Re: RB3011 port flopping - bad design

My RB3011 started flapping on ports 6-10 after a reconfiguration, and I'm running 7.1beta3 . Apparently, OS version doesn't really count anything re. this flapping issue. I really would like to see some extra debugging about the interfaces. I tried to set debug logging but nothing is printed in logs...

Re: separate trunks CSS610 <-> RB3011 weirdness

I have replaced the CSS610 with an RB4011 and the bonding now behaves properly, and speed is proper.
I think the CSS610 is a flawed product and recommend to stay away from it for the time being.

Re: separate trunks CSS610 <-> RB3011 weirdness

it does not run SWOS. it runs "SWOS lite". I am not sure if the limitation is in hardware but seems quite a serious one for a switch considering
that for $40 more you get a full-fledged CSS326 with more ports and more pps

Re: Sierra MC7455 with RouterOS 7.1b3 on RB922UAGS

Your modem should be supported in MBIM mode. But you will not be able to talk to it using at-chat.

Re: AT Commands to modem in MBIM mode?

This lack of at-chat capability is serious because when using such modems there is a lot of tun...

I always have three bands in CA (very good signal).

In your case, it simply disconnect poor connection but you can lock in bands you want as you already did.
Unfortunately it seems I can only lock primary band. I wish I could also lock the CA ones.

I have not had time to confirm this, but your issue may be result of EG12-EA not passing correct APN to provider, even though it is correctly setup in ROS7 beta8

Try setting APN directly on modem via AT command AT+CGDCONT.
