Hi,Can we configure any other port as management port on SRX3400 then the FXP0?Regards,
Yes you can manage the SRX (SSH/Telnet/SNMP/etc) via a revenue/normal port. The fxp0 interface is intended for Out-of-Band management access, meaning that you have a separate network just for management purposes and your management traffic wont be mixed/affected by your production traffic. If you ever have a problem on the production network, like a broadcast storm, you wont lose management access to your SRX.
You could also have a revenue port working as a Out-of-Band management interface by placing it in the "management" funtional-zone. Note this type of zone is different from a security-zone and any traffic reaching the SRX via the management funtional-zone wont be routed to other zones, it will be only useful for managament of the SRX.
