[j-nsp] Number of logical interfaces for EX switches

[Jerry Jones]

2200 hundreds
3300,4500 around a thousand
4200 thousands

These should be safe, but again your SE can really help you out here.

Thank yo very much!

I have one more concern about scaling. What would be the maximum number Firewall Filter terms per system? I mean if I put several big prefix lists and apply an accept/drop actions on them will it be possible to have a total of a few thousand entries? 

Thanx in advance

Hi Emil,

This will be different for each model. Most are in the 500 range per pre, some can do around 1k.

Get hold of your Juniper SE and he can help you out with scaling questions. I would say most models are safe to 400, but over that you should verify and test.

Good luck.

Hi Troy,

Unfortunately it is not so simple. There are 4096 VLAN IDs and you can
create that many VLANs in the system doing L2 bridging on them. If it is
possible to assign an operational IP interface on each of them is subject
of availability of another resource called IFL's. I don't know how many
IFL's are there in an EX3200.

Anibody with an idea?
