How to use MVRP to propagate Vlans from the X460G2 to the X440G2?

    I have a deployment with X460-G2 as Distribution switches and X440-G2 as Edge switches, I tried to use the MVRP to propagate Vlans from the X460-G2 to the X440-G2, the vlans are propagated but I couldn't use these vlans on the x440G2, any body have a solution?

    I believe you need to actually create the VLAN on the access switch to add it to a user port. It has been a while since I tested MVRP but I am fairly sure that is how it worked in my lab. If you could provide your code version someone might have more current information.

    MVRP does create VLAN on the switch dynamically.

    For vlan assignment to access port you need static vlan.

    MVRP does help you on distribution switches. On access switches or if you need to route the vlan, you need to define vlan statically. (For example by Extreme Management)

    Hi,

    what is your experience in the field with MVRP ?

    Do you have productive environments running with MVRP ?
    Also in conjunction with netlogin (and dynamic VLAN assignment) ?

    I am interested about good and bad experiences caused by dynamic/automatic VLAN Assignment on Interswitch-Links based on MVRP (Core - Distribution - Access).


    BR,

    I have not rolled MVRP out in a customer network yet. I have done some testing with MVRP on some switches at the office and it seems to work without issue.

    I have not used it in conjunction with Netlogin though.

    Today i try it with netlogin and policies - no problem, works good.

    One big negative point is that you cannot assign VLAN to ports manually:

    * X440G2-12p-10G4.8 # conf vlan 1676 add port 2 untagged
    VLAN 1676 SYS_VLAN_1676: VLAN SYS_VLAN_1676 is created dynamically, can't configure ports manually on this VLAN.
    Error: The VLANs specified could not be configured.
    * X440G2-12p-10G4.9 # [/code]
    Is there a meaningful reason why i cannot assign that dynamic (via MVRP) created VLAN manually to a port ?
    For me this is a unnecessary limitation of VLAN handling. And maybe one of the reasons why nobody use MVRP ...

    I too have run into that, and agree that if the VLAN is on the switch dynamically it would be nice to have the option of adding it to a port.

    I think this was designed more for inter-switch connections and I am not aware of many recent updates to it.

    Hi David,
    i found a way to bypass this problem.

    if you rename that dynamic vlan - status will be canged like a "non-dynamic" VLAN and i can add it to a port.

    https://gtacknowledge.extremenetworks.com/articles/Q_A/MVRP-vlan-management/?l=en_US&fs=RelatedA...

    * X440G2-12p-10G4.3 # conf vlan SYS_VLAN_1651 name Lab-MN-1
    * X440G2-12p-10G4.5 # conf vlan 1651 add port 2
    VLAN 1651 Lab-MN-1: Port 2 untagged has been auto-moved from VLAN "Lab-MN" to "Lab-MN-1".
    * X440G2-12p-10G4.6 #

    VLAN 1651: sh vlan Lab-MN-1
    VLAN Interface with name Lab-MN-1 created by user
    Admin State: Enabled Tagging: 802.1Q Tag 1651
    ...
    Ports: 2. (Number of active ports=1)
    Untag: 2
    Tag: *12H
    Flags: (*) Active, (!) Disabled, (g) Load Sharing port
    (H) Dynamically added by MVRP[/code]Port 2 = Access / Port 12=Uplink

    I ask if this will be expected behaviour or do i use a bug ??

    That sounds familiar, I believe I did see that in the past.

    Thanks for the reminder.
