Symptoms: The switch hangs - after a hard reboot and after two hours switch No. 2 flew out from the stack. After the reboot, everything returned to normal and now when a few days passed switch works without problems. Devices: WS-C3750X-24T-S
View 3 RepliesRecently one of our stack switch got failed, Rma raised but we received some different part number.The dobut is like can we stack the below switches.

Is it possible to have a WS-C3750G-12S-S and a WS-C3750X-24T-L in the same stack, if so do they need to both be running the same software version/IOS.

View 5 Replies View RelatedI 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 ?

View 3 Replies View RelatedAny issues are reported while configuring power stack ? We did several times with 12.2.58SE1 and SE2, sometimes the power stack is created automatically, sometimes needs to be configured manually. Looks like the behavior is not the same. Maybe it depends on the number/type of switches and number/type of power supplies.

View 1 Replies View RelatedDoes the color strips on C3750X stack power cables mean anything, I mean the green and yellow ones. On all Cisco pictures the green one seems to be plugged in the upper ports. I asked local Cisco representative, but he seems not to be sure. We tried to try different scenarios, and it looks like it does not matter what cable end we use. We do not have any external power supply, only interconnecting C3750Xs.
View 1 Replies View RelatedI am having an issue with adding a c3750x switch to an existing switch stack Currently there is 2 x WS-C3750X-48P and I am trying to add another WS-C3750X-48P to this switch I have cabled the switch to the stack using the stack cables and added the command to provision the switch on the exisitng stack. However when I turn the switch on it just goes on its own stack.
I noticed the new switch had a later version of IOS so have downgraded this to the same version as the other switches but still no joy Here is the sh ver from the exisitng stack

We have WS-C3750-24FS switches stacked supporting users on our LAN. I want take advantage of the netflow capabilities of the WS-C3750X using the C3KX-SM-10G card.
Would I be to see netflow data coming from the WS-C3750's if I stacked it with the WS-C3750X?
Also I read that the C3KX-SM-10G card would support a 1G SFP is that correct?
I have two WS-C3750X-48T-S which is "IP BASE" licensed, which are connected as stack.I need to use Policy Based Routing (PBR) to direct Vlans to two different gateways, and command "ip policy route-map" which is supported only in C3750-IPSERVICES license.Do I need upgrade only master switch with Cisco IOS IP Services - product upgrade licenseMfg. Part#: L-C3750X-48-S-E, or both switches need to be upgraded?
View 20 Replies View RelatedCisco let us try a CISCO C3750X- 24T-S Stack (2 switches) ->> IpBase Sofware licence We've 2 Hyper-v 2008 R2 and one SAN Netapp FAS2040 connected via Iscsi.All was working well with this stacks.Hyper-V see Nas Iscsi interface without problem. Even with basic stack config (no Vlan, ect...).Then, after this test period, we bought a C3750X-24T-L stack (2 switches) to replace the stack lent by Cisco.This one is LanBase Software.
With this stack, hyper-v work very bad ! We've got a lot of Iscsi error in the eventvwr.I can't access luns.So, is there a difference between LanBase and IpBase for a iscsi use ?I put the 24T-S config on the 24T-L switch without pb. So config is the same on both stacks...Also i've got a "TestPortAsicLoopback" = "Failed" on the new stack...I've tried with other stack cables. Not better.
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:

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).
my switch crashed two times. below details about it.

We have a new backbone in our LAN with two C3750X-24S 15.0(1)SE3. Since we change the model of our equipment we can't update NTP on this two switches.We try to update NTP with two firewall Juniper SSG-140 in version 6.3.0r12.0. The two switchs never arive to associate with firewall (we try with the comme ntp server and ntp peer)
So we configure ntp server on our distribution servers switchs (one 4900 12.2(54)SG and one stack of 3750G and 3750E 12.2(50)SE5). They have no problem to update NTP on the firewal.So we change our configuration ntp server on the backbone and we try to update it with the distributions servers switchs. With the command ntp server it doesn't work. With the commande ntp peer it works but not everytime. The core switchs are in "synchronized" state then "unsynchronized" then "synchronized" etc...When they are in "unsynchronized" state there is "x falseticker" raison behind the IP of the ntp peer.
Is it an IOS version problem on our core switch?
I need to recover the passwords for my 3750 stack (2 switches), I have the password recovery documentation but it seems to be referring to recovery for one switch. How do I go about recovery when in a stack, should I remove the links on the switches and recover each one separately?Alternatively can I do a factory reset on them
View 1 Replies View RelatedI 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.
I looking to buy SGE 2010 swith, but I have some question:
1. Can I use 4 SFP ports and stack of two switches at the same time.
2. Is it possible to use for stacking ports other than 24, 48?
3. What is maximum possible number of ports to use for stacking (can I get more than 1Gb thruput).
I would like to find out if the Cisco SFE2000p supports Link-Aggregation in a stack. For instance Unit 1 interface 1 and Unit 2 interface 1 in the same LAG?

I have 3 SLM248G4S switches in a stack (SW1, SW2, and SW3), and want to pull one out and configure it as a stand alone.
If I just disconnect the stacking ports from SW3 and reconnect the bottom stack port from SW2 to the top one of SW1, the two switches continue to function together fine, but SW3 still seems to think it's part of the stack (still shows #3 on the LED screen) and doesn't work at all. I cannot even telnet into SW3.
I have to setup my first flex stack and wanted to make sure I do it right. I have the physical aspect of the stack down. From what I gathered I have to setup the master switch as the highest priority and then provision the other two switches. But I have configs on the other two switches, do I have to delete them? And do I have to setup individual ips for the two slave switches, because from what I saw the master switch is the only one with an ip address? The master switch is a poe 2960S-48LPS and the two other switches are 2960G-48TD
