    Hi Johnny,

    The Graphic you shared shows that nothing is connected to the switch. 

    Typically the default configuration will allow the switch to obtain an IP address via DHCP on the default vlan. This is applied to irb.0.

    You would use this IP address to access the J-Web portal via the local network. 

    You can also connect to the MGMT port (vme.0) and follow the above/same procedure.

    NOTE: EX3400s don't typically come installed with J-Web by default and you will be asked to download and install this on the first connection to the J-Web portal.

    Regards,

    Gavin White

    Hi Gavin,

        Thanks for reply. ex3400 rear con port connect to pc, rear MGMT port and front ge-0/0/0 port and pc port all connect to another switch which has a DHCP Server connected, the ex3400 seems didn't get an IP, so I tried to configure management IP for network connecting but without success, don't know why it didn't work. I search Google and even ask ChatGPT but still failed......

    Hi Johnny,

    Sorry you are having trouble with this initial setup. If the device is in factory default this should be as straightforward as you expected.

    I see your interface irb.0 has an interface 192.168.1.97, is this the IP you configured manually? are you able to ping this IP? Are you able to ping other IPs from the switch?

    For further troubleshooting we will need to look at some configuration and basic switching status to check everything is in order....

    `show ethernet-switching table`

    `show arp`

    `show configuration services`

    `show configuration interfaces irb`

    `show configuration interfaces vme`

    `show version | match web`

    Regards,

    Thanks for your kindly help. it took me a week to configure and test this device but still not figure out what's wrong?!
