iSCSI Optimization
iSCSI is a communication protocol used for sending data between file servers and storage disks. The file
servers are called initiators and the disks are called targets. You can optimize iSCSI flow by setting Quality
of Service frame priority parameters in the device. The device can also intercept iSCSI frames and provide
information about iSCSI communications (called sessions).
For more information, see "Optimizing iSCSI" on page 207.
Voice VLAN
Voice VLAN allows network administrators to enhance VoIP service by configuring ports to carry IP voice
traffic from IP phones on a specific VLAN. VoIP traffic has a preconfigured OUI prefix in the source MAC
address. Network Administrators can configure VLANs from which voice IP traffic is forwarded. Non-VoIP
traffic is dropped from the Voice VLAN in auto Voice VLAN secure mode. Voice VLAN also provides QoS
to VoIP, ensuring that the quality of voice does not deteriorate if the IP traffic is received unevenly.
For more information, see "Configuring Voice VLANs" on page 316.
Guest VLAN
Guest VLAN provides limited network access to unauthorized ports. If a port is denied network access via
port-based authorization, but the Guest VLAN is enabled, the port receives limited network access.

MAC Address Supported Features

MAC Address Capacity Support
The device supports up to eight thousand MAC addresses. The device reserves specific MAC addresses for
system use.
Self-Learning MAC Addresses
The device enables automatic MAC address learning from incoming packets. The MAC addresses are stored
in the Bridging Table.
Automatic Aging for MAC Addresses
MAC addresses from which no traffic is received for a given period are aged out. This prevents the Bridging
Table from overflowing.
For more information on configuring the MAC Address Age Out Time, see "Configuring Address Tables"
on page 267.
Static MAC Entries
User defined static MAC entries are stored in the Bridging Table.
For more information, see "Configuring Address Tables" on page 267.
