Cisco and Huawei switch compatibility

Hi all. In our company we are going to implement VoIP in our regional offices were all the networking equipment is Cisco. We were thinking of using Huawei 8 port PoE switches to which we would connect our Cisco phones and then connect the Huawei switch to the Cisco switch using a trunk.
I was wondering if anyone has experience connecting Cisco and Huawei switches? Are there known problems interconnecting these switches and what should I pay attention to on the Cisco side of things?
We mostly deal with Cisco equipment in our company so connecting/configuring Huawei switches is something new for us.
Thanks in advance for any help.

Hi Igor,
As Glen indicated , the main problem is spanning tree. Huawei switches use mstp where cisco has pvst by default.
The other problem is qos on switch ports for IP Phones. Cisco Switches automatically discover and configure some settings for IP Phones but Huawei will not do any of these by default.
If you are planning to use some L3 configuration on Huawei switches be sure that their administrative distances differ from Cisco.For example , static routes have admin distance of 60 :) Also routing protocols have different admin distances as well.
There are many differences on MPLS functions as well , but I guess they are all out of your scope.
Please let me know if you need further information.
Hope to help,
Kerem

  • Trunk between cisco and huawei

    One of my edge Huawei S5700-28C-EI stack switches  is dead, I am going to replace it with a Cisco switch Catalyst 3750 series PoE-48 via a trunk link  with GE fiber port on both ends, please see the diagram below.
                                      trunk                     trunk
       Core switchrouter<----------S5700<--------------->Cisco Catlyst 3750
    I haven’t touch Cisco switch for many years, I would like to ask the following questions:
    1.)      Do I need to take any precaution before connecting this Cisco switch into my Huawei network? Only one link between S5700 and C3750, so I don't need worry anout STP? Do I need to worry about Default vlan regarding trunking port?
    2.)      I need to use different trucking protocol e.g. 802.1Q etc to interconnect these two switches (S5700 and Catalyst 3750), please see the following configuration:
    For C3750:
    switchport trunk encapsulation dot1q
    switchport trunk native vlan (What you want)
    switchport trunk allowed vlan (VLANs required)
    switchport mode trunk
    spanning-tree portfast trunk
    For S5700:
    port link-type trunk
    port trunk permit vlan all
    Do you think the configurations above are right?
    Do I need to manually enter Duplex and speed options ?     
    3.)If the configurations are not right, then what are the commands for trucking port/link should I use on the Cisco switch (it uses IOS software) and Huawei switch?  Procedures of the commands would be really helpful !
    Any information and help would be much appreciated.

    I know the problem,When I change the native vlan of my  S5700-28C-EI ,it's just ok.

  • Compatible between Cisco and Huawei

    Dear Expert
    We have purchased 7 units Huawei access switches, S2700-26TP-EI-AC & 1310 SFP modules from www.huanetwork.com now we plan to add a aggregation switches, for this part, we want to use Cisco WS-C3750X-24S-S, my question is with Huawei GE optical port (with 1310 SFP module), can it connect to Cisco 3750X GE ports (with GLC-LH-SMD). If not we may need to go for Huawei S5700.
    Thanks very much.

    I know the problem,When I change the native vlan of my  S5700-28C-EI ,it's just ok.

  • Cisco Nexus 5596 and Brocade 5300 compatibility

    Hi
    We have designed the SAN network with Brocade5300 connected to Nexus5596. we want to know about the campatibility of these two switches.
    I can't find any compatibility matrix with this detail.
    i would appreciate it if you let me know about your experience.
    Thank you

    Amir,
    Check this.
    http://www.cisco.com/en/US/docs/switches/datacenter/mds9000/interoperability/matrix/Matrix7.html
    I am not sure how recent it is and when this testing was done. I would suggest you to run " Gateway mode" AKA NPIV mode for Cisco and test this with Brocade 5300. It should work fine.
    Hope this helps.

  • Cisco SG300 - IGMP and multiple switches

    Hi all,
    I have read through various Cisco documents and tried various configurations and i have been unsuccessful
    Here is the network layout
    Cisco SG300-10 in Layer 3 mode, managing all VLANS created and inter-vlan traffic is working fine
    Ports 1-4 are in LAG 1 with LACP enabled, Ports 5-8 are in LAG 2 again with LACP enabled, port 9 is connected to the ASA 5505 (Trunk port, all VLANS) and port 10, again a trunk port I use for management
    LAG 1 and 2 are connected to Cisco SG300-52 switches
    again traffic between the switches is working ok, what we would like to do is the following
    on VLAN 7, we have multiple devices streaming using UDP multicast, what we would like to do is allow PC's on VLAN 5 to be able to pick up these streams as and when they need to, the devices broadcast on their own unique UDP ranges
    Could someone please explain to me what I need to configure on the Layer 3 switch and the other two Layer 2 switches in order for this to work?
    If i put a port into VLAN 7 and can view the stream without a problem, also if there is any fine tuning to be done once this is working
    Thanks
    Andy

    Jason,
    The only advantage you would get from using SFPs (fiber tranceivers) in the GBIC slots would be if you needed to make a run of over 100m between the switches.  Unless you have a very large property with switches at either end you are just as well to use the copper ports in the setup you described.  There is also nothing wrong with chaining the SG100s together if necessary to free up a port on the RV320.  The only other thing to consider is if you are using VLANs.  Each unmanaged SG100 will only pass a single VLAN so if you need segregated distribution coming from the RV320 you would need to put each SG100 on its own port.  Or, you could run a trunk from a port on the RV320 to your SG200 and then split off your untagged VLANs from there.  Hope this answers your question and have a nice day.

  • The difference of the IEEE802.1x Auth between Cisco Routers and Catalyst switches

    Hello
    I am investigating the difference of the IEEE802.1x Auth between Routers and Switches.
    Basically dot1x auth is availlable on Catalyst Switches. however if I want to check to
    PortBased Multi-Auth , MAC address Auth and any certification Auth with this feature,
    Is it possible to integrate into Cisco Router such as Cisco 891F ?
    In my opinion Cisco891F is also available to use basic IEEE802.1x but if it compares with Catalyst switches such as Cat3560X
    I think there might be any unsupported feature on Cisco 891F.
    I appreciate any information. thank you very much in advance.

    Many time in interviews asked comaprison between cisco  routers and switches that i was answerless bcoz i dont have much knowledge about that.Can anyone provide me the compariosin sheet of the same.how are the cisco devices differ with each other how much Bandwidth each routres support and Etc...
    Ummmm ... The most common question I get is "what is the difference between a router and a switch".
    However, if you get a question like this, then my impression to this line of questioning are:
    1.  The candidate they are looking for has in-depth knowledge of routers and switches.  And I mean IN-DEPTH!;
    2.  They are not looking for a candidate.  They just want to stroke their ego.  There is not alot of people who can give you the "names and numbers" of routers and switches at a snap of a finger.  And if you do happen to know the answer, then and there, then expect a tougher follow-up question. 

  • Using Cisco MDS 9148 switch for switching and routing

    Hi Gurus,
    Can you please advice me! Can i configure interface trunking, routing and dhcp services on the Cisco MDS 9148 switch?
    Thanks for your response!!

    Tommy,
    MDS9148 is a Storage SAN Fibre Channel switch, it doesn't support Ethernet, IP, VLANs, VLAN trunking, 802.1Q, IP routing, DHCP. It's meant for Fibre Channel connectivity between Fibre Channel server HBAs and Fibre Channel storage.

    Start by working throudh the Troubleshooting iOS and WiFi knowledge base article and see if that helps the situation.  When you get to shutting down the router, be sure to disconnect power as shutdown on some is really just standby mode.

  • Cisco LAN Management Solution is required to support Cisco Nexus 5548P and 5596UP switches?

    Hi,
    Could someone help to know what Cisco LAN Management Solution is required to support Cisco Nexus 5548P switches and Cisco Nexus 5596UP switches?
    These new Cisco switches are being implementing on customer network and he ask us that he requires these equipments be supported on a LMS solution (customer currently is using LMS 3.2.1)
    Can someone help?
    Thanks in advanced,
    guruiz

    Some very limited Nexus support is present in LMS 3.2.1 - see the supported device table here.
    To get more complete support, including the 5596UP, they need to upgrade to LMS 4.x (e.g.  LMS 4.2.2 is the latest and is sold under the Cisco Prime Infrastructure 1.2 umbrella). The major upgrade from 3.x to 4.x requires purchasing an upgrade license.
    Some functions (namely User Tracking ) will not be available on the 5k due to non-support of the requisite MIB on the device. I believe LMS still doesn't let you do VLAN management on 5k's - you need to use DCNM for that if you want to do it from a GUI.
    See the table here for LMS 4.2 device support.

  • LMS 3.2 and Cisco Small Business Switches

    Hi there,
    I'm currently using LMS 3.2 to monitor my network. We've recently purchsed a few of the Cisco Small Business Switches, the SF 300-24 model to be exact. They're considered 'managed switches' (tho thier CLI is terrible) and I would like to monitor them in CWLMS. My problem is that once I add it to CS, it doesn't resolve to anything, just sits there as a blue box with a question mark. I'm assuming this means that these devices are not (currently) supported by LMS 3.2 - do you know if that will change, or how I can go about managing this device with LMS 3.2?
    Thanks

    Unfortunately that series of products is not supported in any version of LMS (or even Cisco Network Assistant - CNA).
    Cisco provides the FindIt utility to manage them:

  • Buffer Misses on Cisco 2970 and 2950 switches

    Hi,
    I am seeing a lot of big buffer misses, some small buffer misses and medium buffer misses on our 2970 and 2950 switches. I'm seeing this on most of our switches (about 10 of them). I've searched the forum and docs and only found info relating to routers. Anybody know what these errors mean and how to troubleshoot them for switches? Thanks in advance.

    One common reason for this in 2950 switches is due to flooded traffic. Plug in a sniffer in promiscous mode and check for any broadcast/multicast/unknown unicast flooded traffic.

  • LAG configuration issue on Cisco SG300 52 Switch

    Hi everybody,
    I am having an issue with LAG configuration on a Cisco SG300 52 switch. I have connected four Ge ports on the switch to the four NICs of a Dell R710 Server on which I installed Windows Server 2008 R2. Without LAG configured, these ports would forward traffic to and from the Dell server fine. However, if I configure LAG on the ports with LACP enabled, then they would not forward any network traffic. Debugging shows that the ports are up but their forwarding status show N/A. Am I missing any configuration? Can I configure LAG on edgeports? Or is there any compatibility issue?
    Any help  from you guys will be greatly appreciated.
    Thank you.
    Vishal

    Hi Dave,
    Thank you for your quick response and sorry to have looked at it late. Well, I already resolved the issue and like you pointed out, it was the configuration of the Dell NICs. I had to configure NIC teaming and there was a bug with the Broadcom NIC management software. I had to download this piece of software again and I was then able to configure NIC teaming on it. I initially thought that it was already configured because we got the Dell server "pre-installed with pretty much everything".
    Anyway thank you for your assistance. Oh I have a question though if you don't mind clearing my doubt. We have bought 7 of these SG300 Switches and I would like to use all of them
    in a hierarchical design as core, distribution and access layer switches because I believe this switch has got all the qualities to be used at all the three layers. We have about 100 users in our company at the moment but expecting growth of about 10-20 employees per year. Would you think a hierarchical network design for a 100 users is a bit of an overkill? Would you think these SG300 switches can handle network traffic at the distribution and core layers? I worked out the average daily traffic is only about 4 Mbps.
    Thank you for your valuable guidance.
    Kind regards,
    Vishal

    Hi Chundunsing,
    Thank you for the purchase of my switch.
    Chundunsing, I love the way you worded your question ; "I am having an issue with LAG configuration on a Cisco SG300 52 switch." ,but seriously you are having a problem with interfacing the dell with my switch.
    You have LAG working to the Dell R710 teamed NICs and god knows what NICs or drivers you are using to acheive this.
    Now LAG is providing , load balancing between the LAG ports.
    Now LAG is providing , link redundancy for connectibity to the Dell R710.
    If there is a configuration issue , it sure seems the way you have it configured without LACP is still working. But you have the option when you create a LAP group to enable LACP. You can see this as a tick box in the LAG group.
    But might i also install, recently firmware version 1.1.1.8, just came out.
    Please be sure to;
    Step 1. update the firmware on the switch and
    Step 2. select it as the 'active image.'
    Step 3 rebbot the switch to utilize this active image.
    If you are having any trouble doing this the admin guide references how to achieve this. for your concenience I have atteched the guide to this posting.

  • What are the major differences between a Access Switch and Aggregation Switch w.r.t Carrier Ethernet domain?

    In a Carrier Ethernet domain,Could someone please help me understand what's the basic difference between Access Switch and Aggregation Switch both in terms of s/w and h/w functionalities. MEF deals OAM,CFM, EVC provisioning only at the access edge switches. Do we need to repeat all these at the aggregation level? or  is it just used for routing purpose? Do we have a separate Fault Management at the aggregation level?

  • Steps to upgrade Cisco MDS core switch

    Hello,
    We wanted to upgrade our Cisco SAN core switch firmware. Currently we are running below firmware version. We wanted to go to latest version NX OS 5.2 (x) but as per the white paper i need to go to 5.0 (X) and after that i need to upgrade it to 5.2 (x). Can some help me with the steps to follow the upgrade. I have th cook book but just need the main steps to perform the upgrade.
    kickstart: version 4.1(1c)
      system:    version 4.1(1c)

    are you using IVR non-NAT, if you are you need to convert to IVR-NAT before you go to 5.2. Other than that you just follow the  normal procedure, look at the release notes for each firmware to make sure your hardware is supported and then do the usual
    install all system bootflash:m9x00-xxx.bin kickstart bootflash:m9x00-xxx-kickstart-xx.bin
    as a side note, i know you don't mark people replies to your questions as helpful/correct on EMC ECN ..at least do it here to show your appreciation.
