Considerations
■
If the limit that you set is reached during a given second of time, all
remaining frames that are received in that remainder of that second
are dropped.
■
A value of zero means that there is no limit set on the port. This is the
default setting for all ports.
■
On Multilayer Switching Modules, the limit always affects both
multicast and broadcast packets. You can set similar limits using
options on the Quality of Service menu.
■
If you want to specify a limit for a trunk, you only need to specify the
trunk’s anchor port (the lowest-numbered port). However, be aware
that the limit operates on each link in the trunk, even though you only
configured it on the anchor port.
■
If you have IP multicast application traffic on your network, be sure
that any limits that you configure do not constrain these traffic flows.
On Layer 2 Switching Modules, if you select the
BcastOnl
y option, IP
multicast traffic is not affected.
