Avaya 1603SW Guia Do Utilizador

The 1603SW-I SIP IP Deskphones support DNS addresses and dotted decimal addresses. The 
deskphone attempts to resolve a non-ASCII-encoded dotted decimal IP address by checking 
the contents of DHCP Option 6. See 

on page 50 for information. At least 

one address in Option 6 must be a valid, non-zero, dotted decimal address, otherwise, DNS 
fails. The text string for the DOMAIN system parameter (Option 15, 

) is appended to the 

address(es) in Option 6 before the deskphone attempts DNS address resolution. If Option 6 
contains a list of DNS addresses, those addresses are queried in the order given if no response 
is received from previous addresses on the list. As an alternative to administering DNS by 
DHCP, you can specify the DNS server and/or Domain name in the HTTP script file. But first 
SET the DNSSRVR and DOMAIN values so you can use those names later in the script.

Note:

Administer Options 6 and 15 appropriately with DNS servers and Domain names 
respectively. 

1603SW-I SIP IP Deskphones support the IEEE 802.1X standard for pass-through and 
Supplicant operation but only if the value of the configuration parameter DOT1XSTAT is "1" (the 
default, meaning supplicant operation is enabled, and the telephone responds only to received 
unicast EAPOL messages) or “2” (supplicant operation enabled, and telephone responds to 
received unicast and multicast EAPOL messages). If DOT1XSTAT has any other value, 

VLANSEP is “0”, 

OR the deskphone is 
not tagging frames,

OR the deskphone is 
tagging frames with a 
VLAN ID equal to 
PHY2VLAN.

Frames forwarded to the network from the secondary 
Ethernet interface will not be changed before 
forwarding. Tagging is not added or removed and the 
VLAN ID and priority does not change for frames 
received on the secondary interface. Tags are still 
removed for frames that egress from the secondary 
interface. The Ethernet switch forwarding logic 
determines whether frames received on the Ethernet 
line interface are forwarded to the secondary Ethernet 
interface or to the deskphone without regard to 
specific VLAN IDs or the existence of tags.
