Hi All,
I´m suffering on a WS-C3750X-48 (IOS c3750e-universalk9-mz.122-58.SE2.bin) output drops on an interface.
I think that is due to high load on the interface.
However, this is not my problem, the problem is that the value of output drops makes very rare fluctuations.
Below I paste the command output "show int gi1/0/7" executed two times in the same second:
SW_X_CIC#sh int gi1/0/7
GigabitEthernet1/0/7 is up, line protocol is up (connected)

Anyone suffering this problem?
How can I correct this problem?
Another questions, the value "Total Output drops" from "show int gix/x" is the same as the value "OutDiscards" on the command "show int gix/x counter errors"?
