FICON switch parameters (Continued) TABLE 2
Parameter Response Comment
RSCN
transmission mode No Configures end-device RSCN Transmission Mode values such as:
• RSCN only contains single PID
• RSCN contains multiple PIDs (Default)
• Fabric addresses RSCN
Arbitrated Loop
parameters No Parameters include Send FAN frames, Enable CLOSE on OPEN received,
and Always send RSCN. Refer to the
configure command in the Fabric
OS Command Reference for more information.
System services No Enables or disables the read link status (RLS) probing performed by the
FCP daemon.
Portlog events
enable No Determines whether various types of port events are logged.
SSL attributes No Enables or disables Secure Socket Layer attributes.
RPCD attributes No Enables or disables Remote Procedure Call Daemon (RPCD) attributes.
cfgload attributes No Configures configuration upload and download parameters. Refer to the
configureChassis command in the Fabric OS Command Reference for
more information.
Web Tools
attributes No Modifies Webtools attributes such as enabling the Basic User Enabled
Perform License, Checking and Warning, Allow Fabric Event Collection,
and Login Session Timeout.
8. Enter the switchEnable command to set the switch online.
9. Enter the trackChangesSet command to enable or disable the track-changes feature and to
configure the SNMP-TRAP mode.
10. Enter the fabricPrincipal command on the switch you want to be the principal switch.
In cascaded fabrics, only one switch should be the principal. In core-edge designs, the director
class switch should be the principal.
11. Enter the portCfgSpeed command to configure port speeds.
By default, all ports are configured to auto-negotiate. Normally, the only time the port configuration
is changed is when connecting to 1 Gbps ports. Some Dense Wavelength Division Multiplexing
(DWDM) ports are known not to auto-negotiate well. Furthermore, although older 1 Gbps FICON
channels log in correctly, they will generate errors, so the speed should be forced to 1 Gbps with
1 Gbps FICON channels.
NOTE
8 Gbps ports will not auto-negotiate to 1 Gbps and cannot be configured for 1 Gbps. 16 Gbps
ports will not auto-negotiate to 2 Gbps or 1 Gbps.
12. Enter the portCfgLongDistance command for ports with fiber connections exceeding 10 km.
For ports with fiber connections exceeding 10 km, configuring the port for long distance mode
increases the number of buffer-to-buffer (BB) credits available on that port. If you have any
Extended Fabrics links, enable VC translation link initialization to stabilize them. Refer to the
Fabric OS Administrator's Guide for details on this option of the portCfgLongDistance command.
