Avaya 1603 Guia Do Utilizador

All 1600 Series IP Telephones respond to a ping or traceroute message sent from the 
DEFINITY

®

, MultiVantage™, Avaya Communication Manager, or Avaya Distributed Office 

system or any other network source. The telephones do not originate a ping or traceroute. The 
1600 Series IP Telephones offer and support “remote ping” and “remote traceroute.” The switch 
can instruct the telephone to originate a ping or a traceroute to a specified IP address. The 
telephone carries out that instruction and sends a message to the switch indicating the results. 
For more information, see your switch administration documentation.

If applicable, the telephones test whether the network Ethernet switch port supports IEEE 
802.1P/Q tagged frames by ARPing the router with a tagged frame. For more information, see 

on page 67. If your LAN environment includes Virtual LANs (VLANs), 

your router must respond to ARPs for VLAN tagging to work properly.

For more information about the extent to which your network can support any or all of the QoS 
initiatives, see your LAN equipment documentation. See 

on page 33 about QoS 

implications for the 1600 Series IP Telephones.

All 1600 Series IP Telephones provide some detail about network audio quality. For more 
information see, 

on page 26.

For more information about IEEE 802.1P and IEEE 802.1Q and the 1600 Series IP Telephones, 
see 

on page 33 and 

on page 67. Three bits of 

the 802.1Q tag are reserved for identifying packet priority to allow any one of eight priorities to 
be assigned to a specific packet. 

●

7: Network management traffic

●

6: Voice traffic with less than 10ms latency

●

5: Voice traffic with less than 100ms latency

●

4: “Controlled-load” traffic for critical data applications

●

3: Traffic meriting “extra-effort” by the network for prompt delivery, for example, executive 

e-mail

●

2: Reserved for future use

●

0: The default priority for traffic meriting the “best-effort” for prompt delivery of the network. 

●

1: Background traffic such as bulk data transfers and backups 

Note:

 Priority 0 is a higher priority than Priority 1.
