Hi ,
I have an asa firewall when i keep in the network it works fine but after 1 or 2 hrs we will not able to reach the firewall all the traffic will be blocked
As i checked i could find the crc errors in the inside interface then i have changed the duplex and speed to auto what could be reason for this issue
below is the interafce details
5 minute drop rate, 0 pkts/sec
Interface GigabitEthernet0/1 "inside", is up, line protocol is up
