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. -b -----Original Message----- From: Mike Mainer [mailto:[email protected]] Sent: Monday, August 17, 2009 7:39 AM To: Bill Blackford 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. -Mike Mainer Bill Blackford wrote: > 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.
