Greetings,
My organization is pushing new operating systems out over many LANs using
Symantec Ghost. Getting a lot of help calls when the administrators try to
push during production hours, and, most of the time, when they are pushing
this traffic over older 29xx series switches (2900, 2924, 2948, and 2950).
Indications point to the fact that they are just pushing the devices too
hard; I usually check "show proc cpu" to find the CPU is running very high
and "show log" generally displays a lot of collisions, but few, if any,
errors.
I'm using the "show controller switch" command to determine whether or not
the switch is operating at maximum bandwidth capability. The only problem is
that I cannot find a reference for the metrics this is displaying.
"If the Total Allocation reaches or is over the Congestion Threshold amount,
the switch is experiencing considerable network activity near its full
capacity." (see example below) This is all well and fine, and I am
convinced, but I want to have a definition of what these hexidecimal numbers
indicate (i.e. is this some kind of measurement that I can convert when I am
explaining the situation?).
Thanks in advance,
John
