Cisco Switching/Routing :: WS-C3750G-48PS / Unable To Update Boot Path In Stack Switches
Sep 11, 2012
I am in the process of upgrading our stack of 4 switches consist of WS-C3750G-48PS. Upon reading release notes found that there are two versions of release notes 1 day apart, the one 02 Sep 2012 saying that WS-C3750-48PS is not supported in this version. Then in release next day 03 Sep 2012 that note has been removed. Which one is correct. Is it supported with my model of switch or not.also unable to update boot path in the stack switches, "switch all" is not supported in the current IOS. Master switch has new boot path but unable to change in slaves.
I do have C3750G-12s switch which is not able to boot as of the expected. Every time when I break the stack and try to use console i got a weird output from my console output. we need the stack to be break and use those switch separtally .
I have been experiencing a strange problem i have a switch stack of 3750 in which 4 switches are cascaded. there is one one switch shows PROVISIONED status when I run "show switch". i have verified the stack cable connectivity its OK.
now when i try to console that particular switch i am unable to access it as well. I tried to reboot that switch and on reboot it only shows one LED syst blink once and after that remains constant and nothing happens to other LEDS. from the back of the switch FAN is working fine.
Lets say i have 2 3750 switches stacked via backend stack cables. Now if a packet needs to go from 1 switch in the stack to second switch in the stack, will it travel via stack cable or do we need to connect both switches via uplink ports (ethernet or sfp). I tried reading datasheet but it no wheres mention the actual frame path between switches in stack.

We recently connected a RPS 2300 to our switch WS-C3750G-48PS-E with IOS c3750-ipservicesk9-mz.122-53.SE2.bin.However i do not see any RPS details in the"show env" output.I believe i should get the RPS Name and its Serial and the port number in the output, but i am not finding it in the output. I did reload the switch but still couldnot get this udpated.
I have running a Stack with two C3750G-24TS-S1U with the IOS c3750-ipbasek9-mz.122-50.SE3.Now I want put a new C3750X-24T-S in the existing stack. I have read this is possible. I have running a other mixed stack with a C3750G-12S and an C3750E-48TD. Its running fine until I want to make an IOS update. The update was done with the CW LMS 3.1. After the automatic update and restart only the C3750E had an new IOS the C3750G doesn't have any IOS. Do I have the same problem with the mixed Stack C3750G and C3750X?Do I have to upgrade the IOS by copying the different IOS Versions ( c3750-ipbasek9-mz.122-50.SE3 / c3750e-ipbasek9-mz.122-50.SE3) to every switch ?
I want to upgrade the IOS version of 3750 48PS switches. these stacks are located on different building some of the them having 2 members and some have 3 members in a stack.step by step to upgrade the IOS of these switches.
Currently there are three stacked WS-C3750G-24TS-1U on data centre. I am going to buy a WS-C3560X-48T-L to use 10GbE module. Is it possible stack this switch "WS-C3560X-48T-L" to current switches "WS-C3750G-24TS-1U" ?
can i stack cisco (ws-c3750G-12s) with (ws-c3750X-24p-poe-s) with (ws-c3750-48p-10/100 poe) i mean even a switch is 10/100 and the other switch is 10/100/1000?
I have two Switches which i need to put in a same stack - WS-C3750E-48TD and WS-C3750G-48TS . Possible to do so and also which IOS to put in both the switches as WS-C3750G-48TS is having lower RAM and flash.Whether can i put following IOS in these switches and connect them in a stack as i have read that IOS -- 15.0.1. SE are compatible with both the switches.
a . c3750e-ipbasek9-mz.150-1.SE.bin in switch - WS-C3750E-48TD
b. c3750-ipbasek9-mz.150-1.SE.bin in switch -- WS-C3750G-48TS
I have 8 switch stack consisting of six WS-C3550-48P and two WS-C3750G-16TD running software vesrion 12.2(25) SEB1. When I added new C3750v2-24PS (running image 12.2(50) SE5) in stack so I up-graded the image of existing 8 switches with latest veriosn 12.2(50) SE5. Once I have done with the upgrade then all ports of my stack switches went down after around five minuts. Is it image compatibility issue with existing switches or something else?
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"

We have a cisco stack with 5 ws-c3750-24p 12.2)55)SE3 c3750-ipbasek9-m switches. Can i add a switch to the stack that is the following model: ws-c3750g-48ts 12.2(25)see3 c3750-ipbase-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).
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 a customer with a 3750x4 stack. We rebooted the stack over the weekend and the master did not come back up. Upon investigation it was discovered that tghe master was set for Manual Boot. I tried issuing the "no boot manual" command in Global Config mode but it did not change the variable according to a show boot command. According to Cisco documentation, the "no boot manual" command only works on standalone devices. Any way to change the variable while the switch is a member of a stack?
In my office we bought 7 cisco 3750X - 48PS switches. We configured Data Stacking between those switches. We also want to configure Power Stacking between those 7 devices.
I found in the Data Sheet that we can only configure 4 devices in power stacking at a time. If it is like that how to configure the rest of 3 devices. Need configuring power stacking between those devices in a better way..
power stack cable part no we have is CAB-SPWR-30CM

I need to replace an older 3560 with a new 2960-S and am wondering if the SX SFPs I already have will be compatible with the 2960-S. [code] I cannot find any way to get the part numbers of the SFPs.
i have a Layer3 Switch Cisco WS-c3750G -24T , initially i have a IOS version c3750-Ipbase , recentely i have upgraded my IOS to c3750-Ipservices-M to enable to PBR for my network , i have created all the acl and tried to give the route-map with PBR , the command was initiallying but i am not able to see the applied route-map in my policy route , i have gone through the blog and enabled SDM prefer routing , but no luck .
I have configured DHCP snooping on a WS-3560G-48PS running IOS 12.2(58)SE2 ipservicesk9 variant.When I enable DHCP snooping clients don't get IP addresses, when DHCP snooping is disabled, everything works fine.I have set up a SPAN port and run a capture (attached) on the traffic. Wireshark notes the Seconds elapsed field appeared to be encoded in little-endian but only on some packets. Apart from that, I can see nothing wrong with the DHCP Offer responses from my DHCP server.Attachment config.txt contains the interesting parts of the configuration. Please note g0/32 has been set to ARP inspection trust as without working DHCP snooping it would require a static bind.Is there any way of figuring out which option can't be parsed? Is there a way to force forwarding of unparsable DHCP packets while still running DHCP snooping?
This feature doesn't work as advertised on the Release Notes and other documentation. After 12 hrs of lab work and a tlwo day support call to TAC, they finally came back to me that:
IOS Upgrade works well if you use the command force-reload, without force-reload, it won't work. --"of course with this command the complete stack will go down and the purpose of RSU will not serve"
Then they pointed me to a bug that I could not find in the bug tracker unless I searched by the bug ID number ?? CSCua78897
Unfortunately this bug has a closed status and is not slated to be fixed ?
I can see the boot file at 192.168.100.1 but I can never get into the GUI. The unit boots up, fans running. Eventually the power light flashes red. I don't have the unit hooked up to anything else except a laptop to try and configure it.
Customer is using SUP720 with SP rommon image version 8.1(3), he is trying to boot the new ios image from disk0, but he gets invalid magic error. he fomat the disk0 but still he gets error when he boots from disk0. He suspect that it can't be flash problem but can be software of hardware as he has two flash with same issue on 2 switches.
Customer wanted to recreate, I tried in the lab, i was able to load from disk0, but sup in lab had 8.5(4).
Customer wanted me try with 8.1(3) version. But i was unable to downgrade the SP Rommon image. SP rommon is running in Gold region and I loaded the 8.1(3) from both disk0 and sup-bootdisk, even preferrence was given to region1 but still sup came up with gold region itself.
* Will i be able to downgrade from 8.5(4) to 8.1(3), if so, what are the steps.
* is there any limitation or bug where 8.1(3) will be unable to read disk0.
I have setup a home lab for my CCNASecurity studies and have purchased a 2511 to serve as an access server. The 2511 was advertised as fully operational but when I powered it up this is the first error message I get.....
ERR: Invalid chip id 0x80B5 (reversed = 0x1AD ) detected in System flash
From my research it appears this may have something to do with an old ROM and newer flash, here is the ROM info....

Could this be a simple as a ROM upgrade which I have found on eBay for $10.00? Or do I have a larger problem?The boot continues appearing normal until it gets to ....
%SNMP-5-COLDSTART: SNMP agent on host Terminal is undergoing a cold start and then completely hangs.
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.
I am trying to do ios upgrade on 5 stacked 3750 switches. All the switches have different model number, so i am wondering which image file i should download. As far as i understand all the stacked switches should have the same IOS, i may be wrong. The switches have the following model numbers and SW images;
We have several stacks of 3750 switches where this problem is occurring. All of the switches are running IOS version 12.2(50)SE3. (Yes, I know it's old.)
We're seeing inconsistency in how the stack reports members when issuing the following commands:
sow switch show version show inventory
Not all members are showing up in the output of the "show version" and "show inventory" commands. For example:
HUNTI-WV-WDAC03#sh switch H/W Current Switch# Role Mac Address Priority Version State ---------------------------------------------------------- 1 Member 108c.cff2.ea00 15 0 Ready 2 Member 8cb6.4f0a.a600 1 0 Ready *3 Master 8cb6.4f0a.9c00 1 0 Ready (all three switches in stack are displayed)(code)
I am wanting to etherchannel from a 3750 stack to core Layer 3 switches (also 3750) with a cable going to each core switch, I have put both core switches and the stack under a 28bit subnet mask, but I dont seem to be load balancing across both links.
