Cisco Switching/Routing :: Stacking 3750-X With Universal Image With 3750-G Running BIN Image?

Oct 10, 2011

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?

Cisco Switching/Routing :: Change Of Software Image In 3750 Stack

Nov 9, 2011

End user have had problem with IP phones that are connected  to 3750 stack; many times IP phones lose connection with CallManager and the only way to clear this issue is with clear arp command. DHCP for IP phones is configured in 3750 stack.
At the beginning 3750 stack was set a VTP server, and the others as VTP clients, we detected another VTP server switch so we thought that was the problem, but after removing the issue remains. Finally we set all switch in transparent mode.
Base on this we decided to change the software image  12.2(35)SE1  C3750-ADVIPSERVICESK   --->  122-53.SE2 IPSERVICES I'm going to follow the procedure 3750 Series Switch Stack IOS Upgrade − Automatic .
as it show in the following information there are 4 differents models of 3750 switches, I have already download c3750-ipservicesk9-tar.122-53.SE2.tar for 3750G-24TS.
I have two doubts:

1. There is no problem for using this tar file for all models?

2. I followig command is correct for the change I plann to do ?

Switch#archive download-sw /allow-feature-upgrade /overwrite  tftp://

Cisco Switching/Routing :: Can 2911 Router Work On IOS Other Than Universal Image

Jun 10, 2012

whether a Cisco Router 2911 would work on images other than universal image. This is the question raised by one of our customer. He has 2811 Router where-in he has configured T1/E1 configuration, terminated to Zyxel Modem and working fine. Now he wants to replace this 2811 router with 2911 router. Since the universal image in 2911 router is not working with the present configuration in 2811 router, he wants to know, what options are there for him to configure this in 2911.

Cisco Switching/Routing :: Build Improved Redundancy Into LAN By Stacking Two 3750

May 1, 2012

I plan to build improved redundancy in to my LAN by stacking two 3750s and teaming pairs of NICs on my Dell PowerEdge servers, with each cable of the pair going to a different switch.In my mind this provides redundancy for the NICs and the switches. Does this configuration will work, and also what type of teaming is supported, as I was planning to have one NIC active and one standby, but can I run this configuration with both NICs in the team as active with load balancing?

Cisco Switching/Routing :: 3750 - Running 7 To 9 Switches In One Stack

Aug 6, 2012

Looking for feedback from other organizations that have large 3750 stacks.  I've got one stack of (8) 3750's composed of (6) 3750G's and (2) plain 3750's.  This particular stack is usually unresponsive to SNMP queries and often fails to write config when we make changes.  After a couple tries it will finally go.  Part of my probably here is likely the plain 3750's that always boot faster and come up as the master.  I should manually set the master to one of the G's.  What I'm wondering is who else has 7-9 3750's stacked and are they performing well for SNMP, telnet, etc?  I've got another newer stack of 7 3750E's that I need to add one more switch to.  Need to decide if I want extended downtime to break the stack up or just add the 3750X to make member 8 and hope it performs well.  I have 50+ 3750 stacks working great on our campus.

Cisco Switching/Routing :: 3750-X Stacking Switch By Switch

Nov 18, 2012

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?

Cisco Firewall :: 5505 - Running IOS Image From TFTP?

Mar 22, 2011

I have a Cisco 5505 that had its disk erased (erase:disk0) and now I am trying to load a new image (822 or 813) from a tftp server.
From the ROMMON prompt I have configured the relevant parameters and run a tftp command.
The tftp transfer seems to complete successfully but then it gets stuck on "...loading".
I have tried different versions of IOS and I always experience the same problem, even though, with older versions of IOS (7.x), the device manages to reboot itself but then it crashes with the following error: 

"Error : Uncompression of the image failed. invalid compressed data--format violated"
Could it be an hardware related-issue or a licensing problem maybe? or am I missing anything obvious?
also, with regards to the license: once restored, how do I get my 50 users license back?

Cisco Firewall :: ASA5520 Running 8.3.1 Reboots When Try To Upload New Image

Mar 27, 2011

I'm running a couple of 5520 (with failover configuration) and fw 8.3.1. Everything worked fine until I try to upgrade firewall to new fw version: 8.4.1. [code]
When I try to upload new firrmware or asdm image, ASA,  the appliance reboots during tftp session. I've already tried to upload new images on both appliance, or use CLI either ASDM, but the result is always the same: ASA reboots.

From my point of view, the problem isn't the image but could be the firmware I'm running, becouse using fw. 8.0.1 I was able to upalod asdm 8.3.1, but using fw 8.3.1 I can't upload the same image.

On the datasheet there is a 12.2SG but is an IPBASE with SSH? W/O SSH? UPGRADE SSH? I'm trying to make a comparison between this image and a cat4500e-entservices-mz.150-2.SG2.bin (Advanced Enterprise Services) on the feature navigator to make sure the our customer need this last IOS Upgrade.

Cisco WAN :: High CPU On 3750 Running Routing

May 28, 2012

I have a small network of 4 x 3750s running routing (OSPF) which contain all company firewalls. It bridges internal trusted corporate networks (depots etc) to external untrusted networks (Internet/Datacenter networks). It sees a fairly high level of traffic running through it (it gets forwarded to firewalls at gig speed).OSPF is costed to remove asymetric routing so one 3750 is acting as primary and does most of the work. The 3750s are in area 0, and all other areas are summarised to some degree. However, CPU is running high on the 3750 when looking at the history at times: [code]

although the average is around 26% the 72hour picture would suggest that CPU is running at 100% at times. Is this an imminent concern that needs re-designing, or is this normal behaviour (SPF running for instance) that is manageable?
