Parameter
inbound:
Limits the inbound packet rate.
outbound:
Limits the outbound packet rate.
target-rate:
Total target rate (in kbps). The range of this argument varies with port type
as follows:
l
Fast Ethernet port: 64 to 99,968;
l
GigabitEthernet port: 64 to 1,000,000.
The granularity of port rate limit is 64
Kbps. Assume that the value you provide for the target-rate argument is
in the range N*64 to (N+1)*64 (N is a natural number), it will be rounded off
to (N+1)*64.
