Eg. 00007C80.0000.8609.33E9 is an IPX add in Hex. 20 Hex dig=10 B. In dual proto nets TCP/IP add is converted to Hex (4B) and used as IPX net add for uniqueness. Find IPX add: ask admn, use CDP, telnet to neighbor router,

Cisco Router: build SAP tables, respond to GNS req in locating svcs like Netware servers, saves WAN link b/w by doing this incase of remote servers, by def can’t pass SAP broadcast (can forwd if progmd), own SAP broadcast @ 60 sec,

Enable IPX routing: # config t, # ipx routing [node], (node-optional-mac add of int by def, must if R has only serial ports)

# ipx maximum paths 2 (max 512) forwards IPX pkts to mult paths. cisco does load sharing by def over parallel paths.

# ipx delay [6/1] =6 ticks, 1 hop. Tick metric- Cisco default for LAN int- 1 tick, WAN int- 6 ticks

IPX on each sub/interface for multi frames: # ipx network [number] [encapsulation encap-type] [secondary]:uses def if [encap+sec-optional] not given, # config t, # ipx routing, # int e0.1, # ipx network 3200 encap arpa sec,

Encapsulation / Frame types: Netware supports multi incompatible frames on the same media, All of them works in one media if Cisco router supports all frames. to use multi encap use subinterfaces, seconary nets. 4 types: Enet_802.3: def till Nw 3.11, Enet_802.2:def since Nw 3.12, Enet_II: supports tcp/ip & ipx, Enet_snap: supports Appletalk, ipx, tcp/ip.

Encapsulation : Ethet, Token Ring, FDDI, (Interface type, Novell Frame type, Cisco IOS key word)

Ethernet : IPX Enet_802.3: novell-ether (default), IPX Enet_802.2: sap, IPX Enet_II: arpa, IPX Enet_snap: snap

Token Ring : Token-Ring: sap (default), Token-Ring_snap: snap,

FDDI : fddi_snap: snap (default), fddi_802.2: sap IPX Fddi_raw: novell-fddi

Serial : HDLC (default)

arpa : IPX Enet_II, hdlc : HDLC on ser links, novel-ether : IPX Enet_802.3, novell_fddi : IPX Fddi_raw

sap : IEEE 802.2 on Enet, FDDI, Token ring, snap : IEEE 802.2 SNAP on Enet, FDDI, Token ring

Sub interfaces: are virtual interfaces on a Cisco router, A new way to run secondary ip, ipx adds on the same interface.

To define sub Int use # Interface ethernet slot / port. number, (number =e0.0-e0.4292967295), #config t

# int e0.100, # ipx network 2300 encap sap

Secondary address: To add multi frame types and IPX add on the same int. (No cisco support, cisco supports only sub interfaces. # config t, # int s0, # ipx network 2200 encap sap, # ipx network 3200 encap hdlc sec

Monitoring IPX on Cisco routers:.

R# sh ipx route : sh IPX routing table entries. C-conntd prim net, c-conntd sec net, S-static, F-floating static, L-local (int), W-ipx wan, R-rip, E-eigrp, N-nlsp, X-Extl., A-Aggregate, s-sec,

R# sh ipx servers: sh all net servers, SAP table with all SAP svcs, P-periodic,I- incremental, H-Hold down, S-static
R# sh ipx traffic: sh summary of No & type of both IPX RIP & SAP update pkts recd & sent @ 60 sec by the router.

R# sh ipx interface: sh status of IPX int & IPX paramtrs set on each interface. sh sap,rip info(book-ans)

R# debug ipx routing activity / events: shows IPX RIP & SAP update pkts recd & sent, live IPX as its running thro network

R# undebug ipx routing act, R# ping ipx 5200.0000.0c3f.1d86- test ipx congif, R# debug ipx sap : shows IPX SAP pkts sent & recd @ 60 sec. SAP 0x1/0x2 gen qry / resp, 0x3/0x4 GNS reqst / resp.

Extended Ping: R# ping, ipx, 5200.0000.oc3f.1d86. R # sh proto e0- also shows IPX add of an int.
