command. Verify
that the field
switchMode
displays Access Gateway Mode.
NPIV disabled on Edge
switch ports
Inadvertently turned off
On the Edge switch, enter the
portCfgShow
command.
Verify that NPIV status for the port to which Brocade Access Gateway
is connected is ON.
If the status displays as “--” NPIV is disabled. Enter the
portCfgNpivPort
<port_number>
command with the
1
operand to
enable NPIV.
Repeat
step
for each port as required.
Need to reconfigure
N_Port and F_Ports
Default port setting not adequate for
customer environment
On Brocade Access Gateway, enter the
portCfgShow
command.
For each port that is to be activated as an N_Port, enter the
portCfgNport
<port_number>
command with the
1
operand.
All other ports remain as F_Port.
To reset the port to an F_Port, enter the
