HI!
Very recently I began seeing a lot of Source IP and/or VLAN mismatch entries related to when devices such as computers and VoIP phones are plugged into the LAN. When that happens, the device cannot connect to the LAN and cannot access the Internet.
We have a MX-100 and 4 HP layer-3 switches, and MR-16 APs.
The MX-100 is configured with 3 VLANS 20, 26, 121. Two HP switches are daisy-chained to port 3 on the MX, which is set to VLAN 20. The other two HP switches are daisy-chained to port 7 on the MX, which is set to VLAN 26. The third VLAN is currently inactive.
There is not a physical connection between the two sets of switches and I don't allow any other VLAN traffic on those ports.
Network jacks are duplex jacks...one is for VLAN 20 and the other for VLAN 26.
This issue just started out of the blue even though this configuration has been in place for months. Also the LAN performance has become terrible.
Any thoughts?
