[ixpmanager] MX-LAG workaroud

[Mario Klobucar]

Hi Barry

 

Thanks for info, and confirmation that problems is somewhere on our setup.

 

We have switched from Extreme to Arista.

When I look deep in debug of SNMP MAC polling I realise that Extreme in LAG is bonding MAC to Physical ports, and Arista to port channel.

On Extreme things where working even we have didn’t realise meaning of “Bundle Name” on virtual interface.

When we set up “PortChannelyx” as bundle name,  missed MACs are bundled with virtual interfaces and inserted into MAC table.

 

Best

Mario

Hi Mario,

I'm not sure I full understand the issue. While MC-LAG isn't officially supported some IXPs use it and have made it work with IXP Manager.

For p2p graphs, you need to set the MACs in one of two ways as documented here:

https://docs.ixpmanager.org/latest/features/layer2-addresses/

I suspect if you use the 'configured MACs' it will work fine as this attaches the MAC to the vlan interface.

See https://docs.ixpmanager.org/latest/features/sflow-p2p/ for updating ixpmanager.conf on your sflow collector where you'll need to set:

macdbtype = configured

Hi

 

We started to change equipment in one pop in CIX and also change setup from stack to mc-lag.

I didn’t noticed before that we can have problems with that.

 

So far graphing (ports overall ..) is working fine, but ptp graphing is missing because mac is missing.

 

Is there any trick how we can insert mac.

I am seeing in LAG case that I table is inserted mac on “one” interface in LAG.

Like adding someplace static mapping to interface mac.

Or inserting in table 5-6 static bindings ..

Or something else.

 

Thanks in advance

Mario
