View 11 Replieshave 2 3750's one is an 3750E the other one is a G... Since they are 2 different versions Do I need to correct ios for each for example my 3750E switch i would have
IP BASE
c3750e-ipbasek9-mz.122-53.SE2.bin and for my 3750G switch should i use
IP BASE
c3750-ipbasek9-mz.122-53.SE2.bin
Which would be 2 separate images
There seems to be a lot of conflicting information on what can and can't stack together in the 3750X range.
I know that LAN Base can only stack with other LAN Base switches.
Can IP Base stack with IP services in 3750X? I have also heard that the 15.x.x IOS restricts mixed feature set stacks?
I know that Cisco recommends that all switches in a stack have the same IOS and feature set but having all IP Services in a stack can get too expensive.
I have two WS-C3750-48PS-S switches and I need to add two more. The new part number I am looking at is WS-C3750X-48P-S will these all stack together ?

View 2 Replies View RelatedWe currently have a stack of 3750G switches that are running 12.2(46)SE C3750-ADVIPSERVICESK9-M
Our 3750X is currently running 15.0(2)SE C3750E-UNIVERSALK9-M and I believe we were told you can't stack with a Universal IOS image. We have the universal on there because we have some 10GB fiber connections on it that Cisco told us wouldn't work otherwise.
I realize that the switch versions need to match, but the question is, which version should we work off to have use of the 10GB SFP card?
I need to connect one sw3750E with two 3750X , with Uplinks at 10 GBps. My doubt is the next:
Switch 3750E has two TwinGig Adapter Converting 10 Gigabit Ethernet X2, phisically each twinGig adapter has 2 slots for SFP modules. Can I install sfp+ If I want to use copper for Uplink at 10 Gbps, I just need to install one SFP-H10GB-CU5M transceiver ???? the other SFP slot is disabled automatically?
in the other side 3750X in order to support copper at 10 Gbps a C3KX-NM-10G network module is considered, this will be connected to SW3750E by means of SFP-H10GB-CU5M.
The second 3750X will be connected to second twinGig Adapter of 3750E using another SFP-H10GB-CU5M transceiver.
I'm trying to get some clarity on power stacking 3750X switches. I have a new stack of 6 switches. I know I can only have 4 in a power stack and all 6 in the data stack with a max of 8. I'm trying to find the proper way to connect the power stack cables for the 4 switch power stack.
View 1 Replies View RelatedSuppose I have a 3 member stack of 3750x switches. Members a, b and c.I have all 3 members stacked with all 3 *data* stacking cables in a daisy-chain topology. The 50 cm data stacking cable from switch a (on the very top) to switch c (on the very bottom) just barely reached.Of course, that means the 30 cm *power* stacking cable didn't reach between a & c. Right now, the power stacking cable goes from a to b, and then another cable from b to c. Leaving me with a useless extra 30 cm power stacking cable.
My question is, can switch "a" receive power from switch "c" through switch "b"? Is this just a big electrical "bus"? What if the power supply in switch "b" is removed?Just wondering if there is a need for me to get a longer power stacking cable (one of the 150 cm power stacking cables).
We purchased a number of 3750X 48 and 24 port switches for the College Campus. Am finally getting around to getting them inserted on the network. Working with a WS-3750X-48PF-S and a WS-3750X-24P-L. Have them stacked with the 10Gb uplink on the 48 port switch. Have not been having fun.In the boot sequence, the switches recognize they are stacked, but as soon as they finish boot, I get the message on the 48 port switch: “Stack Port 1 Switch 1 has changed to state down.” Then “Stack Port 2 Switch1 has changed to state down.” Am noticing that I have a message preceding that: “Major version mismatch with stack neighbor.”The 48 port is running c3750e-universalk9-mz.150-1.SE3, HBOOT 12.2(53r)SE2.The 24 port is running c3750e-unversalk9-mz.122-55.SE3, HBOOT 12.2(53r)SE2Most of our 3750X and older switches are running 122-55 or 122.58 code. IP base or Universal. There is speculation that the problem is the 24 Port is Lan base, as the part number might indicate. (WS-C3750X-24-P-L.... I think that is the part number) and the 48 is IP base. Both switches are Universal, and my understanding is that they don't care about LAN or IP Base until you enable a function that falls in the IP Base domain. Then I have to call Cisco Licensing.For these switches, LAN Base is fine, based on the boot message, I feel the real problem is 122-55 versus 150-1 in the stack. So.. the question is: Do I downgrade the 48 port to match what we have in our environment, and what is on the 24 port switch. Or... Upgrade the 24 port switch to match the 48 port switch and have an installation that is not consistent with our environment? I do have two more edge closets to install with this purchase of 3750X 48 port switches.

I tried to calculate concersion time during fail over testing but convergence time was 21 second. I think it is too long...

・I configured Rapid Spanning tree protocol between L3 and L3. (But RSTP's convergence time is 2~3 second..)
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
is it easy to remove the 3750x stacking? i'd like to test one of them on a sunday and keep the other one on production. it's just two stack of 3750x, is it hard and do i really need to remove the cables on the back?
basically i need to put a different config for my testing, i gues i need to remove the cables right? and put it back on the stack before monday.
I am trying to stack a 3750g with a 3750x. At the moment they will not stack with their current IOS as the hardware version is mismatched.
According to various posts this is possible as long as the same IOS is in use. The following IOS are currently in use:
3750g - c3750-ipbaselmk9-tar.122-55.SE5
3750x - c3750e-ipbasek9-mz.150-1.SE3
I have tried to downgrade the IOS on the 'X' to 122-55.SE5 however, i get errors regarding firmware incompatibility.
I am unable to upgrade the IOS on the 'G' to 150-1.SE3, as the size of the IOS image is larger than the available flash (Version 15 IOS for the 3750G (c3750-ipbasek9-mz.150-1.SE3.bin) is 16,074,189 bytes whereas the 3750G has 16MB of flash memory or 15,998,976 bytes total which mean the IOS will not fit).
Has not actually stacked these devices successfully? I understand there may be license implications of upgrading to 15 but at the moment I just want them to stack!
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?

I am not able to find the exact bug for Cisco 3750E stack - Debug Exception (Could be NULL pointer dereference) Exception (0x2000) error. Closest i can find is CSCsa72400 which only affects ver 12.2(20)SE4.All the stacks (3 switches) are running 12.2(50)SE3, It appears that the switch 1 crashed and reloaded. My hunch is its software but i cant find any related bugs. It could be hardware issue as well ?

I have a 3750X 24 port switch (with NM-1G network module) running IOS 15.0(1). Is there any benefit or reason to plug in the included Stack Wise cable and loop it back to itself in a single switch installation?
I don't see any recommendation in the documentation. The data sheet indicates a single switch is a non-blocking device so I'd think there's no bandwidth advantage like there is when connecting an actual multi-switch stack and needing to close the loop for the full 32 Gbps stack bandwidth.
About an hour ago I had the master switch on one of my 3750x (WS-C3750X-48PF-S) stacks crash. The only two items we've found that could have caused this issue are the roughly 1.3 million big buffer misses and several of the following in the syslog
SLT:WARN:No exporter configured for smartlog! I do not have smartlogging turned on, nor is there a netflow exporter configured
sh logging smartlogsmartlog is disabledsmartlog exporter:smartlog pkt length: 64 Total pkts processed: 0Total DHCP Snooping pkts processed: 0Total DAI pkts processed: 0Total IPSG pkts processed: 0Total ACL pkts processed: 0
I did not see any traffic spikes prior to the crash.
This stack has been stable since it's last IOS upgrade from 12.2(58)SE1 to 12.2(58)SE2 back in October 2011 so this has me a little worried.
I've 3750X switch that isn't loading email. then I went to rommon mode and accidently for "format flash". after that I loaded 15.0 SE2 s/w on it using tftp server but it doesn't boot up with that image. flash had only .bin file after I loaded it from tftp server.
since it wasn't booting up, I did format flash again and thought to load image again from tftp server but now, it doesn't load image from tftp server.
I have a 3750X four-switch stack acting as the core of a fairly simple LAN. All I need to achieve (and this seems inordinately hard, but it is entirely likely that I'm just being dense) is to get access to the internet through my core switch, through the firewall and out through my VSAT. I've spoken at some length with the firewall providers (Cyberoam) and they tell me all I need to do when I migrate onto my new system (Cyberoam is currently in place at the entrance to our existing LAN) is change the local IP address of the Firewall, plug in the new switch to the LAN port, and away I go. Tried that, didn't work, so obviously I'm missing something.
