COMMAND USAGE
◆ In addition to the basic features provided by version 1, version 2 also
supports:
■
Multi-ring/ladder network support
■
Revertive/Non-revertive recovery
■
Forced Switch (FS) and Manual Switch (MS) commands for
manually blocking a particular ring port
■
Flush FDB (forwarding database) logic which reduces amount of
flush FDB operations in the ring
■
Support of multiple ERP instances on a single ring
◆ Version 2 is backward compatible with Version 1. If version 2 is
specified, the inputs and commands are forwarded transparently. If set
to version 1, MS and FS operator commands are filtered, and the switch
set to revertive mode.
◆ The version number is automatically set to “1” when a ring node,
supporting only the functionalities of G.8032v1, exists on the same ring
with other nodes that support G.8032v2.
◆ When ring nodes running G.8032v1 and G.8032v2 co-exist on a ring,
the ring ID of each node is configured as “1”.
◆ In version 1, the MAC address 01-19-A7-00-00-01 is used for the node
identifier. The raps-def-mac command has no effect.
