About DNS addressing

The 9600 Series SIP IP Telephones 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
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,
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

About IEEE 802.1X

9600 Series IP Deskphones support the IEEE 802.1X standard for Supplicant operation, and
support pass-through of 802.1X messages to an attached PC (except the 9610, which does not
have a secondary Ethernet interface). The system parameter DOT1X determines how the
deskphones handle pass-through of 802.1X multicast packets and proxy logoff, as follows:
When DOT1X = 0 (the default), the deskphone forwards 802.1X multicast packets from the
●
Authenticator to the PC attached to the deskphone and forwards multicast packets from
OR the deskphone is
not tagging frames,
OR the deskphone is
tagging frames with a
VLAN ID equal to
PHY2VLAN.
Then
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.
