Microsoft Standard TCP/IP Port Monitor Futures

2. Agenda Standard TCP/IP Port Monitor (TCPMon) Port Id feature
TCPMon Print Device Type detection
TCPMon Network Card detection

3. Standard TCP/IP Port Monitor Port Id feature
Read Network Card information from the MIB-2
Request MIB-2.system.sysDescr OID ( )
Compare sysDescr against expressions inn TCPMON.INI
List of regular expressions describing supported network cards
Once matched lookup the section that contains the default port parameters for the network card
Use parameters to configure the new TCPMon port
Integrated network card or single port device simply create the new port
Multi port devices allow user to select which device port to use for printing

4. TCPMon Print Device Type detection
Additional step after port identification
New Parameter in the Port Install section
Added to TCPMon in Windows Server 2003 SP1
DEVICEIDOID# - location within the network device that contains the 1284 DeviceId for the printer attached to the current port
OID is specified per network device
Each port on the device has a separate OID for printer identification
Used in Windows Server 2003 R2 option pack to enable automatic discovery and installation of print queues

5. Evolution of TCPMon Network Card detection
Current system using TCPMON.INI works fine for existing devices
Supporting new devices is problematic
Existing OSes don’t recognize the network cards in TCPMON.INI
TCPMON.INI can be updated in future Service Packs, but there will always be lag for network admins
Current servicing model doesn’t work for Microsoft or IHVs
IHV knows the best parameters for their own network cards
Q: Where can TCPMON.INI info be stored to enable support for new devices as they are released? A: In the network card itself

6. TCPMON.INI parameters in the device
Create a new MIB section that contains the basic TCPMON.INI information or the network card
Entry to describe number of output ports device supports
Table containing an entry or each output port
Table Entry describes default parameters for an output port
Contains the information defined in TCPMON.INI syntax as OIDs.
Also contains a new entry for the 1284 Device ID of the printer reachable through the port

7. Port Table Entry specifics
PortName: OCTET_STRING – User friendly name of the port. Helps the user select the port on multi-port devices
Protocol: ENUMERATION – identifies the default protocol in TCPMON (RAW or LPR)
RAW Mode only parameters
PortNumber: INTEGER – specifies the TCP Port to use when communicating with the Printer
LPR Mode only parameters
LPRQueueName: OCTET_STRING – Queue name for LPR mode
LPRByteCountEnabled: INTEGER – Enables/Disables byte counting

8. Port Table Entry specifics (cont.)
SNMP Status paramters
SnmpStatusEnabled: INTEGER – Enables/Disables staus queries for te printer using SNMP
SnmpCommunityName: OCTET_STRING – Community name used when making SNMP status queries
SNMPResourceDeviceIndex: INTEGER – Device index of the current Port as defined in Host Resource MIB (RFC 2790)
IEEE1284Id: OCTET_STRING – String containing the 1284 Device ID for the printer connected to the current output port.

9. New TCPMon port creation procedure
During Port Creation TCPMon will look for this NumberOfPorts OID
If found walk through the SNMP table to retrieve default parameters
Use retrieved data to help user create the TCPMON port
Setup integrated ports automatically
Ask user to select which port on multi-port devices
Once port is created check for IEEE1284Id, if availbale try to install the printer driver automatically
If new OID not found fall back to MIB-2 sysDescr and use TCPMON.INI

10. Where to go from here…
Complete the definition of the new MIB table and associated OIDs
Small group of interested parties working together
& teleconference
Figure out where this new MIB extension belongs
Printer MIB?
Host Resource MIB?
MIB-2?
Finish all this in time for Longhorn Beta 1
