“Whole Mess of Tools”
• Mainframe NetView • NGMF • NetView for AIX • Custom-written tools • Telnet 701 0884_04F9_c2

Typical Problem Scenario • User calls in with slow response, or loss of connectivity—might know their LU or PU name—won’t know router name • Operator looks at VTAM to identify how the LU or PU is connected— no clue • “Hunt and pecks in a database” looking for MAC address 701 0884_04F9_c2

Typical Problem Scenario (Cont.) • Finally finds one end of the connection • Telnets to router, tries to get peer address • Finds the peer, issues more line commands—“working in the dark” • Average resolution time: 20 minutes 701 0884_04F9_c2

What Happens at Your Help Desk?
• End-user can’t get to mainframe—calls help desk • Help desk doesn’t have any visibility—escalates to the mainframe network group • End-user waits 701 0884_04F9_c2

What Happens at Your Network Group? • Operator looks at NetView • If it is a “traditional session”, identifies the problem, and resolves it • If not, operator escalates to the router group,… while the end-user waits 701 0884_04F9_c2
© 1999, Cisco Systems, Inc.
11
What Happens at Your Router Group? • Operator looks at network management system or telnets to routers, and issues commands • If it is a router problem, resolves the problem • If not a router problem, back to the mainframe network group for TN3270 • End-user waits 701 0884_04F9_c2

What Happens at Your Mainframe Network Group? • Operator looks TN3270 management tool • If it is a TN3270 problem, resolves the problem • If not a TN3270 problem, ????? • End-user waits 701 0884_04F9_c2

If You’re Lucky Someone Fixes the Problem
• Takes too long • Costs too much End-user down time Operator involvement
• Situation isn’t getting any better 701 0884_04F9_c2

What Is Needed to Resolve This? • A solution that can combine information from all the environments • A solution that is easy to use, and inexpensive to implement • A solution that integrates with existing network management tools 701 0884_04F9_c2

How SNA View Works SNA View Server
• “Traditional” SNA from VTAM hosts PU/LU information from VTAM exit LU6.2 or TCP/IP
VTAM commands
SNMP SNMP
• “Book end” SNA from SNMP MIBS in routers DLSw, APPN, RSRB
• “IP client” SNA from MIBS in TN3270 servers 701 0884_04F9_c2

Case Study—With SNA View • User calls in with slow response, or loss of connectivity—might know their LU or PU name—won’t know router name • SNA view operator enters the PU or LU name • SNA view returns end-to-end session view 701 0884_04F9_c2

Case Study (Cont.)
• If problem is obvious (big red arrow), SNA view operator trouble shoots by accessing NetView, or Telnet • If problem is not obvious, escalates to level two, identifying resources in path 701 0884_04F9_c2
