3750 E with SFP-10G-SR

Hi,
I have a WS-C3750E-24TD switch. I want to connect SFP-10G-SR to this switch. But it has X2 slot and documents says that SFP-10G-SR can be pluged in to this device. How it is possible.
Thanks.

To use the SFP+ transceiver, SFP-10G-SR, in your X2 slot, you need to purchase a Cisco OneX converter,
CVR-X2-SFP10G=. This solution allows you to start the migration to the smaller form factor 10G transceiver being used on most of the newer hardware.
Otherwise, you could use the standard X2 transceiver, X2-10GB-SR.
Good luck!

SFP-10G-LRM interoperability with SFP-10G-LR

I previously included this in a more complicated query (“Interoperable ASR1000 XFP for SFP-10G-LRM ?”) that didn’t generate any responses, so here is the revised question:
Will a SFP-10G-LRM interoperate with a SFP-10G-LR if I connect using single mode fiber?
(Fiber length would not exceed 100 meters.)
Power and wavelength specifications for the two SFP+ modules seem to indicate that they would work together:
http://www.cisco.com/en/US/prod/collateral/modules/ps5455/data_sheet_c78-455693.html
I’m just concerned that there could be some protocol differences. Otherwise I’m not sure why there would be two different standards, i.e –LR and –LRM.
I checked the "definitive source for everything" and that didn’t clarify LR/LRM interoperability either:
http://en.wikipedia.org/wiki/10-gigabit_Ethernet
Thanks.

AFAIK they should interoperate over SM fiber distances in the range you noted. Protocol-wise the encoding is definitely interoperable. The concern is generally receiving light at optical power levels the receiver can translate into electrical signals faithfully (and of course transmitting at levels adequate for the distant end to do the same).

Interoperable ASR1000 XFP for SFP-10G-LRM ?

I have a 4507R+E switch with SFP-10G-LRM (in WS-X45-SUP7-E) that I want to connect to an ASR1006 with SPA-1X10GE-L-V2.
What XFP can I use to implement my required 10G uplink?
I'm looking at XFP-10GLR-OC192SR [with signle mode fiber], but I don't know if that is interoperable with SFP-10G-LRM.
I suspect the XFP-10GLR-OC192SR would work with a SFP-10G-LR but I have already invested in the SFP-10G-LRM.
As an aside, will my SFP-10G-LRM interoperate with a SFP-10G-LR if I connect using single mode fiber?

Sfp-10g-lrm dropping link

I have 2 switches WS-c2960s-24PD-L one of the SFP ports on both are connected to other switches running the 10g-LRM SFP modules. The two 2960 in question are connected by 1000BaseSX SFP modules. When i try to replace the !gigs with the 10gigs (on both ends) the config is the same on both ends. when i swap out the sfp the link will come up for a few mins then drop. i can do a shut/ noshut on the interface and it will comeback then go down again. Can any one give me some idias to try This link is working fine with the 1Gig SFP.

What is the distance of the fibre? If the original was running on GLC-SX-MM then you should've replaced them with SFP-10G-SR and not LRM.

SFP-10G-LRM modules with MM fiber OM3

Hi All,
Can the Cisco SFP-10G-LRM transceiver be used with Multimode OM3 fiber? if so, what would be the cable distance?
thanks

The SFP+ data sheet does indicate support for OM3 & OM4 fibers (no launch cable required). 220 meters looks to be the link length spec.

X2-10GB-LRM to SFP-10G-SR= Compatibility

Hi,
Can you help me in this ?
I have two 10Gig modules.
On 6500, i have X2-10GB-LRM and on 3750-x i have SFP-10G-SR= .
you can use it with fiber cable and patch cord to connect the two devices?
thanks

Hello,
SFP-10G-SR is a MMF and it uses a LC duplex connector.
X2-10GB-LRM is also a MMF and it uses LC duplex connector.
so they are compatible.

Cisco 4900M integrated X2 ports, CVR-X2-SFP10G and SFP-10G-SR

Hi,
We are going to order two(2) cisco 4900M switches for core and twelve (12) 2960S switches for access (4 stacks with 3 switches each), connected to the core with 10G MM optical paths (up to 300M each). In addition I have one gigabit half-card but it is not related to my questions here. Please see my attached diagram.
So my questions are:
1. Point 1.Can we use integrated eight X2 ports of every of the both 4900M switches as plugging into four of them four convertors CVR-X2-SFP10G and to plug on every of the convertors sfp tranceivers SFP-10G-SR - as it is described on the diagram, or I need for something more in addition to described? I found only some minimum soft releases to use as requirement to use these convertors and sfp tranceivers, but is there something additional I need?
Note:I'm asking that because Dynamic Conf Tool doesn't give me to do such configuration, actually these convertors and SFPs are missing there at all, but it sometimes happens with some products... In documentation it is described this should work (if I didn't pass something which is my main consern and why I'm asking here).
2.Point 3.If this shouldn't work, the other alternative (not described in my diagram) is to use X2-10GB-SR modules without any SFPs - just ot use SC connectors for the optical cables instead of LC. So my question in that case is will 10G links work between X2-10GB-SR at one side and SFP-10G-SR at the other side where I have 2960S switches and this is the only option? Is is expected to have some problems in that scenario?
Note:Actually if Point 1 is workable I prefer to use it instead of Point 2 because of minor price optimization when using SFPs with convertors in comparisson to X2-10GB-SR.
3. If the both variants are possible, which one is preffered and why, what advantages does it have (for example low latency of something else)?
Thank You in Advance
Asen

Just for your information, a fiber link does not care if one end of the fiber has an GBIC (SC-type connector) and the other end has a SFP (LC-type of connector); or any other transceiver footprint (X2, CFP, etc.).. The thing that is important is that each module is the same specification, and matches the fiber type and link length of the network (10GBASE-SX in this example).
Good luck.

Can the SFP-10G-SR down-support connect to SFP 1000BASE-SX ?

Hi everybody:
today i use the SFP+ "SFP-10G-SR" in Cisco Catalyst 2960S-48TD-L connect to 1000BASE-SX SFP in 6509's module WS-X6724-SFP.
the port setting is trunk,but they don't work, even the led don't flush. then i also use the 1000BASE-SX SFP to replace SFP+ SFP-10G-SR in
2960S-48TD-L, then they cany working.
i look up the cisco data sheet , there are no data sheet to satament the 10G sfp+ can't down support 1G sfp. so i want to confirm the problem.
otherwise, the 10 SFP+ only can use for 10G SFP+ ; can't down suport 1G SFP.
this means: if you want to use the 10G SFP+ the other old device also need to replace.
thanks~for your help!!

Hi Marvin,
I found this conversation today, as I am looking for answer on question similar to question that Jerry asked, while opening this discussion.
So, my problem is the following. At some location, I need two 10GB and one 1GB connection over optical cables. To minimize costs, I tried with WS-C2960X-48FPD-L, but as it contain only two SFP+ ports, I tried with two WS-C2960X-24PD-L that will be connected with stack modules.
So, having two WS-C2960X-24PD-L, I can have 2 x 2 1GB SFP+ ports. There are two opened questions:
1. Can I put 1GB SFP transceiver module in SFP+ port (as I must have one 1GB connection to remote site)?
2. Can I use stack of two mentioned 2960 24-port switches, in a way that I use one of them for two 10GB connections (using SFP+ ports for 10GB connection), and second member of the stack in a way that one (of two available) SFP+ port is used for 1GB SFP connection (using SFP+ port as mentioned in question 1)?
I am not sure if your previous statement covers my questions, as it is not clear if 1GB SFP transceiver can be inserted in SFP+ port on WS-C2960X-24PD-L (or any other switch that has SFP+ port).

QSFP-40G-SR4 to four SFP-10G-SR

Hello,
In 40G QSFP transceivers data sheet, regarding SFP-40G-SR4, Cisco wrote: "It can also be used in a 4x10G mode for interoperability with 10GBASE-SR interfaces up to 100m and 150m on OM3 and OM4 fibers, respectively."
So, can i connect Nexus 5572UP equipped with "six true QSFP ports" to Nexus 7706 using QSFP-40G-SR4 on the side of 5572UP, and 4 x SFP-10G-SR on the side of 7706? Somehow, i think that this is not possible, but i want to be sure...
Thanks,
Wojtek

You can break out the single 40G port into 4 separate 10G ports and use a QSFP to 4 LC breakout cable to connect one or more of the 10G ports to the 7706. You have to enter the following command to enable the 10G breakout of the 40G port though:
interface breakout slot <slot #> port <port range> map 10g-4x
I believe you have to specify the port range as groups of 3 on the 5600 platform and they are on module 2 so the command would look like this:
interface breakout slot 2 port 1-3 map 10g-4x to breakout the first 3 40G ports into 12 10G ports.

SFP-10G-ER on CWDM?

A standard SFP-10G-ER is supposed to run transmit/receive on 1530 to 1565 nm, is it possible to use this over a 1550 nm channel in a CWDM solution like the CWDM-OADM4-2= ?
I trying to find a cheap way to combine a 10G Ethernet and a 4G FiberChannel (with DS-CWDM4Gxxxx) over the same fiber pair.

Yes, based upon a "typical" 25km fiber link, you should be able to use the CWDM & DWDM components you outlined above to create a point-to-point 4G CWDM & 10G DWDM link over two dark fibers. This is prefaced on the dark fiber's total link loss at 1550nm being less than 8dB of loss.

Fiber Patch cord bewteen X2-10GB-SR and SFP-10G-SR

I would like to know which patch cord should I be using between X2-10GB-SR and SFP-10G-SR. The mention of part no would be very helpful.
Thank You

CSCO11584685 wrote:dude, double check before you answer.according to http://www.cisco.com/en/US/docs/interfaces_modules/transceiver_modules/compatibility/matrix/OL_6974.htmlX2-10GB-SR has SC connector, and the SFP-10G-SR has LC connector. so that would require SC-LC connecitor with MMF, 850-nm wavelength.
Thanks Sulaiman for the correction. I should not have relied purely on memory as it has potential of failing :-).

Nexus 5548 with FET-10G problem

hi,
i have single 5548 NX-OS 5.0.2N1(1) version connected to single fex 2232 via 4 X FET-10G. on the 5548 it is the first ports, at the 2232 it is at the last 8 ports.
after configuring appropriate FEX configuration i cannot see any link between them. when i am changing from FET to SFP-10G i get a link.
what could be the problem ?, do i need specific configuration ?
thanks,
Avi.

Hi,
Yes, you need to configure the 5548 ports as " switchport mode fex-fabric " before you connect the FET SFP's in the ports.
The FET is supported on N5k only when connected to the uplink of a FEX, however, the SFP will be non accepted
if the port on the 5k is not configured with:
"switchport mode fex-fabric"
Could you make sure that you have that configuration and that check again?
HTH,Please rate if it does.

SFP-10G-AOC10M does not detected by WS-C2960X-48FPD-L

Hello.
I've got two SFP-10G-AOC10M optical transceiver modules, and want to use them as uplinks for Catalyst 2960-x switch stack to 4500-X.
When I insert SFP modules to Cat2960-X I get next messages in log:
%PHY-4-SFP_NOT_SUPPORTED: The SFP in Gi4/0/50 is not supported
%PM-4-ERR_DISABLE: gbic-invalid error detected on Gi4/0/50, putting Gi4/0/50 in err-disable state

%PM-4-ERR_DISABLE: gbic-invalid error detected on Gi5/0/50, putting Gi5/0/50 in err-disable state
Looks like switches detected this modules as 1G not 10G.
According to Cisco 10-Gigabit Ethernet Transceiver Modules Compatibility Matrix these modules should be supported by Cat 2960-X with 15.0(2)EX IOS release. I had 15.0(2)EX5 release and even upgraded to 15.0(2a)EX5.

Any ideas?

Hello.
That is the problem. Switch has 48 Gigabit ports and they appear as Gi4/0/1-Gi4/0/48. And two uplink ports for SFP or SFP+ modules. 10Gig uplinks module should be detected as Te4/0/1 and Te4/0/2. Gigabit will be detected as Gi4/0/49 and Gi4/0/50.
Once I insert SFP-10G-AOC10M to the switch uplink port I get messages in logs:
%PHY-4-SFP_NOT_SUPPORTED: The SFP in Gi4/0/50 is not supported
%PM-4-ERR_DISABLE: gbic-invalid error detected on Gi4/0/50, putting Gi4/0/50 in err-disable state
So instead to be detected as Te4/0/2 it is detected as Gi4/0/50.
I've tried to insert into uplink ports two other modules: GLC-T (1gig) and SFP-H10GB-CU3M. And they are detected correctly(see two last outputs in first post).
