Hi All,
I currently have a Meraki MX64 Firewall that I have uplinked to a Cisco 3750G that has multiple SVI. Everything is working, but I am trying to track down a few odd messages I am seeing in the logs of the Meraki device. I have configured the uplink ports as per Merkai documentation, but Meraki support won't assist further since their device is connected to a Cisco switch so I am hopeful someone here can help me verify I have the correct port configs on my Cisco 3750.
The errors in the Firewall logs are:
Source IP and/or VLAN mismatch - This happens sporadically
DHCP problem - This is happening every 1 minute to the same client device. I tracked it down and the odd thing is the device having this error is configured statically and should not be making DHCP request. I have tried setting this device to accept a DHCP address and it does successfully, but the errors in the log still persist. Making me wonder if I have something on my Cisco switch misconfigured.
3750 holds multiple SVI
Vlan 10 - 10.10.1.0/24
Vlan 20 10.10.2.0 /24
Vlan 30 10.10.3.0/24
Vlan 40 10.10.4.0 /24
Vlan 50 10.10.5 .0/29 *This is where the firewall is.
Gateway of last resort is the IP of the Meraki Firewall 10.10.5.2
The switch default gateway is 10.10.5.2
