I've been asked whether we can use HP-branded 10G SFP+s (P/N 455885-001) in Nexus 2Ks to provide 10G connections to HP C-Class enclosures. We've used HP-branded twinax, and Cisco-branded SFP+s and twinax, but we have a raft of HP 10G SFP+s sat in a store room gathering dust and now we want to save some money by not having to buy the Cisco parts to match.
View 1 RepliesI need to replace an older 3560 with a new 2960-S and am wondering if the SX SFPs I already have will be compatible with the 2960-S. [code] I cannot find any way to get the part numbers of the SFPs.
View 7 Replies View RelatedMy inherited network has a Cisco Catalyst 4506 with a WS-X4124FX–MT fiber card that connects to twelve Cisco 2950 switches over 62.5 micron multimode fiber at 100 Mbps. I do not know my run lengths (or even where the conduits run), but the furthest switches are well over a thousand feet from the server room. Any appropriate test equipment to provide this information soon.
We are looking at upgrading the main switch to a Catalyst WS-C4507+E with two WS-X4712-SFP+E cards and the closets to Cisco 2960S-48TD-L switches. Assuming this is a reasonable move, my question is about choosing the appropriate SFP’s for our current and future needs.
I am aware that 62.5 micron multimode fiber is the least favorable for extended lengths, but I will not be in a position to replace it for at least a year. If I purchase 10 Gbps modules, like the SFP-10G-SR or SFP-10G-LRM, can they “throttle down”, either automatically or by setting a parameter, to communicate at slower speeds over distances that exceed their 10 Gbps maximum link lengths on multimode fiber?
Are the LC SFPs interchangeable with the 3560 V2 POE switchThe P/N number we have on the LC SFPs are 30-1301-04.Will this P/N number suit bothe the 2960-S and 3560 switches
View 1 Replies View RelatedWe have bought four Cisco 3750X-24 Switches with IP Base license for 2 offices (2 switches at each office). The offices are connected with 1 fiber pair and 2 CWDM units. We have 6 CWDM SFP (2x 1470nm, 2x 1490nm and 2x 1510nm). All the switches are up and running with 1 problem: the SFP's in the SFP+ position didn't work.
Only the gigabit port 1/1/1 and 1/1/3 are connected. Gigabit 1/1/2 stay disconnected. I already did some test with other SFP's and labels. Do I need to disable the ten gig ports in the configuration?

To do that I would like to be able to sniff the traffic traversing our 7k. However, as the 7k doesn't support remote span we have to span locally. This means that I have to connect a pc to the Nexus and sent the span output to that port. However, our 7K is only equipped with N7K-M108X2-12L modules, which contains X2 10G ports. I found the CVR-X2-SFP10G X2 to SFP+ convertor module, but I wonder whether this supports a 1G copper SFP. If it doesn't it would be wasteful to buy one. On the page concerning the module I only found 10G fiber sfp's which are supported.
I need to extract the serial numbers of SFPs which are plugged in a SG-200-18.For information, SG-200 doesn't have a CLI ... only a Web GUI.I just find this information : [URL]

I have 2 NEXUS switches in VPC. When I create/delete a VLAN gets updated in the same switch, but the VLAN information does not get propagated to the neighboring switch. Revision number remains the same even if I modify the VLAN. Had also tried changing the VTP status to transparent mode & reverting it to client mode but no luck.Have double confirmed on the VTP domain names & password. However the same setup in different location which works perfectly fine.

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.
Connecting a legacy Nortel switch (425/450/470/BPS) to a Nexus 7000 via gigabit fiber? I have a customer trying to do it and they say that the connection never comes up. The support on the Nortel stuff is long since expired, so Avaya is not being particularly useful. Apparently Cisco says the issue is "fast link pulse to the BayStack to determine the capabilities of the uplink and the BayStack is returning all zeros." I have not verified this and actually have not yet gotten my hands on the Nexus side of things

How to properly power down the Nexus 5000 and the fabric interconnect switches? I have looked up and down cisco's and google web for steps, but they are all coming back with the answer to just disconnect the power cables after you have power down all the windows os and exs servers. Before i do that, I just wanted to make sure that that's the correct way to do it or if there are actual commands that I will need to run on the devices to properly power down. I know that the FI do have a command to reboot, but i need them to completely be power down.
View 3 Replies View RelatedI have a router on which I would like to create a port channel that spans two different Nexus 2248TP switches, and then create a couple subinterfaces on the router's po interface.

The company I work have finally decided to enter the 21st century and invest in a new telephone system (Interactive Intelligence) to replace the legacy system which has served us well for the past 10 years. The project has only just started and involves upgrading sections of CAT3 cabling to CAT6, replacing Cisco 3550 switches in one area of the building with Cisco 4507 switches and upgrading our Core switches with Cisco Nexus 7010's. The area that concerns me most is enabling the network for qos as I have very little experience with it. At the moment Im trying to read as much documentation as I can on QOS to bring myself up to speed.
The access layer switches will consist of a mixture of Cisco 3750 & 4507 switches connected to Cisco Nexus 7010 switches which will form a collapsed aggregation & core layer.
Basically, how I should approach this daunting task of making sure the network will support VOIP.
Trying to connect 2 switches together (both 2960G 8 ports). I have an SFP in each (GLC-LH-SM). They are connecting over SingleMode Fibre using the correct cabling. The fibre cores have been tested and are all ok also.
I can't get no Layer 1 connectivitiy at all. Just dead. I have tried 4 different GBICS, swapped cabled etc.. I have forced the media type to use SFP. No link light....
I thought it would just be a case of plugging in the gbics cables and off I go! I read about forcing the speed and duplex on the port but because the port if SFP, the speed and duplex settings are not available. This seems to be hard coded.
I am in the process of migrating our existing server farm subnets to our new Nexus server farm and I discovered something I wasn’t expecting. My intention is to migrate our existing legacy server farm which is comprised of for paired 3750 switches off of our core 6509s and onto the Nexus and connect them to the 2232s via multi gig port-channel connections, two port channels per switch stack.
NOTE this is expected to be a temporary move as next year we intend to install additional N2Ks and move servers over to these directly. But to minimize the outage/downtime it will be better to move the subnets and switchs all at once.
These connections would be grouped 1 gig connections as port channels, one from each switch into one of the two 2232s.
Problem I discovered is Cisco does not intend to have switches connected to the Nexus and it immediately disables the ports when they see BPDUs.
I found a config that does work and it does fail over from one port-channel connection to the other but with the limitation that when the original port channel comes back online it does not fail back over to the original one, an acceptable situation for us. But I am wondering if Cisco would support this design if we did experience issues down the road.
The only issue I really see is to get it to work the config is different on the two N5Ks, see the pert config below for the connections. Both are running the same OS
