addresses to a VLAN so that the address does not get registered outside the VLAN.
If an allowed MAC setting conflicts with a dynamic MAC setting, the allowed MAC
setting takes precedence.
• Storm control causes a switch to monitor traffic levels and take a specified action
when a specified traffic level—called the storm control level—is exceeded, thus
preventing packets from proliferating and degrading service. You can configure switches
to drop broadcast and unknown unicast packets, shut down interfaces, or temporarily
disable interfaces when the storm control level is exceeded.
Understanding Port Mirroring on the QFabric System
Supported Platforms
QFabric System
Port mirroring copies unicast packets entering or exiting a port or entering a VLAN and
sends the copies to a local interface for monitoring. Use port mirroring to send traffic to
applications that analyze traffic for purposes such as monitoring compliance, enforcing
policies, detecting intrusions, monitoring and predicting traffic patterns, correlating events,
and so on.
Understanding Fibre Channel Fabrics on the QFabric System
Supported Platforms QFabric System
A Fibre Channel (FC) fabric on a QFabric system is a construct that you configure on a
QFX3500 Node device when the Node device is in FCoE-FC gateway mode. The FC fabric
on a QFabric Node device is not the same as an FC fabric on a storage area network
(SAN). The FC fabric on a QFabric Node device is local to that particular node device.
We call the FC fabric on a QFabric Node device a
local FC fabric to differentiate it from
an FC fabric on the SAN.
NOTE: The QFX3600 Node device does not support FC or FCoE features.
A local FC fabric does not span Node devices and does not span the fabric Interconnect
device. Local FC fabrics are entirely contained on a single Node device. A local FC fabric
creates associations that connect FCoE devices that have converged network adapters
(CNAs) on the Ethernet network to an FC switch or FCoE forwarder (FCF) on the FC
network. A local FC fabric consists of:
•
A unique fabric name.
•
A unique fabric ID.
• One or more FCoE VLAN interfaces that include one or more 10-Gigabit Ethernet
interfaces connected to FCoE devices. The FCoE VLANs transport traffic between the
FCoE servers and the FCoE-FC gateway. Each FCoE VLAN must carry only FCoE traffic.
You cannot mix FCoE traffic and standard Ethernet traffic on the same VLAN.
