on cat3750 you can limit the Bandwidth on a n egress interface using the SRRcommand:
srr-queue bandwidth limit "weight1"
the weight1 is a variable in the range from 10 to 100 (default)
This means that in a 3750G a giga interface the egress queue can be limited only to 100Mbit/s (setting the weight1=10)...or the siwtch is able to interpret the weight in correlation of the port settings
for example a gigabit port is connected to a device and the settings are 100FD
if the srr weight1 is set equal to 10 then the egress BW is 100Mbits, seeing it's a giga interface, or 10Mbit/s seeing it's a giga interface BUT connected as 100FD ?
While I am not in a position to log into a 3750 and verify this right now, I am pretty sure that the setting will apply to the speed at which the interface is connected. This is because QoS parameters act on the bandwidth as dislayed by the 'show interface' command. When a Gig interface is connected at 100Mbps,the bandwidth is set to 100000k, and therefore that is what the 'srr-queue bandwidth limit' command should act on.
Hope that helps - pls do rate the post if it does.
