Show IPX Servers Monitoring IPX on Cisco Routers 413 The sho ipx servers command is a lot like the display servers command in NetWare—it displays the contents of the SAP table in the Cisco router, so you should see the names of all SAP services here. Remember that if the router doesn’t have entries for remote servers in its own SAP table, local clients will never see those servers. If there are servers missing from this table that shouldn’t be, double-check your IPX network addresses and encapsulation settings. 2501A#sho ipx servers Codes: S - Static, P - Periodic, E - EIGRP, N - NLSP, H - Holddown, + = detail 9 Total IPX Servers Table ordering is based on routing and server info Type Name Net Address Port Route Hops Itf P 4 BORDER1 350ED6D2.0000.0000.0001:0451 2/01 1 Et0 P 4 BORDER3 12DB8494.0000.0000.0001:0451 2/01 1 Et0 P 107 BORDER1 350ED6D2.0000.0000.0001:8104 2/01 1 Et0 P 107 BORDER3 12DB8494.0000.0000.0001:8104 2/01 1 Et0 P 26B BORDER 350ED6D2.0000.0000.0001:0005 2/01 1 Et0 P 278 BORDER 12DB8494.0000.0000.0001:4006 2/01 1 t0 P 278 BORDER 350ED6D2.0000.0000.0001:4006 2/01 1 Et0 P 3E1 BORDER1 350ED6D2.0000.0000.0001:9056 2/01 1 Et0 P 3E1 BORDER3 12DB8494.0000.0000.0001:9056 2/01 1 Et0 The output from the router allows you to see all the IPX servers discovered through the SAP advertisements. The Type field is the type of SAP service being advertised, with 4 being a file service and 7 a print service. The other service numbers listed are specific for that type of application running on the NetWare server. The Net and Address fields are the IPX Internal network numbers configured on each server. The Port field identifies the upper layer application. The socket number for the NetWare Core Protocol (NCP) is 451.
414 Chapter 8 � Configuring Novell IPX Show IPX Route The show ipx route command displays the IPX routing table entries that the router knows about. The router reports networks to which it is directly connected, it then reports networks that it has learned of since the router has come online. 2501A#sh ipx route Codes: C - Connected primary network, c - Connected secondary network, S - Static, F - Floating static, L - Local (internal), W - IPXWAN, R - RIP, E - EIGRP, N - NLSP, X - External, A - Aggregate, s - seconds, u - uses 6 Total IPX routes. Up to 1 parallel paths and 16 hops allowed. No default route known. C 10 (NOVELL-ETHER), Et0 C 20 (HDLC), Se0 c 10a (sap), Et0 C 10b (ARPA), Et0.10 R 40 [07/01] via 20.00e0.1ea9.c418, 13s, Se0 R 50 [13/02] via 20.00e0.1ea9.c418, 13s, Se0 RouterA# The small c in the routing table tells you that it is a secondary configured IPX network. Load Balancing with IPX If you were to set up parallel IPX paths between routers, the Cisco IOS will not learn about these paths by default. The router will learn a single path to a destination and discard information about alternative, parallel, equal-cost paths. Notice in the show ipx route output above the phrase Up to 1 parallel paths and 16 hops allowed. To be able to perform a roundrobin load balance over multiple equal-cost paths, you need to add the command ipx maximum-paths [#] (with # being any number up to 64); this will allow the router to accept the possibility that there might be more than one path to the same destination. The Cisco IOS will perform per-packet load sharing by default over these parallel lines. Packets will be sent on a round-robin basis between all
