Token Ring - Source Routing Problems
When using your AXIS StorPoint CD in a Token Ring network with
bridges, you may need to change the source routing mode. Four
modes are available:
You set the source routing mode by changing the
SourceRouting
parameter in the StorPoint CD configuration file.
Off
No source routing information. This is useful in strictly
‘transparent bridge’ environments, or when using old
equipment that does not support source routing.
Single
Single route broadcast mode. This is useful when there are
no ‘transparent bridges’ and a spanning tree protocol is
successfully used by the Token Ring bridges.
All
All routes broadcast mode. Use this mode when the
spanning tree offers an unsatisfactory route, or when a
spanning tree is not constructed.
Auto
Cycle Off-Single-All modes. This is the default setting and
is useful in most environments. However, under certain
circumstances (such as extremely heavy network load,
network source routing policies, etc.) you might need to
switch to one of the other settings.
