2x10GigE will function correctly with all 24 or 48 10/100/1000 ports.

What happens if a 10g card is installed? Do you lose the last two ports?
And is this behavior the same on the 4200?

That makes sense. I'm not at all happy with it, but it makes sense. I'm am
using ge-0/1/0 which must correspond to ge-0/0/20.
Thanks.

Subject: Re: [j-nsp] EX3200 Interface Strangeness
The 3200 is setup so that if an uplink Mod is installed you loose the
last X ports. Example: you have a 24x10/100/1000 with 4x1GigE card.
If/when ports are active on this 4x1GigE card ports 20-23 become
INACTIVE. They are mutely exclusive.

I'm experiencing a weird issue with an interface that seems to have vanished.
(see below 1.)
I also have a general question on how the EX platform indexes interfaces.
(see below 2.)
=================================================
1. Vanishing Interface
I have several ex3200's in production and noticed that ge-0/0/20 shows up in
the config, but doesn't appear to exist.

======================================================
2. Indexing question
During the gathering of data for issue 1 above, I ran some walks against
other ex3200's I have and noticed that the indexing is not consistent.
Here's another ex3200 running the same code rev as above:
ifDescr.148 = STRING: ge-0/0/18
ifDescr.149 = STRING: ge-0/0/18.0
ifDescr.150 = STRING: ge-0/0/19
ifDescr.151 = STRING: ge-0/0/19.0
ifDescr.152 = STRING: ge-0/0/20
ifDescr.153 = STRING: ge-0/0/20.0
ifDescr.154 = STRING: ge-0/0/21
ifDescr.155 = STRING: ge-0/0/21.0
ifDescr.156 = STRING: ge-0/0/22
ifDescr.157 = STRING: ge-0/0/22.0
ifDescr.158 = STRING: ge-0/0/23
ifDescr.159 = STRING: ge-0/0/23.0
ifDescr.160 = STRING: vlan
ifDescr.163 = STRING: ge-0/0/0
ifDescr.164 = STRING: ge-0/0/0.0
ifDescr.165 = STRING: ge-0/0/1
ifDescr.166 = STRING: ge-0/0/11.69
ifDescr.167 = STRING: ge-0/0/11.70
ifDescr.168 = STRING: ge-0/0/1.0
There seems to be no correlation between the ifDescr seq numbers and the
interface names. Now, the switch above has a 4x GE SFP PIC and the one below
does not, but I find it strange that interfaces show up all over the place as
if they were dynamically populated into a table.
==============================================
Sorry for the length of this post.
Thank you for any input.
