HI Tore, You are not oversubscribing that 'pic'. There is a bandwith of 14ge per 'pic' (per 10x1ge port, or per 1x10ge port).
When you then create a tunnel interface on a pic with 10x1ge port, you still have more then Enough capacity to create a 11th phantom port, without loosing capacity or oversubscribing. This is also the reason, with a 4x10ge card, that you have to sacrifice 1 physical port. There is not enough spare bandwith to allocate a phantom port... Anyway, the explanation I made is definatly valid for 40x1ge and 4x10ge. With the mixed cards I can't be sure, since I haven't used them yet... Hope this helps, otherwise let me know.

I think you might have the DPCE-R-Q-20GE-SFP? But in any case I think they're likely to work the same. Thanks for your reply! > fpc 0 { > pic 1 { > tunnel-services { > bandwidth 1g; > > Interface will be: ip-0/1/10 Interesting. So you're still able to use all physical ports (ge-0/1/0 through ge-0/1/9) as before; you've actually oversubscribed the PFE by 11:10? That can't be done on the 10 GbE PFE, enabling tunnel services deactivates the physical port completely. :-( Best regards, -- Tore Anderson Redpill Linpro AS - http://www.redpill-linpro.com/ Tel: +47 21 54 41 27 _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
