VLAN Considerations
This section contains information on how to administer 1603SW-I SIP IP Deskphones to
minimize registration time and maximize performance in a Virtual LAN (VLAN) environment. If
your LAN environment does not include VLANs, set the system parameter L2Q to 2 (off) to
ensure correct operation.
TCP_KEEP_ALIVE_
STATUS 1 Indicates whether TCP/IP keep-alive should be enabled
at the system. Values are 0=TCP keep alive disabled,
1=TCP keep alive enabled.
TCP_KEEP_ALIVE_TIME 60 This time interval is the time 1603SW-I SIP IP
Deskphones will wait before sending out a TCP
keep-alive message (TCP ACK message) to the far-end.
The time is controlled by the system's TCP/IP stack. The
timer is restarted after application level data (for example,
a SIP message) is sent over the socket. When the
system is idle, this keep-alive time expires and results in
sending a TCP ACK (keep-alive) packet. Valid values are
10-3600 (seconds).
TIMEFORMAT 0 Display time according to defined format in the top line
and in the call log. Values are:
0=am/pm format
1=24h format
TLSDIR " " (Null) Path name for https downloads. Character string of 0 to
127 characters representing a directory name or path to
directory.
VLANSEP 1 Enables or disables VLAN separation. Controls whether
frames to/from the secondary Ethernet interface receive
IEEE 802.1Q tagging treatment. The tagging treatment
enables frames to be forwarded based on their tags in a
manner separate from telephone frames. If tags are not
changed, no tag-based forwarding is employed. Values
are: 1=On/Enabled, 2= Off/Disabled. This parameter is
used with several related parameters. For more
information, see
VLAN Separation on page 86.
VLANTEST 60 Number of seconds to wait for a DHCPOFFER when
using a non-zero VLAN ID (1-3 ASCII digits, from “0” to
“999”).
WAIT_FOR_
REGISTRATION_TIMER 32 Time in seconds the SIP application will wait for a register
response message. If no message is received,
registration is retried. Range is 4-3600 (seconds).
