If the command executes successfully, the following parameters are returned:
max_nodes
Maximum number of node records in the Topology Database that were specified in the node definition. A value of 0 (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 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 a resource sequence number (RSN) less than the current RSN. Both even and odd RSNs are included in this count. These TDUs are not errors but occur when TDUs are broadcast to all adjacent network nodes. This node’s topology database is not updated, but this node sends a TDU with its higher RSN to the adjacent node that sent the low RSN.
node_equal_rsns
Total number of topology node updates received by this node with RSN equal to 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. This node’s topology database is not updated.
node_good_high_rsns
Total number of topology node updates received by this node with RSN greater than the current RSN. The node updates its topology and broadcasts a TDU to all adjacent network nodes. The node is not required to send a TDU to the sender of this update because that node already has the update.
node_bad_high_rsns
Total number of topology node updates received by this node with an odd RSN greater than the current RSN. These updates represent a topology inconsistency detected by one of the APPN network nodes. The node updates its topology and broadcasts the TDU to all adjacent network nodes.
node_state_updates
Total number of topology node updates built as a result of internally detected node state changes that affect APPN topology and routing. Node updates are sent via TDUs to all adjacent network nodes.
node_errors
Total number of topology node update inconsistencies detected by this node. A topology database update inconsistency occurs when this node attempts to update its topology database and detects a data inconsistency. This node creates a TDU with the current RSN increased to the next odd number and broadcasts it to all adjacent network nodes.
node_timer_updates
Total number of topology node updates built for this node’s resource due to timer updates. Node updates are sent via TDUs to all adjacent network nodes. These updates ensure that other network nodes do not delete this node’s resource from their topology database.
