Command Reference Guide

Administration Commands
query_nn_topology_node
Virtual routing node (VRN)
LEARN_NODE
Node type is unknown
frsn
Flow reduction sequence number. Specify 0 (zero) to return information about all nodes or a nonzero value
to return information about nodes with a FRSN greater than or equal to this value.
This parameter can be used to ensure that consistent information is obtained when you need to issue several
commands to obtain all required information. Take the following steps:
To Obtain Consistent Information Using the frsn Parameter
1. Issue query_node to get the node’s current FRSN.
2. Issue as many query_nn_topology_node commands as necessary to get all the database entries,
with the
frsn parameter set to 0 (zero).
3. Issue query_node again and compare the new FRSN with the one returned in step 1.
4. If the two FRSNs are different, the database has changed. Add 1 to the FRSN obtained in step 1, and
issue additional query_nn_topology_node commands with the frsn parameter set to this new value.
These commands return only the entries that have changed.
