enable flooding ports
ExtremeWare 7.7 Command Reference Guide 311
enable flooding ports
enable flooding ports <portlist>
Description
Enables packet flooding on one or more ports.
NOTE
This command is available only on the “i” series switches.
Syntax Description
Default
Ports are enabled for both learning and flooding by default.
Usage Guidelines
When flooding is enabled on a particular port, all broadcast, multicast, and unknown unicast packets
are forwarded.
When ports are configured for flooding, the FDB will be flushed for the entire system; therefore, 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
History
This command was first available in ExtremeWare 6.2.1.
This command was modified in ExtremeWare 7.3.3b4 to make learning and flooding independent. In
releases earlier than ExtremeWare 7.3.3b4, learning and flooding are mutually exclusive, and to enable
flooding you must disable learning.
Platform Availability
This command is available only on “ i” series platforms.
portlist Specifies one or more ports or slots and ports. On a modular switch, can be a list of slots and ports.
On a stand-alone switch, can be one or more port numbers. May be in the form 1, 2, 3-5, 2:*, 2:5,
