Cisco Switches :: SFP-H10GB-CU1M SFP+ Copper Cable Module Speed Shows As Unknown
Jul 17, 2012
I have connected 2 SG500x switches using an SFP-H10GB-CU1M SFP+ Copper Cable module. Since the port shows as a 10G port, I would expect the speed to show as 10G as well. However, it shows as "Unknown". This doesn't leave me with confidence that it is being recognized properly. The link is working properly, but I haven't run tests to verify if I'm getting full 10G throughput or not. Shouldn't it show 10G as the link speed?

We currently have the XG1 through XG4 ports on our SG500X switch setup in a LAG with the Cisco 10G-FiberOptics. Everything is working fine,however in the web UI under Port Management->Port Settings the "Port Speed" is listed as Unknown. All other ports report the speed correctly. We have 2 SG500X switches configured this way and both are reporting the same Uknown speed.
Firmware Version (Active Image): 1.2.7.76 Firmware Version (Non-active): 1.2.0.97

Device: Cisco 3550T Catalyst ...Tested working all ports Configured Speed/Duplex both manually and set to auto with same result Problem: No connection when connected to specific Motherboard/Lan chipset that is using Realtek PCIe GBE Family controller (NIC)
Motherboard1:When connected to the 3550T the LED is amber for maybe a minute then goes off
Motherboard2:When connected to the 3550T the LED is Green but Motherboard Nic is amber.In windows under adapter settings, Local Area Connection Both Show red X
Motherboard1:
Os: Win7 Sp1 x64 w/latest updates
Mb: Gigabyte GA-P55A-UD3 v2.0
LAN: Realtek RTL8111E
Motherboard2:
Os: Win7 Sp1 x64 w/latest updates
Mb: Gigabyte x38-DQ6 v1.0
LAN: Realtek RTL8111B
The ports are only configured with
Switchport access
No other filters or access list? I have tried on multiple Cisco Switches 2950T, 3500 and 3550T with same result. what odd is these pc's can plug into a Netgear or ActionTec(Verizon) type of switch and work fine. Is there some command I need to apply to those ports to make it work with these GBE controllers. Or How do I get these Gigabyte Mobo(NiC) to work on Cisco Switches?

We have a site with a number of SG500X switches who are about to have a new server installed.
The server is a Dell ESXi host with a dual port 10Gb NIC supporting SFP+.
I know the primary purpose of the 10Gb ports on the SG500X is for stacking etc. but the switch does come with four 10Gb ports.
Why I wouldn't be able to utilize a 10Gb port as a copper connection to the 10Gb NIC on the server? Anyone out there with a SG500X connected directly to a server at 10Gb?

I am using 10Gig link to connect distribution and access switches. Since we are terminating the cables at multiple locations, we are also doing the link budgeting. The CISCO SFP 10G-LR module data sheet shows two values for the transmit power one of which is maximum power .5dBm and another is minimum power -8.2 dBm. Which value should I choose for the link budgeting.

My HP Envy 14 has an Intel 6200AGN wireless card. Is it not good enough to achieve 300mbps on my D-Link DIR-655? The firmware is current on the router and the signal is 100% almost every where in my home. Even when I'm a few feet away from the router, the most I'm able to get is 130.Do I need to change a setting on the router or upgrade the wireless card?

I have a Cisco Linksys WAG120N running with the firmware version 1.00.12, and it's working a quite fine.During some tests with the nmap command under Linux, I noticed that beyond the ports 80 and 433, another opened port 32764 shows up running an unknown service.This unknown service keeps running after scanning for ports between 1-65535 using nmap in stealth mode. But after querying the modem for operating system fingerprint using nmap but not in stealth mode, this port closes and the service disappears.
By using a browser to access 192.168.1.1:32764, a 12 byte "<random_prefix>.exe" file is download, and its's recognized as a text file. The file contains a "MMcSÿÿÿÿ" string, and the bytes in hexadecimal are "4d 4d 63 53 ff ff ff ff 00 00 00 00".And also, something strange happens after this unknown service goes down: Accessing the modem setup via browser, the settings displayed are different than I commonly use. the encapsulation is set to "Bridged Mode Only" instead the "RFC 2516 PPPoE", and into the Status Tab the Current Time field says "Time Zone string Error". Still in the Status Tab, in the Internet Connection information the "Login Type" is a misspelled "UNKNOW", the interface says "Connected" to a well accessible Default Gateway., the same displayed into the Routing Table Entry. Th Applications & Gaming Tab is unaccessible.After power switching the modem off and on again, everything comes back to normal again.

We use Orion for monitoring. We recently started monitoring a workstation switch and find many occurances of port speed changes indicated. Our workstation ports are configured with auto speed and duplex. Is it normal that we are detecting speed changes on the ports? Do workstations running XP automatically adjust their speed for traffic management or power save? Perhaps something like speeds changing when PC goes to sleep mode but has wake on LAN enabled? Is it possible that the MIB is misreporting?
I realize that there are many different NIC vendors/drivers that might act differently. Just wondering (in others experience) if it is somewhat normal or if there is anything on network I should be looking into as to why speeds are changing? We plan to not monitor workstation ports (only uplinks) on the switch.. but before we do, I thought I would see if what we are detecting needs to be addressed?
Here is an example from Orion of a speed changing. Seems always off hours:
6/1/2012 6:17:52 AM eventWoRKSTATION-3750-CLUSTER - GigabitEthernet1/0/14 · 2nd Floor Patch#11 Interface Speed changed from 10000000 to 1000000000 bps

I have a Lynksys WRT600N. I had DD-WRT on it and it was working great for about a year. One day I changed some minor settings like wireless signal type, reboot it and it's gone. I can not access it from my computer. The network adapter shows "cable unplugged". The lights on the front come on, but I can't get anywhere with it.
I've done all the resets I know how to do, including the 30/30/30 and leaving it unplugged for a few months.

We have a 2960S using a single SFP-10GBase-SR to our Core switch. We are planning connecting the 2960S to a pair of Nexus 5k switches using Copper SFPs. We are already doing this on another 2960S so I didn't expect any surprises.
When I removed the unused SFP-10GBase-SR from te1/0/2, the interface was removed from the config and a gi1/0/50 was created in its place. Once I inserted the SFP-H10GB-CU3M, I expected that it would create a new te1/0/2 interface, but it didn't. I got the following errors: %GBIC_SECURITY_CRYPT-4-VN_DATA_CRC_ERROR: GBIC in port Gi1/0/50 has bad crc %PM-4-ERR_DISABLE: gbic-invalid error detected on Gi1/0/50, putting Gi1/0/50 in err-disable state
I didn't personally order the cables, but there is no Cisco label on them, so I'm assuming it is a 3rd party SFP. After looking at other posts related to unsupported SFPs, I ran the following commands: no errdisable detect cause gbic-invalid service unsupported-transceiver
After reconnecting the SFP, it didn't go into err-disable, but I still received the following error: %GBIC_SECURITY_CRYPT-4-VN_DATA_CRC_ERROR: GBIC in port Gi1/0/50 has bad crc
My other working 2960S appears to be using 3rd party SFP as well, but I can't see the brand. Is there anything else worth trying or should I just suck it up and order Cisco SFPs?

I've got an apple Airport Express and have managed to set it into my network. Airplay works on both Itunes and my phone. However after 10-15minutes the Airplay drops out and the network map shows that the airport express is 'offline'. however the airport express LED remains showing it still have connection to the network. The only way to get it back is to reset the AE. The apple forum has lots of people stating the same problem with WAG120n routers.
-Router Firmware V 1.00.16
-Airport Express firmware version 7.6.1

Recently I have faced following problem in my office, We have purchased two new Dell Server Power Edge R910 with built-in 10GB FC Network card. Service tag of this two servers are given bellow.
1. 7D94C2S
2. 6D94C2S
You can can Check specification of this two server from dell website{ URL}
We have two CISCO switch and model is given bellow:
Brand: CISCO
Model: WS-C3560E-12SD
We want to connect server to switch through FC cable and both switch have SPF module. But when we connect server to switch, link do not establish even switch and server port light become off.
Then we have tested the following things:
1. Connect server to server through FC cable, it is okay.
2. Connect switch to switch through same FC cable, it is okay.
I don't understand why it is not working.

I have 6 of these WS-CBS3012-IBM modules that need to be configured but I cannot access the USB console port. I was told I could just get any DB9- to- USB cable and that would work. I did buy a DB9-to-USB cable and it did not work. I looked up the installation guide for this module and it just said the console cable is DB9-to-USB but with no part number.

This is an odd one, possibly a broken unit but I have a SRW2024P which has been running for a couple of years all OK but some time ago I noticed I couldn't access the web interface. I decided to leave it until I actually needed to change something, which is now!
After much messing around modifying a null-modem cable to work (i.e. connected pins 2,3 and 5) I managed to connect to the console through HyperTerm. Did a full factory re-set and XMoDem'd the 1.2.9 software on again but still no luck.
I tried accessing the web console and telnet with the default IP and tried setting my own IP but can't even ping them.
There are a few other peculiarities: The units MAC address in the console is shown as 00-00-00-00-00-00The units hardware version is blank in the consoleBoth PING and TRACERT tests fail to any address except the units ownTFTP uploads fail to connect (the TFTP server doesn't even log an access attempt)All other clients connected to the switch are working fine and the port statuses in the console show working connections Basically; it is as if the web/config/admin 'module' is disconnected from the actual switch in some way?

We are looking forward to implement IBM BladeCentre Swiches connectivity with Nexus 2k module.I would like to brief you about my network over as follows:
Coreswitch : 6513 ( Layer 3 switch + Spanning Tree root)
Nexus 5010 : Layer 2 switch
Nexus 2k 10G ports based module.
Currentl Solution : we want to connect the IBM Blade Switches (4) as demonstrated in the attached diagram which will be connected to Nexus 2k module as Ether-channel Access port.
Initially we been proposed by our vendor with this design and Now vendor is recommending us to connect the Blade switch etiher to Nexus 5k switch or directly to 6513 core-switches instead of Nexus 2k modules as they say Nexus 2k modules are only to connect the Edge devices .
We do not have ports available on Nexus 5010 to connect the cables from IBM Blade Centre Switches. Otherthan that, incase if we go ahead and connect the IBM Blade switches as access ether-channel access port with Nexus 2k module what are consequences we have to face realted Spanning tree or any other.

We have a Cisco 7206 VXR Router with NPE-G2. As everybody aware that, It has got 3 x Gigabit Ethernet Ports on this. We would like to add Two more Copper Gigabit Ethernet Interfaces. The Configurator does not show any options to add that.Now we have a doubt that, Does this 7206 VXR support how many Copper Gigabit Ethernet Interface ?. There is no clear answer available in the Data Sheets.

We need to deploy a 3750X switch with 10 Gb module. The pb is what SFP to choose ? The 10 Gb ports will be attached to an ethernet 10 Gb RJ-45 Server port. The 10 Gb connection has to be copper (not fiber). Is this reference ok : SFP-H10GB-CU3M= (version 2) ? I mean is it a copper cable with an attached SFP.
