S-48TD-L with 12.2(55)SE2.This is a standalone switch, not in stack, and with no order it reboots itself looking for a new master election. On logging i have nothing, but connected with console cable i see the following after 2 minutes of not showing anything:
Waiting for Stack Master Election...
...
The switch reboots and:
...
*Mar 1 00:00:12.289: Read env variable - LICENSE_BOOT_LEVEL =
[URL]
After searching online i have no seeing nothing about disable the feature of the stack so i configure the priority for the "switch 1" to 15 and configure it the switches 2, 3 and 4 to no provision, although this switches don´t exist:
SW_ACCESS(config)#switch 1 priority 15
Changing the Switch Priority of Switch Number 1 to 15
Do you want to continue?[confirm]
New Priority has been set successfully
[URL]
With this new configuration the switch has rebooted again.Why on a standalone switch the stack is rebooting my system?Is it any feature to disable the stack?

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

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 facing the following issue. In our environment we have a couple of WS-C2960S-24TS-L configured as stack. These switches are configured as VTP mode transparent.We are running LMS 4.1 and although UserTracking Acquisition works fine for all other switches, it only runs on demand for the above. The user tracking report for these switches shows only the MAC of the connected end hosts, without the respective IP address. The vlan I am interested in is configured on both the gateway (cisco 6509) and the switches, and the subnet is routable.Show arp on the gateway does show the "mac-ip address" binding, so I would have thought that usertracking would have been able to report both IP and MAC.
Why does usertracking only run on demand for the above switches in vtp mode transparent?Why does the UserTracking report show only the MAC and not the IP?Are the above issues related to the vtp mode? I have ruled out any connection to the switch-model, because we have recently installed the same switches in VTP mode client and User Tracking Acquisition works fine for them.

I have configured about 20 of these switches now, and notice in the port listings a TE1/1//1 TE1/1/2 and GI1/1/1 GI1/1/2 uplink port. There are only two uplink SFP+ ports. I now have a reason to install with a 1Gb uplink to the Core. I am using a GLC-LH module at each end. I did configure the TE1/1/1 port for the uplink. Does not work though..Do I need to configure the two GI1/1/1 and 1/1/2 ports for uplink, remove the TE configuration for the uplink to work? Using the UNIVERSAL code with a LANBase license.

I have 8 switches (different models) configured in stack:
Switch Ports Model SW Version SW Image------ ----- ----- ---------- ---------- 1 28 WS-C3750G-24TS-1U 12.2(55)SE C3750-IPSERVICESK9-M 2 26 WS-C3750-24P 12.2(55)SE C3750-IPSERVICESK9-M 3 30 WS-C3750X-24P 12.2(55)SE C3750E-UNIVERSALK9-M 4 30 WS-C3750X-24P 12.2(55)SE C3750E-UNIVERSALK9-M* 5 12 WS-C3750G-12S 12.2(55)SE C3750-IPSERVICESK9-M 6 30 WS-C3750E-24PD 12.2(55)SE C3750E-UNIVERSALK9-M 7 30 WS-C3750E-24PD 12.2(55)SE C3750E-UNIVERSALK9-M 8 30 WS-C3750X-24P 12.2(55)SE C3750E-UNIVERSALK9-M
Now I'm have IOS ver. 12.2(55)SE but from time to time I'm experiencing strange system freezing. It means that all systems connected to the stack are working very, very slow. It hapens ones, sometimes twice a month and takes 5 minutes. I didn't find anything strange in logs (neither on switch nor router). I would like to install other IOS version. Could you recomend me the most stable version for this stack (built from these different models) ?And the secound question: - Is it possible to copy SE1 manualy to every switch and reload one by one manualy. Will they join the stack and work fine after reload or maybe there will be a IOS mismatch ?

I want to connect WS-C2960S-48TD-L switch to WS-X6708-10G-3CXL module in Cisco WS-C6503-E switch. WS-X6708-10G-3CXL is C6K 8 port 10 Gigabit Ethernet module with DFC3CXL which requires X2 module. on the otherhand, WS-C2960S-48TD-L requires SFP+. Now is it possible to interconnect these two switch interfaces if I use LIU in between. or does WS-X6708-10G-3CXL module supports CVR-X2-SFP+ to use SFP+ transceivers.

I'm trying to stack 3750G & 3750X. As discussed in previous threads I am aware of that the version need to match.
Here the switch details:
Switch Ports Model SW Version SW Image

* 1 54 WS-C3750X-48 12.2(55)SE7 C3750E-IPBASEK9-M
I have changed the universal IOS on the 3750X to IP base..but they still wont come up as a stack. On the 3750X I don't see any log entry, on 3750G (major version mismatch).

I have a running setup having 2 Cisco 2960s 24 TS switch with Stack configuration. Now I want to add one more same Cisco switch. My questions are:-
1) How can I do this...(Should follow the same process as I did before.
2) Could I do this without impacting the service. i.e. without rebooting the switch.
3) What should be the connection archiecture as of now since there is two switch so it is connected 1 -1 and 2-2. but for 3 switch should we require to change the connectivity.
