Etherchannel two cisco 3750 stacks for iscsi?

I have two sites connected by 96 strands of fibre. At each site I have an IBMv7000 relicating to the other one. For iSCSI traffic I have two Cisco 3750 switches, each are in 2 switch stack. 
SAN A                         Fibre Link                          SAN B
        |                                                                        |
Cisco Stack A =========================Cisco Stack B
        |                                                                        |
        |                                                                        |
iSCSI Clients                                                       iSCSI Clients
My question: Is it ok to connect the the two stacks with etherchannel using the fibre links? Will is provide the necessary redundancy, if one of the interfaces goes down?

What model numbers of 3750 are you using?
What is the distance between the stacks as this will dictate your fiber run modules.

  • Etherchannel issue between 3750 stack and WS-CBS3012 for IBM blade centre

    Hi,
    We are trying to configure Etherchannel between four ports of cisco 3750 stack(2ports from one switch of stack and two ports from another switch of same stack). We are facing issues with this setup. The ports in WS-CBS3012 are going to err disable mode.
    Is  there any limitations associated with such a cross-stack etherchannel configuration. Please suggest if there is any particular sequence of configuration involved.
    Switch1 in stack
    int gi 3/0/3
    switchport mo trunk
    switchport trunk allowed vlan 10-30
    sw tr en dot1q
    channel-group 1 mode on
    spanning-tree guard root
    switch 2 in stack

    in WS-CBS3012 ports are configured with trunk,allowed vlan and etherchannel configuration with mode on.

    Hi,
    The commnad "no spanning-tree etherchannel guard misconfig" on WS-CBS3012 resolved the issue.

  • MAC address flapping on 2 x Cisco 3750 (Stacked)

    Hi All,
    I am having some issue with my connectivity.
    The setup with HP virtual connect (VC) is as below:
    Server A NIC 1 -- VC 1 -- Switch A
                 NIC 2 -- VC 2 -- Switch A
    Server B NIC 1 -- VC 1 -- Switch A
                 NIC 2 -- VC 2 -- Switch A
    The VLAN configuration are done on individual NIC card on the servers and the switchport on Switch A facing the VC connect are all on trunk mode.
    Currently I am seeing MAC address flapping on my Switch. The switches are CISCO 3750 and are being stacked so it appears logically as 1 switch.
    Any idea what might be the problem?
    Below is an output of the flapping on the switch.
    %SW_MATM-4-MACFLAP_NOTIF: Host xxxx.xxxx.0637 in vlan 1 is flapping between port Gi2/0/3 and port Gi2/0/5
    %SW_MATM-4-MACFLAP_NOTIF: Host xxxx.xxxx.46eb in vlan 1 is flapping between port Gi1/0/5 and port Gi1/0/7
    %SW_MATM-4-MACFLAP_NOTIF: Host xxxx.xxxx.661d  in vlan 1 is flapping between port Gi2/0/15 and port Gi2/0/7

    Hi,
    Problem of MAC FLAP could resolve by following methods:.
    Check with the server providers to see if the OS and server platform support 'NIC' Teaming (NIC Bonding).
    FYI - NIC teaming allows users to group two or more physical NICs into a single logical network device called a bond. Once a logical NIC is configured, the virtual machine is not aware of the underlying physical NICs. Packets sent to the logical NIC are dispatched to one of the physical NICs in the bond and packets arriving at any of the physical NICs are automatically directed to the appropriate logical NIC. If one of the underlying physical NICs is broken or its cable has been unplugged, server will detect the fault condition and automatically move traffic to another NIC in the bond.
    Hope that help

    if yes then just make sure of the cable which should be Single mode.
    if still not working try to reverse the cable connectors on one side as well.

  • Serial numbers on 3750 stacks

    CW Contracts reporting reports the master SN. How can I pull all the SN for all devices in a 3750 stack for asset/inventory purposes?

    You need to create a Custom Report Template in RME Reports.
    - Association : don't pick anything
    - Inventory Group : Chassis
    - Attribute : Chassis Serial Number
    - Operator : Contains
    - Value : All
    Click "Add", then "Save Changes", then Finish.
    Then you use your custom report on a selection of device (using Report Generator, Inventory, pick your custom template), and you should be good to go. I then export it to CSV for further editing, sorting, etc.

  • Challenge: Spanning Tree Control Between 2 links from Switch DELL M6220 to 2 links towards 2 switches CISCO 3750 connected with an stack (behavior like one switch for redundancy)

    Hello,
    I have an Spanning tree problem when i conect  2 links from Switch DELL M6220 (there are blades to virtual machines too) to 2 links towards 2 switches CISCO 3750 connected with an stack (behavior  like one switch  for redundancy, with one IP of management)
    In dell virtual machine is Spanning tree rapid stp, and in 3750 is Spanning tree mode pvst, cisco says that this is not important, only is longer time to create the tree.
     I dont know but do you like this solutions i want to try on sunday?:
     Could Spanning tree needs to work to send one native vlan to negociate the bdpus? switchport trunk native vlan 250
    Is it better to put spanning-tree guard root in both 3750 in the ports to mitigate DELL to be root in Spanning Tree?
    Is it better to put spanning- tree port-priority in the ports of Swicht Dell?
    ¿could you help me to control the root? ¿Do you think its better another solution? thanks!

  • ISCSI traffic running across Cisco 3750 Switches

    My customer has a small shop with 2 servers runnig iSCSI to a SAN device. They are looking for a switch recommendation and I would like to use a pair of Cisco 3750's, to take advantage of the VSS technology for redundancy,L3 and some other Core requirements, but I am concerned about performance.
    I thought my other option is to use 3750E's but concerned about the added costs.

    The fabric and pps ratings for the 3750Gs don't support wire-rate for more than 16 gig ports. (Max performance for 3750G models is 38.7 Mpps and 32 Gbps fabric; for 3750-E it's 101.2 Mpps and 128 Gbps fabric [NB: pps is enough, slightly insufficent fabric bandwidth for 48 port models - similar 4948 offers 102 Mpps, 136 Gbps].)
    Another performance limitation of the 3750s (and to lessor extent the 3750-Es) is stack ring bandwidth. As best I can tell, the 32 Gbps is really dual 8 Gbps duplex (dual 16 Gbps duplex for -Es). An important distinction between the original StackWise technology and the later StackWise+, the former puts a copy of all traffic on the stack, the latter suppresses unnecessary unicast. The former also requires the sender to remove the traffic from the stack ring, the latter the destination removes the traffic. (I.e. the "+" technology, really is plus.)
    For really, really demanding performance, a stack ring isn't the same as a chassis fabric (e.g. 4500s), and within a single switch, the lower end switch models, they can't always provide wire-rate for all their ports. However, the real question is whether you need this performance in a small shop even though iSCSI is being used.
    In other words, its rare to see all ports demanding full bandwidth, so a stack of 48 port 3750Gs migtht work just fine for your customer if the actual need doesn't require more than the device can supply.
    In similar situations, I present the customer with such facts. Based on what the expected load is, device "A" might work fine, but it can't guarantee performance beyond a certain level. If customer wants the capability for more performance, for growth or "just to be safe", can do too, here's your options (and extra cost) for that too.
    BTW, if SAN devices can support 10gig, then you'll need something better than the 3750G since the model with a single 10gig port has been discontinued.

  • Etherchannel trunk with two cisco switch

    Hi, my company using only one Cisco 3750 switch with VLAN1,2,3,4,5. 
    Now my company bought another cisco switch and we would like to etherchannel trunk between both and create new VLAN in new switch.  We look over from partner, some of them suggested we use LACP, and some of them suggest we use PAgP.  We are so confuse which will be better in our environment.
    Previous: Router <> 3750 switch A (VLAN 1,2,3,4,5)
    Now we bought another Cisco Switch B:  Router <>3750 switch A <> switch B (add more VLAN 6,7,8,9,10)
    Which of below command is the best choice to suit our company ? suppose we use 2 port of gigabitethernet 1/0/1 and 1/0/2 trunk?  All VLAN 1-10 need to communicate with each other.
    interface GigabitEthernet1/0/1
     channel-group 1 mode active  <<< (use "active" or "desirable" is the best choice)
     switchport mode trunk
    interface GigabitEthernet1/0/2
     channel-group 1 mode active
     switchport mode trunk
    interface Port-channel 1
     switchport trunk encapsulation dot1q << (do we need put this? as we think this is by default after trunk?)
     switchport mode trunk
     switchport nonegotiate <<< (do we need "nonegotiate" if both switch setup same configure?)

    Hello
    My understanding is pagp and lacp basically perform the same features - however as PAGP is cisco propriety LACP is IEEE standard which can be used between different route/switch vendor platforms.
    As for disabling DTP ( switchport nonegotiate) - i would agree to do this suggestion, As so not to  have trunks being dynamically created.
    Lastly i would manually prune unused vlans across trunk interfaces, to save on cpu and memory usage because of the stp instances that coild be used ( however such a small vlan database  like yours would not be an issue)
    So to summarise:
    Cisco to Cisco ehterchannels =PAGP
    Cisco to other vendors = LACP
    L2 etherchannel
    ================
    1) default physical interfaces (if possible)
    2) configure port-channel in physical interfaces
    -- port-channel will be created automatically
    3)create trunking encapsulation or access port mode directly in port-channel interface
    4)enable physical interfaces "no shut"
    conf t
    default int ran fa0/1 -3 ( if applicable)
    int ran fa0/1 -3
    shut ( if applicable)
    channel-group 1 mode xxx
    int port-channel 1
    switchport trunk encap dot1q
    switchport- mode trunk
    switchport nonegotiate
    switchport trunk allowed vlan 1-10

  • Stack issue on Cisco 3750

    Hi team,
    I have an issue with the stack basing on Cisco 3750 switches.
    Today on one of them, something went wrong and all ports are down.
    Could you please advise, what happened? In what direction I should work to find root cause?
    thank you

    Hi,
    I have found out what is the root cause.
    In stack, I have 4 switches:
    1. Member
    2. Master
    3. Member
    4. Member
    But right now I have next picture
    1. Member - status "Ready"
    2. Master - status "Ready"
    3. Member - status "Provisioned"
    4. Member - status "Ready"
    5. Member - status "Ready"
    I have checked MAC addresses, I have noticed, that member 3, became member 5.
    For resolving this issue, I just need make member 5 member 3, but I don't know how to do it exactly.
    My plan is:
    - remove member 3.
    - change number of the member 5 to member 3
    Is it correct?
    Thank you,
    Igor

  • CIsco ISE use two different local certificates for EAP

    Hi Experts,
    ISE 1.2.1.198
    It is possible to use two different local certificates on cisco ISE, generated by two different root CA, for EAP?
    Example:
    1 - Microsoft CA for notebooks
    2 - Different CA (public, openssl, other) for mobiles
    And, in case it is possible, which will be the first one presented from the server to the client for EAP-TLS authentication?
    Thanks
    Andrea

    Thanks for your reply,
    i think i'll go for another pair of PSN for the mobiles

  • Up-link 2 x 3750 Stack to 4 x 3850 stack

    All - 
    Sorry is this is a rather simple question but I’ve never worked with Stack switches before? I have a remote office that has 3 floors. On one floor we have a 2 3750s in a stack. On another we have a single 3560 and I’m going to be installing a new 3850 stack – the new stack will have 4 x 3850’s...
    My question is how should I uplink the other switches to the new stack? In the new stack I have a master a slave and two member switches. Should I create a port channel from the 3750’s and use all available links and spread them across all switches in the new stack, and then do the same with the single switch on the other floor? Or should I create two port-channels from the 3750 and the 3560 to the new 3850 stack?
    My thought is that if I create a single port channel form each switch to the new stack I would be basically be removing spanning tree from the environment and basically daisy chaining the switches? Is this a valid solution? Also does the stack act like a chassis where the control plan would be on the master – if so can I spread a interfaces in a port channel across all members in the stack?
    Thanks in advance
    Mike

    To take advantage of fewest (logical) devices and redundancy, run a dual Etherchannel from your new 3850 to the 3750 stack and the 3650.  On both the 3850 and 3750 stacks, insure the same Etherchannel links are on different stack members.
    Logically, you would no longer need STP, but keep in running in case anyone accidentally creates a L2 loop.
    As to what stack members to terminate uplinks/downlinks on, on 3750s, Cisco recommends avoiding the stack master (not possible on your dual 3750 stack).  I don't know what Cisco's recommendations, if any, is for 3850 stacks.
    Yes, stacks "appear" much like chassis devices, i.e. stack member ports "appear" like chassis line cards ports.

  • Uplinks on 3750 Stacks

    We are at the early stages in deploying a Campus LAN, at the access layer we are planning on using 3750 stacks with 2 x 2gb etherchannel uplinks going to diverse core switches; what is the best practice for the cross-stack etherchannel port assignment. E.g. Would it be best to put the first etherchannel uplink on the stack master and the second etherchannel on a non-master switch? Also what are the recommendations for using STP (R. PVST+) or load balancing in this scenario?

    For cross-stack EtherChannel configurations, ensure that all ports targeted for the EtherChannel are either configured for LACP or are
    manually configured to be in the channel group using the channel-group channel-group-number mode on interface configuration command. The PAgP protocol is not supported on cross- stack EtherChannels.
    Here is the procedure from the 3750 12.2.25 docs.
    This example shows how to configure a cross-stack EtherChannel. It
    assigns two ports on stack member 2 and one port on stack member 3 to

  • Throughput of Cisco 3750-E

    Hi,
    Can anyone let me know the actual throughput of Cisco 3750-E (WS-C3750E-24TD-S) Standalone switch and the throughput when stacked with 4 nos of WS-C3750E-24TD-S ?
    Is WS-C3750E-24TD-S ports oversubscribed?
    Sam.

    I think the 68 Gbps backplane supports the 48g port variants plus two 10g ports; i.e. 48+10+10=68.
    What's a bit confusing, fabric specifications are normally "doubled" to allow for duplex ports but Cisco, in the posted spec uses the term "backplane" rather than "fabric".
    Also confusing, when stacked, there's a pair of 16g stack ports too.  It's unclear whether the same backplane or fabric bandwidth is shared with those, or whether there's additional capacity to support them too.  I.e. the 3750-E might support wire rate bandwidth when used standalone but might not when stacked.
    In any case, when 3750-E units are stacked, the stack ring can be a potential bottleneck.  Fortunately, besides StackWisePlus offering twice the stackport bandwidth of StackWise, it also supports (for unicast) destination stripping and also (for unicast) only puts traffic on the stack ring when it must.  Still, again, it's a potential bottleneck.  It's also a ring, not a fabric.
    PS:
    Besides bandwidth, you need to check a switch's PPS capacity.  I believe the 3750-E has sufficient PPS it can generally support wire rate.
    However, one common problem with 2960/3560/3750 series switches is lack of RAM for deep buffering.  The 3750 series, I understand, to have 2 MB per 24 copper ports and 2 MB for the uplink ports.
    The 3750 stacks are often fine for user edge ports, often not so fine for more demanding roles.
    PPS:
    Also believe the 3750-E is end-of-life and end-of-sale.
