enable flooding ports
ExtremeWare Software 7.0.0 Command Reference Guide 189
enable flooding ports
enable flooding ports <portlist>
Description
Enables packet flooding on one or more ports.
Syntax Description
Default
Ports are enabled for learning, not flooding.
Usage Guidelines
This command configures the specified ports to act like a hub. When flooding is enabled on a particular
port, all frames and packets are passed on to other member ports that have flooding enabled. This
includes all broadcast, multicast, known unicast and unknown unicast packets (including EPD). To
make effective use of this feature you should have flooding enabled on more than one port.
Learning and flooding are mutually exclusive. To enable flooding, you must first disable learning.
When ports are configured for flooding, the FDB will be flushed for the entire system, which means all
the entries in the dynamic FDB must be relearned.
On a modular switch,
<portlist>
can be a list of slots and ports. On a stand-alone switch,
<portlist>
can be one or more port numbers. For a detailed explanation of port specification, see “Modular Switch
Numerical Ranges” or “Stand-alone Switch Numerical Ranges” in Chapter 1.
Example
The following command enables flooding on ports 6, 7, and 8 on a stand-alone switch:
enable flooding ports 6,7,8
