6.10.3 More About Rate Limiting
Rate Limiting enables Service Providers in Multi-Dwelling-Unit (MDU) and similar environments
to offer varied bandwidth to customers using low cost Ethernet connections. Another solution, for
the enterprise, is to provide high priority bandwidth on the network for guaranteed service level
agreements.
NOTE: To remove a mark, perform steps 1 and 2 . When a marked line is highlighted,
pressing M will remove the mark. If all marks are removed, the DEL MARKED command
is changed back to DEL ALL
.
NOTE: When allocating the maximum rate per port, the maximum bandwidth of the
uplink must be kept in mind. For example, if the ports are all set to 10 Mbps and there
are 24 ports, this equals 240 Mbps of bandwidth. If the uplink is only 100 Mbps, there is
an obvious problem if the network administrator guaranteed more bandwidth than the
uplink can support.
