WS-C3750X-48T-S 2 stack 'cannot session 2"

WS-C3750X-48T-S  2 stack 'cannot session 2"   Anyone seen this before?
switch#session 2
% telnet connections not permitted from this terminal
There are two switches in the stack.
line vty 0 4
 session-timeout 15
 exec-timeout 15 0
 logging synchronous
 transport input ssh
 transport output ssh

A show version will display the current IOS flavors on all the switches in the stack.
I too am having this issue though. I'm thinking it's because transport output ssh telnet needs to be enabled. But I don't want to let the switches have telnet out capabilities. 
Is there a way to get around this? Maybe force the switches to session between each other via ssh instead of telnet?

    I want to tag all native vlan traffic from this switch with the command :
    vlan dot1q tag native.
    I can't see this command on the command line interface. How can I reach this option ?
    Have I to pay something ?
    Thanks for your answers.

  • IPhone completely stacked - cannot even turn off

    I have had calendar sync problem for a long time. I removed iTune and reinstalled the latest version again. While I was trying to restore my iPhone hopefully to solve the sync problem, my iPhone was stacked. Right now, the apple mark appears on the iPhone and a timer (it's like an analog stopwatch) keeps moving (rotating). I cannot do anything. I cannot even turn off the iPhone. Can someone help? Do I need to run its battery out?

    I've had this problem as well. I can hold down the two buttons for 2 minutes and NOTHING WHATEVER HAPPENS!!! I've tried pressing them simultaneously, tried doing each one first before the other - etc. None of it works.
    It is simply impossible to turn my iPhone (1st gen, 16 MB) off. It just won't shut down. And since that is the standard instruction whenever anything goes wrong with the iPhone, it kind of leaves me stuck.
    So what on earth are you supposed to do IF THE DANG THING WON'T SHUT DOWN?????

  • Some websites duplicate their URLs in history stack; cannot return to their parent with a single keystroke or mouse click.

    On some websites, when I click on the left arrow or use the backspace key, the browser doesn't return to the parent URL. Looking at the list of currently-accessed URLs, the current URL is duplicated in the stack, so hitting back or left arrow just brings me back to the same (duplicated) URL. For instance:
    site x <= current page
    site x
    parent
    This just started happening recently (within the last two or three updates). It happens on several, but not all sites.
    Thanks!

    This can happen if there were redirects or otherwise forms submitted.
    In such a case you can hold down the mouse button on the Back button to open the tab history and select the entry that you need.

    Yes, as long as the 3750X have an IPBase or IPServices license (and supporting image).
    BTW, stacking the two causes StackWisePlus to revert to StackWise.

  • Can I Stack Switches with differents Part Numbers? Is it possible??

    Hi,
    I have a doubt, I need to buy 4 Switches Cisco 3750-X, but 2 with UTP/RJ-45 Ports, and 2 with STP capability.
    My question is, for example, Can I stack 2 WS-C3750X-48T-E and 2 WS-C3750X-24S-E??

    The only limitation of stacking different 3750X models is the feature set of the installed IOS.
    I.e.:  "The Cisco Catalyst 3750-X Series Switches with LAN Base feature set can only stack with other Cisco Catalyst 3750‑X Series LAN Base switches. A mixed stack of LAN Base switch with IP Base or IP Services features set is not supported."

  • High CPU usage - 3750 X stack

    Support Community
    We recently configured a stack of four 48 port 3750-x switches . We are noticing high CPU usage. "Hulc LED process" seems pretty high.
    This has coincided with VMware servers getting slow and non-responsive at times, perhaps a coincidence, not sure.
    Below I provided some outputs that might help to diagnose it
    Thanks

    Thanks to all for your replies.

    I was aware of the many ACLs however we used to have the same ACLs in a previous 3750G stack about 2 weeks ago and we never had this issue. I agree I need to optimize them and do somehing because it is reaching its max before the CPU starts processing them but I am not certain this is what is causing the issue.
    Nikolay,
    I am trying to understand "interrupts" with the analysis of the outputs I posted. Here is another output deom the link you provided. Please post your thoughts if you can.
    This switch also serves as a gateway(L3 role)  for many systems. Would it make sense to offload that responsability from this switch and let an actual router do it?
    Thanks
    Johnny

  • Downgrade 3750X w/ IP Base to LAN Base for Stacking

    I have a WS-C3750X-12S-S (IP Services) that I THINK I'd like to downgrade to LAN Base so I can stack it with a WS-C3750X-48T-L that is already LAN Base...
    Can I do this?  Any reasons I shouldn't?  Small environment, isn't much routing at all going on here...Thanks!       

    That is because it is not an image it is a license.
    However you will loose more than just routing abilities.
    so if i where you i would go the other way.
    I would buy a license upgrade to upgrade the Lan base to ip base instead.
    otherwise you will loose alot of functionality that you might want/need such as eem, powerstacking and so on.
    to buy a license to upgrade contact your local cisco rep.
    to change to a license from ip base to Lan base contact cisco licensing

    good luck

  • No valid license found after IOS upgrade on C3750x switch

    HI,
    Two switches below are working fine as a stack with IOS c3750e-universalk9-mz.122-55.SE5.bin & ipbase license.
    Switch#1 (Master, WS-C3750X-24P-S)
    Switch#2 (Member, WS-C3750X-24P-S)
    After IOS Upgrade to c3750e-universalk9-mz.150-2.SE7.bin, The stack was broken. Switch#2 didn’t recognise valid ipbase license with new IOS and came up with lanbase license instead. Therefore stack cannot be composed due to license mismatch between Switch#1 (ipbase) and switch#2(lanbase).
    I’m wondering why Switch#2 didn’t recognise ipbase license with new IOS even though IPASE is running well with previous IOS.
    Here is excerpt from “show version” with 15.x image on Switch#2.
    License Level: lanbase
    License Type: Default. No valid license found.
    Next reload license Level: lanbase
    Here is excerpt from “show version” with 12.x image on Switch Stack.
    License Level: ipbase
    License Type: Permanent
    Next reload license Level: ipbase
    Thanks
    Jeong

    Thanks guys,
    I have fixed the issue by configuring  'license boot level ipbase' on the member switch#2. The switch recognised IPBASE license well and joined the stack successfully.

  • Cannot create HTTP client Exception in Http -- XI -- RFC scenario

    Hi,
    We are testing Http --> XI --> RFC scenario
    While testing this scenario from RWB we are getting following error message in the SXMB_MONI logs:
      <?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
    - <!--  Call Adapter
      -->
    - <SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="1">

    Following is the info from the Trace:
      <Trace level="1" type="System_Error">cl_http_client exc = argument_not_found</Trace>
    We have tried following things:
    1. In SICF we made sure the /default_host/sap/xi/adapter_plain is active
    2. Applied SAP Note: 716739
    Any response will be greatly appreciated.
    Thanks,
    Paresh

    Hi UDO,
    Thanks for your reply. The error was gone when I tested again this morning. I am guessing it must be the SAP Note 716739 that we applied and might not have refreshed the cache.
    I am still intereseted in confirming what exacly fixed this issue.
    As per your suggestion, I looked at the left Nav bar and the error was at the "Call Adapter" step. Even in the log message it says the same. The reciever/interface determination and mapping were successfull. I could successfully test the scenario in the integration directory.
    Here is what the 716739 Note said:
    Symptom
    If you call the Integration Server from a sending Integration Engine (proxy), the following error message occurs:
    Category = XIServer
    Area = INTERNAL
    Id = CLIENT_CREATE_FAILED.
    In transaction SXMB_ADM, you used the Configure Integration Engine function to enter a URL of the type http://<host>:<port>/sap/xi/engine?type=entry instead of a URL of the type dest://<name>.
    Other terms
    SICF, SXMB_MONI, SXMB_ADM, XI
    Reason and Prerequisites
    You have configured the communication route from the sending proxy (Integration Engine) to the Integration Server using the URL of the type
    http://<host>:<port>/sap/xi/engine?type=entry and have saved the logon data on the Integration Server in the Service
    /sap/xi/engine (transaction SICF).
    A program error has occurred: the communication log is not correctly set when the HTTP client is set up.
    Solution
    The problem is eliminated with SAP_BASIS Support Package 2. To eliminate the problem, you can use an URL of the type dest://<name>, where <name>  refers to the name of a HTTP destination that you have maintained with transaction SM59.
    Now, I was not using the proxies but Http post to XI. Do you guys also think this might have fixed my issue?
    Thanks,
    Paresh

  • Compile error in drop out stack program

    I have a compile error "Cannot find symbol" Symbol: constructor Node(E, dropOutStack.Node<E> on line 20
    line 20 : topStackRef = new Node<E>(obj, topStackRef);
    import java.util.*;

           //Node class

                   return obj;
               public E pop() {
                         if (empty()) {
                        throw new EmptyStackException();
                   else {
                        E result = toStackRef.data;
                        topStackRef = topStackRef.next;
                        return result;;

               String[] items = {"Item1", "Item2", "Item3", "Item4", "Item5"};
               for (int i = 0; i < 5; i++) {
                    int itemNumber = nextInt(i);
                   itemStack.push(items[itemNumber]);     
               System.out.println(itemStack);
           

    Anyways. I need help with the logic. As far as I
    know, DropOut stacks cannot return something that has
    been poped or removed. if the operation (performed n
    times) is n+1 times.No empty stack can be popped, if that's what you're saying.
    If you examine your assignment, it describes special behavior for drop-out stacks during the push method. It says that stacks are made with a given size, and that when the stack is full, subsequent pushes cause the least-recently-pushed element to drop out.
    Your code doesn't do that. It does some futzing during pop whose purpose is unclear to me.

  • Stack ADT using array

    Hi everyone, I posted a similar question earlier and thought I got the response I wanted but I keep running into problems.
    I'm looking to make my own version of the stack ADT using arrays (or arraylist).
    I have created my own isEmpty() method. Here is part of my code:
    public interface StackADT<T> {
         void push(T element); // adds an element to the stack
         T pop(); // removes an element from the stack and returns it
         boolean isEmpty(); // returns true if the stack is empty and false otherwise
         T peek(); // returns top element from the stack without removing it
         void truncate(); // truncates the stack to the exact number of elements
         void setExpansionRule(char rule); // sets expansion to either doubling or increasing by 10 elements
    public class Stack<T> implements StackADT<T> {
              private T[] array;
              int index = 0;
              public Stack(){
                   this.array = (T[]) new Object[50];
              public boolean isEmpty(){
              if (index == 0){
                   return true;
              return false;
               public T pop(){
                    if(Stack<T>.isEmpty()){  //ERROR
                     throw new EmptyStackException("Stack is empty");     
    }I'm trying to use my isEmpty() method (also part of the stack class) inside other methods like pop(). Problem is it says: "T cannot be resolved to a variable, Stack cannot be resolved to a variable". I also tried Stack.isEmpty(), but it doesn't work. I'm really confused. Any suggestions?

    No - you haven't. There is no 'isEmpty' method in the code you posted.
    We can't debug code that we can't see. You haven't posted any interface and you haven't posted anything that calls any of the limited code that you did post.
    You did post code that tries to call the method on the class instead of an instance of the class.

  • C3750X get power supply errors

    Hi, I got a problem with some phones connected to a C3750X-48PS. Phones are Polycom SoundPoint 560. Ports most critical: gig 1/0/9 & 1/0/31.
    Actually, the C3750X belongs to a stack, with the IOS: 12.2(55)SE3.  The environment conditions: power supply working ok, temperature level: ok. (show env all). Physically the LEDs are in green, and the room does not have temperature issues.
    Also, the phones present a humming noise (high pitch). The noise keeps happening even if the phones are plugged in other ports of a stack. It was attempted to connect the phones directly to the stack ports instead of the ports in the cubicules, and the issue keeps happening.
    The Stack presents also sudden fan to spin up / spin down for a couple of minutes, and within a couple of minutes from working on and off.
    Customer has another facility with the same switches but with IOS12.2(55)SE1, in there the same phones were tested and they are working fine.
    A reboot was performed, but now the C3750X show these messages:
    %ILPOWER-3-CONTROLLER_PORT_ERR: Controller port error, Interface Gi1/0/9: Power Controller reports power Tstart error detected
    %ILPOWER-3-CONTROLLER_PORT_ERR: Controller port error, Interface Gi1/0/31: Power Controller reports power Tstart error detected
    Thanks!

    I've found it!  In case anyone is wondering, a lot of server information is available by querying with the iLO xml tag "GET_EMBEDDED_HEALTH".
    This returns, buried way down in the results, information about power supplies (section POWER_SUPPLIES).
    While there doesn't seem to ask for just information on the power supplies, this works!

  • C3750X which IOS image?

    Hello,
    this week, I received a pair of C3750X-48T-S switches.While checking for the best IOS Image, I found many bug reports and reports of instable devices with IOS 15.0.2. The most stable and bug free IOS apparently is the 12.2.55 one.
    However, the 12.2.55 train will be end of life soon:
    http://www.cisco.com/c/en/us/products/collateral/switches/catalyst-3750-series-switches/eos-eol-notice-c51-731425.html
    Which IOS would you guys recommend me to use in a fresh installation? 12.2.55-SE9, 15.0.2-SE6 or a totally different one?
    Thanks a lot in adavance,
    Michael

    Usualy IOS to be discussed with your account team as they would be the best person to define which one is the best for you rnetwork based on the products and services you are running on.
    Anyways we are seeing the stable version on this platform to 15.0.2-SE6(ED)  you can go ahead and use this firmware.
    Download is available on the link mentioned below:
