    Hi! i have extreeeme 440t-g2-10ge. and this vlan cfg.
    Default 1 10.1.5.254 /21 -f----------T--------------- ANY 7 /19 VR-Default
    GuestWiFi1111 1111 10.111.111.2 /24 ---------------------------- ANY 3 /3 VR-Default
    Mgmt 4095 10.1.5.151 /8 ---------------------------- ANY 0 /1 VR-Mgmt
    PrintersVLAN 10 10.1.10.1 /23 -f-------------------------- ANY 3 /4 VR-Default
    VoIPVLAN 20 10.1.20.2 /23 ---------------------------- ANY 3 /3 VR-Default
    ServersVLAN 30 10.1.30.2 /23 ---------------------------- ANY 2 /2 VR-Default

    and this route cfg

    #s 10.1.0.0/16 10.1.5.31 1 UG---S-um--f- Default 135d:3h:28m:18s
    #d 10.1.0.0/21 10.1.5.254 1 U------um--f- Default 156d:23h:3m:9s
    #d 10.1.10.0/23 10.1.10.1 1 U------um--f- PrintersVLAN 140d:2h:42m:41s
    #d 10.1.20.0/23 10.1.20.2 1 U------um--f- VoIPVLAN 0d:2h:56m:39s
    #d 10.1.30.0/23 10.1.30.2 1 U------um--f- ServersVLAN 27d:21h:40m:15s

    if I connect to the port (untagged) a laptop on which there is a server (VLAN), then it will receive settings for dhcp, but does not ping the gateway (VLAN interface). Accordingly, no equipment is pinged further either. How to solve this problem. Before I installed the latest firmware, everything worked. I don’t want to return the old one. There was a slower functioning web interface.

    help me please!!!

    do you have "ip forwarding" enabled on the vlan ip-interfaces?

    yes, i do that and i have vlan cfg that
    Default 1 10.1.5.254 /21 -f----------T--------------- ANY 7 /19 VR-Default

    Can you be a bit more specific. Which port are you plugging in to with the station, which port is the server located on and which subnets does DHCP offer addresses for? What's the IP of that server? Can you paste the entire config?

    Eric, the MICROTIK router is a dhcp server. Each port on the router has its own vlan and interface, each bridge has a bridge, each bridge has dhcp servers with their pools. On the extreme, the same vlans are created. I am pinging the gateway on a microtic (10.1.20.1 or 10.1.30.1) from the commutator, but the devices that received the address (the phone and the computer do not respond).

    Try a "show iparp" on the extreme and make sure your devices/IP's are showing the vlan's you expect. Also do a "show fdb" and confirm the same for mac's alone. Can you ping the router from the switch virtual interfaces? You can force them to cross the same subnet "ping 10.1.20.1 from 10.1.20.2" or "ping 10.1.30.1 from 10.1.30.2". Should help you to isolate a bit more.

    Yes, you understand me correctly. The address of the phone and computer comes to the arp table, but these addresses are not responding to the extreme.

    I can say that now from 10.1.31.254 (computer) I ping 10.1.30.2 (extreeme), but I do not ping 10.1.30.1 (mikrotik), from the default VLAN I ping 10.1.30.1-10.1.30.4 (mikrotik-extreeme)

    Hi,

    1) You changed firmware on extreme ? If yes what is new ver. and what was the old one ?
    2) If you have ACL, check if they are all applied after upgrade.
    3) On mikrotik you have packet analyser for example torch.
    Run it on the interface and check if you see any packet from computer/test host,etc.
