Re: SRX300 series VLAN interface

Hello,

I would like to inform you that starting from version 15.1X+ the vlan interface is no longer supported on SRX and instead irb interface will be used for the same purpose.

You can use the following online converter tool to convert the configruation from the old configuration to the new supported configuration.

https://www.juniper.net/customers/support/configtools/elstranslator/index.jsp 

Or you can refer the below example for your configuration :-

root@SRX320-Pro# show interfaces
ge-0/0/0 {
unit 0 {
family ethernet-switching {
interface-mode access;
vlan {
members mgmt;
}
}
}
}
irb {
unit 100 {
family inet {
address 10.219.33.8/26;
}
}
}

root@SRX320-Pro# show vlans
mgmt {
vlan-id 100;
l3-interface irb.100;
}

You need to use irb interface in a zone for allowing the host-inbound traffic.
Also When you configure a device as Ethernet switch , the mode changes to mix mode and during commit a warning will be seen for a reboot so you need to also reboot the SRX for this configuration to take effect.

If nothing from the above works then refer the following document which is for EX series device but will be same for the SRX 320 device.
