RB2011 not matching packets in dynamic queues
by Paul Julian 19 Jul '14

19 Jul '14

Hi guys, we have a strange issue with an RB2011 which we use as a basic LNS at a small remote site, it has stopped being able to ping the dslam that it connects to although layer 2 still works fine between the two, and whilst the config we have on it is identical to many others we have it refuses to match packets in dynamic queues which are created for the PPPOE connections which terminate on it. Even when creating simple queues manually for the PPPOE interfaces no packets get matched. I upgraded it to 6.15 initially and thought that was the issue, so I have now downgraded it to 6.11 but the problem persists. I am perplexed by this one, we have the same config running at a lot of locations and don't have issues, even with 6.15, and it's not the sort of thing I would have thought would be hardware related. Has anybody experienced this type of issue at all ? I know the next step is probably to netinstall it but as it's a production site it's hard to do rebuild like that due to downtime so I might just build up a new router and send it out as it will be a quick replacement. Any thoughts would be appreciated. Thanks Paul

routerOS 6.16 released
by Mike Everest 18 Jul '14

18 Jul '14

Hi All, Noticed this in the changelog for 6.16: *) CCR - fixed rare file system corruption when none of configuration could be changed or some of it disappeared; something that has been experienced by at least 4 users that I am aware of (new users vanish after adding, can't write to filesystem, etc) - so it wasn't just our imagination after all ;-) Cheers, Mike.

/31 and /32 subnets
by Paul Julian 15 Jul '14

15 Jul '14

Hi guys, we are looking at ways to redesign our network a bit to be more lean on IPV4 usage as I'm sure a lot of people are probably doing, between all of our POPS and within our core network we have /30's in use as I suppose most people do, however we are starting to run low on IP's and rather than request another allocation which we could easily justify I would rather try and tidy up our network to be more efficient. I was wondering what people's experience has been with Mikrotik using /31 subnets and /32 addresses with the remote end address as the network address ? We mostly run OSPF for our network routing with some BGP on the edge routers, does anybody have any comments on things to be aware of ? Regards Paul

Hi guys, I'm not sure if this is an inappropriate post but I urgently need somebody to do some onsite IT support for a customer in Lilydale in Victoria, is anybody able to provide a decent onsite resource to do some troubleshooting for us on a local network with a couple of PC's and ADSL connection ? If so please reply privately with your rates and availability Thanks Paul

WDS disconnects
by Matt Chipman 14 Jul '14

14 Jul '14

Hi all, does anyone have any issues with WDS? We have a single RB951G-2HnD connected via ethernet cable to a snapgear which supplies internet. Connected to the 951 are "7" RB9512n via WDS in a rectangular shape (office space) to cover all the users. This is essentially a guest network and works well most of the time. The problem we have is each device will drop off once in a while and cause outages for the users connected to that device and it either wont reconnect within a reasonable time or will need to be rebooted. On each router, a bridge is configured and then WDS selected on it. Each wifi signal can connect to at least 2 others so the mesh topology works but I want to get the stability up for the users. Its not the same device that loses connectivity, its rather random. any pointers greatly appreciated. cheers -Matt

VLAN MAC Address Problem
by Paul Julian 14 Jul '14

14 Jul '14

Hi guys, I am hoping somebody might have come across this problem before. We have a customer Mikrotik CCR which runs just over 1000 vlans, pretty much all are QinQ, so we have a couple of parent VLANS with the rest hanging off those, some parents have a couple of hundred vlans hanging off them each. Everything is working fine except one strange thing. On one of the inner VLAN's when it's created it doesn't inherit the MAC address of its parent physical interface, the MAC just stays blank. I have recreated the VLAN from scratch, tried changing the VLAN ID, the name of the VLAN interface, etc but nothing I do gets a MAC address in there unless I assign it to a different physical interface. The particular VLAN which is the outer tag has about 220 VLANS hanging off it, all of which are working fine except this one. Has anybody come across this at all ? The router is running V6.10, I would update but there is a change freeze on so not really possible at the moment.... Thanks Paul

Hi everyone I'd hoped Google could answer this, but apparently not. Does anyone know which UDP port(s) CAPsMAN uses for provisioning over IP? Thanks Russell Hurren Managing Director Zero Point Networks PTY LTD +61 8 6262 9376

CAPSMan
by Paul Julian 02 Jul '14

02 Jul '14

Hi guys, I was wondering who has done some playing around with CAPSMan so far ?? We have a wireless network we need to build for a customer but they need a couple of AP's on the same SSID in reasonably close proximity which means they will interfere with each other. I was wondering, with the limited amount I have researched this new component, will it help in this situation and allow users to smoothly transition from one AP to another ? Previously we have worked with Ruckess wireless AP's and controllers and they seem to handle having AP's close to each other without any issues for users roaming, will CAPSMan help in situations like this as well ? What approach would you take in this situation ? Thanks Paul

RBMetal2SHPn wireless thermal shutdown?
by Steve at Digitronics 19 Jun '14

19 Jun '14

Can anyone tell me if there is a thermal shutdown arrangement within the wireless component of a RBMetal2SHPn? I have a pair of RBMetal2SHPns on a 13km link and if I turn up the power to get good throughput, the RBMetal2SHPn sending the data shuts down its wireless after some minutes of maximum throughput. The wlan interface still shows as up, but snooping from the shut down end reveals no stations where it normally shows many. It requires a reboot to get it going again. It feels like a thermal issue, but the system temperature does not change, and its cold outside . Any help appreciated. Steve.
