On a 3825 can I use the SFP and the fixed lan ports at the same time?

Hello Mark,
the answer is no
I did a test on a C3825
on int g0/0 there is the media-type command with options rj45 or sfp
on int gi0/1 there is the media-type command only with option rj45
router(config)#int gi0/1
router(config-if)#med
router1(config-if)#media-type ?
rj45 Use RJ45 connector
router(config-if)#int gi0/0
router1(config-if)#med
router1(config-if)#media-type ?
rj45 Use RJ45 connector
sfp Use SFP connector
this means the SFP is linked to g0/0 and that you can use one SFP and one RJ45 port at the same time
Hope to help

I am replacing a router with 3 lan interfaces and going to a router with 2 lan interfaces. My problem is that I need to keep all three networks separate.
I was thinking about using subinterfaces and then on the switches creating a trunk port and using private vlans to keep the traffic separated between the three networks.
What do you think?

Nevermind you can not.
