Modulo GLC-T= en un Switch Catalyst WS-C3750G-12S-S

Buenos Dias,
Tengo problemas al usar un transceiver Cisco “GLC-T=”  en un Switch Catalyst WS-C3750G-12S-S:
Se conecta a un puerto libre de Fibra, el switch lo reconoce con “show inventory”, pero al conectar con patch cord de fibra a un equipo ni siquiera linkea
Pero cuando colocamos el transceiver a un Catalyst 2960 si funciona
Saludos.

Hi,
Can't really read much Spanish but from what I can read you are saying GLC-T does not work in WS-C3750G-12S-S but it works in 2960.  If that is the correct translation than on the 3750 you need IOS 12.1.(14)EA1 or later version installed.

    Thanks in advance!!

  • Cisco Switch Catalyst WS 2950C - 24

    Cannot connect to the above switch from my console port. Port not working. I don't have any I/P Address on this switch that I can Telnet into. Is there any way I can connect and setup an I/P Address??

    If you are running newer IOS, you can use express setup
    http://www.cisco.com/warp/public/473/express-setup.html
    But if console port is not responding and you are certain that you are using a good cable/settings, you will be better off replacing the switch.

  • GBIC error on Cat3750G-12S

    On a Catalyst WS-C3750G-12S (IOS Version 12.2(20)SE4) I just inserted 12 original SFP
    GBIC GLC-SX-MM purchased from Cisco.
    One of them gives the error below:
    May 11 16:17:21: %GBIC_SECURITY_CRYPT-4-ID_MISMATCH: Identification check failed for GBIC in port 65544
    May 11 16:17:21: %PM-4-ERR_DISABLE: gbic-invalid error detected on Gi1/0/8, putting Gi1/0/8 in err-disable state
    The Catalyst 3750 Switch System Message Guide says:
    "verify that the module was obtained from Cisco or a supported vendor."
    How is it possible that a original Cisco GBIC will be not recognized as valid ?
    Thank you, Regards
    Alessandro Asson

    So, in its infinte wisdom, cisco has made it so you can only use cisco (ok, not actually made by cisco, but branded as cisco) SFPs. I suspect that one of the SFPs you have didn't get the right prom burn before being shipped (or someone swapped a label and RMA'd a non-cisco SFP) or something similar. There are companies that will take an off the shelf Finisar SFP and burn the cisco code onto it so you don't need to pay the inflated cisco price.
    Cisco's policy on this has made me move to an alternate switch vendor (and I buy a LOT of switchports).
    You may or may not be able to skip the genuine cisco gbic test by doing:
    no errdisable detect cause gbic-invalid

  • Catalyst 2950 Switch flash_init error

    Hi Everyone,
    I'm new to Cisco products and have a small home lab set up. I have a Catalyst 2950 switch that I would like to restore to factory defaults. Here is the issue I'm having and can't figure out.
    I pull the power, telnet into the console port, hold the mode button and restore power. The boot loader (Version 12.1(11r) starts and says the usual message the system was interrupted prior to flash initialization (Paraphrasing here)
    I get to the switch: command line, enter flash_init. Flash states it initialized and then all I get is a < with an underscore under it prompt. Anything I try to type comes up as bizarre characters and I can not get back to a switch: prompt unless I reboot the switch manually. Unsure of what to do here.
    Thanks in advance!

    Hi mattymattlynch
    Check the workaround on the following documents:

    If no luck , the flash might be corrupted and requires a replacement.

  • Monitoring Catalyst Switch (MIB issue)

    Hello,
    I am trying to monitor Catalyst WS-C3750G-24TS-E switches with Openview NNM. Before being able to do this, I have of course to import the MIB in Openview in order to interprete the traps, MIB entries,... that I get from/look at the switch.
    In the Management part of the datasheet of the switch, there is a list of about 20 MIB's, does this mean that I have to import all these MIBs in NNM in order to be able to monitor the switch??
    (I have the same issue also for Catalyst WS-4506 Chassis, WS-X4548-GB-RJ45 48x10/100/1000T ports blade an for the loadbalancer CSS11501, but probably the response for the catalyst will respond also the questions)
    Best regards
    CB

    Thanx for your reply.
    In fact, the core functionning of SNMP traps, requests is clear for me, perhaps I was not clear enough on that :-). What I need to know is if importing a single MIB allows me to interpret all the information that I get from the switch(all the traps and gets) or do I need to import all the MIBs that are indicated in the whitepaper. I could imagine that most of the MIBs contain redundant information so there would be no need in importing them all, but I am not sure on this point.
    Thanx
    CB

    Hi,
    This could be related to L2 issues like a loop, see that the K2L2 Address Table R process has a target of   2.00% and is currently running at 72.93%, which is way over the expected target, this can be an indication of host/mac flapping issues. Also the host learning queue seems very high and the L2/L3 control.
    You can enable mac notification mac move command to see if on the logs are any flapping issues. Also below is a link which is very helpful when dealing with high cpu issues on 4500.

  • How can I run a packet sniffer on a Router or Switch

    I have on my network several router 1700 series and switches Catalyst 2950 and I want to know how can I run ethereal on those babies to monitore what comes and goes

    The two most common methods would be (the old way) insert a hub (not a switch) in-line between the devices withthe traffic you wish to monitor or (the new way, for Cisco anyway) using port mirrroring.
    A hub (not a switch) will repeat every pulse that passes on the line to the analyzer.
    Since finding a new hub these days is virtually impossible (even some of the things sold as hubs are really switches), the more common way, at least in Cisco environments, is to "SPAN" (aka Port Mirroring) the port of the device whose traffic you'd like to monitor.
    Here's the setup guide for a 2950:

    To use the SFP+ transceiver, SFP-10G-SR, in your X2 slot, you need to purchase a Cisco OneX converter,
    CVR-X2-SFP10G=.  This solution allows you to start the migration to the smaller form factor 10G transceiver being used on most of the newer hardware.
    Otherwise, you could use the standard X2 transceiver, X2-10GB-SR.
    Good luck!

  • Catalyst (3750 24 10/100/1000T) and (3750 12 SFP) Stacking Problems

    Dear all
    I'm having a very strange situation here (at least for me)
    we have 4 core switches
    2 x   WS-C3750G-24T-S Catalyst 3750 24 10/100/1000T + IPB Image
    and
    2 x   WS-C3750G-12S-S Catalyst 3750 12 SFP + IPB Image
    Stack configuration is done this way
    when the switches are powered on, the first two SFP core switches are seen as a single stack with the stack master LED turned green on the first switch
    the other two (24 10/100/1000T) switches have the RPS LEDs always green, mode cannot be changed, and cannot be accessed by Console connection
    but when the (24 10/100/1000T) are powered off, the first (SFP) switch in the stack reports that " Switch 3 and 4 has been removed from Stack "
    which means they are stacked but there's something wrong, because
    only the SFP ports are shown in the " Show interfaces status " , the ethernet ports of the bottom switches are not present !!!
    can you please tell me what's the poblem ?

    Dear Daniel
    Sorry for my delayed response but i was actually quite busy
    but the problem was actually in another sense
    the default profile for the Catalyst 3750 SFP is the Aggregate SDM Template
    while the 3750 10/100/1000 ethernet Switch Default SDM profile was Desktop profile
    so i had an SDM mismatch

    all i did was changing the default profile of the SFP switches into the Desktop Profile and problem was solved

  • Cisco Catalyst 2980G

    Hi all,
    I am currently studying for my CCNA and have acquired some cisco equipment to help me with this. One of the devices I have is a Cat 2980G 80 port but for some reason I am unable to connect to it via the console port.  All my other switches and routers connect fine except this device.  The power light shows as GREEN but the STATUS LED is solid AMBER. From what i have gathered from various sites is that the IOS is probably corrupt and unable to load.
    If I am unable to access the switch via CONSOLE, how can this problem be rectified if at all.
    Look forward to your help and advise.
    Regards
    John

      also be aware that a 2980G is an old Catos box not IOS   just in case you did not know.  I don't remember there being any difference in the console cables on the catos boxes except the real old 5500 series .   Even if it was corrupt it should dump you into rommon mode.   If it's corrupt and you can get the console to work this page may be of help.

  • Need Information about More ports Fiber Optic Switches

    Hiii Guys,
    I need information about which Cisco Switch consist more Fiber Optic Ports. I knew one model Cisco (WS-C3750G-12S-E) Catalyst 3750G-12S-12 Gigabit Ethernet SFP ports. But we can using this we can make stacking up to 9 devices. Even though I need more than 12 ports in single device. Could any one help me out in this.

    Hi Sayed,
    Please take a look at the 3560E-12SD:
    http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps7078/product_data_sheet0900aecd805bac22.html
    [edit] Sorry, didn't catch from the first post reading that you've considered stacking (the 3560 doesn't support stacking).
    For more than 12 fiber ports on a single device you'll need to go for the 4500 series with the appropriate modules:
    http://www.cisco.com/en/US/products/hw/switches/ps4324/prod_models_comparison.html
    Cisco Catalyst 4500 and 4500-E Series Line Cards
