SFP (Cisco GLC-SX-MM) unknown in cisco switch 2960s

I have cisco switch WS-C2960S-24TS-S with IOS 12.2(55)SE8  C2960S-UNIVERSALK9-M when I connect the SFP Cisco GLC-SX-MM to the interface the switch does not know it .

  • Compatibility Cisco GLC-BX and MediaConverter AlliedTelesis

    Goodmorning to everyone.
    We need you help about the GLC-BX SFP compatibility with the Media Converter
    Allied Telesis AT-MC1008/SP.
    In particular we want to try the Cisco GLC-BX with AT-MC1008/SP (1Gbps ethernet trasmission on one single fibre).
    Are there anyone formerly use this solution?
    Can we consider AT-MC1008/SP and GLC-BX compatible?
    Or there are problems?
    Thank you very much.

    If they are both media type LX they should work. You can replaced the AT-SPLX10 Allied Telesysn SFP on the MC with the cisco SFP.

    Thanks for helping me again. I really appreciate.
    I don't hve any NAT-exemptions in Cisco IOS Router. Transform-set I will change soon, but I've tried with tunnel mode and it didn't work.
    Maybe NAT-exemptions is the issue. Can you advice me which exemptions should be in Cisco IOS Router?
    Because on Cisco ASA I guess I have everything.

  • Cisco Network Assistant, unable to add a switch

    I have a network running some 20 switches, two controllers and many AP's.  All the devices that should be able to connect to cisco network assistant can successfully.  However there is one switch that will show in neighbours but will give the message of “unable to connect to device” when I try and add it to the topology. 
    As far as I can see the config is identically to all other similar switches in the network.  I can telnet from a switch (management VLAN) to the switch in question.  However when I try to ping or telnet from the PC running network assistant (different subnet) I am unsuccessful.  However I can ping/telnet to all other cisco device from this PC. 
    The switch is a WS-C3560-48TS and I have included the config for firstly the switch in question and another switch of the same model and config that works correctly.  Any help would be greatly appreciated, thank you.

    The switch configurations look pretty straightforward and mostly correct.
    I notice that the problem switch has "ip routing" global command. Why is that necessary? You are only using it as a L2 switch, yes?  If you use "ip routing" and have no routing process (ospf, eigrp, etc.) running you would need to add a static default route (ip route 0.0.0.0 etc.) and not use the "ip default-gateway" command. Otherwise the switch itself (the SVI) does not know how to leave the management VLAN routing-wise since it is the only L3 interface defined.
    (I might also add "ip http authentication local" on each and I'd definitely disable telnet in favor of ssh)

    show cfs lock gives no output.
    Just to further clarify, we have 4 5548UP switches in the same management vlan. 2 switches are in one location lets say location A and they are CFS peers and are working fine.
    These two switches which are having problem are in location B. All the switches are in the same vlan. Essentially the all CFS multicast messages will be seen by all 5548 switches as they are in the same vlan. I am assuming that this might not create any problems as we specify the peers in the respective configurations. Or do we have to change the CFSoIPv4 multicast addresses in location B or may be configure a different region.

  • Cisco Call Manager 5.1 and Cisco VoIP Gateways

    Hi,
    I have Cisco Call Manager 5.1 with Cisco 2800 series routers as a ISDN gateways and Cisco VG224/ATA 186 as POTS gateways. While Cisco Call Manager collects call statistics from 7900 series SCCP handsets managed by the Call Manager (number of VoIP packets, dropped frames etc.), it shows only one side of the call as it does not collect statistics from the Cisco routers (configured as H.323 gateways), the Cisco VG224 (with ports configured as H.323 gateways and as a SCCP devices) and Cisco ATA 186 (configured for SCCP).
    Is the collection of these statistics possible? What needs to be done?
    Thanks,
    Paul

    Update: Logging of QoS/Call Management Records (CMR) to Call Manager CDR database is not possible with H.323 gateways; only MGCP gateways:
    http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_qanda_item09186a008020650a.shtml#qa4
    Anyone know how to get the Cisco router gateway to log these statistics anyway using standard router logging mechanisms (e.g. syslog)?
    Anyone know about calls to SCCP ports on Cisco VG224 or ATA 186?
    Thanks,
    Paul

  • Cisco Switches (2960 Series) Management

    We are managing these devices using HP OpenView Network Node Manager (Ver. 7.5) on HP-UX platform.
    What are the known problems, limitations on its initial discovery and on later stages of managing the same ?

    The Cisco Catalyst 2960 Series supports the Cisco IOS LAN BASE software image. This software image is a rich suite of intelligent services that is also available in a crypto image at no additional charge.
    Cisco Network Assistant also offers centralized management and configuration of Cisco switches and other Cisco devices such as routers and wireless access points. With Cisco Network Assistant, in addition to configuring multiple switches at a time, you can configure Cisco wireless access points, and invoke the Device Manager on Cisco routers and access points.

  • Cisco Unity Connection 8.X and Cisco UCS

    Hi
    We are in a planning phase for Unity Connection 8.X on Cisco UCS C-Series. The Cisco Unified Communications SRND 8.0 states that requires reserving one physical core per physical server.
    what does it really mean?

    See sample depiction below of applications and physical core usage on a server with 2 CPUs and 8 total physical cores. In white is the reservation of one physical core.
    Regards.

  • Cisco Prime 2.1 CLI-Template for Switch configuration Backup

    Hello everybody,
    I am trying to write a CLI Template in cisco Prime to save the running-configuration of our core switch to the FTP server, 
    I have already configured the FTP username and Password in the core Switch 
    ip ftp username cisco
    ip ftp password cisco123
    in Cisco Prime I have created a template as follow:
    copy running-config ftp: 
    $FTP_IP_addrress >> the FTP Server
    $name                    >> the name of file and the date
    After deploying this template on the core switch,
    I received Error Msg in Prime as follow:
    Error : Command returned an error : copy running-config ftp: 172.16.30.30 Run_Config_Core_19_2_2015 ^ % Invalid input detected at '^' marker. QAF-DC-4507-CORE(config)#
    I know that the backup files can be fetched directly from Cisco Prime in the Configuration Archives, But also I need to test if we can take a backup directly to the FTP server using Prime.
     Thanks in advance.

    Thank you Bkennedy for replying,
    I changed my template to be as follow:
    #MODE_ENABLE
    copy running-config ftp: 
    $Mgmt_IP_addrress
    $name
    #MODE_END_ENABLE
    but still I am receiving Error like :
    Error : Exception while sending interactive commands to device, Expect timeout: Failed to match expected device output due to Expect timeout current timeout 60000. Current output : Address or name of remote host []? Current expects : (DC-450.{0,30}|DC-4507-AGG)\([^\)]+\)#\s*\z DC-4507-AGG# 
    I believe that we have to tell the Prime how to send the variables to Switch, because the switch is waiting for the remote host IP address and the destination file name???

  • Need that a Cisco Catalyst Express 500 behaves as cheap switch

    Need that a Cisco Catalyst Express 500 behaves as  cheap switch.
    I happen to have a surplus of CE500 and i need to use one as a layer 2 cheap switch (unaware of lan and with port protection off).
    How can i achive this?

    That's the thing, i'm sitting on several CE500, i'm not allowed to buy a cheap one right now, i have to use what i have, i know is too much but it should work and i read that it does, there is only one problem, i need to plug a access point to the CE500 that connect this section of my network to the rest.
    I can't make the CE500 to work with this AP, a cheap switch i had there before worked properly.

  • NAC is not managing new Cisco Switch 2960S

    Hello,
    we want to add a Cisco Switch 2960S to the devices, but CAM says he is unable to control that switch.
    The switch type Cisco WS-C2960-8TC-L is already running on the CAM.
    Is there a OID Update for the 2960S?
    Our CAM version is 4.5.1.

    Solution:
    Use the update on CAM:
    -> Device Management -> Clean Access -> Updates -> Update
    to get new OIDs for the switches.
    This solved the problem. The device was added afterwards successfully.

  • How to show module and SFP information include hardware serial number on Nexus switch?

       How to show module and SFP information include hardware serial number on Nexus switch?                 Thanks.

    Hi,
    The show inventory command will give you details of the Nexus chassis, power supplies, Supervisor, Fabric, I/O modules (including FEX if you have them) etc. To get the details of the installed SFP/SFP+ then you'll need to use the show interface transceiver command.

  • Can use SFP-H10GB-CU3M to connect 6120XP to Cat6K Switch?

    Can use SFP-H10GB-CU3M OR SFP-H10GB-CU5M to connect 6120XP to Cat6K Switch?

    You dont have to connect to Nexus equipment. Your LAN can be anything as long as you can connect the UCS system to it.
    Currently you need a switch with 10GE ports to uplink from your 6100s.
    I believe that in the next version of the firmware/software in UCS you will be able to connect your 6100s to the LAN using 1G ports.

  • Cisco SFP GLC-LH-SM unknown in show interface status

    Hi all,
    Client installed a single mode fibre run from Distribution Switch to Access switch. The distance is not even greater than 100 Metres but the client insisted since the fibre is free.
    On the Cisco Catalyst 2960X-24TS-L (Access layer not stacked) the SFP is identified, but on the Cisco Catalyst 2960X-24TS-L (Distribution switch stacked) the SFP module is "unknown".
    access_sw#
    Gi1/0/49 access_sw po notconnect 1 auto auto 1000BaseLX SFP
    dist_sw#
    Gi1/0/49 dist_sw po notconnect 1 auto auto unknown
    Distribution switch is running 150-2.EX4
    Access switch is running 150-2.EX5
    I have configured on both sides speed nonegotiate, above output is showing that the 2 are not even talking to each other since their status is still auto auto...
    Any ideas is gladly appreciated in terms of what show commands or diagnostic tests I can do for the interface just to test it?
    I have tried to test it but it is saying diagnostic monitoring is not running, how can I run that feature as well?  Is that network impacting if I did?
    Kind regards,

    Hi,
    Is there a link light on either side of the connection?
    Is the SFP on the distro switch also LX?
    If there is no link light, try crossing the strands on one side of the connection and test again.
