[j-nsp] RES: QFX5100 vs ACX5048

[Aaron Gould]

I think I was originally on D20, and had the arp issue… PR1271100 … https://prsearch.juniper.net/InfoCenter/index?page=prcontent <https://prsearch.juniper.net/InfoCenter/index?page=prcontent&id=PR1271100> &id=PR1271100 

--- I think arp issue is seen in queue 27 (start shell…. Cprod command to see it)

 

I think we went to D51 to solve arp issue.  I recall D51 killing my ability to do dhcp-relay.  We do dhcp-relay for residential broadband… pretty sure D51 testing was great UNTIL we saw dhcp-relay broken.

 

We went to D61 and that’s where we sit now.

 

What is “vlan-leaking” ?  Do you have a Juniper PR describing it please ?

 

I look into a preso I had and also this site… https://packetpushers.net/juniper-enterprise-serious-campus-networking/ 

…and I see mention of the chip for the ACX5448 possibly being Qumran-based.  Not sure if that helps y’all.

 

I did also see on a juniper.net spec sheet that throughput for acx5048 is 1.44 tbps and acx5448 is 800 mbps.  I’m wondering why is the ACX5448 less than ACX5048.  I thought ACX5448 was supposed to be better, next iteration of ACX5048/96.

Alexandre,

 

The 15.1X54-D67.2   Fixed this issue for Us, and when I first got this issue, they give us  a "workaround" that disabled the default arp policer and solved the l2 circuits issues with arp packets.

Aaron,
I am using 15.1X54-D51.7, I will try D61.6 version, Let´s see.

                I moved out all Carriers NNI almost 2 years ago and never change anymore since that fatidic day, now the impact will affect only ethernet l2circuits.
