Cisco MDS 9000 Series

If an interface is already configured in E or TE mode and you try to prohibit that port, your prohibit
configuration is rejected. Similarly, if a port is not up and you prohibit that port, the port is not allowed to
come up in E mode or in TE mode.
Note
Configuring the Default State for Port Prohibiting
By default, port prohibiting is disabled on the implemented interfaces on the switch. As of Cisco MDS SAN-OS
Release 3.0(2), you can change the default port prohibiting state to enabled in VSANs that you create and
then selectively disable port prohibiting on implemented ports, if desired. Also, only the FICON configuration
files created after you change the default have the new default setting (see the FICON Configuration Files,
on page 279).
To change the default port prohibiting setting for all implemented interfaces on the switch, follow these steps:
Step 1 switch# config terminal
switch(config)#
Enters configuration mode.
Step 2 switch(config)# ficon port default-state prohibit-all
Enables port prohibiting as the default for all implemented interfaces on the switch.
Step 3 switch(config)# no ficon port default-state prohibit-all
Disables (default) port prohibiting as the default for all implemented interfaces on the switch.
Configuring Port Prohibiting
To prohibit port addresses in a VSAN, follow these steps:
Step 1 switch# config t
switch(config)#
Enters configuration mode.
Step 2 switch(config)# ficon vsan 2
switch(config-ficon)#
Enables FICON on VSAN 2.
Step 3 switch(config-ficon)# portaddress 7
switch(config-ficon-portaddr)#
Selects port address 7 for further configuration.
Step 4 switch(config-ficon-portaddr)# prohibit portaddress 3-5
