| Ethernet Parameters |
| Select to activate prioritization under 802.1p protocol (described below). |
| |
| Packet Prioritization | Y/N |
|
| |
| (802.1p) |
|
|
|
|
| Frame Type | Type II, SNAP |
| Must be set to match network’s frame type. Default is Type II. |
|
| 802.1p | A draft standard | of the IEEE about data traffic prioritization on Ethernet networks. The 802.1p |
| |
|
| draft is an extension of the 802.1D bridging standard. 802.1D determines how prioritization will |
| ||
|
| operate within a |
| ||
|
| networks (VLANs) addresses the issue of prioritization for Ethernet networks in particular. |
| ||
|
| 802.1p enacts this |
| ||
|
| reorder packets based on priority level. The descriptors for the 8 priority levels are given below. |
| ||
|
| 802.1p PRIORITY LEVELS: |
| ||
|
| LOWEST PRIORITY |
| ||
|
| 1 – Background: Bulk transfers and other activities permitted on the network, but should not |
| ||
|
| affect the use of network by other users and applications. |
| ||
|
| 2 – Spare: An unused (spare) value of the user priority. |
| ||
|
| 0 – Best Effort (default): Normal priority for ordinary LAN traffic. |
| ||
|
| 3 – Excellent Effort: The best effort type of service that an information services organization |
| ||
|
| would deliver to its most important customers. |
| ||
|
| 4 – Controlled Load: Important business applications subject to some form of “Admission |
| ||
|
| Control”, such as preplanning of Network requirement, characterized by bandwidth |
| ||
|
| reservation per flow. |
| ||
|
| 5 – Video: Traffic characterized by delay < 100 ms. |
| ||
|
| 6 – Voice: Traffic characterized by delay < 10 ms. |
| ||
|
| 7 - Network Control: Traffic urgently needed to maintain and support network infrastructure. |
| ||
|
| HIGHEST PRIORITY |
| ||
| Call Control Priority |
| Sets the priority for signaling packets. |
| |
|
| lowest priority |
|
|
|
| VOIP Media Priority |
| Sets the priority for media packets. |
| |
|
| lowest priority |
|
|
|
| Others (Priorities) |
| Sets the priority for SMTP, DNS, DHCP, and other packet types. |
| |
|
| lowest priority |
|
|
|
| VLAN ID | 1 - 4094 |
| The 802.1Q IEEE standard allows virtual LANs to be defined within a network. |
|
|
|
|
| This field identifies each virtual LAN by number. |
|
| IP Parameter | fields |
| Descriptor of current VOIP unit to distinguish it from other units in system. |
|
| Gateway Name | alphanumeric |
|
| |
| Enable DHCP | Y/N |
| Dynamic Host Configuration Protocol is a method for assigning IP address and |
|
|
| disabled by |
| other IP parameters to computers on the IP network in a single message with |
|
|
| default |
| great flexibility. IP addresses can be static or temporary depending on the |
|
|
|
|
| needs of the computer. |
|
| IP Address | n.n.n.n |
| The unique LAN IP address assigned to the MultiVOIP. |
|
| IP Mask | n.n.n.n |
| Subnetwork address that allows for sharing of IP addresses within a LAN. |
|
| Gateway | n.n.n.n |
| The IP address of the device that connects your MultiVOIP to the Internet. |
