Command Syntax
device-name
(config-if

}
Argument Description
enable
Enables flow control on the configured interface.
disable
Disables flow control on the configured interface.
Setting the Default VLAN
The
default vlan
command, in Interface Configuration mode, changes the Port VLAN ID (PVID)
of the configured interface. It is used as VLAN ID for received packets without specified 802.1Q
VLAN tag (untagged packets). The
no
form of this command changes the default VLAN of the
interface to VLAN 1.
To view the default VLAN configuration, use the
show interface
command or
show interface
UU/SS/PP
command in Privileged (Enable) or in Interface Configuration mode.
The PVID of the interface can also be set by the
add ports default
command in Specific VLAN
Configuration mode. For more information regarding the VLAN commands see chapter
“
Configuring VLANs
”.
By default, the PVID is VLAN 1.
NOTE
The user can also change the default VLAN of an interface by using the
add ports
default
command in Specific VLAN Configuration mode.

default vlan
Argument Description
vlan-id
The default VLAN (PVID) for the specified interface. The range is <1-4093>.
By default, the default VLAN (PVID) for all the interfaces is 1.
Setting a Rate Limit on Broadcast Packets
The
broadcast-limit
command, in Interface Configuration mode, sets a limit to the broadcast rate
on the configured interface. The
no
form of the command disables the broadcast rate limit.
This feature allows the user to protect the device against massive reception of broadcast packets
that can interrupt the operation of the device and the network.
The Periodic Monitoring feature allows the user to monitor the incoming broadcast packets on each
interface. For more information please refer to chapter “
Troubleshooting and Monitoring”.
To view the broadcast rate limit status, use the
show interface
command in Privileged (Enable)
mode, with the interface argument specified.
By default, the broadcast rate is unlimited.
