Viewing ESCON Style Ports
To view the available and prohibited ESCON style ports using Device Manager, follow these steps:
Step 1 Check the ESCON Style check box to see the available and prohibited ESCON style ports.
In Figure 36-15, A stands for available and P stands for prohibited.

Port Prohibiting
To prevent implemented ports from talking to each other, configure prohibits between two or more ports.
If you prohibit ports, the specified ports are prevented from communicating with each other.
Tip You cannot prohibit a PortChannel or FCIP interface.
Unimplemented ports are always prohibited. In addition, prohibit configurations are always
symmetrically applied—if you prohibit port 0 from talking to port 15, port 15 is automatically prohibited
from talking to port 0.
Note 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.
