text: **Setting port mask by using the CLI and GUI**
  The command to apply a local FC port mask on CLI is**chsystem -localfcportmask mask**. The 
  command to apply a remote FC port mask is**chsystem -partnerfcportmask mask**. 
  
  If you are using the GUI, click**Settings**→**Network**→**Fibre Channel Ports**. Then, you can 
  select the use of a port. Setting*none*means no node-to-node and no replication traffic is 
  allowed, and only host and storage traffic is allowed. Setting local means only node-to-node 
  traffic is allowed, and remote means that only replication traffic is allowed. Figure 3-7 shows 
  an example of setting a port mask on port 1 to “Local”.
