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,
We had the same problem with a Nexus 5596 in 5.1(3)N2(1a) last night:
%NOHMS-2-NOHMS_ENV_ERR_FAN_SPEED: System minor alarm in fan tray 1: fan speed is out of range on fan 2. 5812 to 12500 rpm expected. 4072 rpm read
%NOHMS-2-NOHMS_ENV_ERR_FAN_DOWN: System minor alarm on fans: One fan missing or failed
%NOHMS-2-NOHMS_ENV_ERR_FAN_RECOVERED: Recovered: System minor alarm in fan tray 1
%NOHMS-2-NOHMS_ENV_ERR_ALL_FAN_UP: Recovered: System minor alarm on fans: One fan missing or failed
%PFMA-0-SYS_SHUTDOWN_FAN_DIR_MISMATCH: System shutdown in 60 seconds due to fan dir mismatch
%NOHMS-2-NOHMS_ENV_ERR_FAN_DIR: System major alarm: fan direction mismatch with other fan(s)
%PFMA-0-SYS_SHUTDOWN_FAN_DIR_MISMATCH: System shutdown in 55 seconds due to fan dir mismatch
%PFMA-0-SYS_SHUTDOWN_FAN_DIR_MISMATCH: System shutdown in 50 seconds due to fan dir mismatch
After reseating the FANs the switch came up. We'll open a TAC case.

Thanks
Veeramani.GI would like to know in cisco 3900,2900 etc which router are supports 10g sfp modules.
No it won't. Both routers won't even push 1 Gbps. -
Hi there!
I do know if it is some kind of bug, but all the time after reload the CX module all things stop work, regardless of what form do I reset the module.
I already tried to acccess the module and reload, tried to stop services with "services stop" command and after that "reload", tried to shutdown using ASA commands and reload it from ASA... everytime I reload when the module come back all services start perfectly, like example below:

I even can access the GUI using my browser, but all athentication with CDA or AD that before boot was working correctly show up the error:
"Connection failed with error: Could not connect to virtual directory interface."
Everytime I reload I must reinstall the entire module and reconfigure everything. Anyone know if this is a bug that crashes the database or something like this?

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.
JamesSFPs 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. -
Looking for Cisco 6500 E series 1/10 G SFP Module
I am looking for 24 ports 1/10G SFP module for my 6509E chassis and WS-SUP720-3B sup module.
I have found the following from my research
WS-X6704-10GE - 4 port 10G module which supports only 10G not 1G
WS-X6708-10G-3C - 8 Port 10G module which supports only 10G not 1G
WS-X6724-SFP - 24 Port 1G SFP module which supports only 1G not 10G
Thanks for your helpHi datamodule, i see that you are looking for a 24 ports 1/10G SFP module for the Catalyst 6509E. From what i am looking at it's either 1G or 10G. Please check this link for further assistance: http://cs.co/9000YTBE. Feel free to message me for further assistance.

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?Hi Mark,
According to this link:-
http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3750e_3560e/hardware/install/notes/1757202.html

Cisco Nexus 5548UP support SFP-10G-LRM ?
Hi all, I have a question about Cisco Nexus 5548UP. Is Cisco Nexus 5548UP support SFP-10G-LRM ? Because in CCW, i can't configure the SFP-10G-LRM. There is only SFP-10G-LR, SR, and the others, but there's no LRM. Pelase help me to answer this question. Thanks a lot
The LRM is s special case transceiver which supports 10 Gbps over older FDDI grade multimode fiber when used with a mode conditioning patch cord. It is not supported on the Nexus 5548UP.
The SFP-10G-LR is used with single mode fiber for spans up to 10 km in length. It is supported on the 5548UP (and most every platform of Cisco's that takes SFPs).
Please see the product data sheet here. -
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,
ChrisHi 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. :)

CCP Discovery - NM-CUE-EC module has been reloaded
Good afternoon everyone,
I am trying to use Cisco Configuration Professional with a 2800. The following message is logged in Discovery Details whenever discovering the device:
NM-CUE-EC module has been reloaded. Please discover the device after the reload is complete.
Is there something I need to do to complete the reload, since this message is not going away on it's own?
Any and all assistance greatly appreciated.
Thank you!

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. -
Optical Fiber connection between GBIC module and SFP module
Hi
I am in need of help.
I have a 3750 24TS-S, 2 port SFP, switch at the edge. And i have a 4507R switch at the Distribution layer. In 4507 switch I have WS-X4515 Sup IV supervisor engine with 2 GBIC Port and also have WS-4306-GB 6 port GBIC module. I am using WS-G5486 Single mode connector, LX/LH tranceiver to connect to this port.
This is the scenario.. i want to know is it posible to conect one end of the fiber cable to connect to a SFP Module ( 3750-24TS-S, 2 Port SFP) and other end ( WS-X4515 Sup IV supervisor engine with 2 GBIC Port or WS-4306-GB 6 port GBIC module) at the WS-G5486 Single mode LX/LH connector ?????
Plz let me now asap.. i need to give a solution imdtly.
Thanks & regards
JacobDiscussion is never a problem ....;-}
The issue is that the signal is "too loud" and is distorted (or, more correctly, is so loud it overloads the receiver).
The operational envelope for nearly every receiver of any kind includes a bottom number (too weak to hear) and a top number (too loud to understand).
As an example, think about an system where you have a hearing aid that would let you hear someone speaking in a normal voice from 100 feet away ... then having someone scream the same words into the hearing aid from 6 inches away ... the sound would be distorted and you would have difficulty understanding them ... after a while, you'd begein to go deaf and eventually, it would sound normal (until you became completely deaf).
So, what you need to do is look at the transmitter power, and the envelope/range of acceptable power the receiver can hear.
Normally that difference is the optical budget ... given the loss numbers of the media between the two, you can determine if you have enough power to make the trip.
In a Lab environment, you still have to hit the receiver's budget number, but from the other end (the "too high" side).
If you know the transmitter puts out X, and the receiver can accept from Y to (X-50), then you need to add enough attenuation to get X down to (X-50)or lower (but still more than Y).
When you have a transmitter powerful enough to drive tens of kilometers, putting one two meters away from the receiver will pretty much guarantee a burnout (unless you install optical attenuation).
Good Luck

I have set up Cisco switches previously via the hyperterminal and been able to get them configured and operating, but I have limited knowledge of the tools and processes.
I have a 2960-S with 48 ports and 4 SFP modules.
I have good feedback on the 48 ports, but I can not get the SFP modules to ether be recognized or show any activity on the 2960-S. The unmanaged switch I have the fiber connected too, is indicating a network connection and activity, but the 2960-S is not indicating any connection on the SFP modules.
I have added the switch configuration file.Ok. I see you posted your config above, and after reading a bit more here, you're dealing with layers 1-2 of the OSI model at the moment, so let's focus on that. For your unmanaged switch, are you using the same type of SFP? Sometimes you need to use the same on both sides for a link to come up. I have tried off branded + Cisco before and it had lots of problems. Also
If that is not the problem, I would say look over your running-configuration for port 49. It does not appear to have any configuration added to it so far. If every device on your unmanaged switch will be on the same vlan, you can turn port 49 into 'switchport mode access' and 'switchport access vlan 1' as well as 'spanning-tree portfast'.
If not all devices will be on vlan 1 on your unmanaged device, you can try 'switchport mode trunk'. This will allow vlans 1-4094 across by default (you can limit this too). Make sure that the unmanaged switch is set to trunk mode as well, and allowing the vlans you want across.
For troubleshooting, you can try 'show spanning-tree vlan <xxx>' where xxx is the vlan you are having trouble with. Lastly, you can also try to issue a 'show interface gig 1/0/49 counters detail', which will show you all the types of packets entering the port. This varies from ios version to ios version, but it will show unicast, multicast, broadcast, packets below the MTU or above (runts and giants).
I hope that helps : ) -
Hi all,
I bought two Cisco 3560X-24T switches, both wit network module and SFP module for fiber connection.
During the power on process all the light of the network module are on, so this should means that the module is operating.
I've no alarm on led and no alarm on web console.
I can see the SFP module on console (web and telnet) and I can enable or disable it correctly, and from log I can see that the module is detected properly (100Mb) and the port is auto configuring.
Now the problem, after connecting the fiber patch both switch show that the link is down. So I tried to change the patch but same results. So after I looked at SFP (I've 4 for each switch) and none of the 8 SFP is emitting light.
Do you've any suggestion?
Many thanks in advance to all that will answer.
Kind regardsCan you post the output from 'show inventory'?
