Force Switch Port LED to Blink

Hi Guys,
Does anyone know if there is a method of forcing a non connected switch port LED to blink for a certain number of times regardless if there is anything connected.
The purpose of this is we have remote 3750 switch stacks and quite often have to tell non technical staff to patch to a certain port. It would be much easier if we could say "Connect it to the empty port which just started blinking orange" as the port numbers are difficult for them to see in these locations.
A similar feature is available in the ethtool package for linux which makes it really easy for identifying ports on servers. It would be great if a similar feature is available on Cisco switches.
Thanks,

Hi Kris,
The Nexus 5K, 7K and MDS platforms allow use of interface beacon mode:
switch(config)# interface ethernet 3/1
switch(config-if)# beacon
The beacon mode allows you to identify a physical port by flashing its link-state LED with a green light. At this stage, the feautre is not available platforms. Hope this helps!

  • Some 2950 switch ports led turn amber even without cable connection

    Hello. Due to a likely NIC problem, after connecting my laptop to a port on the 2950 switch, the led turns amber even after disconnecting the cable.
    2 ports on the switch are having this problems. Ideally the led should be off when nothing is connected.
    Please, how can I correct this problem without restarting the switch because its in a production environment.
    Eddy

    Hello,
    which two switchports are amber? Try toggling the port LED modes by pressing the mode button.
    Have a look at
    http://www.cisco.com/en/US/products/hw/switches/ps628/products_installation_guide_chapter09186a008007e889.html#xtocid41699
    for the different port modes meanings and their respective usage of port LEDs.
    It would also be helpful to see the port status from the switch CLI in case the procedure above didn´t solve the problem.
    Hope this helps

  • Switch port configuration for 3500i AP

    Hi,
    We are due to install a brand new enterprise WLAN based on the WiSM2 platform, 3502i AP and WCS. The APs will be plugged into the 2960S-24TPS-L.
    I have scanned over all documentation and cannot for the life of me find a recommended switch port configuration for connecting the AP to the switch in terms of speed / duplex etc. For example, should I just configure the port to auto detect, or is forcing the speed / duplex the way to go. I could also do with knowing other best practice configurations for AP connectivity.
    Any help would be greatly appreciated.
    Chris.

    The AP comes online with just auto detect, but I want to know if there are any benefits to forcing this to 1Gbps / Full duplex, or even if this is the right way to go. I suspect auto detect is the best method.

  • Tandberg C20 switch port configuration

    Is there a recommended switch port setting (3750x) for connecting a Tandberg C-Series (20,40,60)?
    Smartports?
    Port-Security?
    Access-port only?

    The AP comes online with just auto detect, but I want to know if there are any benefits to forcing this to 1Gbps / Full duplex, or even if this is the right way to go. I suspect auto detect is the best method.

  • ESW 540 24 port switch ports issue

    hello,
    very randomly the ports on the switch stop working and the only way to get them to work again is by resetting the port. we have cisco ip phones connected to the ports and computers connected to the back of the phone.
    what i've notices when the phones or computers stop working is that if i unplug the cable from the switch
    the LED on the bottom right corner of the port will remain Lid. if i check the config the port shows "suspended"
    could you please let me know a better way to resolve this problem, i don't want to reset my switches every day once or twice a day because this is happening so often
    thanks

    That is normal behavior as those ports share switch fabric resources with the GBICs.  When installed the GBIC will have priority and the associated ports (12 & 24) will not be operational.  You seem to have them configured correctly.
    Best Regards,

  • Why would you NOT enable Loop Guard on switch ports?

    Hello
    Why would you NOT enable Loop Guard on switch ports?
    It is disabled by default on all ports.
    Since it prevents loops, in the absence of receiving BPDUs on non-designated ports, why would it not be enabled by default?

    Good luck with that.  FCC already did and have left it alone...  My theory is because... Google charges carriers to use allow devices to use it.  At one point Sprint paid to go exclusive for wallet.  FCC can't force you to buy your competitors product.

  • 2900 XL Switch Port issues

    Hi all
    I have a 2900 XL switch. I tried to connect a computer to a switchport and the port led did not light up.
    1. Can i say that the switchport is faulty?
    2. If i do not plug in any PC to a switchport. Will I get line is administratively up and line protocol is up when i type in the sh int fa0/21 command where fa0/21 is the port that i want to see. ?
    Hope someone can help. Thanks in advance.
    Regards
    Alan

    Hi Alan,
    In case if your port LED is not lighting up when you connect you workstation, it is a strong possibility that the port is in shutdown state. Please go to the interface config and execute the command "no shut" and the port should come up if it is not failed.
    You can also use the command "show port status" to find the status of the ports.
    If the port is shutdown it will show as Administratively down. and if nothing is connected both the line and the protocol will be down.
    Hope this helps.

  • IMac won't power up - diagnostic LED 2 blinks / chirps

    Power light on the front was blinking a quick blip about every 3 seconds and I could hear a very faint, high-pitched 'tweet'. Screen was black, and it would not wake. No hard drive noise, nothing other than the chirp.
    Holding down the power button would not cause a restart, or even a shut down. I unplugged the power cord, let it sit for about two minutes, plugged it back in - nothing. Switched outlets, retried it - nothing.
    Took the back cover off, plugged in the power and saw diagnostic LED 1 on, LED 2 blinking in synch with the chirping.
    Lots of stuff on LED 2 being on, but nothing for it blinking. Any help is appreciated.

    It sounds as if you have a RAM problem. Have you added any lately? Try removing a stick (or two, depending on your iMac model) and switch them around. Make sure they're properly seated as well.
    Let us know how you make out,

  • Phone turns off and led light blinks wont turn back on

    I have the 8100 and have had it for about 2 weeks I bought it off line since my old phone broke. This morning I took it off my charger and went to a meeting after the meeting I looked at my phone and the led light was blinking I hit a button and nothing happened. I then tried to turn the phone back on but nothing happened. I removed the battery waited 5 minutes then put it back in and it started to work again. But again the same thing happened. I tried this multiple times but nothing change it still went back after a few minutes. I took the battery out sim card and memory card out for an hour then put them back in and the same thing happened. Has anyone had this happen before and is there anything I can do for it. Again after I turn my phone on it "shuts off" the led light blinks like I have a message but I ca not do anything the only way to get it out of this is to remove the battery and put it back in but it reverts back to this in a few minutes. Any help would be greatly appreciated thanks

    Greetings, and welcome to the BlackBerry.com Support Forums.
    Leave the device to charge 2-3 hours, and then, still connected to the USB cable, remove the the battery from the device a few seconds and reinsert it. If it boots--leave it to charge to 100% (check Options > Status for the percentage).
    If it doesn't boot--try using a wall outlet charger if you are not. If you are connected via USB to the PC, make certain that you have Desktop Manager (or the USB device drivers) installed, which you can download below.
    Make certain your USB cable is connected to one of the PC's main rear USB ports. Not a USB hub, nor a monitor USB port, nor a USB port on the front of the PC.
    Download Desktop Manager from here:

  • Jabber and Meida Interface Service - Switch port

    Hi All,
    here is from Cisco:
    Before Cisco Jabber for Windows sends audio media or video media, it checks for Cisco Media Services Interface .
    • If the service exists on the computer , Cisco Jabber for Windows provides flow information to Cisco Media Services Interface . The service then signals the network so that routers classify the flow and provide priority to the Cisco Jabber for Windows traffic.
    • If the service does not exist, Cisco Jabber for Windows does not use it and sends audio media and video media as normal.
    My Question is : what does normal means?
    1- we can identify ports for Jabber in CUCM, then create ACL and apply QoS.in that Case what " Normal Traffic " means?
    2- for MSI, do we need to configure anything on the switch port to work peoperly?
    3- How switch knows which Qos to apply based on what MSI saying? still needs an ACL, if yes, what s apoint of using MSI dfor Qos?
    Thanks,
    Hamed

    This would be EF for voice, AF41 for video/voice, and CS3 for SIP signal. Two things typically cause this to get treated as best effort:
    The Windows PC is not allowing the application to set DSCP markings. Group or local security policy can be used to allow this
    The switch is not trusting the data VLAN. Most SRND material suggests using a policer to limit the amount of EF/AF41/CS3 traffic from the data VLAN and to remark the violation traffic to best effort.
    You'll want to start with the MediaNet Deployment Guide. There is a lot going on to make this work.
    The MSI tells the switch what application and ports are being used. The switch then sets the DSCP marking on that traffic.
    Please remember to rate helpful responses and identify helpful or correct answers.

  • Two VLANs on one switch port?

    Currently we have the following
    Cat 4003 with VLAN trunking turned on to multiple switches. Each port in those exterior switches is assigned to a vlan(we have about 60 different vlans).
    What I would like to do is on those exterior switches have two vlans assigned to it.
    We'd like to create a single IP Phone VLAN(let's call it 999) that can span our entire enterprise and would have dhcp deployed on it.
    Each port is connected to an IP phone which has a 2 port switch in them. One port to the wall, one to the pc.
    The switch ports on those phones support vlan tagging
    How would setup an exterior switch to access 2 vlans that connect to 2 port switch on an IP phone?

    To facilitate ease of deployment, use VTP so that you can centrally create the vlans and propagate to each exterior switch. Now I believe you already do have a layer 3 engine or router that does routing between all these vlans. What switches are used on teh exterior ? This is to find out if voice vlan support is available.
    In cat switches, voice vlan is created using command,
    set port auxiliaryvlan vlan
    In IOS based switches,
    int fa0/1
    switchport mode trunk
    switchport trunk encap dot1q
    switchport trunk native vlan
    switchport voice vlan
    switchport priority cos extend 0
    or
    int fa0/1
    switchport mode access
    switchport access vlan
    switchport voice vlan
    I am not sure about support of voice/aux vlan in 4003. We will have check your other switch models/ software versions to determine support for this command.

  • Failed while creating virtual Ethernet switch. Failed to connect Ethernet switch port

    Hello Folks
    I am completely stuck with the configuration of my virtual networks. I have one logical switch left to add to one of my Hyper-V 2012 R2 hosts when I started getting the error below when I try to add logical switches to either Hyper-V Host. I have been using
    the document. 'Hybrid Cloud with NVGRE (Cloud OS)' to implement the virtual networking. Basically using the exact configuration that is in the document. I have added the PA Logical Network and the Network adapters and added the logical switch for it to my
    hyper-v 2012 R2 host and everything was fine. I am now trying to add my ISCSI Logical Switch to the host and this is the error I get. My other Hyper-V host I get this error for any logical switch I am trying to add. Can someone help me with this error. I haven't
    been able to find any information about it.
    Also a some quick info on tracing an error like this so I can figure out what is causing it.
    Thsi is my configuration so far
    So as far as I know everything is peachy untill the error below. Dead stop now
    Error (12700)

    notice your GUID?  you may want to consider ensuring that is the same GUID associated in your database.  Sometimes during data corruption theres a smidge of a chance your sql database kind of either pulls old guids esp if this was reverted to snapshot
    without it being powered off etc.  
    I would try that first.  then i would consider if you get to configure that with your current liscense associated with the host.  I would need way more info to help any further

  • MacBook Pro won't turn on after crash. Magsafe charger LED light blinking rapidly

    Hi. I hope you can help me.
    I have a macbook Pro 13", from september 2012, which crashed earlier today:
    I was charging my iphone through USBport on my macbook (not an Apple USB-iPhone power-cable) .
    My MacBook was charging through the magsafe charger (about 30% power i think).
    I took the phone out to make a call, when that was done, I reconnected the phone to my mac for further charging.
    My MacBook crashed instantly. I took out the USB cable, tried to turn on my mac, but nothing happened. There was no light in the magsafe LED.
    The crashing has happened before, when I've been charging my phone through USB connections, but I've always been able to turn my mac back on.
    This time nothing happened when I pushed the power button. It had comepletely shorted out.
    BTW. Earlier today I received a "storage almost full" warning on my mac, and I was actually in the middle of cleaning that up (deleting downloads and trash files).
    Typical and just my luck!
    Now, a few hours later, I tried restoring SMC (shift+ctrl+alt+power), and now the charger LED is blinking rapidly (but faintly) orange.
    Do you have any ideas on how to fix this? All applestores nearby are closed today, I live in Denmark.
    Thank you so much in advance!
    Kind regards Emilie

    Try the SMC reset again:
    https://support.apple.com/en-us/HT201295
    Then try a NVRAM reset:
    https://support.apple.com/en-us/HT204063
    Then try a safe boot:
    https://support.apple.com/en-us/HT201262
    If no success, then you will have to take it in for service.
    Ciao.

  • How to get Networking Switch Port Configuration (I guess SNMP4j will help)

    Greetings :)
    We have extreme Summit 450e switches installed in our organization. approximately 2000 desktops are connected to these switches.
    Now, I want to make a utility to get info from these switches, for example, which IP, MAC etc is running on a particular switch port. I want to extract these kind of info from all switches and export it into a database.
    Any help, how to start this work.
    Thanks...

    > Any help, how to start this work.
    First research what programmable interfaces it supports.  That includes any management API including SNMP, TCP and HTTP.
    And then from that figure out what you want to do with it.
    After you do both of the above then you start looking to java to program the solution.
