Dear all,I will buy juniper 2x Ex2300 or 2x Ex 3400.I want to use virtual chassis in those two switches(only two switch).when i read data sheet and tech book,it is not clear.So i would like to knowCan i use copper (Rj45)ports as VC port in those model?Can i use one interconnected link between two switches if i don't care reduandancy?If i use one DAC cable for VC internconnect, it us enought for two swiches(i use two switches only to run VC)?If i need 3x10G port for data connectivity and i want to run virtual chassis in,two switch,Ex2300 is correct model,for,me?
QFX5200, EX3400, EX3300, EX2300, and EX2200 switches cannot be part of any mixed Virtual Chassis. Multigigabit EX2300 switches can form a Virtual Chassis composed of only EX2300 multigigabit switches, and cannot be mixed with other EX2300 switches in a Virtual Chassis.
If you want to have one virtual chassis between two EX2300 & other virtual chassis between EX3400, then that is possible.
On ES2300, you can not use RJ45 ports as VC port.
If you need 3 x SFP+ per switch, i will recommend the EX3400 as it has 2 x QSFP on the back specifically for interconnecting VC-members. Then you can keep the 4 x SFP+ for revenue ports.
Designing a solution without redundancy on VC links is far from good practice.
You would buy 2 x EX-QSFP-40GE-DAC-50CM as the cheapest way to interconnect them on the back.
Bonus info; remember that EX2300 requires an extra license per virtual chassis member (EX2300-VC) where it's included on the EX3400. If you are focused on EX2300-24T and EX3400-24T this will end up with roughly the same price for these due to the cost of the VC-license on the EX2300 series.
Can I use copper (Rj45)ports as VC port in those model? NOCan I use one interconnected link between two switches if I don't care redundancy? YESIf i use one DAC cable for VC interconnect, it us enough for two switches(i use two switches only to run VC)? YESIf i need 3x10G port for data connectivity and I want to run virtual chassis in,two switches,Ex2300 is correct model, for me? => NO, you would need EX3400 or EX4300
Future plan is for EX2300-MP to be able VC with EX2300 [standard]. EX4300-MP will VC (today) with EX4300 [standard] but down the road, since no EX3400-MP version, plan is to make EX4300-MP VC additionally with EX3400 [standard]. FYI
