NetStructure™ 480T Routing Switch User Guide
The MAC address options are:
• Permanent
• Dynamic
• Blackhole
• Broadcast/unknown rate limiting
Permanent MAC Addresses
Permanent MAC addresses can be assigned a QoS profile whenever
traffic is destined for the MAC address. You can do this when you
create a permanent FDB entry. For example:
create fdbentry 00:11:22:33:44:55 vlan default port
4 qosprofile qp2
Dynamic MAC Addresses
Dynamic MAC addresses can be assigned a QoS profile whenever
traffic is destined for the MAC address. For any port on which the
specified MAC address is learned in the specified VLAN, the port
is assigned the specified QoS profile. For example:
create fdbentry 00:11:22:33:44:55 vlan default
dynamic qosprofile qp3
The QoS profile is assigned when the MAC address is learned.
When a client location changes, the assigned QoS profile moves
with the device. If the MAC address entry already exists in the FDB,
you can clear the forwarding database so that the QoS profile can be
applied when the entry is added again. The command to clear the
FDB is:
clear fdb
Blackhole MAC Address
Using the blackhole option configures the switch to not forward
any packets to the destination MAC address on any ports for the
VLAN specified. The
blackhole option is configured using this
command:
create fdbentry 00:11:22:33:44:55 vlan default
blackhole
