Quality of Service (QoS) ensures better service to high-priority types of network traffic,
which may involve demanding, real-time applications, such as videoconferencing.
| QoS (Quality of Service) |
Application-based QoS manages information as it is transmitted and received.
To use QoS, select Enabled. Otherwise, keep the default, Disabled.
|
| Default QoS Index |
Select the default queue (and priority) for applications not specified below: 1-7 (lower value queue has higher priority).
|
| Summary |
The QoS priorities are displayed with the following information: Port, Filters/Target, Priority, Marks and Action. To opereate on a rule, select the entry (its color will change) first.
To move a QoS rule up in precedence, click Move Up, to move a QoS rule to highest in precedence, click Move Top, to move a QoS rule down in precedence, click Move Down, to move a QoS rule lowest in precedence, click Move Bottom, to delete a QoS rule, click Delete, to edit a QoS rule, click Edit, to create a new QoS rule, click New Rule.
|
Following fields are configured inside New Rule or Edit Rule screen, all values are optional (they can be empty). Note that QoS rules only apply from LAN to WAN.
Click the Add Rule button to add new QoS rule orCancel Changes button to cancel and go back to QoS screen.
|
| Enable |
If this rule is enabled or not.
|
| Classification Sources |
Select All Sources, Local Gateway or All LAN Ports that traffic will come from (default) or a specific LAN port: Ethernet Port 1-5 or WLAN SSID networks.
|
| Ethernet Type |
Select: None, IP (0x0800), ARP (0x0806), PPPoE Discovery Stage (0x8863), PPPoE Session State (0x8864) and EAPOL (0x888e).
Some Ethernet Type will turn on or off following fields.
|
| Protocol |
Enabled only if Ethernet Type IP (0x0800) is selecgted. Select: None, ICMP (1), IGMP (2), TCP (6) and UDP (17).
Some Protocol value will turn on or off following fields.
|
| Destination IP |
Filter condition - Destination IP address.
|
| Destination Subnet Mask |
Filter condition - Destination Subnet Mask.
|
| Destination Port |
Enabled only if Protocol is TCP/UDP. Filter condition - Destination Port.
|
| Source IP |
Filter condition - Source IP address.
|
| Source Subnet Mask |
Filter condition - Source Subnet Mask.
|
| Source Port |
Enabled only if Protocol is TCP/UDP. Filter condition - Source Port.
|
| Source MAC |
Filter condition - Source MAC address.
|
| Source MAC Mask |
Filter condition - Source MAC address Mask. Empty of FF:FF:FF:FF:FF:FF means this mask can be ignored.
|
| Source Vendor Class ID |
Filter condition - Source Vendor Class ID in host's DHCP request.
|
| Source Client ID |
Filter condition - Source Client ID in host's DHCP request.
|
| Source User Class ID |
Filter condition - Source User Class ID in host's DHCP request.
|
| DSCP |
Filter condition - DSCP of LAN's incoming packet.
|
| Ethernet Priority |
Filter condition - Ethernet Priority of LAN's incoming packet.
|
| VLAN |
Filter condition - VLAN of LAN's incoming packet.
|
| Ethernet Priority Mark(802.1p) |
Mark outgoing packets with specified 802.1p value. This is optional (empty means no mark).
|
| DSCP Mark |
Mark outgoing packets with specified DSCP value. This is optional (empty means no mark).
|
| Target Interface |
Direct matching packets to this outgoing interface (all WAN connections and PVC/VLAN bridges). This is optional (empty means no traffic directing).
|
| Queue Index |
Traffic priority applies to LAN-to-WAN traffic only. Higher priority traffic is guaranteed available bandwidth.
This is useful for simultaneous activities that put a heavy load on the network (for example, a VoIP phone call during large file downloads).
Select the appropriate Queue Index (and Priority): 1-7 (lower values means higher priority).
NOTE:Traffic from the Gateway's voice lines are automatically assigned highest priority, this is not configurable by users.
