Setting uplink port on Catalyst 2900 series Switch

Greetings, I'm working on my CCNA and I want to copy down the IOS to my Linux box via TFTP before making any major configuration changes (basically back it up).
I've noticed I don't have an uplink port on the Switch and not really sure how to go about this.
Also can I use CAT5 or will I have to use Cross-Over?
thanks

As long as the speed and duplex are set to auto then MDI/MDI-X is enabled.
[/quote]
I'm not sure how to confirm if MDI/MDI-X is enabled or not on the Switch.
Forgot to include this other detail.  All of the devices (Linux pc and Cisco Switch) are connected to a Linksys SOHO Router/Switch.  Will this make a difference?  I wouldn't think so as long both devices can ping each other.
thanks

  • Psecure violation in 2900 series switch

    Hi,
    could any one plz tell me the reason for pseure violation.
    m using 2924 model switch with ver 12.0(s)wc17, how can i configure errdisable recovery commands in this switch?
    In this switch Errdisable recovery option is available only for  "udld" but not for  "psecure violation". How can i rectify this psecure violation problem
    in cisco 2900 series switch?

    hi
    By default the port security any violation happed it automaticaly the port goes shutdown state
    here some examples for configuring port security
    Switch(config)# interface FastEthernet1/0/1

  • How to remove the WiSM2 from the Catalyst 6500 series switch?

    Hello, can you explain to me how to safely remove the WiSM2 from the Catalyst 6500 series switch?
    According to the documentation "Catalyst 6500 Series Wireless Services Module 2 Installation and Verification Note":
    To remove the WiSM2, perform these steps:
    Step1     Shut down the module by one of these methods:
    In privileged mode from the router prompt, enter the hw-mod module mod shutdown command. NoteIf you enter this command to shut down the module, you must enter the following commands in global configuration mode to restart (power down, and then power up) the module:
    Router# no power enable module modRouter# power enable module mod
    If the module does not respond to any commands, press the SHUTDOWN button located on the front panel of the module.
    Step2     Verify that the WiSM2 shuts down. Do not remove the module from the switch until the POWER LEDis off.
    But, in the case of Step1 (1st methods) I do not see a option "shutdown"  in the command "hw-mod module 3"...
    All I prompted to enter is:
    c6500#hw-module module 3 ?
    boot           Specify boot options for the module through Power Management Bus control register
    reset          Reset specified component
    simulate  Simulate options for the module
    Is it hidden options? IOS version of c6500 is 12.2(33)SXJ1
    In the case of Step2 (2nd methods) there is not any button on the front panel of the module?
    And yet, it is better to remove the module configuration manually or use the command module clear-config prior to removing the module?

    Good catch.
    Which one is true, will get back to you on this if i've something soon.
    http://www.cisco.com/en/US/docs/wireless/module/wism2/installation/note/WiSM_2.html#wp34727
    The above link is procedure to remove wism2. This procedure doesn’t look like wism2 is hot swapable.
    http://www.cisco.com/en/US/docs/wireless/module/wism2/installation/note/WiSM_2.html#wp34621
    All modules, including the supervisor engine (if you have redundant supervisor engines), support hot swapping. You can add, replace, or remove modules without interrupting the system power or causing other software or interfaces to shut down. For more information about hot-swapping modules, see the Catalyst 6500 Series Switch Module Installation Guide.

  • Unable to hard code the ports of cisco 3750x series switch

    hello,
    I have tried with hardcode to 1000 7 Full on the ports which are connected to another switch.
    After changing the port to auto from one side of the switch port came up. Is there any solution to make port up when both sides are hard coded to 1000 & full duplex.
    Simple Words:
    Switch 1 --> Switch 2 --> Hard coded to 1000 & Full --> Down.
    Switch 1 --> Switch 2 --> Auto on one end to Switch 1  --> Up.
    Switch model:
    Switch 1 Cisco 3750x (Gi Switch)
    Switch 2 Cisco 3750 (Gi Switch)

    Yes, it's possible without a straight through cable, enable auto/auto both sides.    Otherwise you'll need a cross-over cable.
    BTW, if your standard is hard coding copper gig ports, for speed and duplex, you might consider bringing your standard up to date.  Copper gig standard went much further in how auto/auto is supposed to work.  By disabling auto/auto, I believe, you're also disabling some error monitoring too.  Generally, all the major players, e.g. Cisco, would recommend auto/auto for copper gig Ethernet.

    An uplink port doesn't necessarily run at wire speed but it is more likely to.
    But this doesn't mean you don't get oversubscription from the switch to other switches.
    It's quite a big subject to cover but i'll try and keep it brief.
    Internally within a switch there is a crossbar switch fabric which I think we covered before. Think of it of as pathways between ports. On any switch there are a number of ports that are capable of certain speeds.
    Put simply if you take the number of ports on the switch and multiply that by the fastest speed the ports can operate at, if that number is greater than the switch fabric then the switch is said to be oversubscribed.
    It doesn't mean in practice it will be oversubscribed but the potential is there.
    What can happen though with oversubscribed switches is that the uplinks ports are guaranteed not to be oversubscribed ie. they do not need to contend with the other ports on the switch. It's complicated but it is to do with the connectors per port group etc. to the switch fabric.
    But even though the uplinks ports can run at wire speed so they are not oversubscribed, if they are uplinks to other switches there may very well be more traffic combined from the other ports on the switch to that uplink port so you still get an oversubscription ratio.
    But what would make it a whole lot worse was if your uplink port was oversubscribed within the switch as well.
    So there is oversubscription within the switch and this is where we talk about ports running at wire speed or not and then there is oversubscription between different layers of the network eg. access to distribution for example.

    Hi Noob,
    On some kit like netgear hubs etc, you may find a little button or
    slider switch which may be labelled MDI or MDI(X) this allows a
    straight cable to be used between 2 Hubs or switches (Both DCEs).
    Some Cisco switches/routers will allow you to do the same but in software
    interface fastethernet 1/0/1
    mdix auto
    ====================================
    DTE devices like say your laptop PC NIC card has an MDI (Medium Dependant Interface).
    Physically this wires out as ( For 10/100M):-
    RJ45 PIN
    1  -- TRANSMIT +ve
    2  -- TRANSMIT -ve
    3  -- RECEIVE +ve
    6  -- RECEIVE -ve
    DCE devices like hubs & swiches have MDI-X (Medium Dependant Interface - Crossedover).
    Physically this wires out as ( For 10/100M):-
    RJ45 PIN
    1  -- RECEIVE +ve
    2  -- RECEIVE -ve
    3  -- TRANSMIT +ve
    6  -- TRANSMIT -ve
    So lets connect the device together with a STRAIGHT cable ( Function DTE to DCE)
    PC/NIC = DTE = MDI                                SWITCH = DCE = MDI(X)
    RJ45 PIN                                           RJ45 PIN
    1  -- TRANSMIT +ve -------------------------------- 1  -- RECEIVE +ve
    2  -- TRANSMIT -ve -------------------------------- 2  -- RECEIVE -ve
    3  -- RECEIVE +ve --------------------------------- 3  -- TRANSMIT +ve
    6  -- RECEIVE -ve --------------------------------- 6  -- TRANSMIT -ve
    So we transmit from the DTE and receive on the DCE and vice versa (BINGO).
    Remember Routers are regarded as DTEs
    =================================
    So lets connect 2 switches  together with a CROSSOVER cable ( Function DCE to DCE)
    UPLINK to UPLINK
    SWITCH = DCE = MDI(X)                           SWITCH = DCE = MDI(X)
    RJ45 PIN                                           RJ45 PIN
    1  -- RECEIVE +ve -------------------------------- 3  -- TRANSMIT +ve
    2  -- RECEIVE -ve --------------------------------- 6  -- TRANSMIT -ve
    3  -- TRANSMIT +ve ------------------------------ 1  -- RECEIVE +ve
    6  -- TRANSMIT -ve ------------------------------- 2  -- RECEIVE -ve
    So we transmit from the DCE and receive on the DCE and vice versa (BINGO).

  • Cisco Catalyst 3750-X or 3560-X Series Switches

    Recently, our company was deciding to buy Cisco switches, but they just tell the requirements and I finally focused on two kinds of switches, Cisco Catalyst
    3750-X or 3560-XSeries Switches? Who can tell me, tnx in advance.

     As I read a blog recently, it listed the specific differences between Cisco 3750-X and 3560-X, except for the common features of Cisco 3750-X and 3560-X, Cisco 3750-X can also offer-- Cisco StackPower technology: An innovative feature and industry first for sharing power among stack members; 
    Cisco StackWise Plus technology for ease of use and resiliency with 64 Gbps of throughput; 
    Investment protection with backward compatibility with all other models of Cisco Catalyst 3750 Series Switches. 
    And made a more detailed comparison between the two products, for ur reference.

  • Password reset on a Cisco Catalyst 3550 series

    We have a Cisco Catalyst 3550 series, and we don't have the password to gain access to the switch through a web browser. My question is if I reset the password using Hyper-terminal, does changing the password affect any vlan or fiber optic settings that I should know about. Or does resetting the password changes our switch to factory settings? 

    Hi,
    The password recovery procedure for your switch is described in this document:
    http://www.cisco.com/c/en/us/support/docs/switches/catalyst-2950-series-switches/12040-pswdrec-2900xl.html
    If you follow the instructions in the document exactly, you will retain the original configuration - you just rename the configuration file so that it is not loaded when the switch boots up. However, you will still be able to display it after the switch boots up using the more flash:config.old . Eventually, you can even load it into running-config using copy flash:config.old running-config command. At that point, the old passwords will be brought back but because you already are in the privileged EXEC mode, you can change them and save the updated configuration.
    VLANs should not be affected as long as you do not delete the vlan.dat file located in FLASH. Fiber optic ports should not be affected as long as you are using original Cisco GBICs. If you're using 3rd party GBICs, it may be necessary to enter the service unsupported-transceiver hidden command in the global configuration mode before they get recognized.
    Good luck!
    Best regards,
    Peter

  • SCVMM2012r2 UR3 : Even with no Virtual switch assigned, an uplink port profile remains

    Hi,
    What I'm tryng to do, is to unassign an uplink set on my host, set to the wrong NIC (actually, on 3 NIC, event if I specified 2 when I added the logical switch...).
    To proceed, I deleted the Logical Switch assigned in the host properties on Virtual Switches tab.
    On my host, the teaming has been deleted, but unfortunately, on one of my NIC, the subnet set in my Logical Network subsit in "Logical Network Connectivity" and is greyed out.
    It's said "The subnet an VLAN information is set by an uplink port profile set 'tVMNet' associated to this host an cannot be changed here".
    But, if I removed the virtual switch, how can it be?
    Thanks for any advice, I'm stuck

    Hi all,
    I did finaly remove the cluster from SCVMM and added it back, and it's working now. No more ghost config remaining.
    I'm working on SCVMM from 3 days now, and I'm really not sure that's the easy to use tool we need to manage our small private cloud... It's buggy, slow, oposite of ergonomic and far too much cloud provider oriented...

  • Catalyst 2960 uplink ports

    Hi,
    is there any difference between uplink ports (using 1Gbps SFP) and any another 10/100/1000 port on Catalyst 2960X ?  What I mean is: if uplink port has a 1Gbps SFP and considering that standard port are 10/100/1000, is there a reason, for example related to Catalyst internal hardware and bus architecture, that should make me connect a server to the uplink port instead to any another port ?
    Thank you a lot,
    enrico.

    Although you can purchase Copper SFP's, people generally use the SFP ports on a switch to connect fibre cables to which means they they get the full 12/24/48 ports for their hosts.
    Using one or more of the standard ports for uplinks means there are less for hosts but if you have spare and don't want the cost of running fibre and purchasing additional SFP's then use the normal ports.

  • Catalyst 2950 Series - Monitoring Port

    Do the catalyst 2950 series have a port that can be used to connect a device that is designed to monitor all traffic on the switch - we are looking to install Webspy to track network & internet usage. The Sentinal product would best be connected to the switch where it can record all traffic - it needs a monitor port or some such equivalent.

    Hi,
    The 2950 does indeed support that - the functionality is called Switch Port Analyzer (SPAN). The following link has details on how to configure it:

  • Port Security MIB on SF, SG series switches

    I need to setup some parameters related to port security features on my SG, SF series switches via SNMP. I've found that it is possible with port security MIB (1.3.6.1.4.1.9.9.315). I found out my devices has support of this MIB downloading archive with MIBs from cisco site. But when I try to read some parameters from this MIB via SNMP, for example "cps if port security status" (1.3.6.1.4.1.9.9.315.1.2.1.1.2) device answers with: "No Such Object available on this agent at this OID". But it is possible to do with web-interface in Security->Port Security section
    How is it possible to read/write such type of parameters ?

    The OID you mentioned cpsIfPortSecurityStatus has Read-Only permissions and hence you cannot set anything.
    You can only poll this object to know the operational status of the port security feature on an interface, which will result from one of the three status :
    1 : secureup
    2 : securedown
    3 : shutdown
    For more details check OID Translation.
    You can only set values which has Read-Write permissions, like cpsIfPortSecurityEnable, using which you can enable port security on an interface.
    Tell us what you want to achieve using SNMP Set operation?
    Also, I am not sure if these MIB features are completely implemented on 29xx/35xx/37xx devices.
    But are present in 45xx and 65xx series switches.

    but I need more detailes like IOS 12.3(7)JA for Aironet 1300 http://www.cisco.com/en/US/products/ps5861/products_configuration_guide_book09186a00804ebd50.html
    Regards

    I'm afraid there is not such document for IOS 12.2(25)FY since the Catalyst Express 500 Series switches are manageable through the GUI Device Manager or Cisco Network Assistant.
    I have also found key features and standards supported for that release:
