DNS Addressing
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
DHCP Generic Setup 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, Table 11 ) 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:
Note:
Administer Options 6 and 15 appropriately with DNS servers and Domain names
respectively.
IEEE 802.1X
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.
