3.142.2 Supplied Parameters
The application supplies the following parameter:
opcode
AP_QUERY_NN_TOPOLOGY_STATS
3.142.3 Returned Parameters: Successful Execution
If the verb executes successfully, SNAplus2 returns the following parameters:
primary_rc
AP_OK
max_nodes
Maximum number of node records in the Topology Database. This value was specified on DEFINE_NODE.
A value of zero indicates no limit.
cur_num_nodes
Current number of nodes in this node’s topology database. If this value exceeds the maximum number of
nodes allowed, an Alert is issued.
node_in_tdus
Total number of Topology Database Updates (TDUs) received by this node.
node_out_tdus
Total number of Topology Database Updates (TDUs) built by this node to be sent to all adjacent network
nodes since the last initialization.
node_low_rsns
Total number of topology node updates received by this node with RSN less than the current RSN. Both even
and odd RSNs are included in this count. (These TDUs are not errors, but result when TDUs are broadcast
to all adjacent network nodes. No update to this node’s topology database occurs, but this node will send a
TDU with its higher RSN to the adjacent node that sent this low RSN.)
