Etherchannel and STP on HP Blade Switches

Hi Guys,
I have a 6509 with and etherchannel connection to an HP Blade switch... the channel is made up of two phy ports between the two switches...
When I try ti bring up the link, the 6509 ports go into err-disable and i get the message below.
I have done all (I think?) checks that there is to ensure etherchannle compatibility and STP stuff but still no luck...
can anyone suggest soemthing I do ro check that might shed light on this...
thanks

Hi ankur,
thanks for your response. currently the etherchannel operatiosn mode on the 6509 is set to manual, which is the case globally for the 6509 and we have 50 pairs of this blade switch running on this 6509... I don't think that that is the cuase of this issue since this is the only one not forming the channel and goes into err-disable...
the blades also have similar configs in them...
the only thing I see different on ports 10/24-25 is that it has bpdu-guard set to disable while the rest are set to default... could this make a diffrence?
also, does the order of enabling the cisco end and the HP blade end make a difference? i.e. should I bring up one first than the other?
the thing is I cannot "experiment" fully as this is a full prod network...
Any input si appreciated...

  • VTP and STP on SG300-28 Switch

    Hello everyone,
    I have a question, does the SG300-28 support VTP and STP?. I want to add it to my network's VTP domain so I don't have to manage vlans manually on the SG300-28 and also be able to configure STP to keep my network loop free.
    Thanks.

    VTP = no.  You must manually create and manage all of your VLANs.  However, you should look into GVRP, which is a VTP replacement.
    STP = Yes, but there are different STPs.  The SF 300 supports 802.1d "old" SPT, .w "RSTP", and "MST".
    You should look up the specifications.
    If you are using any variety of PVST, you may have issues.  Beware.

  • Etherchannel and STP ?

    Looking for a bit of tech advice..
    Each of my floors connect back to the core via a single uplink (fiber). Floor switches are 3560's. Floors 5,6 and 7 and the most important b/c
    of the call center / services we provide.
    I would like to use redundant links for each of these floors back to the core using etherchannels on both sides of the trunk.
    Etherchannel will be LACP - active active on both sides.
    On the core side, I will spread the etherchannel (LACP) across line cards and on each 3560 there will be an EC between Gi0/49 and Gi 0/50.
    I have tested this in the lab and it works fine..but
    With STP turned on for the 3 vlans in the trunk, the re-converge time is to slow once one of the ports in the EC goes down and comes back up.
    If I kill STP for the 3 vlans, then there is no relearn time when the physical port comes back up in the EC.
    Given the fact that my EC config is correct, do I really need STP in this scenario ?
    Advice would be appreciated.
    Cheers
    Dave

    Well I would always run spanning tree protocol, no matter what. It's just not a good idea to do otherwise. Even if you don't have any "physical loops" in your network, you should always run it.
    You could always run L3
    But if I remember correct, on an Etherchannel, spanning tree BPDUs will follow one port within an etherchannel, but I'm not 100% correct about how that part works.

  • SW_MATM-4-MACFLAP_NOTIF: and 3120 Blade Switch

    We had two 3120 blade switches fail on us in our production environment and when we plugged in the RMA replacements, it caused a loop that took down our VM environment:

    Has anyone else experienced this?  In Vsphere the Nics are set up for 'IP hash' and the the OS team claims nothing has changed in their configuration.  We have our blade switches plugged in to an older HP C7000 chassis that has had a number of blade failures of late;  both server and switch.  I'm suspecting this is a chassis issue.  
    Thanks!
    -anne

    Are you able to supply some additional information as to how things are connected. For example:
    - Confirm it is the VMware ESX hosts in the blade chassis that are configured with IP hash?
         *yes they are configured with IP hash except for 2 nics which they have x'd out...meaning they are disabled.
    - Are the Catalyst 3120 switches configured as a Virtual Blade Switch?
         *I don't know, how would I know that?
    - The connectivity from the blade switches to the external network and the configuration of that network
         *Each switch stack has 2 10Gig uplinks to Nexus 5K's that were not involved in the mac-flapping.       The loop was between the VM's...
    Also, the two switches that were replaced:
    - Were these both part of the same chassis?
         *They were on separate chassis.
    - What was the process to replace them e.g., plugged in, all external cables connected and then configured?
         *There were no external cables on these switches except for the stacking cables...no uplinks.

  • Nexus5k - LACP towards HP blades switch(and nortel blade switch)

    Hi
    First I have to say this is not the first time i'm working with these old switches and not the first time i've configured LACP on them.
    So I did the config on the blade switch , enabled LACP, the uplink ports as members and tagged.
    Created port-channel on the nexus side.
    when i try to bring up the ports on the Cisco Nexus 5k this is the errors I get. this is fot the HP blade:

    I had one port-channel for a switch that came up with no problems. I compared the config but could not identify the issue.the config is very similar.
    has anyone encountered these errors or similar before? if yes, what am I missing? and also what does it mean when it says "

    Thanks,
    Mary

    Marcel,
    Thank you for your reply.
    I tried again right now with the command you suggested but still no luck.
    we have so many more hp switches with the similar config that are working fine. I just can't figure out why these 3 switches are having issues.
    my current config on the member port is as below

    set trunk 5/40 auto isl 1-1005,1025-4094
    On the Blade Switch 3020 I have done :
    interface GigabitEthernet0/17
    switchport trunk encapsulation isl
    switchport mode trunk
    shutdown
    channel-group 1 mode on

    Will that work ?
    Could you tell me if I have to put the trunk port on the same VLAN ?
    Many thanks in advance for your help.

  • Two forwarding root ports on cisco 3120 blade switch.

    Hi,
    <br />
    <br />After upgrading blade switch 3120 to 12.2(46)SE, I could see two root ports in which both are forwarding.
    <br />
    <br />Te1/0/1 Root FWD 2000 128.27 P2p
    <br />Te2/0/1 Root FWD 2000 128.81 P2p
    <br />
    <br />Where as STP should've kept the other root port as blocked state and named it has Alternate port.
    <br />Also started seeing Mac flap messages.
    <br />As soon as IOS was downgraded to 12.2(40)EX3, Problem was solved, even messages were stoped.
    <br />Seems to be bug, but couldn't get any.
    <br />

    Hi Rob,
    I have faced this issue with many enclosures so far and the only option left here is, you need to reboot the enclosure.
    This is an issue with the IOS code and you have to open a case with HP to get the appropriate IOS ver. Probably 15.0 code has this issue resolved and I haven't seen this issue further after the Upgrade.
    Thanks,
    Sagar

  • EtherChannel Bundle for an HP Blade server

    I'm running a Catalyst 6513 switch with Native IOS installed. I have created a EtherChannel bundle for an HP Blade server running with two clustered (teamed) NICs. The configurations are as follows:
    interface Port-channel100
    no ip address
    switchport
    switchport trunk encapsulation dot1q
    switchport trunk allowed vlan 2
    switchport mode trunk
    end

    switchport
    switchport trunk allowed vlan 2
    switchport mode trunk
    channel-protocol lacp
    channel-group 100 mode active
    end
    The problem is that running the interfaces at 1GiG causes the two NICs to insert and de-insert on the network every second but forcing them to 100 Meg makes them perform normally. These are connected using Cat5e cables which are 1GIG certified. What could be the cause for this problem?

    As per your mention, I think the problem is with the server on the other side. The speed is not compatible on the other. Why don't you set the speed/duplex to auto and check it out?.

  • EtherChannel and LAN Design for new buildiing(s)

    What is the recommended best practice for EtherChannel size for a 3750G-12S stack? Will I benefit from stacking these with the StackWise cable on the backplane, or would it be better to run these independently back to the 4006 with individual EtheChannels?
    The 3750G-12S stack will likely be 1 or 2 devices at distribution layer for upwards of 18 - 20 2960G-48 access layer switches and approximately 20 1242LAP AP's in addition to max capacity of end users attached to the switches.
    I am considering implementing a 4 gig EtherChannel between the 3750's to the 4006 for this load. My limit is the number of available ports on the 4006 and obviously the max load of links on the EtherChannel.

    Unsure there's a single "best practice" for stacking or not. Some advantages/disadvantages to both. Part of the decision might rest on whether the 3750s will be L2 or L3.
    Stackwise could be a performance bottleneck if you believe there would be much traffic between switch ports, but if most will transit your 4006, your links to it would be the bottleneck.
    What you might consider, a single 3750G-12S (four?) that can handle 2 links from each access switch, that are Etherchanneled and not connected to the same 3750 stack member. This with the 4 gig Etherchannel to the 4006, which again should be spread across stack members.

  • MDS FC Blade Switch for IBM - Licensing

    Hi,
    our customer has got installed the 20-port-switch of the "Cisco MDS Fibre Channel Blade Switch for IBM BladeCenter". He wants to change some of the links now. For that reason he asked me:
    - Is there a fix relationship between a port and a license?
    - Can we use any port as long as we fall below the number of licenses?
    Thanks in advance and regards
    Matthias

    Hello Matthias,
    Cisco Fabric Switch for IBM BladeCenter (20 ports; 14 internal 2/4 Gbps, and 6 external full-rate ports) licenses for internal ports are allocated as the ports come up. Licenses for external ports are allocated sequentially.
    Refer "On-Demand Port Licensing" section on CLI guide here :
    http://www.cisco.com/en/US/docs/storage/san_switches/mds9000/sw/rel_3_x/configuration/guides/cli_3_3/ondport.html
    Customer can select the specific external ports he wants licensed.

  • Cisco Blade Switch

    I am having problems with configuring speed on uplink ports on cisco blade switches (Cisco Gigabit Ethernet Switch Module for HP BladeSystem p-Class). I can configure fixed speed on uplink ports (Gi0/19-22) but after reload I am getting message that this command was rejected:
    speed 1000
    ^
    % Invalid input detected at '^' marker.
    and then auto-1000 speed is specified.I need fixed speeds on those ports.What is strange that access ports (Gi0/1-18) dont have this problems.I excluded firmare problem,vlan,vtp negotation. The problem is still recouring even if I configure this ports only with speed comand and nothing more. Could someone give me some clues? Thanks

    Checked that olso,ports are 10/100/1000/auto Base-TX with half/full/auto duplex, so it seems that it is not an issue. I am getting this problem after this communicate:

  • CSM in Bridge mode and STP

    How CSM deals with the situation when both modules become active? How can I configure CSM to passthrough STP BPDUs to break loops? I know how can I do it on FWSMs but wondering if there is a way to do it on CSM or there is no way to avoid loops when FT vlan is dead.

    There is no way to let BPDU go through and there is no way to avoid loop if the FT vlan goes down.
    You have to make sure it never goes down by using etherchannel and any other possible solution.

  • Catalyst Blade Switches 3020 For HP Blade Chassis

    I was trying to access Catalyst Blade Switch 3020 through serial port to reset the lost password. This Switch is plug-in to HP c7000 Chassis. I followed the instruction from Cisco documentation for this password re-set process as follows.
    { Step 1 Connect a terminal or PC with terminal-emulation software to the switch console port.
    Step 2 Set the line speed on the emulation software to 9600 baud.
    Step 3 Push the release latch on the front of the switch to the open position.
    Step 4 Pull the switch partially out of the module bay until the power disconnects, and then push it in again. The switch restarts when it reseats in the server chassis. The switch performs POST after power is applied.
    Step 5 Push the release latch on the front of the switch to the closed position.
    Step 6 Within 15 seconds, press the Mode button while the System LED is still flashing green. Continue pressing the Mode button until the System LED turns briefly amber and then solid green; then release the Mode button.
    ------- Step 6 did not work. System LED neither flashing nor in Solid state. I can not connect through Serial port any more! Any help.....

    Here in the "blade switch for HP" a request processing application is running in a server. when we use the same type server stand alone with a separate switch it processes 80,000 requests per 4 hours. But when this blade server in the blade switch it only processes near 6,000 requests per 4 hours.
    That what I mean like "Network delay"...
    That is what I cannot understand.
    I have attached the current configuration of the blade switch so you can go through it.
    Is there any best practices specific to that type of blade switch that should enable?
    Thanks for your help
    regards

  • MIBS to Monitor Etherchannel and trunks via SNMP

    I would like to monitor the status of etherchannel and trunk configurations in 6500 Catalyst switches running both CATOS and IOS. I would like to understand the specific mibs/OIDS that should be monitored for etherchannels and trunks. I am trying to get a better handle on tracking the etherchannels and trunk dynamically and then understanding when the ports are having issues (up/down and errors). I need to understand how to differentiate these type of ports from regular access ports.
    Thanks,
    Tim

    Hi Tim,
    what exactly do you want to query via SNMP?
    For an (PAgP) Etherchannel, the member-interfaces might be interesting:
    https://supportforums.cisco.com/message/3957914#3957914
    For a trunk, you could start with the operational mode, depending on the platform you can use:
    vlanTrunkPortDynamicStatus (CISCO-VTP-MIB):
    vlanTrunkPortDynamicStatus.49 = notTrunking
    vlanTrunkPortDynamicStatus.50 = trunking
    vlanPortIslOperStatus (CISCO-STACK-MIB):
    vlanPortIslOperStatus.13.43 = notTrunking
    vlanPortIslOperStatus.13.44 = trunking
    Hope that helps
