You can un-install the dude before updating to final v6

Then Update to final v6, and update to latest v7

Hi,

It appears you are correct. Packet capture shows e.g. arp arriving at the AP as broadcasts but at the client as unicasts.

Thank you.

merlinthemagic7

Hi, We use radius to place wireless users in VLANs. Question is: How is broadcast isolation maintained, when there are many different vlans in use on a particular BSSID? Does MT use GTK for encrypting broadcasts? We use "multicast-helper = full", so multicasts are converted to unicast and ...

@dekiel Yes MSTP is an open issue (no specific confirmation on edge propagation).

Here is another post:viewtopic.php?p=948438#p948438

Recommended work around is using RSTP for the time being.

Back to rSTP for awhile

This is the BUG on v6 and on v7 is fixed.

I believe you. Is there any document that talks about this and other changes? Where did you learn that MT considers this a bug to be fixed in V7? Like the title says, im looking for documentation.

merlinthemagic7

The correct behavior is on v7, the local (=discarded later) variables must not be treated as pointer, and updating local variable must not influence global variable, until is not directly wanted. Shared memory is nice, as long as there the proper locks in place. Is there a document i can read that ...

Both work. Can someone share a code snippet where a global array is set, then an index from that array is set in a local and when the index is changed the global reflects this change. /system/script/environment/remove [find where name="TestVar"]; :global TestVar; :if ($TestVar = nil) do={ ...

Hi, See the same thing on 24x CRS328-24P-4S+ running v7.4. Its not just the local MSTP instance that suffers, edge events are propagated downstream as well. Same result except now every edge event results in all switches in the region quitting forwarding for a short while. The downstream propagation...

Hi, See the same thing on CRS328-24P-4S+ running v7.4. Its not just the local MSTP instance that suffers, the events are propagated downstrem as well, but only if the switch has more than one path.

Good tip on readabillity, thx. The idea behind a lib is that each method should abstract from the environment. E.g. like you said, v7 change in syntax, so the factory will check the version of ROS that is running and return an "instance" of the class that works. The method names, parameter...

Even some shorter, since you already are in correct location.

Right on, I always do absolute paths since tracking cwd in scripting introduces another level of complexity.

I would guess it can use all frequency between 4920 and 6100. 5825-5825 is between this number so no extra line is needed. And for 2.4 GHz 2733-2483 can not be used, so therefor two lines.

I might be wrong here, but I believe crypto driver tries to use the same cpu core to process each packet/stream to which it was assigned by ethernet driver.

That is just how IPsec is processed by this driver. It is not feasable to make a single IPsec stream/policy multithreaded as it will introduce latency, packet reordering and other unnecessary issues.
