Cisco catalyst 4500e rebooted unexpectedly

Dear team,
we are facing problem in cisco catalyst switch, actually we are using Cisco catalyst 4500e switch, Two month back we upgrade IOS from "cat4500e-ipbasek9-mz.150-2.SG" to cat4500e-ipbasek9-mz.152-2.E1.bin “since i upgrade new IOS that  was running perfectly,  but last two weeks back unexpectedly switch was rebooted and today also we faced the same problem. here i enclosed the tech support details. kindly check and suggest me the correct solution. 
  Is there in any bug is there?...... How can we clarify whether the switch is ok on that IOS.....
 please suggest me the right IOS image for my cisco catalyst 4500e switch

Hi Ashok,
Looks 15.2.2E2 has the fix. you could try upgrading to it.
Hope this helps.
Please do remeber to rate all useful posts.
Thanks,
Madhu.

  • Cisco Catalyst 4500X

    I want to buy Cisco Catalyst 4500-X-16SFP+ and upgrade the license to Enterprise service. But license description show "IP Base to Ent. Services license for 16 Port Catalyst 4500-X". Is it means that only 16 port is Enterprise Service? If I add more 8 Ports module ,can it use Ent Service?
    Please kindly advise.
    Thanks,
    Mano

    Is it means that only 16 port is Enterprise Service?
    The license is in blocks of 16- or 32 ports.  Let's say you purchase an Enterprise license for 16-ports and you got an optional 8-port module.  You purchase an additional license of "C4500X-16P-IP-ES" and this allows you an additional 16-ports of license.  You can't purchase a license for only 8 ports.

    It occured several times before 11/17 and I have tried to reseat the module before, but the IDSM2 reboot again. The IOS version of supervisor engine is s72033-ps-mz.122-18.SXD5.bin, The IDSM2 software version is 6.0(5)E2. Please help to diagnosis this problem. Shall I upgrade IOS of supervisor engine or IDSM or need RMA?
    Best Regards,
    Jackson Ku

    Agreed, this likely needs to have a TAC case opened for an RMA -- especially if a re-seat of the module has already been attempted.  Any time you're seeing the switch cut off power to the module over multiple insertions, that's not a good thing.
    I just had this happen to a FWSM last week, and re-seating the module didn't work for me, either.
    You can read more about the error message here:
    http://www.cisco.com/en/US/partner/products/hw/switches/ps700/products_tech_note09186a00801b42bf.shtml
    WorkaroundA simple reseat of the module corrects this issue 90 percent of the time. If you reseat the module, it realigns the switch fabric and ensures a firm connection to the backplane.

  • Cisco Catalyst 3850 as ntp master

    Hi All,
    I have 2 x Cisco Catalyst 3850 stacked together. What are your recommendations if I use the C3850 as a ntp master for all edge switches connected in my network? All edge switches must be authenticated if it needs NTP sychronization. But other than that, what are the downsides?
    For example,
    1. I heard that switches do not have an internal clock so is a poor device to be a centralized NTP master.
    2. I have also read that switches also have slow CPU processors that may lack the processing required.
    3. Its NTP sychronization will use external NTP servers which are resolved into IP addresses (e.g. pool.ntp.org). IP address can change. What other more reliable NTP sources are there?
    4. Any other thoughts and comments are most welcome.

    Firstly, DO NOT use the command "ntp master".  Cisco do not recommend using this commands because this will confuse the NTP propagation inside the network.  
    Next, all Cisco devices do not have a dedicated clock.  All appliances need to get SNTP/NTP time synch from somewhere.  This "somewhere" could either be a dedicated GPS-based NTP server and/or a time synch somewhere out in the internet.  
    You can also use the command "ntp update-calendar".  This new command allows appliances to take regular "snapshot" of the time and save it into the NVRAM.  In case there was a reboot or a power failure, the appliance's time is not too far away instead of waiting 5 to 10 minutes for SNTP/NTP to synch.

  • I cannot connect by console port to Cisco Catalyst 3750 using ethernet to USB.

    Hello. I have one Cisco Catalyst 3750 switch, and two 2950 switches. I am trying to reset their settings using a console cable with a trendnet Ethernet to USB adapter. When I try loading hyperterm or putty on com3 there is no signal. I have the communication port setting on com3. I don't know what the old settings are, and they can be reset. I get connectivity lights when plugging the cable into the switch ports. What am I missing? 

    Are you definitely using the correct COM Port number? On Windows7 Right Click My Computer > Manage Then select Device Manager and expanPorts (COM & LPT)d  in my case is shows Prolific USB-to-Serial Comm Port (COM5). 
    Once you have the right COM Port number just use the default settings in Putty. You may find the COM Port is locked up which will require a reboot.

  • T400 is rebooted unexpectedly

    Hello there,
    I have a problem with T400 that the laptop is rebooted unexpectedly when I try to logon Windows(at GINA). It's rarely happened. Once it's happened. It become I can not use my Windows account with a message like "You can not use this computer with this account, Please use other computer". It's in Japanese so It will not be properly translated. 
    After several hours, I can use the Windows account.
    Before shutdown PC manually, USB memory(ReadyBoost) was connected to the laptop. But, I'm not turned on readyboost on USB memory.Anyway I guess It might be a caused.
    My environment is below;
    T400
    BIOS:7UET93WW(ver. 3.23)
    Intel WiFi Link 5100 AGN(Driver ver.14.2.0.10)
    TPM 1.2
    Windows 7 Professional(Japanese) SP1 + latest hotfixes
    CSS 8.3
    Does someone know about this problem? Please help me.
    Sincerely,

    hey sbux0007,
    the T400 of yours, does it have one user account or 2 and is it being use in an office network? I normally stumble across >> "You can not use this computer with this account, Please use other computer" .. when it is a system that has two user accounts and when the computer is set to use with a network.
    since this rarely happens it is hard to pinpoint what is causing this. what i suggest would be that you keep an eye and make notes of what programs that you were using before the sudden reboot.

  • Connection of LC/APC fiber patch cords to Cisco Catalyst 6500 $ Cisco Access 3750 Switches

    I have an LC/APC fiber patch cord infrastructure and I want to connect it to Cisco Catalyst 6500 & Cisco Access 3750 Switches. what type of transceiver should be used?
    I read a note on Cisco website stating the following for Cisco SFP+ transceivers:
    Note: "Only connections with patch cords with PC or UPC connectors are supported. Patch cords with APC connectors are not supported. All cables and cable assemblies used must be compliant with the standards specified in the standards section"

    Thank you,  but my question is that I have a single mode fiber patch cord with LC/APC connector while cisco stating a note that only use LC/PC or LC/UPC type of connectors with SFP+ transceiver.  
    So what type of transceiver should I use to connect LC/APC patch cord to cisco switches?  Is there another type or SFP+ still can be used? 

  • Cisco Catalyst 2955 Causes Some Devices to "Die" During Boot

    I posted this question in the LAN section of the forums, but I realize this is probably the proper forum for my question.
    I have recently purchased a Cisco Catalyst model WS-2955C-12 switch. During POST (boot), the console reports that the switch undergoes what is known as a "FRONT-END LOOPBACK TEST". During this test the 14 port lights on the device light up amber for a moment, connectivity is lost, and after a second or two the lights go off and connectivity returns. We've found that the moment the lights go off at the end of this test, if we have a specific device (with a specific ethernet chip) directly connected to the switch the ethernet chip is adversely affected by this test - the device "goes dark" and is not capable of communicating with anything (including other switches, routers, etc...) until it is power-cycled. What exactly does this FRONT-END LOOPBACK TEST do (I know it's for validating the ports for hardware defects), and what does it send across the wire that could be causing my ethernet chip onboard the device to go bonkers?
    Thanks!
    -Danny

    The ethernet chip on the device (the device is a National Instruments product) is an STMicro STE10/100E, and I'm fairly confident I now know what's happening but I don't know why.
    When my ethernet chip is in Autonegotiate mode, the "FRONT-END LOOPBACK TEST" performed by the catalyst does something where, at the conclusion of the test, the ethernet chip goes into an autonegotiation state and never comes back out of it. I'm thinking the "FRONT-END LOOPBACK TEST" is sending something across the wire that's confusing this specific ethernet chip; I've tried 3 Intel parts and also a Broadcom part and they rode it out in autonegotiation mode just fine. If I put the STE chip into a manually-configured mode the "FRONT-END LOOPBACK TEST" doesn't cause it to "go dark".
    So, my question is really what does the FRONT-END LOOPBACK TEST do? Does it perform a remote loopback test (the STE10/100E doesn't support loopback tests)?
    -Danny

    Hello NetNavi.
    Check the post above about MacSec for more information and let me know if you need further clarification, if so I will do my best,
    In regards to best practices there is a Cisco document; it describes deployments and best practices in every scenario; Supplicants, authenticator, authentication services and other configurations. Please check it out:

    In regards to Private VLANS:
    What is a Private Vlan?
    A private Vlan is a way to isolate hosts within the same Vlan or broadcast domain. So even when you might have devices sharing the same broadcast domain they can be isolated, this isolated is configured based on sub-domains also most often called primary and secondary Vlans.
    What is a primary Vlan?
    The primary Vlan is representation of the private Vlan, a primary Vlan has one or more secondary Vlans, a switch uses the primary Vlan to present traffic from the secondary Vlans to its neighboring devices.
    What is a secondary Vlan?
    A secondary Vlan is a sub-domain of the primary Vlan. We could say that the secondary Vlans belongs to the primary. The must be associated to a primary Vlan. There are two types of secondary vlans: Isolated and Community secondary Vlans.
    What does it happen to host within a secondary isolated Vlan?
    Host within the isolated vlan; can’t communicate to neither other host in the same isoalted vlan nor host in a community vlan.
    What does it happen to host within the secondary community Vlan?
    Host within the community Vlan can communicate with other host assigned to the same community vlan, but they can’t talk to host in other community vlans.
    What are the benefits of implementing private Vlans?
    Scalability: The most common scenario is a service provider. Imagine all customers of a service provider connected through DSL, cable modem… it’s very likely that all customers belong to the same broadcast domain, however if that’s the case why is it that I can’t use my neighbor’s printer, or maybe why is it that I can’t access the files he has store in his computer, (security) we are in the same broadcast shouldn’t I be able to at least ping his ip address?. Well that’s because the ISP must guarantee some type of security for their customers, and because put every single customer that they have in a single Vlan is not scalable they use private Vlans.
    Examples:
    ISP use private vlans to protect from security bridges, Private vlans and isolated Vlans are used to protect personal information for example from one customer to another.
    DMZ; Many implementations utilizes private vlans in a DMZ to limt or minimize that risk of a compromised server.
    I would like to share this documentation with you for further information and configuration guidelines

  • Alternative switch to Cisco Catalyst 3750v2-24FS and 3750-24FS

    I`m looking for an alternative to these two switches:                 
    1.  WS-C3750V2-24FS-S  Cisco Catalyst 3750V2-24FS Switch with 24 100FX SFP + 2 Gigabit Ethernet SFP Ports
    2. Cisco Catalyst 3750-24FS (WS-C3750-24FS-S 100BASE-FX)
    They are now EOL and not available.
    I have a campus style network and need to be able to connect multiple 100FX fibre switches back to a central switch. The 1st unit uses 100FX SFP modules and the second has in-built 100FX ports. I`m struggling to find anything from Cisco that will give me multiple (i.e 12+) 100FX ports.
    Could anyone please point me in the right direction?
    Many thanks,
    Paul

    Hi Paul ,
    Replacement for both switch is WS-C3650-48TS-S.

  • Debian Linux Bonding and Cisco Catalyst 3750 - best practise?

    Hello everybody,
    I would like to know what's best practice to do this:
    The two NICs of a Debian Linux server wants to be connected with two Switchports of a Cisco Catalyst 3750 switch(stack). My goal is to have load-balancing and failover.
    My /etc/network/interfaces looks like this:
    iface bond0 inet static
           address 192.168.0.30
           netmask 255.255.255.0
           network 192.168.0.0
           broadcast 192.168.0.255
           gateway 192.168.0.1
           dns-nameservers 192.168.0.10 192.168.0.20
           dns-search xyz.mycompany.com
           slaves eth0 eth1
           bond_mode ???
           bond_miimon 100
           bond_downdelay 200
           bond-updelay 200
    First question: What bond mode should I use?
    The switchports looks like this:
    interface GigabitEthernet3/0/4
     switchport access vlan 20
     switchport mode access
     spanning-tree portfast
    What changes are necessery here? Something like this?
    interface GigabitEthernet3/0/4
     switchport trunk encapsulation dot1q
     switchport mode trunk
     spanning-tree portfast
    Thanks a lot for suggestions, hints, etc.! :-)

    Hi Michael,
    thanks a lot for your answer - and sorry for my late reply!
    I like to show you my solution - I hope that it is a solution. ;-)
    My config on the switch(stack):
    switch#show etherchannel summary
    Group  Port-channel  Protocol    Ports
    ------+-------------+-----------+-----------------------------------------------
    2      Po2(SU)         LACP      Gi3/0/3(P)  Gi4/0/3(P)
    switch#show running-config interface GigabitEthernet 3/0/3
    Building configuration...
    Current configuration : 172 bytes
    interface GigabitEthernet3/0/3
     description myserver, eth0
     switchport access vlan 20
     switchport mode access
     channel-group 2 mode active
     spanning-tree portfast
    end
    lansw01#show running-config interface GigabitEthernet 4/0/3
    Building configuration...
    Current configuration : 172 bytes
    interface GigabitEthernet4/0/3
     description myserver, eth1
     switchport access vlan 20
     switchport mode access
     channel-group 2 mode active
     spanning-tree portfast
    end
    switch#show running-config interface port-channel 2
    Building configuration...
    Current configuration : 82 bytes
    interface Port-channel2
     switchport access vlan 20
     switchport mode access
    end
    The /etc/network/interfaces of my Debian machine looks like this:
    auto lo
    iface lo inet loopback
    auto bond0
            iface bond0 inet static
            address 192.168.1.xxx
            netmask 255.255.255.0
            gateway 192.168.1.xxx
            dns-nameservers 192.168.1.xxx
            dns-search xxx.xxx.xxx
            bond-mode 4
            bond-miimon 100
            bond-downdelay 200
            bond-updelay 200
            bond-lacp-rate 1
            slaves eth0 eth1
    This setup seems to work well. But I'm wondering that there is nothing with "trunking" in my setup. Would you like to give me your opinion about this?
    Thanks a lot and many greets
    Stephan

  • 802.1x on Cisco Catalyst 2960

    I am trying to enable 802.1x on one of

    System image file is "flash:c2960-lanbasek9-mz.122-25.SEE4.bin"
    According to Cisco, this image supports
    802.1x. Why can't enable it at the
    interface level?
    Can someone help me out? Thanks.

  • Cisco catalyst 2960 booting garbage, help on restore IOS

    Dear All,
    This is my first time on terminal access of Cisco Catalyst 2960 (2960TC-L), normally would use the web configuration for most task.
    Now the switch has an issue with the web interface and when I try to access through terminal, I was greeted with garbage upon the booting of the switch, I searched for the terminal boot process and it wasn't what I was expected for my switch. I was a bit dumbfound now of how can I recover the firmware to its default stage, now that I cannot even boot through its terminal console.
    Any help is highly appreciated. Thank you for your time.

    Hi,
    I just verified with my colleague of whom have done quite a few bits before I took over his task.
    His reply was he actually did an IOS flash before, though I'm not sure how he did it, but according to him, it was actually a success and the web interface still works for few times before it become like this.
    As I tried another time to goes into root mode (or Admin mode??) for the switch, the steps as I performed below:
    1. Refer to cisco-2960-putting-setting.jpg for the settings. I press Open and it does display the console Window, no issue there.
    2. I hold the "mode" button on the switch and turn on the switch power, and after few seconds the screen display as such (refer to cisco-2960-putty-output2.jpg), the SYST L.E.D. did flash with following pattern: Green (blink ~15 times) then Orange-Green (repeat blink twice) then Green (stable light), for this I was expecting it to goes off after few seconds but it didn't, I wait about a minute before I let go the "mode" button.
    3. After I let go the "mode" button, it goes to the screen (refer cisco-2960-putty-output3.jpg), and the SYST still blinking, possibly infinitely... with the console output screen stays like that... and whatever I entered display weird/garbage characters instead, I can't do anything on it.
    Each tries display different weird characters, as the SYST still blinking infinitely.
    I'm unsure if I'm giving enough details for online troubleshooting, I'll try my best to give as per instructed.
    Thank you for your time.
