I have a C4506 as Core switch, copules of C2924 as Distribution switch and dozens of C1924 as access switch. Few of the C1924 are casacaded using F0/27 to F0/26 of another C1924.
I am encountering the following problem:
1) For some of Canon photocopier in the network, I am not able to ping to it from the switches, after I do a "clear mac-address-table dynamic all" on the C4605, these photocopier will response to ping, after certain time (about 1hrs or so). It will not response to ping again. I have to perform the "clear mac" command to get it response to ping again.
2) For some of C1924 that is at the end of "casacade", meaning the second or third C1924 switch that is in the "cascaeded" connection. It will not response to ping from Core switch. It only response to ping after I ping it from the First C1924 on the "cascaeded stack". After certain time (about 1hrs or so), the same problem will come back.
C1924 IOS=Cisco Catalyst 1900/2820 Enterprise Edition Software, Version V9.00.05
I have had a similar problem and found the following solution:
On the 1924 you can configure a network port on A or B port. When this is done, broadcasts are only sent to this port and not flooded. Hence, when ARP times out on an adress it remains dead until it it is pinged again from the switch. The idea with this feature is that the nodes on the switch will only establish outgoing connections.
