Data Priority bits

There is not a prompt for data priority bits if 802.1Q is not enabled.

PC-Port Untag all

Configure PC-Port Untag-All, which configures PC-Port VLAN Tag Stripping.

When enabled, all outgoing traffic to the PC has the VLAN tag removed. When disabled,

packets are sent to the PC as is if Data VLAN is configured as No or if Data VLAN is enabled

and the VLAN tag matched. Packets with different VLAN ID are discarded.

Cached IP

Leave unchecked to conform to the DHCP standard and to obtain an IP address from the

DHCP server. Only check Cached IP to force the IP Deskphone to start with a cached IP

address in the event that the IP Deskphone cannot connect to the DHCP server and obtain an

IP address.

Port Speed and Duplex

In the Network menu, Auto Negotiation mode is the default setting for initial startup. Typically,

the IP Deskphone is connected to a network that supports Auto Negotiation, and the

IP Deskphone selects the best speed and duplex mode available. There is no intervention

required under normal operation.

Important:

Avaya recommends that Auto Negotiation mode is used on the network and the

IP Deskphone. Use Full Duplex mode only when the entire network is running in Full Duplex

mode. Otherwise, a duplex mismatch results.

If the IP Deskphone is connected to a network configured for Full Duplex mode only, the

IP Deskphone cannot automatically negotiate the proper configuration. Therefore, in this

instance, to allow the IP Deskphone to work at the optimum speed and duplex mode, Full

Duplex mode must be enabled.
