  • 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.

  • Catalyst 2960 Problem with Cisco SPA512

    Hi there,
    I hope someone can help me.
    I don't have much experience with switches, I'm doing the desktop support in our company.
    We have Catalyst 4510 R+E to 2 Catalyst 2960 switches and seperate VLAN's for IP Phones and for Internet in one part of our office.
    Now I'm running into trouble with some IP Phones that are connected to the 2960 switches. It appears only to happen with Cisco's SPA-512. I've tried FW 7.5.2, 7.5.5 and 7.5.5b. These phones sporadically drop the call / connection, with the red MIC button blinking. Based on my research this means that it looses Internet connection. I have 1 SPA512 with FW 7.5.1 that does not show these symptoms.
    I have other phones SPA942 and Polycom IP335 in the same area behind the same switches and no issues.
    We've tried to disable auto negotiate and set a fixed transmition rate or either 1Gbps and 100Mbps, both without success.
    I also have SPA512 in other areas of the office just connected to our Catalyst 4510 R+E and they work just fine. That's why I don't believe it has anything to do with the 4510, but I can be wrong.
    That's all I have for you guys. Hope someone can help me to fix / troubleshoot this..

  • Copper cable / GigE Copper Interface as Private Interconnect for Oracle RAC

    Hello Gurus
    Can some one confirm if the copper Cables ( Cat5/RJ45) can be used for Gig Ethernet i.e. Private interconnects for deploying Oracle RAC 9.x or 10gR2 on Solaris 9/10 .
    i am planning to use 2 X GigE Interfaces (one port each from X4445 Quad Port Ethernet Adapters) & Planning to connect it using copper cables ( all the documents that i came across is been refering to the fiber cables for Private Interconnects , connecting GigE Interfaces , so i am getting bit confused )
    would appretiate if some one can throw some lights on the same.
    regards,
    Nilesh Naik
    thanks

    Cat5/RJ45 can be used for Gig Ethernet Private interconnects for Oracle RAC. I would recommend trunking the two or more interconnects for redundancy. The X4445 adapters are compatible with the Sun Trunking 1.3 software (http://www.sun.com/products/networking/ethernet/suntrunking/). If you have servers that support the Nemo framework (bge, e1000g, xge, nge, rge, ixgb), you can use the Solaris 10 trunking software, dladmin.
    We have a couple of SUN T2000 servers and are using the onboard GigE ports for the Oracle 10gR2 RAC interconnects. We upgraded the onboard NIC drivers to the e1000g and used the Solaris 10 trunking software. The next update of Solaris will have the e1000g drivers as the default for the SUN T2000 servers.

  • Ask the Expert: C-Series Integration with Cisco Unified Computing System Manager

    Welcome to the Cisco Support Community Ask the Expert conversation. This conversation is an opportunity to learn and ask questions about Cisco C-Series Integration with Cisco Unified Computing System® Manager (Cisco UCS® Manager) with Cisco experts Vishal Mehta and Manuel Velasco.
    Cisco UCS C-Series Rack-Mount Servers are managed by the built-in standalone software, Cisco Integrated Management Controller (Cisco IMC). When a C-Series rack-mount server is integrated with Cisco UCS Manager, the IMC no longer manages the server. Instead you will manage the server using the Cisco UCS Manager GUI or Cisco UCS Manager command-line interface (CLI).
    Cisco UCS Manager 2.2 provides three connectivity modes for Cisco UCS C-Series Rack-Mount Server management. The following are the connectivity modes:
    Dual-wire management (shared LAN On Motherboard [LOM]): Shared LOM ports on the rack server are used exclusively for carrying management traffic.A separate cable connected to one of the ports on the Payment Card Industry Express (PCIe) card carries the data traffic.
    SingleConnect (Sideband): Using Network Controller Sideband Interface (NC-SI), the Cisco UCS Virtual Interface Card 1225 (VIC1225) connects one cable that can carry both data and management traffic.
    Direct Connect Mode: Cisco UCS Manager Version 2.2 introduces an additional rack server management mode using direct connection to the Fabric Interconnect.
    Vishal Mehta is a customer support engineer for Cisco’s Data Center Server Virtualization Technical Assistance Center (TAC) team based in San Jose, California. He has been working in the TAC for the past 3 years with a primary focus on data center technologies such as Cisco Nexus® 5000, Cisco UCS, Cisco Nexus 1000V, and virtualization.

    Hello Sebastian,
    The different modes of connecting C-Series with UCSM come into play depending on the type of infrastructure you already have along with C-Series and NIC model.
    Cisco UCS C-Series Rack-Mount Servers are managed by the built-in standalone software, Cisco Integrated Management Controller (CIMC) .
    Powerful features provided by Cisco UCS Manager can be leveraged to manage C-Series server by integrating  C-Series Rack-Mount Server with UCSM.
    This not only gives you rich-feature set but also one management plane to operate UCS-B Series Chassis and UCS-C Series Rack Server.
    You will manage the server using the Cisco UCS Manager GUI or Cisco UCS Manager CLI.
    Cisco UCS Manager 2.2 provides three connectivity modes for Cisco UCS C-Series Rack-Mount Server management.
    The following are the connectivity modes:
    •  Dual-wire Management (Shared LOM):
    Shared LAN on Motherboard (LOM) ports on the rack server are used exclusively for carrying management traffic. A separate cable connected to one of the ports on the PCIe card carries the data traffic. Using two separate cables for managing data traffic and management traffic is also referred to as dual-wire management.

    This mode is recommended when you have C-Server which does not  have or cannot support VIC 1225 card (such C-200 server)
    •  SingleConnect (Sideband):
    Using Network Controller Sideband Interface (NC-SI), Cisco UCS VIC1225 Virtual Interface Card (VIC) connects one cable that can carry both data traffic and management traffic.
    This feature is referred to as SingleConnect.
    http://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/c-series_integration/ucsm2-2/b_C-Series-Integration_UCSM2-2/b_C-Series-Integration_UCSM2-2_chapter_011.html
    This most recommended Integration model when using FEX and VIC 1225 card
    •  Direct Connect Mode:
    Cisco UCS Manager release version 2.2 introduces an additional rack server management mode using direct connection to the Fabric Interconnect.
    This mode will eliminate the need for FEX module as Servers are directly plugged into the base ports of Fabric Interconnect

  • Issue with cisco ONS 15310. Slot with Ethernet ports, designed for bridging.

    Hi, guys. I’ve got an issue with cisco ONS 15310 sdh optical network. I’ve got a special slot with Ethernet ports, designed for bridging. Assume, we’ve got to multiplexers, named A and B with ports A0 and B0 respectively. The ios console of these slots says, the configuration is as follows:
    no ip address set on these ports
    Ports are administratively up
    Auto mdix
    Bridge groups are the same on these ports.
    Dot1q tunnel.
    I’m trying to monitor a device with an ip-address connected to port B0. It answers ping if I connect the notebook directly to a device. But if I connect the notebook to port A0 and ping the device pluged in port B0 through the optical network, it doesn’t answer. I tried connections with straight and cross cable.
    Guys, who set the network said, it should work as a point to point bridge with no extra configuration. But it doesn’t. I used wireshark sniffer to lookup what’s happening on port A0. All I see is cdp-s from port A0 and self-announcements of the notebook.
    Any suggestions? Thank you in advance.

  • Stolen the copper cable and you haven't finished y...

    So as title suggests, we had a perfectly connecting broadband (still under 1 mb) but still it worked. Then "someone" stole all the copper cable leading to our village, leaving us without phone and internet for 2 weeks! untill you "repaired the problem".
    as a result of your repairs our perfectly working router suddenly stopped working and we had to go back to using the BT supplied HomeHub (1.0) which was an abortion by the way, we have now upgraded our whole system at our expense ofc and are now connected to the internet. But we still have ping of between 300 -600!! most of the programs on your computer dont know how to deal with that sort of dodgy connection and just say "no connection" etc.
    So how have you completed your repairs if the connection is worse than the pretty lowsy connection before?
    Why did you not while repairing the cabling, put in some of the new fibre optic "infinity" that we were supposed to have got a month ago?
    and no i would rather not call one of your foreign call centres where they just tell you to turn it off and turn it on again, we have been loyal customers for around 6 years, but your forcing us towards going else where.
    I look forward to any feedback,
    Bobby

  • Nat in Cisco 4900M device

    Hi there
    Do you know if it´s possible to configure NAT in a Cisco 4900M device?, Is it possible upgrading the IOS version? or we only can do it with a Cisco 6500 device
    Version 15.0(2)SG, RELEASE SOFTWARE (fc4)

    Layer 3 switches, except for the 7200, will NEVER support NAT.  Period.

  • Linksys WRT54G with Cisco Aironet antennas

    Hi Cisco users,
    I've got a small project:
    I need to provide a wireless network from a farmhous to a piggery:
    Distance about 40 metres, no obstructions
    Equipment:     Linksys WRT54G v3.1
    When i place the wrt54g to the most far point of the house (towards the piggery) i get a fairly stable signal of around 11Mbps
    I want to strengthen the signal via an external antenna, preferrably outdoor.
    i'm thinking of this antenna:
    Cisco Aironet 8.5-dBi Patch Antenna (AIR-ANT2485P-R)
    http://www.cisco.com/en/US/docs/wireless/antenna/installation/guide/ant2485.html
    or the same one as above only with 6 dBi.
    http://www.cisco.com/en/US/docs/wireless/antenna/installation/guide/ant2460.html
    Both the linksys and cisco aironet antenna's has RP-TNC connectors.
    My questions:
    1: Can cisco aironet antenna's work with a linksys wrt54G, based on the same connectors.
    2: Is the antenna strong enough? can i cover a distance of 40/50 meters with this antenna, or with the 6dBi version?
    3: it's a directional antenna. the piggery is straigh ahead of the farm house. How much beam width do i have on the end of the signal for coverage?
    4: maybe i need an extension cable. is this the right one?
    Cisco Aironet 5-ft, low-loss, 2.4-GHz RF cable with RP-TNC connectors (AIR-CAB005LL-R)

    The connector has to be the same but also the impedance. Cisco APs are at 50 ohms. Not sure about linksys ...
    Otherwise if you put the antenna outdoor and there is no obstacle, 40/50m should be reached with those antennas. Take the lowest length of cable possible to put the antenna outdoor though as cable brings loss.
    I can't comment about if the 6dbi will be enough as this would require experience with the same hardware which I don't have.
    My 2 cents

  • SFP-H10GB-CU1M SFP+ Copper Cable module speed shows as Unknown

    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.  I'll work on that.  In the meantime, anyone have any ideas as to the proper behavior here?  Shouldn't it show 10G as the link speed?

    Hi Robert,
    I love the GUI, so easy to navigate, when you get the feel for the layout of the switch options. So going to ask you to use the GUI to find the stacking status and  speed between the switches..
    Step 1.  Select help at the top right of the GUI screen, 
    Step 2.  Type in as a search option "stack speed " then clock go
    see my screen capture below,.
    ( The switch has basically an Administration guide built in., a really cool cool feature  ) 
    So you see the following screen capture that shows the option that I selected;
    Followed the instruction outlines in the online help text,  the following screen capture shows me the stacking speed.,
    I have two by SG500-52P, my SG500X are loaned out to a partner to evaluate,   so i can only run 5G over the SFP-H10GB-CU1M  stacking module on this platform.
    Hope this helps you clarify where to find stack module speed.
    regards Dave

  • Time Capsule does not play nicely with Cisco Router

    Three days ago, I had an older Linksys router attached to our ISP's cable modem by ethernet; the network included a wireless time capsule and apple express base station set up by our son last year (who understands this stuff, but lives 2,000 miles distant).  The router died and I purchased a new Linksys router (E2500).  It is occupying the same spot as the old router, but running with no security settings as yet.  My wife's iMac and two Windows XP laptops work just fine on the network, as well as our NetFlix connection on our TV.  My MacPro, however, can not access the main network - it can see it but won't grab an IP address.  It will, however, see and connect to the router's guest account, although with reduced signal strength.  The Time Capsule is now connected to the MacPro by ethernet (if I make it wireless, it will back up fine, but I can't access Internet or send email on the guest account).  The AirPort Express is unplugged and not a factor.
    Yesterday, I spent most of the day on the phone with Cisco (who claimed AirPort Express will not work with their routers, which I know to be, um, less than accurate), and with Apple Support - who did not help (other than to set up a Genius Bar appointment this morning at the local Apple Store).  The Genius Bar turned out to be a disappointment as well - the MacPro with Time Capsule attached worked perfectly on the main network in the store, but at home, even with a test user account with Admin authority, as they suggested), no go.
    If I unpower Time Capsule, I loose Internet.  With Time Capsule plugged in, I can access my router's guest account -
    Aside from returning this router and starting fresh with a different brand router, any suggestions?
    Thanks for any guidance, suggestions, etc.

    My first reaction is to suggest you ring your son.. !!
    And I guess my second one, would be to remove the E2500, and connect the time capsule directly to the cable modem.. they are equivalent devices. The TC is an excellent wireless router and will work better as the primary router in your network. Turn off the cable modem so it can pick up the new device.. plug the TC directly to the cable modem then turn on both.
    Make sure the TC is working as router.. and you should be able to setup the wireless to connect all your computers etc.
    The E2500 can also be used as a WAP if you need more range. But be aware you have to make sure it uses a separate channel to the TC. Plug it in via ethernet to LAN port not WAN.. and turn off dhcp and set the IP to same IP range as the TC but make it outside the dhcp scope. So for example the TC is running 10.0.1.1 and then make the E2500 10.0.1.254
    The express cannot do WDS to the Linksys.. so what you were told is correct. It may be able to connect via ethernet but not as repeater. But you can do that with the TC now that it is the main router.

  • PoE auto switchover with Cisco 1252 Access Point.

    Dear All
    I have a network for Managed Wireless using Cisco. This is a new network for me.
    I am in problem with Cisco Access Point 1252. My AP's are connected to a PoE Switch. And Cisco AP's are also connected Powered with also Power Adapter with UPS backup.
    But problem is if I disconnect power source of AP Power Adapter , AP is not getting up with PoE. PoE is up only when POWER PLUG of AP ADAPTER is physically pulled out from Socket.
    Question is if it is possible to make automatic Failover by PoE when Power source of AP ADAPTER is down ?? I mean no need to PULL OUT  POWER PLUG of AP ADAPTER.
    Waiting for your rely.
    It is very urgent .
    Thanking You
    Subrun.

    Hi Suburn,
    1- yes it is possible to do failover without unlupping the cable of AC adapter. When power on ACS adapter is off, then the faiolver happens.
    2- with regards to POE, if your switch supporting enhanced POE?
    Powering the Aironet 1250 Series Access Point with Cisco Enhanced PoE
    Cisco  Enhanced PoE was designed for customers who want to install new  PoE-enabled technologies that require greater than 15.4W per port to  function at full capability, such as wireless technology based on the  IEEE 802.11n standard. Cisco Enhanced PoE provides the full power  requirements for dual-radio modules and eliminates the need to run an  additional cabling drop or insert a separate power injector. Support for  Enhanced PoE is currently available on a variety of Cisco Catalyst® switching platforms. For more information on Enhanced PoE, visit http://www.cisco.com/en/US/prod/switches/epoe.html.

  • Dual RG6 Coaxial Cables for Cisco Aironet 1310

    Hi All,
    I would like to discuss if someone has experience using RG6 cables with "F" connectors (instead of Cisco cables) for the connection of the Aironet 1310 with its Power Injector. I mean, if the Cisco dual RG6 cables have something particular, compared to standard RG6 cables with "F" connectors.
    Thanks in advance for any comment.
    Regards,
    Igor Sotelo.

    Nothing special, other than it's a reasonably high grade of cabling.
    Any replacement that you use should have the same loss per foot/meter (or better), and be capable of carrying the power (some inner dielectric may not be as thermally stable).
    If you intend to go a longer distance, keep in mind that the power will dissipate at some distance to the point where the AP may come up, but get flaky under load due to the inability of the cable to pass enough power for the higher processing load.
    Good Luck
    Scott
