Microsoft Standard TCP/IP Port Monitor Futures WHDC PowerPoint Template Notes & Handouts Monday, March 27, 2017 Microsoft Standard TCP/IP Port Monitor Futures Mike Fenelon – Software Design Engineer Windows Digital Document Platforms & Solutions Group November 2004 Microsoft Confidential - Windows Hardware & Driver Central

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

Standard TCP/IP Port Monitor Port Id feature Read Network Card information from the MIB-2 Request MIB-2.system.sysDescr OID (1.3.6.1.2.1.1.1) 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

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

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

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

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

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.

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

Where to go from here… Complete the definition of the new MIB table and associated OIDs Small group of interested parties working together Email & 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
