Vanguard Point-to-Point Protocol over Ethernet (PPPoE)
Release 6.2 or greater now enables Vanguard 7300 Series, 6435/6455, 340, 342 and
320 to utilize high-speed WAN access applications with broadband modems. A
typical environment would be DSL, cable and wireless. For more information, refer
to the Point-to-Point Protocol Manual (Part Number T0106-08).
Vanguard 6435/6455 Flash and CMEM Increase
Release 6.2 and greater allows the Vanguard 6435 and 6455 to increase the FLASH
memory and expand the CMEM area. Existing Vanguard 6435 and 6455’s can be
updated to 8 Mbyte SIMM as long as the bootprom is also updated. A new
bootprom is required to support the 12MB Flash option with the 128 kbyte CMEM.
To use 128k CMEM, 8 Mbyte SIMM must be installed and the bootprom updated.
Note
The 8meg SIMM is not officially supported prior to release 6.2, however it can
be installed in a 6455 running a 6.1 release without harm. It will simply be
recognized and treated as a "4 Meg SIMM".
Once a node is running 6.2 with the presence of an 8meg flash SIMM you cannot
downgrade either the software or SIMM size as the configuration will be deleted.
