This table allows the users to configure and monitor the
FC Multicast parameters on all the VSANs configured on the
local switch.
An entry is automatically created in this table if there
is an entry in the fspfTable (defined in CISCO-FSPF-MIB) and
fspfOperStatus (defined in CISCO-FSPF-MIB) for that
entry is 'up'.
An entry is automatically deleted from this table if
either :
a) the fspfOperStatus in the fspfTable entry for the
corresponding VSAN changes to 'down'.
or
b) the fspfTable entry for the corresponding VSAN is
deleted.
Entries in this table can be created via
cfmMulticastRootRowStatus only as the means to specify
non-default parameter values for a VSAN either because the
VSAN is suspended or fspfOperStatus (defined in
CISCO-FSPF-MIB) for that VSAN is 'down' (VSAN state is
indicated by object vsanOperState which is defined in
CISCO-VSAN-MIB).
So an entry in this table exists when one or both of these
conditions holds:
- one or more configuration parameters have non-default
values for a VSAN which is either suspended or the
fspfOperStatus for that VSAN is down.
- the fspfOperStatus for VSAN is 'up'.
This has a number of consequences:
- an entry exists for a suspended VSAN whenever that VSAN
has non-default parameters.
- an entry cannot be created (via cfmMulticastRootRowStatus)
for a VSAN with default parameters; instead, the agent
creates/deletes an entry for a VSAN with default
parameters according to whether the fspfOperStatus is 'up'
or 'down'.
- an entry can not be created via cfmMulticastRootRowStatus
unless non-default parameter values are (simultaneously)
configured for a VSAN whose fspfOperStatus is 'down'.
- deleting an entry via cfmMulticastRootRowStatus when either
the VSAN is suspended and configured with non-default
values or the VSAN is active, is equivalent to resetting
its parameters to their default values.
If an entry is configured with default-values and the
VSAN is in suspended state, then the entry would be
deleted.
