VLAN Injection.....
by Paul Julian 28 Aug '14

28 Aug '14

Hi guys, hoping somebody could suggest an option here. We have a customer that we are doing a trunk for which goes from their office to our DC and then to them in that DC. It looks like: Local Site Data Centre Ether1 -> bridge -> EOIP Tunnel -> bridge ->Ether1 This has been setup this way so that they can just push whatever they want through the tunnel, which is basically 4 vlans, so with this design they should be able to send and receive tagged traffic between the two Ethernet ports without an issue. The problem we have is that we now need to supply an additional vlan to the DC end of the link, but because it's a layer 2 trunk I am not sure of the best way to approach this. I have thought of putting a vlan on the physical interface and another on the bridge interface and setting up a /30 between those two vlan interfaces but to be honest I don't know if that will actually work, has anybody experienced this before and have any suggestions before I just try it ? Basically we need to provide them a layer 3 connection as well as the layer two connection but into the same physical interface at the DC. Thanks Paul

Interception on Mikrotik
by Paul Julian 28 Aug '14

28 Aug '14

Hi guys, we were recently granted a carrier license for another business and we are using a lot of Mikrotik equipment in that business for LNS's and wireless links etc, I was just wondering what method people used on a Mikrotik to satisfy the interception capability requirements and if anybody had any comments on which options were better than others. Most people seem to intercept at the exit of their network, however in our case it's not that simple and we will probably need to provide interception points at each LNS and we have quite a few....so I am interested in what people's thoughts are on the options in this case. Regards Paul

SMS send timeouts
by Thomas Jackson 28 Aug '14

28 Aug '14

Hi all, I'm trying to set up a Nagios box to send SMS alerts using an RB751U-2HnD which has a Telstra 4G USB device (Sierra Wireless 320U) connected to the USB port. At the moment, we use the SMSGlobal API (which was down for most of yesterday afternoon) to send notifications from Nagios, which has the major downside of relying on the internet connection from our Nagios box being alive and of course, relies on the API provider being online as well. The RB751U-2HnD is already in place (it is currently used to provide OOB access into the network - permanently connected to the telstra.extranet APN for a public IP with DynDNS set up so that it can be found), so I figured it would be easy to add this functionality in. So far, I've got a PHP script written that will (via a Mikrotik API call) send an SMS out about 60% of the time - the rest of the time, the API returns a timeout error (also logged to the Mikrotik log - eg "gsm,error sms send failed: timeout"). This happens completely randomly, sometimes I can send 10 messages in a row without a problem, then have another 10 that fail - other times, I can send 10 messages and have every second one fail. A basic solution would be to simply catch the error in the PHP script and try to send again, but I'd like to see if I am missing anything in the Mikrotik config first. Currently running version 6.10 and I can't see anything in the changelog since then that references SMS. Relevant config sections: /tool sms set channel=2 port=usb1 receive-enabled=yes secret=smspassword /port set 0 name=usb1 /port firmware set ignore-directip-modem=yes /interface ppp-client info 0 modem-status: call in progress pin-status: no password required functionality: full manufacturer: Sierra Wireless, Incorporated model: AirCard 320U revision: X1_2_2_0AP R2839 CNSZXD00000128 2011/08/05 15:52:41 serial-number: redacted current-operator: Telstra (cellid redacted) access-technology: Evolved 3G (LTE) signal-strengh: -85 dBm frame-error-rate: n/a Has anyone come against this problem before? Cheers, Thomas

IP Traffic Flow
by Daniel Hoffman 19 Aug '14

19 Aug '14

Hi All. I have a number of CCR1016's in my network, they are all doing TrafficFlow fine, various versions of code base, no issues. I have 1 x CCR1036-8G-2S+ and when I configure Traffic Flow, I see the finished flows, but never see any packets on the collector, a torch on the interface they are coming out and I swear I am not even seeing them there. I upgraded the 1036 to 6.18 and same issue. Anyone else seen anything like it? Daniel

NBN Traffic Management
by Paul Julian 18 Aug '14

18 Aug '14

Hi guys, is anybody successfully doing CVC traffic shaping at the head end for NBN services ?? Having a hard time getting traffic to match the CVC's for outgoing management, it should be working with just the mangle rule on the postrouting chain using the CVC vlan as the interface I would have thought, but I can't get any packets to match the sucker ! I'm wondering if it might have something to do with the bonding setup for LACP and whether I have to enable the firewall for vlans in the bridge firewall settings. Any thoughts ? Regards Paul

the elusive mAP is apparently imminent release ;)
by Mike Everest 12 Aug '14

12 Aug '14

For those who missed it, MikroTik recently announced that mAP was on offer (free) for the next 50 registered attendees at the USA MUM to be held in Pittsburg on September 11 (only a non-US company would pitch an event on that date?) Although official distributors still have no information about this product despite VERY significant market interest, the fact that they are on offer to MUM attendees in September are a somewhat encouraging sign that they may well become available very soon - and that at least, perhaps, they actually DO exist! :-D Maybe we will know what price sometime soon too ;) Cheers! Mike.

MikroTik troubles...
by Mike Everest 11 Aug '14

MikroTik account site offline, emails bouncing. Ouch - I wonder if they applied the latest 6.19 update to their own routers? Regards, Mike Everest www.duxtel.com.au

RouterOS 6.19 - could it be the solution CCR users have been waiting for?
by Mike Everest 11 Aug '14

11 Aug '14

In case you missed it, latest version of 6.19 includes fixes explicitly designed to address general queue problems with CCR models: NOTE: in this build we applied a patch that should solve most of the queueing related performance issues on CCR. If these changes will provide positive feedback we will consider to put them into release of 6.19. Please, test queues on CCR and report results and any problems you might find. It also brings improvements for long term stability of the CCR. They consider this a very important update, and so are also seeking feedback where possible - good AND bad! ;-) Cheers, Mike.

Re: [MT-AU Public] RBMetal2SHPn wireless thermal shutdown?
by Steve at Digitronics 06 Aug '14

It looks like this issue has been solved with a RBMetal2SHPn firmware update. Since the update was applied the problem has not reappeared, even under stress testing. It took a while but this looks like a positive outcome.
