Version 6.40rc36 has been released. Important note!!! Backup before upgrade! RouterOS v6.40rc36 contains new bridge implementation that supports hardware offloading (hw-offload).
This update will convert all interface “master-port” configuration into new bridge configuration, and eliminate “master-port” option as such.
Bridge will handle all Layer2 forwarding and the use of switch-chip (hw-offload) will be automatically turned on based on appropriate conditions.
The rest of RouterOS Switch specific configuration remains untouched in usual menus for now.
Please, note that downgrading to previous RouterOS versions will not restore “master-port” configuration, so use backups to restore configuration on downgrade.
Before an upgrade:
Remember to make backup/export files before an upgrade and save them on another storage device;
Make sure the device will not lose power during upgrade process;
Device has enough free storage space for all RouterOS packages to be downloaded.
Changes since previous 6.40rc release:
!) bridge - implemented software based “igmp-snooping” (untested, undocumented, CLI only);
!) bridge - implemented software based MSTP (untested, undocumented, CLI only);
!) bridge - implemented software based vlan-aware bridges;
!) switch - “master-port” conversion into a bridge with hardware offload “hw” option (undocumented, CLI only);
!) switch - CRS3xx switch VLAN configuration integrated within bridge VLAN configuration with hw-offload;
*) filesystem - improved error correcting process on tilera and RB1100Dx4 storage;
*) firewall - fixed bridge “action=log” rules;
*) health - fixed memory leak on devices that have “/system health” menu (introduced in 6.40rc30);

*) ipsec - added support for “key-id” peer identification type;
*) rb3011 - fixed packet passthrough on switch2 while booting;
*) sniffer - do not skip L2 packets when “all” interface mode was used;
*) snmp - fixed “/system resource cpu print oid” menu;
*) switch - fixed “loop-protect” on CRS SFP/SFP+ ports;
*) trafficgen - added “lost-ratio” to statistics;
*) vlan - do not delete existing VLAN interface on “failure: already have such vlan”;

Thank you guys for delivering (actually over-delivering) on your promises! Please take your time to debug 6.40 before releasing it, since it is quite a big upgrade with lots of potential for bugs. And please, create a GUI for the new bridge implementations!
Please note that this is the first release with such functionality and can cause different kinds of issues. Main reason for this release is to allow you to help us debug new implementation and polish it until it will be ready for 6.40 full release.
My WLAN interface IN AP mode just stop forwarding any data (added to a bridge). I can access to my MT by ARP only.
Is something new that I’m missing in configuration?
In the header of the /export to file, there are two extra “comment” lines that are empty but they contain a superfluous CR character.
They show up in my editor like this:
#^M
#^M
(below the software-id)
Edit: the above was on a CHR. When I tried the new RC on a RB750 the above two lines contain the model and serial number, a nice addition,
however there still are those superfluous CR characters…
