DXS-3326GSR Gigabit Layer 3 Switch
Unit
The ID number of the Switch in the switch stack that has permanently learned the
MAC address.
Port
The ID number of the port that has permanently learned the MAC address.
Type
The type of MAC address in the forwarding database table. Only entries marked
Secured_Permanent can be deleted.
Delete
Click the
in this field to delete the corresponding MAC address that was
permanently learned by the Switch.
QoS
The DXS-3326GSR supports 802.1p priority queuing Quality of Service. The following section discusses the
implementation of QoS (Quality of Service) and benefits of using 802.1p priority queuing.
Advantages of QoS
QoS is an implementation of the IEEE 802.1p standard that allows network administrators a method of reserving
bandwidth for important functions that require a large bandwidth or have a high priority, such as VoIP (voice-over Internet
Protocol), web browsing applications, file server applications or video conferencing. Not only can a larger bandwidth be
created, but other less critical traffic can be limited, so excessive bandwidth can be saved. The Switch has separate
hardware queues on every physical port to which packets from various applications can be mapped to, and, in turn
prioritized. View the following map to see how the DXS-3326GSR implements 802.1P priority queuing.
