[j-nsp] ARP resolution algorithm? Storage of MX transit packets?

I am trying to wrap my head around how the MX handles ARP resolution, and how it stores packets waiting to be transmitted, while waiting for ARP to resolve. If a transit packet comes into a router, on a PFE, and there is no corresponding entry in the ARP cache for the next hop, the routing

Hey everybody-- It's looking more likely that I have a cable issue, here, and just need to get that replaced. I've got two dozen LC cables around here. Fat lot of good that does me, now. Appreciate everybody talking me down from the ledge. Have a great week. --Dave Peters

Hi, Just to close the loop on this, according to JTAC, the throughput issues observed are addressed in KB33477 (basically, wire speed can be achieved on > 96 byte packets). > On Jan 24, 2019, at 9:43 AM, Jason Lixfeld wrote: > > Hey Adam, > >> On Jan 24, 2019, at 5:51 AM, >> wrote: >>

Re: [j-nsp] SRX1500 (pkt mode) dhcp relay and VoIP phones

To close the loop on this, it turned out to be the global l2-learning mode on the SRX1500.  It is set by default in transparent bridging mode. Changing this to switching mode cleared up the DHCP broadcast response that the VoIP phones were having..

After bringing up the same config (Expect we use LR4 Optics) and same OS level for over 12 setups in the past 2 months we did run into one problem that looks similar to this. We would get a link light but the interface would remain down First Make sure to check to see if you are seeing

Re: [j-nsp] MX960 power supply stopped during ISSU

Thanks Tim, unsure what you mean by "do you have enough power supplies to maintain N+1 at full tilt?" Thanks Jerry, ISSU upgrade went fine this time. I've done 3 so far... -1st MX960 ISSU upgrade in lab-960 was fine -2nd MX960 ISSU upgrade had a glitch, I don't recall why, but it

Not sure if this is the problem... maybe it's the laser thing Jerry mentioned, ... but maybe you need to online the mic ? I think I had to do this with new mpc's I put in my mx960's but unsure if it's required at the mic level for newly inserted mics... Request chassis pic online or something
