Data VLAN Result
forwarded out the PC port (to the PC) only if the
packets contain the Data VLAN tag. Untagged traffic
and traffic with a VLAN tag other than the Data
VLAN are dropped.
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.
