For me, the MX304 should, really, be an alternative to the MX10003, and 
not an upgrade of the MX204.


Far easier to get more MX204's than even one MX304 :-).



What does the ACX7100 have in terms of FIB/RIB ? Juniper is making it very hard 
as of late to find that information. I'd be curious if the ACX could do brder 
router duties with multiple full BGP feeds (which the MX204 has no problem with 
at all)


The ACX7100 is an x86-based system with 32GB of RAM. It ships with a 
Broadcom J2 chip. Aggregate capacity is 4.8Tbps. FIB is 1 - 2 million 
entries.


There is a bunch of timing in the box, so you can guess whom it's aimed at.

Try FlowViewer (analyzing, graphing, tending software) + SiLK (robust, 
high-performance capture software from Carnegie-Mellon).


Pretty full netflow analysis package; free.

See: http://flowviewer.net

Re: Juniper MX204 allow oversubscription?

[Randy Carpenter]

If additional ports are more important than the full 100G throughput, you can 
configure it as 2x100+2x40+8x10.

We tend to break out 10G ports on switches, so we can more fully utilize the 
100G ports.

My hope for a successor (MX205 ?) would be more flexibility and 25G ports. 
4x100G+8x25G would be awesome.

thanks,

Re: Juniper MX204 allow oversubscription?

[Kevin Shymkiw]

Adam,

Simply put - No there isn't a way to oversubscribe the front panel.

Juniper has a handy tool to check your port combinations though -
https://apps.juniper.net/home/port-checker/index.html

The lack of being able to oversubscribe has to do with # of lanes to the EA
ASIC, and how those can be broken down.

Juniper MX204 allow oversubscription?

[Adam Thompson]

Hi all,
Hoping some Juniper-using folks know:
On the MX204, which comes with 4x100G + 8x10G ports, you can only use 3 of the 
4 100G ports if you want to use any of the 10G ports at all.
Supposedly this is to prevent oversubscription on what is a 400G-rated router.  
However, I’m perfectly fine with oversubscription with a 400G aggregate 
throughput cap.
Is there a way to stop the automatic “oh, I’ll disable these other ports for 
you so you don’t oversubscribe the box” behaviour and let all the front-panel 
ports be used at once?
