3560 switch config

Having trouble configuring a new switch.Switch B port 48 is connecting to switch A port 37.
Don't know what i have done wrong.
Attached are the running config from both switchs.
Thanks for the help.

My dear let us begin from scratch.
why do you have below settings on switch A on port 37
switchport trunk allowed vlan 1,5,10,25,100
switchport mode access
let us do simple things first.  ( make port setting of switch A prot 37 and switch B port 48 as default ).
and then simply trunk and check.
if all works well, and use vlan allow command on it.
hope this helps.

  • Stopping MAC addresses on 3560 switch interfaces

    Hi,
    I would like to stop certain MAC addresses connecting to the network via a 3560 switch and have configured the config below for VLAN 1. All interfaces belong to VLAN 1. Can anyone tell me if this is the correct config or have I missed something?

    It look like, all the host 'll be reject.
    Try:
    mac access-list extended Bad_Hosts
    deny host 0011.434c.d9bf any 0x806 0x0

  • SRW224G4P uplink to catalyst 3560 switch trunk

    I have many SRW224g4p switchs,and I use a catalyst 3560  for a core switch.
    The SRW224g4p uplink to 3560 switch
    What can I config the port of the 3560 to SRW224g4p(Their are many of vlans in my network)
    and config the port of SRW224g4p to 3560's port
    ps:config trunk port problem

    Hi Wei,
         Are you working on the Linksys SRW224G4P or the replacement Cisco (300 Series) SRW224G4P-K9-NA? Can you attach your 3560 Truk Port Configuration along with the VLAN Configuration?
    Thanks,

  • Physical position of backup Cisco 3560 switch in relation to other produciton switches

    We currently have three 3560 switches connected to each other using SPF interconnect cables. I have a backup switch ready in the event one of the three switches fails. I'd like to keep the backup switch configured and in the rack connected to the three switches. If a switch fails, do the interconnect cables have to be routed in the same way they're currently setup or can they be connected in any order. In other words, if I have the replacement switch in the rack at the bottom with the other three switches and the top switch fails, after loading the config of the top switch onto the replacement switch, can I keep the cables from the second switch connected to the third switch and run the interconnect cables from the failed switch, now switch 1, to the third switch, which is situated in the rack just above the replacement switch? 
    Thanks in advance.

    For 3560s, what SPF ports you use doesn't really matter.
    If the backup will be a cold spare, you may need to worry about port configurations, before you connect it.
    If the backup will be warm spare, again, you can interconnect the SPF ports however you like.  If, though, you create any L2 loops, you need something to break the loop, e.g. STP, FlexLink.
    If you want intentional redundancy, the simplest configuration would be a ring, and assuming the backup is just a warm spare, a root switch defined with the other two non-backup switches connected to it (on the ring).  (The backup would connect to the two non-root switches.)
    Besides a ring topology for redundancy, you might setup a dual star topology, or as you only have four switches, even a full mesh.

  • DHCP and voice vlan on Cisco 3560 switch

    Greetings,
    I'm setting up a Cisco 3560 switch for voice and data comms. I'm looking for documentation with best practice guidelines for the following requirements.
    1. Using the Cisco 3560 as a DHCP server - Config examples.  Do I need to use different subnets for the voice and data vlans?
    2. Layer 2 CoS QoS  - I'm connecting Aastra phones as well as notebooks - I've been told that Aastra also makes use of the voice vlan config through LLDP and that Aastra phones supports CDP.
    Your assistance will be appreciated.

    Hi ,
    Cisco recommends that you have a separate vlan for  voice and data with different ip subnets for voice and data. You will need to configure the dhcp pool accordingly.
    Here is the config guide for setting up IOS DHCP server:
    http://www.cisco.com/en/US/docs/ios/12_0t/12_0t1/feature/guide/Easyip2.html
    Here is the LAN qos recommendations:

  • 3560 switch

    Guys,
    I would like to use a new 3560 switch & i do want it to perform purely as layer 2, also I need to enable spantree per vlan spantree for the vlans besides configuring Qos for the vlans.
    Is there any thing i should do before connect it to my Network?
    How would I apply Qos on the mentioned switch?
    Do I have to configure some thing specific to enable PVST+ ?
    I appreciate ur feedback,
    thanks,

    Hi Friend,
    Cisco switches bydefaut run PVST+ so you need not configure anything to enable PVST+. But 3560 switch PVST+ mode, supports up to 128 spanning-tree instances.
    http://www.cisco.com/univercd/cc/td/doc/product/lan/cat3560/12225se/3560scg/swstp.htm#wp1170819
    To make it pure layer 2 you can ensure "ip routing" is disable at global config mode.It is disbaled by default but you can just double check it.
    To configure QOS you can have a look at this link
    http://www.cisco.com/univercd/cc/td/doc/product/lan/cat3560/12225se/3560scg/swqos.htm

  • How to shut no shut interface of switch using(EEM) Script for 3560 switch

    Dear community experts,
    I'm new for creating scripting for EEM and below is my situation, need your support.
    Present I'm using 3560 switch, one of  the switch port(FA0/1) has added  Cisco Access point(PoE), actually what happening daily this Access point getting struct when I'M doing the switch port (FA0/1) shut  then no shut it is working fine .
    So my question is i need script, that should continuously ping the IP off the Access point if the IP will drop 4 packets the switch do shut  and then no shut for that I need the script, Please help me.
    if it is not possible please provide the batch file, which will ping the particular IP if 4 packet drops it will telnet the switch and go to the interface do shut no shut 
    Note: 
    instead of mentioned 3560, I mentioned 2960 now corrected it  please provide the script.

    This should work:
    ip sla 1
     icmp-echo 10.10.10.1
     frequency 15
    ip sla schedule 1 life forever start now
    ip sla enable reaction-alerts

  • Deploy Office 2010 by using Group Policy - Invalid switch - "/config"

    Hi All,
    We are following steps described in this article -
    http://technet.microsoft.com/en-us/library/ff602181.aspx . However it won't work and will terminate with error code 1 - "Setup ended with error code 1". Further investigations has shown that error is produced by start-up batch script due to Invalid
    switch - "/config". According to the above article to trigger an install we need the following:
    start /wait %DeployServer%\setup.exe /config %ConfigFile%
    However it will fail with the error: Invalid switch - "/config", because obviously "/config" switch does not belong to START command
    It seems to work if we will use the following (without START /WAIT):
    %DeployServer%\setup.exe /config %ConfigFile%
    Could anyone please elaborate on the above?
    Also why would we want to use START /WAIT at all?
    TY

    So, you figured out that this problem occures if path to deployment share, config.xml and setup.exe has spaces in it, that is absolutely true.
    But I see another workaround, not changing your share path to have no spaces in it.
    I suggest changing the setup script.
    Do the following:
    1) Find this part of the script:
    REM If 1 returned, the product was not found. Run setup here.
    :DeployOffice
    start /wait %DeployServer%\setup.exe /config %ConfigFile%
    echo %date% %time% Setup ended with error code %errorlevel%. >> %LogLocation%\%computername%.txt
    2) Use quotes wisely to get something like this:
    REM If 1 returned, the product was not found. Run setup here.
    :DeployOffice
    start /wait "%DeployServer%\setup.exe" /config "%ConfigFile%"
    echo %date% %time% Setup ended with error code %errorlevel%. >> "%LogLocation%\%computername%.txt"
    As you can see, I used quotes to mark those parts of scipt that will have spaces in UNC paths when running the script in cmd.
    It did the trick for me and i have spaces in my UNC path to setup share :) Hope that helps.

  • Embeded Event Manager on cisco 3560 switch

    Can someone help me please? I have EEM configured on cisco 3560 switch. The configuration is below. I want that switch inform me through email when device with particilular IP address become unavailable. For some reason this configuration is not good and I can't tell why. I already try to debug this with debug event manager action mail but didn't see any output .

    The mail part looks good, I'm not sure you are hitting the trigger right.
    Why not do a track on the ip sla instead of the snmp stuff?

  • MAC Addressess not showing on my new 3560 switch

    I have a Cisco 3560 (Switch B) switch I just introduced into my network.  The gigabit ports are trunked from another switch (Switch A) to a Cisco 6509 WS (Main Switch).

    The trunk ports are working just fine.  I have configured all necessary remote management with no issues.  However, my access ports are not working.  I have set them up exactly the same as the adjacent switch A and it works just fine, but the same configuration on the new switch has not been able to pull IP information.  I have provided information as to how the switch access ports are configured on both Switch A (working) and Switch B (not working).  I should note that I tried this with a Cisco 7940 phone and it got stuck on "configuring IP" then I tried it with my laptop and it pulled a 169 IP address.  Both were direct connections into switch B.  When I run a show mac-address-table, neither device shows up in the table.  Only the gig port MACs.  Any thoughts? Please let me know if you need any more information.

    So with this new information, and with my trunk configurations above, what did you mean by a disconnect on the trunk?

  • 1142N NON_CISCO-NO_CDP_RECEIVED with 3560 switch

    I thought the 3560 switches, the 8 port and 24 port are 802.3af standard switches?  When I connect 1142N radios to them I get the no cdp error and the radios are disabled. I have 17 of these that I converted to LAP, and I got the issue both before and after upgrading to LAP from AP.  It's not like I disabled CDP on the switches.

    I may have found the problem. I thought I had initially connected to a switchport that was just setup as a switchport access vlan, with no other configurations on it, and after looking at the port found it was a trunk port, which should work, and does for the other AP's I worked with, but not the 1142N.
    I took one of the other AP's that is connected to the test switch I am using to setup the WLC and AP's and connected that to one of the unconfigured ports, with default settings and the radios both powered up and I saw CDP neighbor detail,
    I removed spanning-tree portfast from the trunk port, and reconnected the AP to that port, I saw it negotiated full power, but I dont see neighbor information. I had to console in and do a no shut on dot11radio 0 for it to come up on all 3 of them.
    I went back and pulled that new one out of the box and reconnected to the interface I used before after removing portfast, still had the same problem, then removed the trunk configuration, and rebooted. Now I see

    Futher puzzlement, plugged that last AP into the test switch which is setup to mimic a remote location with trunk ports for FlexConnect, and after the radio powered up, and joined the controller, saw this.

    Why would radio 0 be admin down? It is enabled on the WLC.  I went into the AP and did a no shut on it too.  Not sure what is going on with this, never ran into this sort of issue before.

  • AAA and 3560 Switch + CNA

    Hi
    Has anyone got this to work?
    CNA. (Cisco Networks Assistants) and AAA (Tacacs+) on a 3560 switch.
    I can’t get the CNA to work in this setup but it works fine on together with 3500XL and 3550 serie switch. With the same parameter.
    this is the aaa conf.
    aaa authentication login default group tacacs+ local
    aaa authentication login no_tacacs enable
    aaa authentication enable default enable group tacacs+ none
    aaa authorization exec default group tacacs+ local
    aaa authorization exec no_tacacs none
    aaa authorization commands 15 default group tacacs+ if-authenticated local
    aaa authorization commands 15 no_tacacs none
    aaa accounting exec default start-stop group tacacs+
    aaa accounting commands 15 default start-stop group tacacs+
    aaa accounting network default start-stop group tacacs+
    ip http server
    ip http authentication aaa

    Hi
    No. I get the prompt for username and password.
    and hit enter. Then nothing happens. It looks like it's trying to build the network but it never get fines. I know it works without the aaa statement. But I can’t live with that.

  • Cisco 3560 switch| mls qos trust dscp question

    Hi everybody
    Hi everybody .
    Please consider the following example:
    3560 sw f1/1--------trunk---SW2
    3560 sw
    f1/1
    mls qos trust dscp
    3560 is using default cos-dscp map, assume a 3560 receives a frame carrying IP packet on f1/1 with COS 4, what will 3560 switch do?
    1) will it use its default cos --dscp map  ( cos 4--.dscp 32) and rewrite 32 in dscp field  of the packet in the frame and provide PHB for dscp 32 ?
    Much appreciated!!
    Have  a great weekend.

    Hi
    No it will not trust the cos value, because You have configured to trust dcsp. So, the switch will trust the dcsp value in the incoming frame.
