Cisco WAN :: 3750X Stack-power Feature / No Shut On Ports?
Aug 23, 2011
I have a stack of five 3750X's connected in a single stack with the stackwise cables. Within this one stack, I created two power stacks, one power stack has 3 switches and the other has two switches. In each of the separate power stacks, one power stack port on a switch shows "shut", so the power stacks are not operating in a full ring. Is there a way to do a "no shut" on those stacks ports that are shut? IOS is 12.2(55)SE1
I have 3 switches in my 3750 X stack. I am getting the following error in the logs: %PLATFORM_STACKPOWER-4-PRIO_CONFLICT: Switch 1's power stack has conflicting power priorities. Not sure what I should do next. Below is my Stack-power configuration:
Power stack name: Powerstack-1 Stack mode: Power sharing Stack topology: Ring Switch 1: Power budget: 735 Low port priority value: 20 High port priority value: 10 Switch priority value: 2 Port 1 status: Connected Port 2 status: Connected Neighbor on port 1: c464.1308.7900 Neighbor on port 2: e8b7.4827.e680 Switch 3: Power budget: 729 Low port priority value: 22 High port priority value: 13 Switch priority value: 4 Port 1 status: Connected Port 2 status: Connected Neighbor on port 1: 2894.0fd9.9f00 Neighbor on port 2: 2894.0fd8.e200 Switch 2: Power budget: 690 Low port priority value: 21 High port priority value: 12 Switch priority value: 3 Port 1 status: Connected Port 2 status: Connected Neighbor on port 1: 2894.0fd8.e200 Neighbor on port 2: c464.1308.7900
Each switch has its own 715W power supply in it and all check out OK.
After stacking two 3750X switches, with four equal power-supply's, with StackWise and PowerStack , still got the next message every few hours %PLATFORM_ENV-1-FRU_PS_ACCESS: FRU Power Supply is not responding (gn4m-rt1p08-04-2)( note that the message revers to the second switch in the stack ) although the stackwise and powerstack on the switches is oke and are working correctly. !
Config : Stack-power in power-sharing mode/strict With CLI on the switch : All the power supply's and stack-power details, prio look OK.
Only: LMS prime /inventory/cisco-view/configure/power supply status result : some power supply's are marked as disabled.with the command > power supply 2 slot a off/on I manage to get the status back to "normal", but after a few hours some power supply's are again marked as "disabled".
I have two WS-C3750X-48PF-S in stack, but every one has just one power supply. In the package of the switches is included one stack power supply cable.does it make sense to use stack power cable if every switch has just one power supply ??
In a stand alone 3750x switch configuration, can the secondary power supply only act as a redundant power supply (active/standby), or can it become a "pool" of power similar to power sharing mode for StackPower (somewhat active/active)? I understand there is no stack involved here but I'm curious if this functionality is possible.
Just up-graded my OS to Win 7 Pro and I installed the adapter with no problems.. The problem starts when trying to shut sown Win 7, when I try to power off the system, the little blue light flickers about 1/2 dozen times then goes Steady Blue and stays that way till it shuts off..I have to manully take it out of the USB port each time I shut down my PC or it will get really hot and Probably burn up. I have tried all the power options and that does nothing...This did not happen when I was running XP service pack 3 32 bit.

I have a cisco 3750v2-48TS connected to a cisco 3750v2-48PS in a stack. The stack ports show up as down/down in the stack.Is there a limitation as to if they can be connected.? I mean can we have a PoE and a non PoE in the stack?
I have cisco catalyst 2960S switch. In this switch I have created the vlan 10 with member ports Gig 1/0/1, Gig 1/0/2 and Gig 1/0/3. What I want to configure is as follows.
- If any one of the port of this vlan 10 is turned down, then I want to shutdown entire van
- If Gi1/0/1 is turned down, then I want to shut down Gi1/0/2.
PC---2960---3750(One Routed Port and All Switched Port)------------------------ 3750(One Routed Port and All Switched Port)-----2960------Internet
I have many Vlans on left side of image , Right Side of Image is having internet connection via Modem, and local connectivity between VLAN works fine but Other Vlans Except Vlan1 is able to Access Internet.Note that 3750X did not have NAT Feature ,How should I able to get Internet on Other Vlans (10,20)
we're upgrading over 40 of our 3550/3560 switches to the 3560x platform - what I have noticed is that we get quite a few PoE issues when migrating the site - for instance, 90 - 95% of the site's Cisco's phones will come up but not all of them - the best way to resolve that issue is to identify the ports that haven't came up and then shut - wait 10 secs and no shut.
Is there a way to configure a switch (3550, 3560,3750) to disable a switch port if it has not been used for a specified time period such as weeks or months. Say you want the switch to disable switch ports that have been "abandoned".
I have been looking to find out the list of features that the IP Base IOS has for the 3750X series switch. What would be ideal is a comparable list but essentially I need to know which of the LAN Base/IP Base/IP Services has SSH functionality.
Full feature set for IP Base with the 3750x.I just wanted to verify that I could create a routed port, turn ip routing on, and create static routes as well as a default route. From what I can find, there shouldn't be a problem with this on the IP Base Feature Set, I just wanted to verify. Or any link for the Features of IP Base on the 3750x.
What is supported in terms of running a mixed feature set in a Cisco 3750 switch stack.We are looking at setting up a stack consisting of 5 x 3750V2 and 2 x 3750G. Due to a requirement for full EIGRP we need the IP Services feature set. Is it a supported configuration to run with 2 or 3 switches running the IP Services feature set as stack masters and the others running IP Base? I understand that if stack master priorities were set these switches with the higher feature set could manage the stack and offer IP Services accross the stack. If we were to lose all of the switches running IP Services the stack would drop back to IP Base.I am looking for guidance as to if this is a supported configuration and not in breach of licensing? Is this likely to cause any problem other than above now and for future IOS releases?
I have a cisco 1811 with 2 isp. i want to shut down an interface when a IP is not responding anymore and to “no shut” when the ip is back online. Here what I make: the interface go shut when 85.14.47.40 not respond but never came up when 85.14.47.40 is back online.

Does the power save feature of the SG 102-24 can be disabled somehow ? Our college just purchased 24 of these switches. We are having a problem with the switches affecting some of our monitoring software (Vision from Nettop).Basically, the client pc's become invisible to the master station. I believe this is due to the ports doing an automatic shutoff.I know these switches are unmanaged, but I'm hoping they at least have some form of configurability. Right now our only option is to have an instructor cycle the power of the switch to get the client pc's visible again.
I'm trying to review a QoS setup, and I'd like to make sure I fully understand the current setup before I change anything. I'm seeing output drops on two different queue-thresholds, but not sure how packets are making it to one of the queues.
Switch Version CORE#show ver Cisco IOS Software, C3750E Software (C3750E-UNIVERSALK9-M), Version 15.0(2)SE, RELEASE SOFTWARE (fc1) System image file is "flash:/c3750e-universalk9-mz.150-2.SE/c3750e-universalk9-mz.150-2.SE.bin" cisco WS-C3750X-24 (PowerPC405) processor (revision A0) with 262144K bytes of memory. Switch Ports Model SW Version(code)
I can find queue4-threshold3 in the mappings, but how are packets getting mapped to queue2-threshold1? The priority queue is disabled for this interface, so I'm not sure how this queue is dropping packets, according to the maps nothing is mapped to 02-01.
This 3750X stack (3 members) has some 100% cpu spikes. Is this bad enough to start tracking down the cause(s) or is this somewhat typical and not a reason for concern? I just took this reading. How can you detemine when the 100% and 80% spikes occurred?
I recently created a stack using (2) 3750x switches. I have three vlans on the stack (1,105,241) Vlan 105 is configured on 6509 core switches with multicasting and are connected to the stack via gigabit fiber. It is working well with clients on the Master or SW1, however clients on SW2 do not participate in multicasting Any client pc that is connected to SW2 vlan 105 does not show up in the "sh ip igmp snooping group" command. I can statically assign a client on SW2 to the mcast groups but but they fail to register on their own. I can take the cable connection from SW2 and plug it into an SW1 Vlan 105 port and it immediately becomes a member of the groups. I can then connect it back to the SW2 port and it disappears from the group membership. IGMP and PIM are configured with the defaults.
Seeing very high CPU on one of our 3750X stacks. Usally its around 30% but recently its 70, 80, 90 or maxed at 100% during the main day.IOS version c3750e-universalk9-mz.122-55.SE1.bin.Has a ten gig uplink connected to a nexus 7k and another ten gig connected to another 7k. Running Layer 3 and EIGRP on the 3750X.Is this normal for the CPU?

Recently, we had a 3750X stack of 9 switches reload with no information as to why. Our syslog server received no spurious errors regarding the cause nor did the location lose power. The UPS to which it is attached logged no glitches relating to power. Other cisco devices (router, other switches not in the stack) did not reload. No one was in the MDF during this time. We self insure these line of switches so a TAC case is not an option at this time. Any forensic tools that I could try in an attempt to narrow down the cause.
I'm trying to use LMS to upgrade a stack of switches that have 1 or more 3750x's and other 3750's. In Software Distribution, if I choose Distrube to devices, basic, it finds the x switch, which is the master but says the others are not candidates. I don't see a place where I can tell it it is a mixes stack and choose multiple IOS's.
I have a stack of three 3750X-24P-S switches. Each switch has two PSU's.If I do a SH INVENT, switch 2 only lists Power Supply 0
If, however I do a SESS 2 onto the second switch in the stack and then do a SH INVENT, it shows both power supplies. Is it anything to be concerned about?
Switch 2 has an interface configured in RSU Standby.Switch 3 has an interface configured in RSU active. The upgrading sequence is : Switch 2, Switch 1, Switch3.The aim of the test is to prove that there is no loss of IP connectivity throught the RSU process.During the RSU process, there are ping between all the computers.
IOS starting version : 15.0-1.SE3 IOS upgrading version (with OVERWRITE) : 15.0-1.SE3 (same version)
1rst step : Switch 2 reboot and come back master but isolated from original stack (switch 1 and 3)
2nd step : Switch 1 reboot, and come back with switch 2 into the upgrading stack.
Issue : at this step :
- Switch 1 put its interface (IP 192.168.5.254) up :
- Switch 3 has not reboot and still has its interface (IP 192.168.5.254) up
=> we have some OSPF adjencies and mac flapping issues : switch 1 and 3 are trying to mount there OSPF adjencies on the same IP. We loss our IP connectivity since step 3 is not over.
3rd step : Switch 3 reboot and come back up in the upgrading stack. The IP connectivity is back, and the RSU process is done.Is that a normal behaviour ?How can we avoid to loose IP connectivity during RSU process ?
I've a situation where I need to add a new 3750x to a existing stack of 3750. [code] When I tried to stack them together, I get a version mismatch error. Is this because of the difference in SW Image? What are my options next ? My ultimate goal is to make the new switch stack correctly with the exisitng switches.
IOS upgrade tried on the stack of 2XWS-C3750X-24T-S , Upgrade was tried to support WCCP on the platform. Current version is Cisco IOS Software, C3750E Software (C3750E-UNIVERSALK9-M), Version 12.2(58)SE1, Not able find any IP Plus ios in the site ? Only available are IP base and Universal K9 , Tried upgrading to c3750e-universalk9-tar.122-58.SE2.tar by using stack upgrade method as per document [URL]
Upgrade fails with error :
%Error opening flash:update/info (No such file or directory) ERROR: Image is not a valid IOS image archive.
Why current ios is not supporting WCCP , I hope it is there in the featureset. ( tried "sdm prefer routing" but no success) Does c3750e-universalk9-tar.122-58.SE2.tar will give me wccp support ? What is the issue with my upgrade and how do I do a successfull upgrade ?
We recently configured a stack of four 48 port 3750-x switches . We are noticing high CPU usage. "Hulc LED process" seems pretty high. This has coincided with VMware servers getting slow and non-responsive at times, perhaps a coincidence, not sure. Below I provided some outputs about how to diagnose it.
if I read the Datasheet of Catalyst 3750X-Series-Switches it is possible to connect a new X-Switch to an existing and old Catalyst 3750-Series Stack.What kind of requirements are needed? Only same IOS-Version in the hole Stack and if possible same Feature-Set? .... like in a normal NOT mixed Stack?
