What’s new in 6.41rc3 (2017-Jul-26 09:32): Important note!!! Backup before upgrade! RouterOS (v6.40rc36-rc40 and) v6.41rc1+ 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.

*) bonding - improved relialibility on bonding interface removal;
*) bridge - fixed ARP setting (introduced in v6.40rc36);

*) bridge - implemented dynamic entries for active MST port overrides;
*) bridge - implemented software based “igmp-snooping” (CLI only);

*) bridge - removed “frame-types” and “ingress-filtering” for bridge interfaces (introduced in v6.40rc36);
*) certificate - show “Expired” flag when initial CRL fetch fails;
*) e-mail - do not show errors when sending e-mail from script;
*) firewall - properly remove “address-list” entry after timeout ends;
*) hotspot - improved user statistics collection process;
*) interface - improved interface state change handling when multiple interfaces are affected at the same time;
*) ippool6 - try to assign desired prefix for client if prefix is not being already used;
*) lte - allow to specify the MAC address for passthrough mode;
*) ppp - added client support for Sierra MC7750;
*) rb2011 - fixed possible LCD blinking along with Ethernet LED;
*) rb922 - restored missing wireless interface on some boards;
*) sftp - added functionality which imports “.auto.rsc” file or reboots router on “.auto.npk” upload;
*) trafficgen - fixed “lost-ratio” showing incorrect statistics after multiple sequences;
If you experience version related issues, then please send supout file from your router to support@mikrotik.com. File must be generated while router is not working as suspected or after crash.
I am sitting in my office at work and have just update my RB2011UiAS-RM remotely, after rebooting the router am not able to access my router from the WAN side, my internet service provider is a WISP so I logged into my CPE and tried to SSH my router, I am able to login to the router but as soon as I login, the router stops responding for a few minutes and then comes back, same thing keeps happening when trying to SSH to the router. Will have to check the router when I get home.
Folks, don’t upgrade your router if it is on a remote location
My understanding from the 6.40rc36 and 38 releases was that the switch chip menu was to not be used for ports not in a new bridge and ideally all configurations should move to the new VLAN aware hw-offload bridges.
I do recall a conflicting post from a MikroTik poster so clarification from own of the MikroTik folks would be great.
Upgrade from 6.40 last rc to 6.41.3 my 2011UiAS-2HnD all leds on active interfaces are off, Except led on eth10 is on witch is POE Out and is active. Is this normal or something wrong with this.
Currently, it is implemented only for CRS3xx series switches.
On CRS125 VLANs still have to be configured in “/interface ethernet switch” menu to keep hw-offload working. If they are configured in “/interface bridge vlan”, the hw-offload will turn off.
The VLAN does not work on the Atheros 8327 chip switch.
I create Bridge1 and add Ethernet1 and Ethernet2.
I’m creating VLAN20 on Bridge1 - there’s still ok.
But when I add VLAN20 to Bridge2, RB is unavailable on these two ports.
It does not work even if I put my vlan on ether1 or 2.
I want to get the old way tagged vlan20 on ports ether1,2,3 … n (before master port1 and slave ether2,3, … n)
Bridge strip Taging. I have DHCP server for vlan20.
It works great on chip switch Atheros 8227.
Simplified Example:
State is ‘invalid’
