v6.41 [current]

Announcements
1

RouterOS 6.41 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:

  1. Remember to make backup/export files before an upgrade and save them on another storage device;
  2. Make sure the device will not lose power during upgrade process;
  3. Device has enough free storage space for all RouterOS packages to be downloaded.

e-mail - do not show errors when sending e-mail from script;

But still appears in the log, I hope?

3

oh my god. and i was thinking what i am gonna do in christmas (4 days holidays). testing testing testing
nice!

4

macsrwe - Of course. This affects only console so e-mail would work properly in script.

*) crs326 - fixed packet processing speed on switch chip if individual port link speed differs;
*) crs326 - improved transmit performance from SFP+ to Ethernet ports;

Sorry, I can not confirm this. Write performance is 105MByte/s, read performance is about 50MByte/s.
It has increased from former versions which was around 20MByte/s. But still far away from full 1GB/s performance.
Flashing back to SwOS 2.3 gives full performance. SwOS 2.4 puts switch in endless reboot loop.
SwOS 2.5 - 2.6 has the same poor performance of about 20MByte/s. SwOS 2.7 is same as RouterOS 6.41.

Tested with Mellanox and Intel NIC.

6

dksoft - Are you running CRS on SwOS or on RouterOS? If you run RouterOS, are you using device as a switch or you use also router functions, for example, firewall rules?

7

I tried both. RouterOS 6.40 - 6.41, SwOS from 2.3 - 2.7.
Configuration is reset to default after each update. So there are no firewall rules. All ports are switched.

Could somebody tell me how to use vlan in hex v3 properly? By /switch or by /bridge?

Ran into the following bug with upgrading an RB450 from 6.40.4 to 6.41:

NOTE: It appears I must have had the old configuration of ether2 being master and ether3 to ether5 being slaves

  1. I performed the upgrade via the console
  2. When the router rebooted, ether1 was stable, but ether2 to ether5 were flapping at least every second.
  3. I tried power-cycling and same issue as #2
  4. I used my cell phone to login to the router via the Internet and inspected the configuration.
  5. I noticed that the upgrade process had converted the master/slave config to bridge config.
  6. I couldn’t find anything wrong except for the fact that the bridge “protocol-mode” was “none”
  7. I changed “protocol-mode” to “rstp”
  8. Interfaces stabilized and now everything is working.

You may want to update you migration script so “protocol-mode” IS NOT “none”

Thanks

Hello,
thanks for the update. I use RouterOS for years running CAPSMAN forwarding based wifi controller with dynamic VLAN IDs for one SSID sent by Microsoft NPS. Upgrading that config from 6.40.5 to 6.41 stops traffic for my clients. I don´t know the reason yet. I have to setup another CAPSMAN and test it some time in 2018. But that´s not the question for now.

I would like to know whether I should expect problems when I let my CAPSMAN controller stay at 6.40.5 and upgrade all CAPs to 6.41 (because of the new wireless drivers)?

11

Not happy with the conversion…lots of trouble…looking to solve it.

Update:
Despite the promise by support, the bridge was not created and the interfaces (ports) not attached. The DHCP was not moved from previous master to bridge so DHCP. At least it is stable now for a 10 minutes so I can do some more testing and checking.

L2TP+IPSEC with multiple connections is loading up one core and one to 50% and the last two are almost not used.

Update:
It seems to works now as far as I could test it for now and I keep it up and running on 6.41. Thanks for the upgrade and certainly a lot of things are now improved over 6.40.

12

Found a first anomaly:
Neighbor discovery does not work with the generated ‘discover’, ‘mac-winbox’ or ‘mactel’ interface lists. Other lists seem to work.
After list deletion and recreation by hand, it works.

13

Upgrade on RB450G went smoothly. Changes to ethernet removing master-port, interface list adding default lists and then neighbour discovery and mac-server to use the lists.

14

I reset the config on a RB952ui-5ac2nd-us to a default setup on bugfix 6.39.3, and then upgraded it to 6.41. I was connected by mac address in Winbox, not IP. After the upgrade the lights were on but I did not see it in the neighbor list in Winbox. I let it set for about an hour just in case it was still upgrading, but it never showed up. I did not try to connect by default ip 192.168.88.1. Power-cycled it instead, and then it showed up on the Winbox list. So I’m not sure if it was down, or just didn’t show up on the neighbor list initially.

UPDATE: I repeated those steps on a new unit I had in stock and observed the same thing. I did confirm that the router was still accessible by IP address (default 192.168.88.1 in this case), just not MAC address. I rebooted the system from Winbox and then, like before, it showed up by MAC address in the neighbor list.

15

I wonder if there were any changes between 6.41rc66 and 6.41 release to the multicast package or wireless. I’m watching IPTV over a wireless connection using IGMP Proxy and after the upgrade the image keeps freezing (in about 10 mins after a reboot). No changes to the configuration was made, just the upgrade. Reverting to 6.41rc66 fixes the issue.

Update: it seems to be related to the wireless (checked only 5GHz AC, RouterBOARD 962UiGS-5HacT2HnT) cause it works fine over the ethernet cable. looks like some packets are dropped (Tx is ~7.5 Mbps on bridge and ~5.5 Mbps on wlan).

Update 2: I’ve found out that the freezes related to a second device connected to the wireless network (iPhone SE). When the phone goes to the sleep mode, IPTV starts freezing. Awakening the phone stops the freezes. Oddly that stated to happen only after upgrade from 6.41rc66 to 6.41

16

still problems with ingress rate limit on crs326, when set to 135m ingress I get around 100m on speedtest.net, on the 200 pieces of crs226 ingress rate works, when set to 135m I get 130m on speedtest.net

but it has improved since 6.40rc66 where when set to 135m I only got around 30m on speedtest.net

funny enough when I try to change the egress or ingress rate limit now on my test crs326 I get this error

"couldn’t change switch port - vlan mode not supported (6)

so still 6.41 is still buggy, and not ready for use in a normal setup, but hopefully it will soon be ready, because I need to replace 100 x Dlink 48 port switche, with 200 x CRS326 when they are stable and able to work with egress and ingress rate limits and port isolation and port leakage

Have a merry Christmas

17

For the new bridge implementation, I assume this does not affect the wAP ac access points? Or do they have a hardware switch built in?

18

No, there is no switch: https://i.mt.lv/routerboard/files/RBwAPG-5HacT2HnD-161216162504.png

19

Upgraded RB2011, hAP, wAP ac, cAP and a RB1100 without issues. But wondering if there is a new way of how I should handle bonding interfaces with vlans? Currently I have two bonding interfaces with two ethernet ports each. On each of the bonds I have severals vlans and the vlans are put on a separate bridge (one bridge per vlan). Is there a new and perhaps smarter way of doing this now?

20

I upgraded my RB750Gr3 from 6.40.5 to 6.41, and now I cannot connect to it via wire or wireless. Did I miss anything here?

Thanks.
