Complete Command List
store tcpip tcp opts [-]keepalive [-]disbufmgmt
[-]zeroIArp [-]keepalivedata
example: store tcpip tcp opts keepalive -disbufmgmt
Controls whether the Ethernet Interface maintains a connection
with a host when data cannot be accepted into its buffer.
Normally the keepalive feature is enabled so when the
printer cannot accept data, the print job connection is
maintained and continued once the situation clears. If
disbufmgmt is disabled (i.e., "-"), the Ethernet Interface will
not buffer any data when there is a blocked situation with the
printer. Normally, it is best to have both keepalive and
disbufmgmt enabled. The keepalivedata option determines
whether keepalive messages should include a "garbage" data
byte for compatibility with enfironments that require it.
store tcpip tcp opts zeroIPArp
example: store tcpip tcp opts zeroIPArp
If zeroIPArp is disabled then a Ethernet Interface with an IP
address of 0.0.0.0 will not allow IP access until the IP address
is configured. If zeroIPArp is enabled on an Ethernet Interface
with an IP address of 0.0.0.0 then any attempted access with a
valid IP address is assumed for this Ethernet Interface and an
Arp lookup is performed.
Default: enabled
store tcpip tcp access [root] add|del IPaddress
example: store tcpip tcp access add 192.75.11.25
Add or remove an entry from the Ethernet Interface TCP
access list defined by IPaddress. If the list has an entry, only
this host can print to and remotely interact with the print server.
store tcpip from default|current
example:store tcpip from default
Set all TCP/IP network settings back to factory defaults.
store tcpip from current
Store all current TCP/IP network settings to flash memory so
they are retained after a power cycle. This ensures all current
settings match what is stored in flash memory.
