Switching

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 ...

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 ...
