TheBrothersWISP 19 – US MUM 2014, New Gear, Impressions

So juuuust after the 2014 US MUM, Greg Sowell, Justin Wilson, Mike Hammett, Tom Smyth, JJ Boyd, and special guests Thomas, Wayne, Gabe, Drew, and Brian join us.

Thomas is a genius engineer/instructor from Slovakia who currently works for RF Elements.

The audio is a little wacky since we recorded from Tom’s phone, but hopefully I’ve cleaned it up enough to be tolerable…if not, suffer in silence ;)

Some of the things discussed:
Mimosa gear
CCR 1072
CCR Status Update
New Gear – FTC media converter, New CRS, cAP, mAP
The Dude
NetXMS monitoring system – Latvian monitoring system
CAPsMAN – centralized management
Mikrotik Partitions

Some of the things discussed:
GPON
airFiber/New Ubiquiti Gear
New Mikrotik gear – Thanks for assembling everything Andrew Cox!

MikroTik Scripting: Failover Routing for Asterisk PBX

Hi guys,

This is my second article and I wanted to raise the difficulty level of my tutorials!

We work a lot with Asterisk PBX and MikroTik and we’ve encountered a problem when we have 2 internet connection with a MikroTik using WAN failover, our Asterisk PBX would stop working when the primary connections fail; we finally  figured out why.

In this case, the Asterisk connections would remain appended to the primary gateway, and Asterisk doesn’t understand the change of connection; so we came up with a solution using 2 MikroTik scripts.

First, the “Check Script” checks if the primary internet connection is working or not. If fails, use the secondary internet link and reboot the router. You are probably asking why we would do this…I know!

Because after the reboot I can run a “Restart Script” to check if primary connection is still out, or came back.

In this way, by rebooting the router, the asterisk pbx client loose for a moment the registration and reconnect with the new gateway so everything works.
Actually we’re testing other solutions to avoid the router reboot…when I’ve found that I’ll update this post and let you know!

Editors note: This could be achieved in a few ways, I’ll leave it as a test for our readers to see what improvements you can come up with!

Here are the scripts:

Check Script

:global strDate [/system clock get date]
:global strTime [/system clock get time]
:global strSystemName [/system identity get name]

:if ([/ping 10.104.7.187 interface=pppoe-out1 count=5] = 0 && [/ping 8.8.4.4 interface=pppoe-out1 count=5] = 0 && [/ip route get [find comment="Primary"] disabled]=false) do={
    :log info "Disabling Primary";
    /ip route set [find comment="Primary"] disabled=yes
    /tool e-mail send from="yyyyy@gmail.com" to="xxxx@gmail.com" subject="Route Failover - $strDate $strTime - $strSystemName" body="Failover to Telecom occurred at $strDate $strTime on $strSystemName"
    :delay 3
    /system reboot

} else= {
    :log info "No Failover Necessary";
}

Restart Script

:delay 10;
:if ([/ip route get [find comment="Primary"] disabled]=true) do={
    /interface ethernet set numbers=4 disabled=no

     /ip route set [find comment="Primary"] disabled=no
     /ip route set [find comment="Primary"] distance=3
    :delay 10
    :if ([/ping 10.104.7.187 routing-table=Primary count=5] > 0 && [/ping 8.8.4.4 routing-table=Primary count=5] > 0) do={

       /ip route set [find comment="Primary"] distance=1
       /system reboot
    }
     else= {

        /ip route set [find comment="Primary"] distance=3

    }
} else= {
    :log info "No Failover Necessary";
}

Mikrotik Script: Alert on queue tree limit exceeded

Hi guys,

This is my first post here, I’m a Network Engineer who works a lot with Mikrotik devices and Server Administration and you can see more of my posts on my website. I found this blog some time ago and was invited to contribute with some of my own scripts that may help others!

Today i’ll show you a little script for RouterOS to check if queue tree exceed the limit you set.

For. Example I’ve got a queue tree that limits the amount of total traffic (Upload+Download) to 50Mbps.

I want to know whenever this queue exceed the limit, and I want the system to send me an email.

This is the script:

:global checkrate [/queue tree get total-traffic rate]
:local limit 50000000

:if ( $checkrate < $limit ) do={
:log info ("Queue not Exceeded")
}
:if ( $checkrate > $limit ) do={
:log info ("Queue Exceeded")
/tool e-mail send server=xxx.xxx.xxx.xxx from="me@myself.com" to="me@myself.com" subject=("Queue Limit Exceed") body=("Queue Limit Exceed, Limit is: " . $checkrate)
}
Enjoy!

CRS Basic Vlan Configuration

I’ve been playing around with v6.13rc12 over the last week on a CRS125-24G-1S and have put together a an example script for provisioning the unit with a user-vlan and an admin-vlan that are trunked back via the SFP port.

I’ve been waiting for a long time to have a usable and readable switch chip config on the CRS platform, so I hope this is useful for some of you guys too.
