10: mpcctab \- MPCC configuration file
11: .SH DESCRIPTION
12: The file \fBmpcctab\fR is used to configure CCI's Multi-Protocol
13: Communication Controller (MPCC).
14: The controller provides high-speed
15: synchronous communications for the \s-1POWER 6\s+1 family
16: of computers.
17: This file determines the MPCC board
18: configurations. You can download either a synchronous , bisync or
19: an asynchronous protocol to an MPCC board.
20: See \fIdlmpcc\fR(8)
21: for details.
22: .LP
23: A \fBmpcctab\fR file is supplied
24: with each MPCC release; however,
25: you can modify this file or create your own file
26: by using one of the \s-1UNIX\s+1 text editors.
27: .LP
28: The contents of the file
29: consists of entries that describe supported communication
30: protocols and their unique attributes. The protocols supported are
31: X.25, SNA, ASYNC, and BISYNC.
32: For ASYNC two different entries are possible in the
33: \fIprocol\fR field - if 16 port MPCC async is configured, then ASYNC is
34: entered; 32 port MPCC async is specified by entering 32PORT.
35: This file must reside in the directory
36: \fB/etc/mpcc\fR.
37: .SH Entry Line Format
38: An entry line consists of an \fIitem identifier\fR followed by
39: variable width arguments separated by colons. There are three
40: item identifiers: MPCC, PROTOCOL, PORT. The MPCC line in this file
41: identifies the board number. The PROTOCOL line identifies
42: the specific communication protocol.
43: The PORT line describes
44: the port for the immediately preceding protocol. The number
45: of arguments for the PROTOCOL and PORT lines,
46: and the arguments themselves,
47: are protocol dependent. See the individual
48: argument descriptions for details.
49: .LP
50: Notes: Use upper case letters for clarity when specifying the item
51: identifier and the protocol name. Make sure that you enter
52: the argument values in the order specified below. Also, use comments
53: liberally, and indicate comment lines by placing a
54: pound sign (\fB#\fR) in column one.
55: .LP
56: The item identifiers and their corresponding line
57: formats, with valid argument values, follow:

67: Argument Explanations:
68: .RS
69: .IP \fIbdno\fR 8
70: Specifies the board number.
71: .IP \fBFCCS\fR 8
72: FCCS is a fault-tolerant support system that allows backup ports
73: to assume the functions of failed ports.
74: For example,
75: if port 0 fails for any reason,
76: another port may be configured to assume the duties of the failed port.
77: The keyword \fBFCCS\fR identifies this feature and must be
78: followed by the list of fail-safe port numbers and a time increment,
79: described below.
80: This feature is optional.
81: .IP \fBSOC\fR 8
82: An FCCS port can also be an SOC (Switch On Close) port,
83: meaning that the port will switch when it is closed.
84: And as with FCCS, the port will switch if it fails.
85: This feature is optional.
86: .IP \fIportno\fR 8
87: Portno is a list of port numbers,
88: separated by commas,
89: specifying the primary ports you want protected by backup ports.
90: FCCS boards have either 4 primary and 4 backup ports,
91: or 8 primary and 8 backup ports.
92: The valid port numbers are
93: .B 0
94: through
95: .B 3
96: for the 4-port version,
97: and
98: .B 0
99: through
100: .B 7
101: for the 8-port version.
102: .IP
103: Each of the ports has a switched connector.
104: If the board fails for any reason,
105: the traffic on these ports is automatically routed
106: through the switched connector.
107: These connectors must be cabled to secondary ports on the other FCCS
108: connector panels.
109: The secondary ports are numbered 8 through 11 on the 4-port version and
110: 8 through 15 on the 8-port version.
111: Only the primary ports need be designated in the FCCS configuration line,
112: however all ports must be identified as described in the PORT Line section
113: below.
114: .if n .bp
115: .IP \fItime\fR 8
116: Specifies the time period for the sentinel relay timer.
117: Each board resets its sentinel timer after the specified
118: time period. If the
119: board fails, and therefore can't set the timer, then control
120: is passed automatically to another board, which continues
121: the current processing. This feature ensures PerpetualProcessing
122: and is transparent to the user. The valid range of values
123: in milliseconds is from \fB50\fR to \fB5950\fR in
124: 50 millisecond increments.
