Comment 1 Bill Nottingham 2010-06-01 21:44:41 UTC
What are the benefits of enabling or disabling this? Does having it on by default help/hurt?

Comment 2 Tomasz Kepczynski 2010-06-02 05:07:20 UTC
GVRP is a protocol which allows switches to learn about vlan available over trunk ports. The vlans are created automatically and this allows to cut traffic on a trunk port to only that needed.
"gvrp on" will allow linux kernel to announce vlan creation/removal to switch.
I wouldn't put it on by default as: it requires switch with gvrp support; it requires switch to be configured properly. If it is not done then you pay for a feature which is useless for you in terms of kernel time needed to repeatedly send announcements and in traffic itself.

Sorry about the delay. Added in http://git.fedorahosted.org/git/?p=initscripts.git;a=commitdiff;h=f662d4777625cd3bedea19cccabea7741a8b45c9.

Given that none of the other networking keys accept mixed case, I simplified that bit.
