java - Netty - Ignore failed setting of IP_TOS -

my users reporting error me, , silently ignore it, since non crucial part of application.

to accomplish this, setting ip_tos alternative in serverbootstrap: childoption(channeloption.ip_tos, 0x18)

if know need place handler, or alternative ignore failure in setting option, please allow me know.

md_5

here's illustration bootstrap code sets option:

bootstrap b = new bootstrap(); b.group(new nioeventloopgroup(), new nioeventloopgroup()) .channel(nioserversocketchannel.class) .option(channeloption.so_backlog, 100) .handler(new logginghandler(loglevel.info)) .childhandler(new channelinitializer<socketchannel>() { @override public void initchannel(socketchannel ch) throws exception { seek { ch.config().settrafficclass(0x18); } grab (channelexception e) { // ignore } ch.pipeline().addlast( new logginghandler(loglevel.info), new echoserverhandler()); } });
