Esw-540-48 - direclty connected to port 34, still no MAC in ARP table

Hi all, 
I have a ESW-540-48 with firmware 2.1.21 (latest)
I have the strangest problem: I can 't find the MAC address of a computer plugged directly on the switch in the ARP table.
I'm trying to search by MAC address, and also by port . 
If I reboot the switch, it does work as expected.
Do you think it is software related, and in this case is there anything planned to solve this problem ? 
Or maybe I should just replace my hardware ?
Thanks

Hi Firco, it may be possible it is a smart port issue. The ESW switches are very particular to use the correct smart port roles for the connecting devices. I don't think a hardware replacement is warranted unless the given ports absolutely failed to forward.
As a secondary thought, it could also be a spanning tree issue. Ensure you're using RSTP and/or the host ports have port fast enabled. If using classic spanning tree it takes nearly a minute for a port to go to forwarding state. You can disable spanning tree on the port for testing to quickly rule that out.

  • Help Please! Setting up SNMP on a ESW 540 48 port switch

    Hi There!  This is my first post and I have no idea what I am doing when it comes to SNMP.  We are trying to evaluate our network performance, so we have downloaded a copy of Solarwind’s Orion and installed it on a server.  The topology is as follows.
    A SBS 2003 R2 Server running normal programs.  A second Server 2003 R2( IP 1.2.3.4) running a proprietary program for the business and, hopefully, Orion soon.  The two servers and about 20 XP professional workstations are connected to the esw 540 48 port.  An uplink is attached to a consumer grade Linksys that has 5 workstations attached.  I was told to install SNMP on the workstations behind the Linksys, so I did with the community name = public, Rights = Read Only, and Accept packets from these hosts = localhost and server 1.2.3.4
    I am wondering what configuration I need to do (it is confusing to me) through the cisco web application to set up the switch so that it will communicate with server 1.2.3.4 and the Orion program.  We may switch programs in the future (we are not tied to Orion), but it is what we have to set up the switch with.  I am mainly looking for network throughput information and usage.
    There are just so many options.  Any help would be appreciated….   eric

    Are you trying to use 2 wireless routers in the network?

  • ESW 540 8-port

    Hello forum
    I bought an ESW 540 8-port switch, mainly for the POE capability over all 8 ports, so that we can power some SPA50X phones.
    The concepts of a "managed" switch are challenging for a newbie.
    Is there a way to make this device behave like a boring "unmanaged" switch ??
    We have plenty of bandwidth, and don't need to be troubled by QoS and virtual LAN's, or all the security stuff at this time.
    Making this device work like an unmanaged switch (aka plug-and-pray) would greatly simplify my life.
    TIA's for any tips or clues.

    Good morning
    Hi brian, thanks for using our forum, my name is Johnnatan and I am part of the Small business Support community. As far I know you can´t turn it as “unmanaged” device, however you can use it without any special configuration, these models are such as "plug-and-play" and by default you can connect computers, then setting ip´s to them and have connectivity, however if someday you are curious about how to use it, we can help you with that, by the way here you can see the guide for your device. I apologize for the inconvenience, however I hope you find this answer useful,

  • ESW-540-24 suspended port/s

    HI all,
    I have a customer with a ESW-540-24 running the versions shown below.
    Software Version
    2.1.21
    Boot Version
    1.0.0.04
    The snag I have is that whenever I connect an AP via the power injector, it suspends the port. Using a laptop it's fine connecting straight into the switch.
    Hardware is:
    SB-PWR-INJ1
    WAP321-E-K9
    When I go to port settings > edit in the GUI, it shows the port as suspended and despite checking the box to reactivate the port, it still shows as suspended. I've disconnected the AP and tried the reactivation again but still no joy.
    I've been through the management GUI and looked at all the security related stuff and there is nothing I can see that will cause this - must have missed something though - can anyone shed any light please?
    Many Thanks
    Alastair

    Hi Tom,
    Thanks for the reply.
    Yeah tried that too but when you first log in to the switch and click Smartport Wizard, the new window opens OK but does not allow me to select a port
    I tried hovering over the port on the switch image that appears, selecting it, then selecting the Access Point profile from the dropdown, them it whinges words to the effect of "You must select a port to apply the profile to"
    I thought that might be a bug in the software so upgraded to 2.1.21 but the same thing happens.

  • ESW 540 Combo Ports

    Hello,
    I am interesting what Combo ports mean in ESW 540 which has 4 SFP? Can I use 4 optic SFP at the same time(or 1000BaseT SFP) ??

    Hi Kristijan,
    Just out of interest, are you using firmware version 2.1.19 on the switch, your switch may be using an older version of the firmware ? 
    But there should be no reason why the switch interfaces 11,12,23,24 could not be placed in access mode, seems a bit weird.
    I believe, if you check the VLAN interfaces, vlan1 should still be untagged on those "trunked" ports.
    So, please check the firmware version, but the ESW is covered by a great Warranty, so if you are still having issues, call the Small Business Support Center (SBSC) and allow them to share your screen via webex and resolve your configuration issue one way or the other.

  • VLAN ESW-540

    Hi,
    I have a new switch ESW-540 24-port, I upgrade firmware to 2.1.19.
    I build 2 VLAN for 2 networks: VLAN 2 and VLAN 3 . I don't use the default VLAN 1.
    This is my configuration:
    port e1 and e2 : ACCESS PORT on UNTTAGGED VLAN 2
    port e3 and e4 : ACCESS PORT on UNTTAGGED VLAN 3
    port e1,e2,e3,e4: EXCLUDED VLAN 1
    port e24: TRUNK PORT with UNTAGGED VLAN 1 and TAGGED VLAN 2 and VLAN 3
    Communication (ping) between e1 and e2 --> OK
    Communication (ping) between e3 and e4 --> OK
    Communication (ping) between e1,e2 and e24 --> NOK  :-(
    Communication (ping) between e3,e4 and e24 --> NOK  :-(
    Communication (ping) between e5,e6,e7,.... (VLAN1) and e24 --> OK
    Communication (ping) between e5,e6,e7,.... (VLAN1) and VLAN2, VLAN3 --> NOK - It's correct.
    Any special configuration on e24 trunk port ????
    Can you help me ???
    Thanks,

    Hi Albert,
    Bit concerned about your testing process.  You have proved that untagged switch ports in vlan 1 can communicate with e24.  that makes perfect sense.
    What what are you using (connected on e24 )  to check for tagged packets egressing out of E24 from PCs connected on  vlan 2 and vlan 3.  This testing device you are using must be vlan aware.
    The switch port 24 must be connected to a VLAN aware router or layer 3 switch  that is trunked for ;
    vlan1 untagged
    vlan2 and vlan3 tagged.
    So that routing can occur between vlans.
    regards Dave

  • How do I get the IP address off my 3 esw 540's they are already bolted up and mounted?

    New IT Manager, prior IT staff did not document anything I have identified all routers and switches so far except the 3 ESW 540's throughout the building the issue is they are already bolted up in place and in use I cannot find a console port and need the ip addresses to add them to my Configuration Professional Community.

    Hello,
    There are a few ways we may be able to locate the IP for those switches.
    The easiest option would be to download and install Cisco FindIT, that does work with the ESWs, assuming Bonjour hasn't been disabled on them.
    That however only seems to work if you are in the same subnet as the management IP of the switch, I tested it a bit here in my lab.
    You can also try getting into another Cisco device that is connected to those ESWs and try looking at the CDP neighbors, although I am not sure this would show you the management IP address (it does not on SG200s, although I do remember seeing that before on some Catalysts)
    Another option would be to use some sort of IP scanner, but again that depends on you being in the correct VLAN when you run the scan.  You may also need to know the MAC address of the switch to make this useful. 
    One other thing to note is that the ESWs do not support CCP.  They use a similar but different program called CCA (Cisco Configuration Assistant).  This may also be able to discover the device for you, but one again you would probably need to be in the management VLAN.
    Having said all of that, your best bet may be to just get a console cable in there somehow.  It is on the back of the switch, on the opposite side from the power cable.  It is not a console port like on the enterprise switches, but rather a standard serial port. Of course, you will still need to know the username and password to get into them, so you may end up having to reset the switch to factory defaults regardless.
    Hope that helps, and good luck getting into them,

  • ESW 540 and Ether Channels

    We are trying to configure Ether Channels on our ESW 540 switches. We have configured the port(s) and made the physical connections but the Ether channel is only showing up at 1000M. It is my understanding that the port should be displaying at 2000M if configed with one pair of ports. Are there any other settings that need to be completed?
    Thank you,

  • New UC560 and 3 ESW-540-24P Switches, best way to wire them

    We are installing a UC560 and 3 ESW-540-24P switches at a client in a couple of weeks.  I have installed many of these but have never installed one with multiple switches.  What is the best way to connect these together physically.  They will be all in the same rack.  Was just wondering the best way to "series" the switches together and what ports to plug them into.  Any suggestions would be appreciated.

    There is a Smart Design: Implementation Guide at :http://www.cisco.com/web/partners/sell/smb/tools_and_resources/smart_business_comm_system.html
    Implementation Guide
    Smart Business  Communications System 2.0 – Implementation Guide
    The implementation guide complements the SBCS 2.0 Design Guide through  the detailed guidance for SBCS 2.0 based Main Office deployment. This  document leverages the GUI configuration capability with easy-to-follow  step-by-step network deployment guidance using CCA v2.2. It also  includes an installation checklist to assist during the installation  process. It is recommended that users refer to the SBCS 2.0 Design Guide  for underlying design guidance and considerations.
    In this (figure 6) it shows a 48 and a 24 port switch connecting to each of the UC560 expansion ports (there are 2 GE ports for expansion on the 560).
    These could also be 2 48 port switches (96 total ports).  (In your scenario, I would connect 2 this way and the third to one of  those 2.)

  • VLAN Tagging ESW-540 and 3750g

    Hi everyone!
    I'm a self taught cisco type person who really specialises in ASA rather than routers, but have fumbled my way through many a task with the help of this site and google... However!  I am currently tasked with setting up a network, pretty much from scratch, that requires some fairly hefty VLAN deployment.
    My hardware on hand (already existed so can't can't change anything easily) 5x ESW-540-48 Switches, 1x3750g switch, 1x2811 router. 
    I don't believe the router should be required as the 3750 is capable of intervlan routing.  So what i'm trying to achieve is as follows:
    VLAN 1 - 172.16.8.0/22 (A)
    VLAN 2 - 10.0.2.0/24     (B)
    VLAN 3 - 10.0.3.0/24     (C)
    VLAN 4 - 10.0.4.0/24     (D)
    VLAN 5 - 10.0.5.0/24     (E)
    VLAN 6 - 10.0.6.0/24     (F)
    VLAN 7 - 10.0.7.0/24     (G)
    VLAN 8 - 10.0.8.0/24     (H)
    VLAN 9 - 10.0.9.0/24     (I)
    Server Room - Servers connected to the 3750G
    3750G connected to 5 ESW switches distributed around the building.
    ESW-1 Will have VLAN(A) and VLAN(B) devices connected, specified at port level.
    ESW-2 Will have VLAN(A) and (C) devices connected, specified at port level.
    ESW-3 Will have VLAN(A), (D), (E) and (F) devices connected, specified at port level.
    ESW-4 Will have VLAN(A), (G) devices connected specified at port level.
    ESW-5 Will have VLAN(A), (H) and (I) devices connected, specified at port level.
    Now at one point I actually had the VLAN's *working* in that I could specify an IP address and could ping to and from it!  However DHCP wasn't passing despite numerous attempts with DHCP relay and IP-Helper configurations.
    Also I was having issues with VLAN 1 as the native VLAN, the ESW switches don't allow you to do much with them, as they 'weren't created by the user'.  So tried switching that out to VLAN11 also but with very little success there (I had to change the native vlan on all trunks to VLAN 11)
    All the 10.x.x.x addresses need to be able to communicate with each other
    All the ESW switches need to be able to handle their respective VLAN's as well as VLAN 1 (for Printers and wireless access points distributed around the building).
    Partly i'm doing this in the hope that maybe some helpful soul can make some sense of it, but also just the fact of writing it down MAY firm it up in my head somewhat
    Thanks in advance!
    Simon

    Ok so - i gave up at 2am this morning, and going back to it with a fresh head!  Here's the situation as it has unfolded...
    I have configured up 4 of my vlans for the purpose of testing, so you'll note there are a few missing.
    I have moved the Native to VLAN 11 because the ESW's were doing  something weird, and wouldn't allow me to do anything with trunking...  If anyone can see a MUCH easier way of doing this, please feel free to  chime in!
    Primarily my question though is - why isn't  DHCP working?  Do I need to configure DHCP relaying on the ESW  switches?  Or should the DHCP REQ be passed across the entire vlan back  to the 3750 regardless.  And if I do need to configure relaying on the  ESW - how?
    In my server room I have a 3750 and a bunch of servers. 
    One of these servers - 172.17.10.229 is a win 2k3 dhcp server (physical not virtualised)
    On my dhcp server I have configured scopes for each vlan (not superscoped)
    My servers are sitting on the first 16 ports of said 3750.  I have set their ports to native vlan 11 and allow vlans 1-3 and 11.
    My ESW switches are on ports 46, 47 and 48.  Likewise, their native has been moved to vlan11 and allowed vlans 1-3 and 11.
    My ESW switches have been moved to native vlan11 and trunked each of their port 48's to allow all vlans.
    Test 1:  Unmodified port #10 on ESW1 (default vlan 11). 
    Connect DHCP device. 
    IP address assigned from vlan 11: 172.17.10.101. 
    Can ping all VLAN interface addresses.
    Test 2: Modified port #11 on ESW1 (VLAN 2). 
    Connect DHCP device.
    No IP address assigned. 
    Set static IP address 10.0.2.55/24. 
    Can ping all VLAN interfaces, DHCP server, entire network. 
    Change IP address of test device to 172.17.10.102 for testing.
    No ICMP responses from anywhere - this is good!
    So as you can see i've done my homework - well most of it obviously.  Because it still isn't working
    Here's  the config of the 3750, the ESWs of course are a bit harder to just  post my config, but the general state is something like this...
    ESW Switch 1
    Native VLAN 11
    IP Address:     172.17.8.101 255.255.252.0
    Default Gateway:     172.17.8.253
    Port 48 802.1q trunk - allowed VLAN's 1-3 (tagged), 11 (untagged)
    ESW Switch 2
    Native VLAN 11
    IP Address:     172.17.8.102 255.255.252.0
    Default Gateway:     172.17.8.253
    Port 48 802.1q trunk - allowed VLAN's 1-3 (tagged), 11 (untagged)
    ESW Switch 3
    Native VLAN 11
    IP Address:     172.17.8.103 255.255.252.0

  • ESW 540 switch issue

    Hello,
    I have a ESW 540 48 port gigiabit switch.  We have had it a year and a half.  In the past year it has experienced this cycle of problems:
    After a reset, within a week the fans are on full blast. Within less than a month the webgui is gone - not accessable. the switch will still switch, but to do anything to it means it has to be reset completely.
    I cannot figure out how to call Cisco support for this, it has a 5 yr warranty which we are well within. I am ok with the hardware replacement but cannot figure out how to arraign that.  the Support for cisco is not they type of support structure i am used to, in some cases it talks about contracts but then I cannot find prices or even how it works.
    any advice? am i just looking in the wrong places for support or does cisco operate on a diffent model than other tech companies (like Apple or HP) i just am wondering if i should adjust my expectations to less?
    yes i am a bit frustrated, i went out on a limb with going to Cisco for the 'best' and our other switch a 520 is also having problems  
    our old netgear switches worked great for about 5 years until i felt we need to improve them.
    please help a clueless IT guy out

  • ESW-540-24

    Dear Support Team,
    What is the max power consumption of switches
    ESW-540-24
    Br,
    Lukasz

    As of 22-Mar-2010, the ESW 500 series data-sheet and lack of a power-calculator still fails to meet the needs of installers who need to consider the power-draw and heat dissipation of the switches from the perspective of UPS and heat management.
    The main shortcoming is that under the "Power" section, it just says "24- and 48-port models: 100-240V 47-63 Hz, internal, universal;"  This information isn't much use for even the simplest of calculations.  More usefully, it would provide a Volt-Amp (VA) rating.  One could then apply a rough-and-ready power-factor (60% according to UPS vendors), to get W = 0.6 * x VA for power needs, and W = 0.6 * (input VA - PoE VA) for heat needs (since the PoE wattage is mostly dissipated away from the swtich).
    Happily, this thread provides the kind of raw information which the Cisco 'classic' power calculator is probably built from.  But it's still a real hassle that I had to go Googling for it instead of finding even the basics on the data-sheet, where it belongs.

  • New ESW-540 switch with cold start problems

    Hi
    A customer of mine is having serious problems with several ESW-500 switches.
    He started a discussion under Netpro, but haven't received any answers. This might be the right group?
    He wrote:
    I have two new esw-540 switches (one 48 port  and one 8 port),
    which are making unauthorized cold starts and  that gives me a lot problems.
    (now it is about three switches)
    I added:

    Hello!
    My name is Robert and I am network engineer for the Cisco SBSC. This is the correct place for the ESW500 series.
    From the error messages you are seeing, I would recommend to disable the Bonjour service to see if that helps with the reboots. I am currently looking into the error messages you are getting to see if there is a solution. I would recommend giving us a call as well for immediate assistance on the error messages. Below is a link for our support center numbers.

  • ESW 540 24 10/100/1000 POE Firmware upgrade

    It seams a new firmware was issued on the cisco download site on january 11 :
    ESW_540_K9_2.1.16.zip
    I have succesfully downloaded this file, but each time I try to unzip it, I get an error.
    I have tried to download it several times, using different navigator and different pcs or macs and using the donwload manager or without it, and I get the same result.
    Also the md5sum of the downloaded file is the one indicated on the download screen :
    Cisco ESW 540 24-Port 10/100/1000 PoE Switch-Release: 2.1.16
    Image name: ESW_540_K9_2.1.16.zip
    Details
    Release
    2.1.16
    Filename
    ESW_540_K9_2.1.16.zip
    Release Date
    11/Jan/2010
    Description
    Firmware for ESW540 Series Pro Switch
    Size

    Router Checksum
    0x1b15
    MD5
    4ba13dac6df27316c7cecb670c42c6e4
    So the conclusion is that this archive is corrupted.
    As this product is for the SMB market, I am unable to open a case on the Cisco site to ask for a working version.
    Who is responsible for this and how to get a good version ?
    Regards,
    Alain RICHARD

    I jumped into the middle of this and have some information to share.
    Firmware release Notes:
    http://www.cisco.com/en/US/docs/switches/lan/csbms/esw500/release_notes/Release_Note_2.1.16.pdf
    states about the first table... (refer to the table):
    In the table above the boot version is different for the 8 port models versus the 24 and 48 port models.
    Software version 2.1.16 requires boot version 1.0.0.7 for the two 8 port models
    esw520-8p-k9-2116.ros for ESW-520-8P
    esw540-8p-k9-2116.ros for ESW-540-8P
    The remaining 24 and 48 port models require boot version 1.0.0.4. if the switch does not have the boot version released in May 2008.
    These are esw520-k9-2116.ros for
    ESW-520-24P
    ESW-520-24
    ESW-520-48P
    ESW-520-48
    and esw540-8p-k9-2116.ros for
    ESW-540-24P
    ESW-540-24
    ESW-540-48
    http://www.cisco.com/cisco/web/solutions/small_business/products/routers_switches/esw_500/index.html-tab-Resources
    - Pages 41-45 of the Admin Guide show how to upgrade the  firmware.
    - Pages 374 - 376 describe the options on the Software  Upgrade page.
    File Type = Software Image for .ros  files
    File Type = Boot Code for .rfb  files
    Basic Outline:
    1.  Upgrade Boot Code (PC --> ESW)
    2.  Upgrade Software Image (PC -->  ESW)
    3.  Change Active Image
    4.  Save Configuration
    5.  Reboot
    The Getting Started section of the Admin Guide should have  text on how to upgrade the Boot Code.
    Software Download should have both the boot code and the Image file listed separetly now:
    A Final note:  CCA does not support boot code upgrade on the ESW switches, only Firmware.

  • Database account locked as it tries to connect different ports for 16 times

    I need a help in answering one of the issue encountered last week.
    I have created a database link and tried to access the information from a table using the program written in another language. The password provided was incorrect for that user while creating database link. So we expected that,while retrieving the data, Database connection has to be errored out as password provided is incorrrect.
    But unfortunately, user account was locked out. When i checked with DBAs they mentioned that it tries to connect 16 ports with in a min of time.we were shocked as it STOPS another scheduled jobs with that user. and affects production badly.
    As per the program, it has to connect only one time and yesterday we tried to execute the program in DBAs observation and it errored out as expected. Didn't tried for multiple ports.
    Now the question is, WHY the database connection established 16 times last week and caused user account locked. DBAs are unable to answer it. Any EXPERTs opinion on this would greatly appreciated.
    I have verified managing ports in oracle documentation, it was mentioned that if one port is busy it will try to connect to another port in the range of ports mentioned during the installtion. DBAs verified ports related file and it was blank. and they are not agreeing with this reason. Please HELP me in finding the correct REASON for this.
    is it a NETWORK issue or issue with DATABASE SERVER only?
    Thanks
