SNMP
The W406-LX has built-in SNMP V1 (Simple Network Management Protocol) agent software. It
supports RFC1317 RS-232 like group and RFC 1213 MIB-II.

Æ W406-LX does NOT support SNMP trap.
Package Management—ipkg
ipkg is a very lightweight package management system. It also allows for dynamic
installation/removal of packages on a running system. Because the disk space is limited, we
provide these software as extension packages. You can use ipkg-cl to install or remove .ipk
packages on the W406-LX.
Type ‘upramdisk’ to get the free space ram disk to save the package. Check that you have enough
free space
