inter-vlan routing between stacked and standalone x450e switches

  • 1.  inter-vlan routing between stacked and standalone x450e switches

    Posted 06-06-2018 18:23
    I have an existing stack for the access layer and want to add a TOR switch.
    All x450e 12.6.2.12
    configured vlans to match the stack
    removed all ports from default vlan(matching the old stack)
    enabled IP forwarding
    routes show the existing stack vlan gateways and the new interface ips for the vlan

    I didn't really want to assign IP address to the vlans on the new TOR switch, but it seemed to be required.

    I believe I am missing a key concept on how vlan does its routing(am cisco guy, this is my first extreme shop), does anyone know of a good guide/cookbook to config this specific scenario?
    I feel like I should add the vlan gateways from the stack, and be good to go... but that failed on my first go.

    There are sort of a lot of questions here. But your Core, or Router/Routers should be doing the routing. If all VLANs (VLAN tags) match are are added tagged on both ends of the uplink you should have layer 2 connectivity.

    Typically I would add a NetMgmt VLAN with an address to reach and manage the TOR switch, no other VLANs would have IPs.

    Since you're coming from Cisco, I would check that you added all VLANs tagged on both ends of the uplink first. Cisco trunks everything so that would be easy for you to miss.

    Indeed, so many questions so I am trying to learn extreme basically by reverse engineering the existing equipment. Are there some better commands to show port:vlan settings? I get the long output from the 5 sw in the stack, but I am having trouble finding just a comprehensive 'this port is a member of these vlans,' (4 vlans but doesn't tell me which vlans unless its a single vlan)

    And just to be clear: Trunking on extremes is just adding a port to more than one vlan, tagged?

    Some of my favorite doing network connection and discovery with examples

    here is a jumpstart guide that gives you a lot of the basics.... All so remember tab is your best buddy

    show edp port all detail ... this will give you neoghbor detail about any two extreme switches that share a link including the vlans that are share don the link..
