Configuring additional F_Ports
4
switch:admin> ag --failbackenable 13
Failback policy is enabled for port 13
To disable failback
1. Connect and log in to the switch.
2. Enter the ag
--failbackshow command with the n_portnumber operand to display the failover
setting.
switch:admin> ag --failbackshow 13
Failback on N_Port 13 is supported
3. Enter the ag --failbackdisable command with the n_portnumber operand to disable failover.
switch:admin> ag --failbackdisable 13
Failback policy is disabled for port 13
Configuring additional F_Ports
By default on the embedded switches, only the internal ports of Brocade Access Gateway are
configured as F_Ports. All external ports are configured (locked) as N_Ports. For more information
on which ports are mapped by default, refer to Appendix A, “Default Port Mapping”. The internal
ports connect hosts in the bladed server and external ports connect to the fabric. To connect an
additional FCP initiator to an external port, reconfigure an N_Port as an F_Port as follows:
1. Remap any F_Ports on the N_Port that is being converted. See “Adding F_Ports” on page 19.
2. Unlock N_Port mode to change the port type to an F_Port. See “Unlocking N_Port mode” on
page 24.
3. Map the newly configured F_Port to an N_Port. See “Adding F_Ports” on page 19.
4. Connect the HBA, host, or other FCP initiator to the F_Port
NOTE
A switch in Access Gateway mode must have at least one port configured as an N_Port.
Therefore the maximum number of F_Ports that could be mapped to an N_Port is the number
of ports on the switch minus one.
