Cisco Switching/Routing :: 1000BASE-LX10 - SFP IOS Version Requirement?

Dec 31, 2012

Unforunately I have not been able to find any IOS version requirement for a brand-new 1000BASE-LX10 SFP (MGBLH1) in the internet.

The IOS version in use on this stack is:Cisco IOS Software, C3750 Software (C3750-IPBASEK9-M), Version 12.2(55)SE6, RELEASE SOFTWARE (fc1)

[Code]... 

I have searched for this error and beside a third-party module (this is a Cisco SFP) the reason could be that newer IOS version is required. Before I'll request an IOS update to the stack with our internal team, IOS version required for this module to run properly and maybe a link to an overview to lookup such requirements in the future.

Cisco Switching/Routing :: Can 1000BASE-T SFP Work With CAT-6 Cable

Dec 19, 2012

I wonder if Cisco 1000BASE-T SFP can work with CAT-6 cable. I believe it can. But in the Cisco datasheet, it only mentions that “The 1000BASE-T SFP operates on standard Category 5 unshielded twisted pair copper cabling of up to 100m (328 ft) link length”.

Cisco Switching/Routing :: Setup And 1000BASE-T SFP Transceiver Module

Feb 17, 2013

We are looking to purchase some addidtional 48 port swithches for our network. Currently we have the following swtiches setup
 
2 of 3750 POE-24 (These two are stacked and have our servers plugged into them). Currently no SFP modules.
 
3 of 3560 POE-24 (These each have two 1000BASE-T SFP modules in them, with UTP connecting back to the 3750 switches above)
  
We are looking to get 2 of 48 port C2960S-48TS-L switches with two 1000BASE-T SFP modules in each that then will also connect back to the 3750 switches.
 
I had a few of question about this:
 
Will the cisco lite version (rather than the more expensive cisco base software) support the 1000BASE-T SFP modules?
 
The 1000BASE-T SFP modules, are they auto-config? Have you the link for commands we can use, if required?
 
We don't have budget for stack modules, apart from that would you recommend we change anything with the new setup?

Cisco Switching/Routing :: Does CVR-X2-SFP10G Converter Support 1000Base-T SFPs

Jun 14, 2012

[URL]
 
To do that I would like to be able to sniff the traffic traversing our 7k. However, as the 7k doesn't support remote span we have to span locally. This means that I have to connect a pc to the Nexus and sent the span output to that port. However, our 7K is only equipped with N7K-M108X2-12L modules, which contains X2 10G ports. I found the CVR-X2-SFP10G X2 to SFP+ convertor module, but I wonder whether this supports a 1G copper SFP. If it doesn't it would be wasteful to buy one. On the page concerning the module I only found 10G fiber sfp's which are supported.

Cisco Switching/Routing :: 2911 With IOS Version Is 15.1 - Routing Table Not Updating

Oct 2, 2012

I am using Cisco 2911 & IOS version is 15.1. My problem is that after some days (e.g. 15-20 days), the routing table suddenly stops updating & then I have to enter the default route again to make it up. I am using Track 1 to track default route here. After primary link goes down, the Track is also going down but after coming the primary link up, the track is not coming up. So, I have to add the default route again to make it up.

Cisco Switching/Routing :: What Should Be Minimum IOS Version On WS-C6509-E

Sep 26, 2012

what should it be the minimum IOS version that I require on my WS-C6509-E equipments to support "logging origin-id" command?

Cisco documentation says that this command was introduced in 12.2(15)T, and integrated into 12.2(33)SXH.
BUT my Cisco switches have 12.2(33)SXH5 IOS version......and they do not support "logging origin-id".

They seems to be coming on regular basis, repeating every minute. I've tried Google and the most relevant info I can find is this {URL}. But it says "Upgrade software to IOS version 12.2(52)SG or later OR 12.2(50)SG4 or later. ".  I'm already running 12.2(54), so why does this 3 line repeatedly show up in the log every minute.

Cisco Switching/Routing :: 3750 Stack - Recommended IOS Version?

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 ?

Cisco Switching/Routing :: Why 2950 Model Not Running EI Version Of IOS

Jun 3, 2012

I have several older 2950's running on my network. This one in particular became of interest to me because I couldn't set up SSH on it or enable any QoS features on it, so I did some research. What I found was there are basically 2 versions of the IOS, c2950-i6q4l2 or c2950-i6k2l2q4. I also read that the c2950-i6q4l2 IOS versions (like the one in the switch I am referring to) have both the SI and EI feature sets integrated, but the one that gets enabled is entirely dependent upon the switch model you are running it on. Did I understand this correctly? Does the IOS check the hardware on the switch and then decide with feature set to use? If so, what is prohibiting the EI feature set from being enabled on this switch? Is there a way to force the EI feature set to be enabled since it is integrated in this image?
