    Hi,

    we have Aruba 2930 series and then we replaced with Aruba 6200 . the CX-OS is totally different when you come to manage your switch (GUI or Telnet).

    usually in 2930 switch:

    1- I create the MGMT VLAN.
    2- assign an IP address and the default-gateway For MGMT VLAN.
    3- on the up-link port, tagged all the VLANs and untagged MGMT VLAN only.

    but here in 6200 its different !!

    I can assign an ip address to the VLAN interface but can not found (Default - gateway) in the switch in the (cli or GUI) !!

    i can only manage it through the MGMT interface !!

    i wonder if there is another way to manage it ???


    Thank You....

    6200 has a mgmt port and this is in the mgmt vrf
    It also has a  default vrf essentially data ports

    to configure management port "out of band"

    conf t
    int mgmt
    ip static <YourIP/Mask>
    default-gateway <YourGateway> 

    DHCP is also an option on the mgmt interface

    if you want to manage it in band then take a regular port and/or trunk and assign a VLAN & SVI and manage it that way. You will need to create some static routes to your management system.

    If you want to create a default static route. This is an example only and in no way takes into account your set up. Only do this with caution

    ip route 0.0.0.0/0  <MyNextHop IP address>

    You should really at least use a more granular approach if you are going to use this in band method, rather than the catch all I've shown above. This is only an example

    Thank you Kamal Takodra for reply.

    all the routing process (L3) are handling by the core switch.

    if I make a static route as you said , that's mean I have to do SVI for each vlans in the edge switch for routing.
    in this case, all the routing process between the vlans will be on the edge switch not the core. and I have to do the same for all the edge switches. this will segregate the network and it will be difficult.

    I can not believe that there is no way to access the switch remotely to manage it !!!!!

    To manage in band you only need to create a single SVI  on a specific vlan  you use for management and then allow that vlan as part of the trunk to your core.

    Then make your your the next hop the core for that vlan

    Here is a fictitious example....to give you an idea

    vlan 100
    name MyMgmT

    int vlan 100
    description mgmt SVI
    ip address 1.2.3.4/X

    int 1/1/52
    description uplink to core
    vlan trunk allowed 100, X,Y,Z          where X,X,Z are other vlans that are layer 2 connected to your core  


    ip route 0.0.0.0/0  <MyNextHop  L3 core IP address for Vlan 100>
