Hello,   I have in my setup 1x M16 and 2x M18 with firmware 26.1.   M16 is loosing regularly connectivity. Event log does not show any error messages. I have no problems with M18 in my setup with same firmware. Static IP is configured on M16/M18 and there is not so much clients and traffic on the box (30Mbits/sec and max 10 clients). This is not a new setup. I am running this setup since a while.   M16 was connected to c3560 with IOS 15.2(2)E6. The switchport is configured as access port: interface GigabitEthernet 0/1  switchport access vlan 10  switchport more access   I have changed the port on the switch and replace cable. Still the same.   Then I changed to ASA5506 v9.9 and connected M16 to L2 ports with BVI config interface BVI100  nameif inside  security-level 100  ip address 192.168.2.1 255.255.255.0 interface gigabitEthernet1/8  bridge-group 100  nameif inside_2  security-level 100   ASA and switch config is just simple and straightforward. I am still seeing the loss of connectivity.   Thanks in advance for any hints and tips.   Best regards, Cengiz ... View more
