We have seen Cisco copper 10/100/1000BaseT SFPs (GLC-T, SFP-GE-T) work only in 1000BaseT when inserted into MX routers, like Juniper's own SFP-1GE-T. So, we also have some Juniper SFP-1GE-FE-E-T which work in 10/100/1000, in order to cover all scenarios. -- Tassos _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
