CONFIG: IP  IP Setup  QoS (Quality of Service)
Chapter 20. QUALITY OF SERVICE (QoS)
QoS functionality is dependent on whether the optional IP Packet Processor card is either a) not
installed or installed but disabled, or b) installed and enabled.
QoS Mode: L2 QoS L3 QoS
()
Use the ◄ ► arrow keys to select the basic QoS setup as L2 QoS or L3 QoS:
• Select L2 QoS (Layer 2) when the optional IP Packet Processor card is either not installed or
installed but disabled.
• Select L3 QoS (Layer 3) when the optional IP Packet Processor card is installed and enabled.
L3 QoS is required to support IP Packet Processor Managed Switch Mode.
Press ENTER to continue.
CONFIG: IP  IP Setup  QoS L2 QoS
L2 QoS=Off (Off,VLAN,PT,VLAN&Port)
()
Use the ▲▼ arrow keys to set the L2 QoS operational priority, and press ENTER when done. The
choices are as follows:
Selection Function
Off QoS disabled.
VLAN
(VLAN Priority only) QoS traffic prioritization is applied based on the priority bits in the LAN
ingress packet’s VLAN tag.
PT (Port Priority only) QoS traffic prioritization is applied based on LAN ingress traffic port.
VLAN&Port
(VLAN and Port Priority) In this mode, if the LAN ingress packet contains a V LAN tag, it will
then apply the VLAN Priority scheme; otherwise it applies the port-based priority scheme.
When selecting Port (only) or VLAN&Port, the display updates to include Port Priority on the
bottom line:
L2 QoS=Port only (Off,VLAN,PT,VLAN&Port)
Port Priority: P1:1 P2:2 P3:1 P4:1 ()
To define Port Priority, use the ◄ ► arrow keys to select the port (P1, P2, P3, or P4), and then
use the ▲▼ arrow keys to designate a priority from 1 to 4 (with Priority 4 being the highest).
