Other VLAN features
11
By default, the device performs
hardware
flooding for Layer 2 multicast and broadcast packets.
(Layer 2 multicast packets have a multicast address in the destination MAC address field.)
However, if uplink VLANs or protocol-based VLANs are configured, this default behavior is
overridden and
software
flooding is enabled.
You can disable hardware flooding for Layer 2 multicast and broadcast packets on a per-VLAN
basis. For example:
BigIron RX
(config)#
BigIron RX
(config)# vlan 2
BigIron RX
(config-vlan-2)# no multicast-flooding
Syntax: [no] multicast-flooding
NOTES:
•
This feature is supported on the 10 Gigabit Ethernet module.
•
This feature cannot be enabled on an empty VLAN; the VLAN must already have ports
assigned to it prior to enabling this feature.
•
This feature is not supported on Layer 3 protocol-based VLANs.
•
This feature is not supported on private VLANs.
•
You cannot enable this feature on the designated management VLAN for the device.
•
If you enable this feature on a VLAN that includes a trunk group, hardware flooding for
Layer 2 multicast and broadcast packets occurs only on the trunk group’s primary
port. Multicast and broadcast traffic for the other ports in the trunk group is handled
by software.
Unknown unicast flooding on VLAN ports
Unknown unicast packets do not have a specific (or unicast) recipient. In order for these "special"
packets to reach their intended recipient, they needed to be sent on all ports of the VLAN (or
"flooded" across the VLAN).
By default, the device performs
hardware
flooding for unknown unicast packets. However, if uplink
VLANs or protocol-based VLANs are configured, this default behavior is overridden and
software
flooding is enabled.
To disable unicast hardware flooding on a VLAN ports and enable software flooding, enter
commands such as the following.
BigIron RX
(config)# vlan 2
BigIron RX
(config-vlan-2)# no unknown-unicast-flooding
BigIron RX
(config-vlan-2)# exit
BigIron RX
(config)# reload
Syntax: [no] unknown-unicast-flooding
