CRS Documentation

Hi MT,

I’ve ordered a CRS for testing. I need much more info to get running with this device.
I see a lot of options in Winbox which are described nowhere.

Could you clarify which options are not documented yet?

Here is the CRS examples page http://wiki.mikrotik.com/wiki/Manual:CRS_examples

Starting with Switch Generic:

Bridge Type
MAC Level Isolation
VLAN Level Isolation
Use SVID in 1:1 VLAN Lookup
Use CVID in 1:1 VLAB Lookup
IPv4 Multicast Lookup Mode
Unicast FDB Timeout


Then there are Tabs “VLAN”, “Exceptions”,“Mirror”

Examples are nice but I need some sort of Manual which describes all of the Parameters/Options.

I have to admit that after upgrading CRS125 to ROS 6.6, the switch configuration in winbox is rather confusing.

What does “Bridge Type” = “service / customer vlan bridge” do?

+1… A manual describing the settings would be great.

+1!

Hello Folks!

Device here is supposed to be a pure managed layer 2 switch for gigabit traffic using one trunk link and access ports connected to vlans, but the device is leaking traffic between vlans and trunk or both.

We urgently need help get it sorted out, we have another tread here, what we have done and so on, we tried all, eithe rthe device does not pass traffic at all or fully locks up so a power cycle is needed or it start leaking:

Here is a tcpdump, this traffic on a fully different vlan100 seen on the access ports of vlan200, I dont know what to do:

Please help!

I have dropped a supout file to MT for help…

@steen

Ask for access to latest beta release.

Draft changelog says:
*) fixed port isolation on CRSs (bug introduced in v6.6);

While port isolation != VLAN leakage it could be how they are describing it.

Hello Alexander!

I got from mikrotik support that RoS6.8 release candidate has that issue fixed. Also I got copy of image from them.
A full reconfigure is needed after RoS6.8 release candidate is installed.
I have not yet tried it, but I will not put something into production with release candidates, it must be stable release.

Hi Alexander,

I popped that release on a CRS and it looks like Pacific/Auckland time now says GMT-7 instead of GMT + 13 :slight_smile:

I understand your position of not putting release candidates into production.

I had a laugh however as I am logged into an edge router I have in the field running 6.6RC1 which if we remember worked however the released version had that VLAN bug.

I am running 6.8 in some secondary devices at the moment to give them some real traffic.

I didn’t know about the full reconfigure being required as I havent tried 6.8 on any of my CRS’s yet so thanks for the heads up

Note to Mikrotik: this may do to be noted on the beta release page.

I more pointed you in the direction of that beta release to test on your spare CRS in the lab trying to generate the bug.

Regards
Alexander

@scampbell

Good of Mikrotik to “fix” our timezone along with all the others.

I can confirm the time in Auckland now is 7:11 pm yesterday (I should look at getting ready for bed soon)

Not sure how Mikrotik stores and updates TZData however it looks like someone accidentially blasted a bad database into it.

Regards
Alexander

6.8rc next release will fix the timezones. there was a bug where all timezones got shifted

Any sign of cli documentation yet ?

any news?

where is promised documentation, without it crs is useless, and previous link with crs_examples needs to be updated as syntax has changed

Please MikroTik team, post documentation of CRS125! We have 20 new switchs here, we need to put up VLAN everywhere, and the examples in the page http://wiki.mikrotik.com/wiki/Manual:CRS_examples don’t work with 6.7 version.

CRS125 seems to be a great product, but how could we use it?

Thanks for your help.

Vincent Florin.

This is absolutely needed.

MT support - Can you promise something?
