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?
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?

We've just purchased a WS-C3750-24FS-S, only to find that the 100baseFX ports will not work over Single Mode fibre, backhaul links. Any way or a device that convert from MM to SM?

View 7 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 3 Replies View RelatedIs it possible to upgrade a c3750-stack one member at a time to avoid downtime? I need to keep L3-functionality up.
If I have one etherchannel from access-switch (2 channel-ports in 3750, in different stack-members), my 3750-stack as a distribution layer switch, and another etherchannel (also spread over multiple stack members) to core, can I upgrade the entire stack without traffic interruption?
a) I have three C3750-X switch stack together as my SAN switch and running on the new 15.0 release which is 15.0(1) SE.
b) Recently the master switch rebooted without any explanation. Create ticket with TAC and got an answer that it is due to a bug with ID: CSCtr31957.
My question is, which release that should i choose either the 15.0(1) SE3 or the latest 15.0(2)? Will it affect any of my configuration if i change to 15.0(2)?
Finally, what is the best practice to upgrade IOS in a stack whether to upgrade it 1 switch at a time or do it to all at once?
Does 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.

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.

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).
I have a couple of WS-C3750X-48T-L and a couple of WS-C3750X-12S-S, I want to stack all four of them together into a single stack.

Can the LAN Base switches upgraded to IP Base?
View 3 Replies View RelatedI am having an issue on a Cisco 3750 stack where when the stack master is rebooted, all my lacp port-channels drop and then come back up again. After doing some investigation It seems that it is happening because of lacp using the stack master mac-address as part of the system-id, so when the stack master reboots, the stack mac changes. I see that there is the command: stack-mac persistent timer 0
There is this warning about using this command:
When you configure this feature, a warning message displays the consequences of your configuration. You should use this feature cautiously. Using the old master MAC address elsewhere in the domain could result in lost traffic.
My question are:
Are there any other consequences to using this command (apart from moving the switch/mac to another location in the network)It mentions 'If the entire switch stack reloads, it acquires the MAC address of the master as the stack MAC address' Is this still the case if you have the stack-mac persistent timer to 0? Does using channel-group mode on for the port-channels still use the same mechanism of having a system-id? (Will the channels flap using 'mode on' when rebooting the stack master.
I am not on site and I have not seen a WS-C3750V2-24PS-S. Customer has a stack of 6 x WS-C3750V2-24PS-S and one unit has failed. We do not have a WS-C3750V2-24PS-S spare. Can we replace it with a standard WS-C3750-24PS-S (not V2) switch and be part ofthe stack.
1. Are there any traps gotchas?
2. What about IOS versions - aren't they different for V2 switches
3. Are the stack ports and stack cables same for both WS-C3750V2-24PS-S and WS-C3750-24PS-S
4. What is the main reason for bringing out the V2 switches. What features do they have extra?
Can i put in stack the ws-c3750X-12S-E and ws-c3750X-48P-E? considering the follow features:

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 6 Replies View RelatedI have a 3750-x switch with module C3KX-NM-10G. In slots 1 and 3 I have GLC-T inserted, no problem. When I try to insert GLC-T into slots 2 or 4, I receive the log messages that are listed below. I can swap/mix and match different GLC-T's in slots 1,2,3, and 4, the SFP's are recognized every time in slots 1 and 3, and are never recognized in slots 2 or 4.
Slots 2 and 4 also double as the Ten Gig interfaces, which we are not using right now.Is there some trick to getting the switch to recognize SFPs in slots 2 and 4? [code]
confirm the C3KX-NM-10G module is hot-swappable.i have checked the cisco's website and it says " Although network modules are hot-swappable, we recommend installing a network module before powering the switch"
What steps i need to follow to install the module?
I have C3750X with C3KX-NM-10G, and have-T SFP in slot 3 ( means it is not in SFP+ slot ).I need to set speed&duplex hard to 100/Full, but if I do the link goes down. I have the same settings on the other side, only IOS version is different.I tried other speeds - 10 and 1000, but no one works with Full. When I change duplex to Auto it works fine.The reason why I am doing this on C3KX-NM-10G is because I need to use NetFlow and cannot use the chassis' copper port. At the moment the ports are connected through a copper patch cord, but in full production there will be a radio link in between that requires 100M/Full to be set hard.I am trying to search for any document that would describe this limitation, but cannot find any. Also port capabilities do not indicate duplex could not be set to full:

A product I could have used a number of times is a expanded version of the C3KX-NM-1G device module. To include 2 or maybe 4 more SFP ports. From the layout behind the faceplate there is plenty of space which additional circuit boards could be placed, (which is used in the 2 port 10GB version). I don't need the 12 port fiber switch that Cisco has, because I need a few RJ45 connection at that location, which I would then have to buy additional Fiber to coper Gbics for a few connections where the switch is at. The reason I need something like this is I have a few locations which I get a main feed from the City fiber, then it gets sent out to a number of local buildings on my fiber. Maybe another option is to take the 12port switch, and have an option for 6 rj45 and 6 sfp connections.
