The different cases are handled here: http://elixir.free-electrons.com/linux/v4.11.5/source/net/bridge/br_input.c#L275 fwd_mask_required is not tunable by the user. Unless you are using VLAN-aware bridges _and_ QinQ, its value is 0. group_fwd_mask is the live value you put in sysfs, so it should work. There is a safeguard mechanism to deny acceptance of 01-80-C2-00-00-[00,0B,0C,0D,0F] when setting the group_fwd_mask value. I didn't test recently, but I have used this mechanism in the past for LLDP. Which kernel are you using? -- 10.0 times 0.1 is hardly ever 1.0. - The Elements of Programming Style (Kernighan & Plauger) _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
