Re: [Mikrotik] FCS errors

[Terri Kelley]

Forgot to report back on this. Mikrotik said grounding was an issue but that 
wasn’t it. I have found that it was 750GLs that did it. The r3’s don’t so I 
just replaced the older ones.

No, that default config was removed.

Hi Terri

How recent a version is running on these? Mikrotik did have some reported
issues in the forums with false readings of loops in some ROS versions.

Also, are these ports the master port for switch groups? I haven't
specifically checked these stats to see if they have devolved them down to
individual ports or if they stay with the master port.

[Mikrotik] FCS errors

[Terri Kelley]

Anyone Monitoring these on 750’s? I’ll have no errors for some time then all of 
a sudden in one poll (snmp) I will have 1 along with all the other errors 
in that interface. And… it will even happen on an interface that has nothing 
plugged into it. Opening the log and I will see;
ether2 excessive or late collision, link duplex mismatch?
ether2 excessive broadcasts/multicasts, probably a loop

But again nothing on duplex going out etc on the log nor link changes i.e. 
speed. And it not only happens on interfaces that have something but those that 
do not. These happen on OSPF and static routing routers so not related to 
either of those items. Doesn’t happen to all of the ones I have and all are 
running recent 6.x OS versions.

[Mikrotik] FCS errors

[Terri Kelley]

Anyone know of a way to check FCS errors via snmp? I see the cli for it and in 
the gui but can't find an oid to pull it. Want to do that so I can graph and 
alarm it from my network monitor. Sometimes I get these when hardware or cat5 
is going south.

In version 6.x you can set the auto-negotiation advertisement rate.
I've got a link that needed it.

/interface ethernet set 0 auto-negotiation=yes advertise=1000M-full

Re: [Mikrotik] FCS errors

[Terri Kelley]

Yeah, have replaced cables, switches and 750s and swapped ends with the 750 
with no help there. Like you I have seen marginal cables or cat5 surge 
protection cause FCS errors. Will take a look at the 2011 which might be good 
since I am running OSPF on one end.

Can't remember what the model of the converters, will have to take a look. Its 
an hour from here so may run over there but they weren't expensive.

By the way Alexander (and others), talked with Time Warner/Cogent today and 
they configure with /24 possible so you can do load balancing. Going to try the 
/22 out to them and maybe some adjusts to get it just right but should do the 
trick. Thanks for the input there.

Re: [Mikrotik] FCS errors

[Alexander Neilson]

You can bridge the ports as normal, however the SFP port on the 2011 is part of 
the same switch group as the 5 gig ports so you can have line speed switching 
just like media converters do it.

 The link between the 750GL goes to a media converter to fiber back to 
 media converter to an HP switch. I've tried moving the 750 from one end to 
 the other of the fiber with the same results. It will occasionally show 
 that the link dies but comes right back up. So I'm thinking it doesn't 
 like the auto detect from the 750 to the media converters and those are 
 not programable.
 So I guess my question is do y'all have suggestions either for better 
 media converters that I can set rate and duplex or perhaps switches with 
 fiber modules that I can set that on the ether side?
 Other ideas?

Re: [Mikrotik] FCS errors

[Terri Kelley]

Ok so that switch group will work on one end and the other I can replace the 
750GL/ospf with a second one. Suggestion on reliable modules y'all have used in 
that port?

Thanks

For fibre? I just use the mikrotik SFP’s, much cheaper than other peoples ones 
and haven’t yet had a laser failure.
