How Servers Are Sorted

In Cisco IOS® Software Release 9.1, servers are sorted in ascending order by file server type, and multiple servers of the same type are sorted in ascending order by hop count. The server of the requested type that has the lowest hop count is considered the "nearest."

In Cisco IOS Software Release 9.21 and later, servers are ordered by type, by route metric, and then by hop count as a tie breaker. A Get Nearest request for a file server chooses the server at the top of its respective type portion of the table if all servers have the same metric and hop count. Whenever a file server is taken out of service and then put back in service sometime later, it is put back in the SAP table at the top of the list for its respective type/metric. Refer to Ticks and Equal Cost Paths (IPX) for more information.

In Cisco IOS Software Release 9.21 and later, show ipx serv displays servers in a different order than the actual internal order. In order to see the internal order, use the command show ipx server unsort.

If the gns round robin feature in Cisco IOS Software Release 9.21 and later is enabled, then responses to GNS queries are balanced among servers of that type with an equal metric.

GNS responses can also be affected by configuring an output-gns-filter in Cisco IOS Software Release 9.21 and later.
