EX3300 - out-of-band interface not working



  • Hello,

    I had problem with configuring out-of-band interface. First of all I`ve never worked with any of Juniper producst before. Also I enherited this infrastructure after previous employees so it was already set-up and configured.

    VLAN 1    - 192.168.200.0/24 (Native vlan)
    VLAN 20  - 172.16.20.0/24 (PC vlan)
    VLAN 221 - 192.168.221.0/24 (MGMT vlan)

    actual configuration –>

    me0 {
            unit 0 {
                family inet;
            }
        }
        vlan {
            unit 0 {
                family inet {
                    address 172.16.20.254/24;
                }
            }
            unit 1 {
                family inet {
                    address 192.168.200.254/24;
                }
            }
        }
        vme {
            unit 0 {
                family inet {
                    address 192.168.221.16/24;
                }
            }
        }
    }

    Before I had working SSH and HTTPS but to the IP 172.16.20.254 which I do not want because we have dedicated MGMT vlan for MGMT interfaces of network devices.

    So in webinterface I found TAB management access, changed it and commited it. But then HTTPS access stopped working, right now I can use CLI but still only via 172.16.20.254

    I would like to de-configure 192.168.200.254 and 172.16.20.254 from the switch and use only 192.168.221.16 on MGMT interface for managing this switch.

    below is detailed interface configuration…

    I would be very grateful for any help how to troubleshoot and configure it… I can draw also small topology if something is unclear.

    Thank you
