VSF network design and implementation

  • 1.  VSF network design and implementation

    Posted Jul 29, 2017 11:53 PM
    I've read the documentation about the vsf, and I got some little knowledge on how it works but I'm not sure if I can apply this to our network

    I am planning to implement a vsf on our network and currently we have a 2 core 5406 aruba switches and 4 2530(not sure on model) aruba access switches.

    The document says that it is highly recommended to use MAD.

    Am I going to implement MAD on all our access switch? Or in one switch?

    Thanks

    #5400

    MAD will be working between the two 5400 switches.

    Either you can connect them back to back via OOBM ports or via third switch if you want to use LLDP MAD.

     

    Access switches does not need to be aware of that MAD stuff.  Sole purpose of MAD is to detect split architecture (VSF links goes down and both switches in VSF fabric become active).

    Thank you so much for your explanation , I didn't know I can configure VSF with OOBM port

     

    Do you know where I can configuration example for VSF with OOBM MAD?
    with detailed explanation like with documentation about VSF with LLDP MAD. 

     

    I'm planning to use the 2 OOBM ports for VSF.

     

    Thanks!

    Im starting to get this VSF on how it works however i want to clarifiy some things before I put it into action. 

     

    1. Given that I have 2 5406 aruba switch with OOBM MAD configured, how many VSF link should I implement? I'm thinking that it should be only one but I was wondering if I can implement two VSF link, one link will act as primary link and other will be backup.

     

    2. If Im going to implement the OOBM MAD with this configuration,the management ip address for member 1 is 10.30.31.1 and 10.30.31.101 for member 2? correct me if im wrong , but I've read some articles that I should disable the management vlan if im going to implement VSF.

    oobm
       ip address dhcp-bootp
       vsf member 1
          ip address 10.30.31.1 255.255.255.0
          exit
       vsf member 2
          ip address 10.30.31.101 255.255.255.0
          exit
       exit

    3. If Im going to implement STP / LACP on the other switches , is there any special procedures when dealing with VSF?

    Thanks you for your response.

    1. It is always recommended to implement VSF link as a port channel. All traffic (Control & Data) between the two switches will be passed through this link.

     

    2. I dont see any reason to disable management VLAN. From the forum, below is a sample config for reference:

    vsf
       enable domain 1020301
       member 1
          type "J9850A" mac-address 40a8f0-9dee00
          priority 255
          link 1 1/A21
          link 1 name "I-Link1_1"
          exit
       member 2
          type "J9850A" mac-address 3ca82a-44ad00
          priority 128
          link 1 2/A21
          link 1 name "I-Link2_1"
          exit
       oobm-mad
      exit
    
    oobm
       ip address dhcp-bootp
       vsf member 1
          ip address 10.30.31.1 255.255.255.0
          exit
       vsf member 2
          ip address 10.30.31.101 255.255.255.0
          exit
       exit
    
    no allow-v2-modules

     

    3. Other switches will see VSF fabric as a single switch. You shoudl be find using STP/LACP.
