MX85 Dashboard port numbers, versus eventlog and lldp port numbers ?
So Im trying to troubleshoot some issues on a network with a MX85.
In the eventlog for the MX85 I for example see "device: port3, carrier: false".
Port 3 , on the dashboard UI page of the MX85 is the WAN1 RJ45 port, so this would be "bad".
What boggles me, is that if this Port3 losts its carrier, then it would mean that WAN1 was down, and that I should then see a "Primary uplink status change" in the evenlog as well (since this MX has two running WAN links - not dual active).
But I do not.
I also see one or twice a "device: port4, carrier: false" and that would mean (according to the dashboard UI) that WAN2 would be down ?
(Im not worried at all .... ... .... ).
I then looked at the downlink switch, and on the lldp/cdp neighbour information of this switch it says : Meraki MX85 - fw01 / 6 - but there is nothing connected to Port 6 on the MX85.
(the other downlink switch says : Meraki MX85 - fw01 / 7 for the lldp/cdp neighbour information).
The actual dashboard UI ports are 11 and 12.
So what can I conclude about this ?
Is the eventlog information = the UI truth ?
Or is there an "offset" somewhere, because the lldp/cdp information is clearly not equal to the UI.
AFAIK the WAN port numbering internally is 0 & 1. And the LAN port numbering also starts at 0.
So, for a MX85 the LAN ports from an ifconfig or LLDP perspective would appear as LAN 0-9. Using that numbering your info of physical ports 11 & 12 would equate to the internal numbering scheme mapping to 6 & 7.
