[j-nsp] Immediate aging in EX-3200

[Dan Farrell]

Well, to clear something up on this I'll just copy my convo with a Juniper person via email verbatim here-

<convo>
-       What are the total number of VLANS that can actually exist on a physical port (when configured as trunk)?
-       What are the total number of RVI's that can be configured on an EX device?

4000 VLANs on a given port (and in a system)
and 1000 RVIs.
</convo>

So it's not a VLANs per interface problem, unless you have more than 4k VLANs on the entire system (and you can really only have something like 93 or 94 more than that anyway).


Are you seeing anything in your syslog entries?

Personally, on my EX's, I'm running JUNOS 10.0S1.1 because it's the recommended release- I looked over the differences in 10.1 and 10.0 and couldn't find anything changed/improved that's relevant to my network. I'd recommend the same for yours.

Hi,

There is no link flap. At the same interface I have about 1000 other
VLANS and about 5000 other MAC's and they don't flap. The problem
affects only a one or a few MAC's at a time.
I should double check for a bridging loop but I don't believe there is one.

I use Junos 10.1R1
