Have a number of 3548's. In the last 3 Months have had up to 8 of them stop responding to Ping. All LAyer 2 Functions and device connected to the 3548 still work.
The Managment address is default Vlan 1, no other Vlans on the Box. No corolation to Uptime, traffic ect.
Concord reports show no Memory,cpu issues before the Devices stop responding to Ping.
Anyone any Ideas. Could SNMP Querys to the Box's be the Problem or a Cause.
