I am looking for configuration guide for EX4200 Switch , some configuration are different on EX , for example, EX 4300 vlan l3 interface requires irb interface.
I googled it , all I see hardware guide .
Thanks and have a nice day
Look for original EX Day One book - this covers all older EX products, including EX4200, and takes you through 90% of what you generally need to do.
I just read through it.
But it did not cover sysyem services such as NTP, TACPLUS, SNMP, SYSLOG, I am not sure if they use the same syntax on EX 4200 just like they do on EX 4300.
I did notice EX 4200 Vlan -l3 interface takes vlan.xx not irb.xx as we see on EX 4300.
Which release are you using?
You can check below link.
These services are the same in both switches the change between the two models is in layer 2 switching configurations called ELS (enhanced layer 2 services).
Check out these two free day one books for the next level configurations:
