As far as I know there is no way to set the link speed (only the link-mode for duplex) on the underlying interfaces in a AE bundle (and they are always labeled xe-), at least on the code I am running on the QFX5100-48T. You ca specify the link-speed for a AE interface which I presume sets the speed of the underlying bundled interfaces, but I have not tested this out as I have no EX switches.
set ae9 aggregated-ether-options link-speed ? Possible completions: 100g Links are 100G 100m Links are 100M 10g Links are 10G 1g Links are 1G 40g Links are 40G 50g Links are 50G 80g Links are 80G 8g Links are 8G oc192 Links are OC-192 Chris -----Original Message----- From: juniper-nsp [mailto:juniper-nsp-boun...@puck.nether.net] On Behalf Of Tobias Heister Sent: Wednesday, November 04, 2015 10:28 AM To: ThienDuc Nguyen; juniper-nsp@puck.nether.net Subject: Re: [j-nsp] LACP on mixed virtual chassis QFX5100/EX4300 Hi, Am 03.11.2015 um 23:23 schrieb ThienDuc Nguyen: > I was trying to create a LACP bundle between two ports : one on a > EX4300, the other on a QFX5100. > Both link have their speed negotiated at 1GE (but the interface name > on the QFX is xe-, I can't force it to ge-, and their are no way to > force the speed on the QFX). > if I set the lacp speed to 1ge, the configuration can't commit because > it sees the QFX interface as a 10G interface... > > > Is their a special knob to activate it, or I need to create LACP on > the same device family ? (the version is 14.1X53-D30.3) From what you wrote i would suspect that you use a QFX5100 copper version? If they behave anything like the EX45XX Copper Versions the interfaces will always be xe- regardless of them being only used with 1GE neighbors. Would be funny if the interface name would change when lower speeds are negotiated. Probably the config parser checks the physical interfaces and finds out that it is a 10G interface on QFX and 1G Interface on EX and will not commit as mixed speed AEs are only supported in later MX code. I do not know a way around that and do not have copper QFX at hand to check. Probably you will have hit one of these corner case situations that nobody thought about and nobody ever encountered and nobody ever asked about (at least if you ask jtac :)) -- Kind Regards Tobias Heister _______________________________________________ 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
