10G SFP module

Hi all,
I have a Cisco 3850 switch stack with a c3850-nm-2-10g network module which came with some 10Gb sfp's (SFP-10G-SR). I have a 1Gb layer 2 WAN link being provisioned and would like to know if I can connect this 1Gb link via the SFP-10G-SR or do I need to buy a 1Gb sfp module ( 1000BaseSX SFP )
Any information would be much appreciated.
James

SFPs are fixed speed so you have to have the same speed SFP at each end of a fiber link.
Note that if you use both the 10 Gbps SFPs for other connections that Gi1/1/1 and Gi1/1/2 are not available for use. See Table 3 here.

No it won't. Both routers won't even push 1 Gbps.

10G SFP Module absent after reload in Nexus 5548UP

Hi there,
i have a problem concerning two new 5548UP.
After a reload, the 2x2 10G SFP Modules SFP-10G-SR are displayed as "sfpabsent" on a random basis.
When i plug it out and afterwards in again, they work fine an the VPC-Peer link across the two switches comes up.
My 1G SFP modules are all working correctly.
I tested firware version 6.0 and 5.2.
Any suggestions?
Thank you very much!

Hi,

What could cause my SFP-10G-LR module faulty?

I have a SFP-10G-LR module that running fine 3750x switch, but one day without any symptom the SFP not running, from the log it was show link down that is all, no power failure also. So what possible that will cause the module failure?

the interface status show down down, not connected. And i can sure it is inserted properly, i have remove and insert for several time but still the same result, even i plugged it to other port, still the same. I even run show inventory after i insert it, it was showing the correct information and detected by the switch, but still not able bring the link up, Once i insert a new SFP into the same port, without changing any config, the link immediate up.

CVR-X2 module won't recognize SFP-10G-LR module in 6506E 8port 10GE blade

I have a core infrastructure network built on the 6506E chassis. I have the CEF720 8 port 10GE with DFC blades (WS-X6708-10GE). I have purchased 4 CVR-X2-SFP10G (V03) modules, and 2 of each of the SR and LR SFPs for them. What is happening is that any of the CVR-X2 modules with the SFP-10G-LR sfp inserted is not recognized (expample next shows an OK SR sfp, followed by an LR sfp):
Port Name Status Vlan Duplex Speed Type
Te1/1/7 SFP-10G-SR Mod notconnect 5 full 10G 10Gbase-SR
But none of the SFP-10G-LR modules are recognized whether in the same port or blade:
Port Name Status Vlan Duplex Speed Type
Te1/2/7 SFP-10G-LR Mod notconnect 1 full 10G unknown
I cannot find any "bug" on my CCO web. A local Cisco Gold partner says that all should work together. Cisco's web site and data sheets all say it's AOK. This is not looking good. Without the LR modules, These same blades have older CVR-X2 modules with both SR, LR and Copper 10GB sfps installed and working.
What could be going on here?

FRULink 10G SM Module - Can a 10G sm module run at 1G

We recently deployed the WS-C3750X-48T-S with a 10G SM Module. The 10G SM Module has a fiber sfp and ismy only fiber ports. Is it possible to run a 10G fiber sfp port at 1G?

some SFP can work at 100Mpbs speed :-)
C'mon, I'm speaking in the context of the the OP asking if SFP+ can/can't operate in 1 Gbps (and not 100 Mbps).
Yes, there are SFP that can operate only at 100 Mbps and nothing more than that.

SG500 5Gb SFP module

Hello,
I was wondering what fibre SFP module I use to stack SG500 switches at 5Gb.
In the datasheet it says SFP-10G-SR can be used for 10Gb stacks with SG500X switches but doesnt say if it can or can't be used on the SG500.
I am using mulitmode fibre and the distance is less than 200m.
Thanks.

Hi David, yes you are right I have neglected the fact it is twinax. It is also correct about fiber. The problem will remain an actual distance.
The copper modules will work perfectly fine for the 5 gig slots up to the available wire length. A 1 gig fiber module such as MGBSX1 would be a suitable 550 meter or less multi mode solution if the distance does exceed the length of the copper or ethernet.
However, what is not clear is a factual distance. Less than 200 meters is ambiguous and there are 3 correct answers. If this is within 30 feet let's say then the 5 gig is by far an exceptional choice. If it will be outside of the 30 feet then another solution such as a multimode fiber using MGBSX1 will do the trick for a 1 gig link for 550 meters. Also running regular Cat6 can also do this trick for less than 100 meter. Or for a different approach, MGBT1 using Cat6 which is an ethernet module.
It is just a matter of having all information since the ONLY distance mentioned is less than 200 meter. Perhaps I could do better and first ask "How far are you truthfully going"? or "Here's 3 options..."

Compatibility with SFP modules

Hi,
I have a query, I need connect a Switch 6500 with a switch HP, the switch HP has a HP X242 10 SFP module and need connect to the switch 6500 with a module CVR-X2-SFP10G. I need to know if this modules are compatible.
Thanks for the help.

According to the 6500 module installation manual, and a Q&A document,
"Q. What is the difference between WS-X6716-10G-3C and WS-X6716-10G-3CXL?
A. Both modules offer 16 ports of 10 Gigabit Ethernet and share the same base board, WS-X6716-10GE. WS-X6716-10G-3C comes with distributed forwarding card 3C (WS-F6700-DFC3C), and WS-X6716-10G-3CXL comes with distributed forwarding card 3CXL (WS-F6700-DFC3CXL)."
"A sticker is placed on the module faceplate identifying it as either a WS-X6816-10G-2T or WS-X6816-10G-2TXL depending on whether a WS-F6K-DFC4-E or WS-F6K-DFC4-EXL daughter card is installed on the module."
"Not all 10-GB transceiver versions may be supported on your module. Refer to your software release notes to determine if a specific 10-GB transceiver is supported on your module."
It seems you will need to determine which daughter card or forwarding card is installed in the base WS-C6716-10GE board; then refer to the software release notes for transceiver compatibility. The longer reach SFP+ copper or active optical interfaces draw more power, thus they may not be supported with the X2 to SFP+ converter.

Port groups in NX7000 F2 48-port 1G/10G Ethernet module in regard to VDC?

Have couple of questions about assigning ports on the F2 1G/10G Ethernet module to VDC. Thanks for any help.
1) The older 32-port 10G Ethernet module has port groups. When assigning ports to VDC, ports in the same port group should be assigned to the same VDC. Is it the same scenario with the newer F2 1G/10G Ethernet module? If so, where can I find information about mapping between ports and port groups?
2) The older 32-port 10G module has ports in dedicated mode or shared mode due to its 80G bandwidth to the switching fabrid. Is each port of the newer F2 10G module at 10G line rate? If that's the case, I can then assigned any ports to be vPC peer link, as oppsed to the older 32 port module where only one port from a port group can be in dedicated mode to be vPC peer link.
Thanks again

1) F2 has the same limitation. The port-group is grouped by the SoC. Meaning 1-4 is port-group 1, 5-8 is port-group 2, etc.
2) F2 is line rate if you have 5x Fab-2 module. Yes you can assign any port as vPC peer-link but you should consider the MAC limitation when designing such solution.

SFP module not showing up as interface choice

I am trying to configure a 3825 router w/IOS 12.4(3d).
When I install a GLC-SX-MM module, I cannot see the module in the sh diag results and therefore not a choice in the list of interfaces.
When I view the logs, the insertion is logged.
Any assistance would be greatly appreciated,
Chris

Hi Chris,
There are two Gigabit Ethernet ports on Cisco 3800 Series systems. Port 1 is a fixed 10/100/1000BASE-T RJ-45. Port 0 can choose between 10/100/1000BASE-T RJ-45 and an SFP module slot. SFP modules are optional.
A new command-line interface (CLI) allows you to choose between the two media types. The "SFP" option will only come up if there is a SFP module plugged into the slot. RJ-45 is the default.
Please see the following configurations to get this port working:
Cisco3825#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Cisco3825(config)#interface gigabitEthernet 0/0
Cisco3825(config-if)#media-type ?
rj45 Use RJ45 connector
sfp Use SFP connector
Cisco3825(config-if)#media-type sfp
After this you should be able to use and see the SFP on the router. Hope this helps. :)

How to install HP X132 10G SFP+ LC SR Transceiver (J9150A) in HBA card

Hello guys,
I want known how to install HP X132 10G SFP+ LC SR Transceiver (J9150A) in HBA card. Kindly revert back as soon as possible.
Note: If you have screen shots or documents. kindly share me.

HP's support site has a doc on installation and removal of the SFP+ tranceivers:
http://h10025.www1.hp.com/ewfrf/wc/document?docname=c03421066&lc=en
Figured I would post it since I found your question before I found the doc.

NX7K VDC: port groups in F2 48-port 1G/10G Ethernet module?

Have couple of questions about assigning ports on the F2 1G/10G Ethernet module to VDC. Thanks for any help.
1) Does the newer F2 1G/10G 48-port Ethernet module have port groups as the older 32-port 10G Ethernet module? If so, where can I find information about mapping between ports and port groups?
2) The older 32-port 10G module has ports in dedicated mode or shared mode due to its 80G bandwidth to the switching fabrid. Is each port of the newer F2 10G module at 10G line rate or still the same as the older 32-port module? I want to make sure the 10G ports for vPC peer link are in line rate.
Thanks again

Hi there
The F2 line card use the SOC (Switch On Chip) architecture where each SOC manages a group of 4 contiguous ports called “Port-Group”
the port groups on the F2 are broken up into groups of four, 1, 2, 3, 4 are part of port-group1, and then so on down the line in groups of 12 groups
"12x4= 48 ports "
For changing the bandwidth and VDC allocation it is highly recommended to use the entire port group using same attribute/VDC
“N7K-F248 Requires allocation in port groups of four to align ASIC resources”
http://www.cisco.com/en/US/docs/switches/datacenter/sw/nx-os/virtual_device_context/configuration/guide/vdc_mgmt.html#wp1170127
the each interface of the F2 is a "10G line rate" which can provide you with up to 480G per line card
however you need to make sure that you have enough Fabric moduls to support the required bandwidth in the backbend/fabric
for example example each FAB2 can provide up to 110G per slot so to run the F2 with its full capacity you need 5x FAB2
hope this helps

NEW THREAD: 10G SFP+ Auto-Negotiating to 1G?

Can a 10G SFP+ SR optic plugged into switch "A" AUTO-NEGOTIATE to 1G to support a 1G SFP SR optic plugged into switch "B" at the other end of the fiber cable?
In short, what I am asking is whether a 10G SFP+ optic (SR/LR - doesn't matter) can be connected with fiber (of course) to a 1G optic and negotiate DOWN?
If not, how do I connect that 1G sfp+ optic to a 10G sfp+ switch port?
NOTE: I know Cisco SFP+ optics only operate at 10G and Cisco SFP optics operate only at 1G. But my question is a general question about SFP/SFP+. From my understanding, SFP+ CANNOT (regardless of vendor) negotiate down to 1G because the SFP+ standard defines a speed range between 4.25 Gbps to 16Gbps. Can someone verify?

Here is one common Optic SFP that does do both 1G and 10G:
Intel E10GSFPSR and
Intel E10GSFPLR
http://www.intel.com/content/dam/doc/product-brief/ethernet-sfp-optics-brief.pdf
http://www.intel.com/support/network/adapter/pro100/sb/CS-030612.htm (expand section 1)
I know for certain that they do support both 1G and 10G as for quite a while I ran these SFPs with Cisco GLC-SX-MMD, and eventually (now) Cisco SFP-10G-SRs. No config changes or modifications were required to support this functionality.
This was in a UCS server with a supported Cisco UCS Intel X520 card.

FAS2554 UTA2 Ports SFP+ Module requirement

Hello, Have anyone know the Netapp FAS2554 UTA2 Ports have any specific requirement for the SFP+ module?(I means if I purchase one other brand SFP+ moudule, it is possible to comptiable with UTA2 ports?) Thanks in advanced!

Hi, From Hardware universe : The onboard UTA2 ports can be configured as FC Target/Initiator or CNA (FCoE target/Ethernet). The UTA2 ports are based on a dual port ASIC and both ports on each ASIC must be set to the same mode (enforced by Data ONTAP). Install X6589-R6 10GbE SFP+ modules or approved copper twinax cables when using in CNA (FCoE target/Ethernet) mode. Install X6596-R6 16Gb FC SFP+ module when using in FC Target/Initiator mode. Thanks
