Who might be able or deny if Meraki MX make a syslog entry when either the DHCP Scope is depleted or when it cannot lease an IP to a client due to lack of available IPs?
I know there is an endpoint that provides this, but at scale it's too expensive to use against the Dashboard API rate limits.
Example API output. Can some provide a related event message example from the syslog?
Thanks so much.
Solved! Go to solution.
I'd assume the "dhcp no offers" syslog event might also trigger. See...
Hi,
Easy to test. Created a /30. Plugged a couple devices and captured the MX screaming these logs :
Done on MX18.107.6
I'd assume the "dhcp no offers" syslog event might also trigger. See...
Thanks. Based on this I found the event.
Also note that the "free count" that the API returns fails to take into account DHCP reservations. So it is very possible to have a "freeCount" and to have no DHCP addresses available.
You can test this easily by creating a DHCP scope, and then reserving the whole thing.
Thanks. This helps me to understand what I might be looking at where I'm seeing "dhcp no offers" in the syslog but the following endpoint shows a freeCount of 29.
https://api.meraki.com/api/v1/devices/[Serial]/appliance/dhcp/subnets
[{"subnet":"10.0.25.0/24","vlanId":0,"usedCount":224,"freeCount":29}]
I'm seeing this "dhcp no offers" event for the same mac address about every minute directly preceded by the following event types:
"wpa_auth" |
"association" |
"disassociation" |
"association" |
"wpa_auth" |
"disassociation" |
