    Hello,i have an extreme switch x440-g2.
    i try to put an ip in the mgmt vlan, but after doing that, switch does not ping.
    After i enabled dhcp, and i have communications by the default vlan.
    I need to set an specific ip for Mgmt, and i cant do that. Can someone help me please.

    Hello tunfas, I've updated the topic title to better fit the question you've asked. I hope that's okay.

    That said, the mgmt vlan is special in that it ONLY works on the dedicated MGMT port on the front left side of the switch.
    Check out these two articles to see if they help with your issue.

    Hello, sure, no problem at all.
    So let see if i got it right. If nothing is connected to mgmt port, i can use the default vlan , there will be no issue?
    Thank you very much for the reply

    I think you've got it right :)

    The mgmt port is for a truly out-of-band management network. If you don't have a separate network for that, then the default VLAN (or another that you create and tag/route across the network) will work fine.

    Hi, since Mgmt vlan belongs to another Virtual Router (VR-Mgmt), you have to specify the vr name when pinging an outside ipaddress throught Mgmt vlan. Otherwise the ICMP request will use VR-Default.

    ping vr vr-mgmt

    Henrique, thanks for this - I didn't know this. Is there anything similarly special we need to know about incoming ethernet traffic on the Mgmt port/vlan/vr?

    I'm also trying to troubleshoot ICMP and IP(telnet) connectivity from a PC (configured 192.168.1.2/24) to the Mgmt port (configured 192.168.1.100/24) on an EXOS switch. The connection is a direct ethernet connection right now. When I ping using your format above, I get:
    * X440G2-12p-10G4.2 # ping vr "VR-Mgmt" 192.168.1.2
    [/code]Ping(ICMP) 192.168.1.2: 4 packets, 8 data bytes, interval 1 second(s).
    --- 192.168.1.2 ping statistics ---
    4 packets transmitted, 0 packets received, 100% loss
    round-trip min/avg/max = 0/0/0 mst[/code][/code]and when I ping from the PC, I get:
    C:\>ping 192.168.1.100
    Pinging 192.168.1.100 with 32 bytes of data:
    Request timed out.
    Request timed out.
    Request timed out.
    Request timed out.
    Ping statistics for 192.168.1.100:
    Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),
    [/code]I've confirmed the (windows) PC has a route to the EXOS Mgmt ip address:

    * X440G2-12p-10G4.2 # sho iproute vr "VR-Mgmt"
    Ori Destination Gateway Mtr Flags VLAN Duration
    #s Default Route 192.168.1.1 1 UG---S-um--f- Mgmt 0d:22h:2m:35s
    [/code]#d 192.168.1.0/24 192.168.1.100 1 U------um--f- Mgmt 0d:22h:2m:36s

    I think this is ok, though for what I'm trying to do (simple access to Mgmt port - no routing required)

    Anything else you can think of that I should check? Thanks.

    My problem turned out to be caused by a bad physical ethernet connection. Please disregard.

    When do you see that message appear? Do you have a rip configuration present on the switch?

    Well, it seems i´ve overcome this step.

    Now i have a static ip on deefault vlan as desired.
    I´ll proceed with the rest of configurations.

    Thank you all for the support.
