command is addcon. If the application requires NSAP addressing, use addchan to add the
connection and cnfchan if you need to modify it. Refer to the command reference for the syntax. On
the CESM CLI:
Add a connection by executing addcon. (Alternatively, you can use addchan if your
Step 1
application requires the NSAP format of endpoint specification.) Execute addcon at both
ends of the connection—unless the remote endpoint is on port 34 of a PXM (see the note
at the end of this step).
The syntax for addcon is:
addcon <port_num> [mastership [remoteConnId] ]
•
port_num is the logical port number and is always 1.
•
mastership indicates whether this endpoint is the master or slave. 1=master.
2=slave (default).
•
remoteConnId is the identification for the connection at the slave end. The format is
nodename.slot_number.port_number.vpi.vci. For the MGX-CESM-T3 and
MGX-CESM-E3, the vpi and vci are typically 0 or 1.
For the channel number, the system always returns the number 32 for the high
Note
speed CESM. If you execute dspchan, use the channel number 32 to see details about the
channel (or dspchans—and no arguments—to see high level details about the channel).
In contrast, the dspcon command takes the port number 1 to identify the connection even
though it shows the same information as dspchan.
Optionally, you can use cnfcon to modify the connection.
Step 2
cnfcon <port_num> <CDVT> <CellLossIntegPeriod> <bufsize>
•
port_num is the port number and is always 1.
•
CDVT is a tolerable variation for the arrival time of cells. For T3, the range is
125–1447 micro seconds in 125-microsecond increments. For E3, the range is
125–1884 micro seconds in 125-microsecond increments.
•
CellLossIntegrationPeriod is the amount of time a connection can be in an error
condition before an alarm is declared. The range is 1000–65535 milli seconds.
•
bufsize is the egress buffer size in bytes. You can let the CESM compute the size by
entering 0 for bufsize or enter the number of bytes up to a maximum of 16224.
Optionally, you can use cnfswparms on a BPX 8600-series switch to configure
Step 3
connection parameters for the network segment of a three-segment connection. For a
stand-alone application, use whatever means are supported by the backbone switches.
cnfswparms <chan_num> <mastership> <vpcflag> <conn_service_type> (=cos)
<route_priority> <max_cost> <restrict_trunk_type> <pcr> <mcr> <pct_util>
•
chan_number is the channel (connection) number and is always 32.
•
mastership specifies the current endpoint as master or slave. 1=master. 2=slave
(default)
•
vpcflag indicates whether the connection is a VPC or a VCC: 1=VPC, and 2=VCC.
•
conn_service_type selects the type of service for the connection: 1=cbr, 2=vbr, 3 is not
used, 4=ubr, 5=atfr, 6=abrstd, and 7=abrfst.
