EX4300 QSFP ports and breakout cables

‎11-27-2018 05:54 PM

Hi Guys,

              I am trying to find out whether the QSFP ports on the back of the EX4300-24P switches support breakout cables?

 

I can see from older posts that back in 2014-2016 that it was not supported then - as listed on the old datasheets - as there was a clause that said they were not supported. This does not appear to be in the manuals or setup info anymore.

 

I have no idea of hardware of firmware on the pair of EX4300's that I have, as they are still in the box waiting to be commissioned.

 

Any help here would be appreciated.

Under at least 17.3 there is no channel-speed option on the EX4300, so I'd guess still no.

 

test@test# set chassis fpc 0 pic 1 ? 
Possible completions:
+ apply-groups         Groups from which to inherit configuration data
+ apply-groups-except  Don't inherit configuration data from these groups
  mlfr-uni-nni-bundles-inline  Number of inline multilink frame relay UNI NNI bundles
  no-multi-rate        Disable multi-rate mode
> q-pic-large-buffer   Run in large delay buffer mode

As a matter of interest is that port still setup as a VCP port (which is the QSFP port default)?

Last time I got information on this subject, I was told it is a hardware-limitation in the switching ASIC used in the EX4300 - so the QSFP ports will never able to be channelized into 4x10G.

Nope, they aren't.
