Page 49: How Port Groups Work
® ® FOS-821-access-AG104 User Guide Brocade Fabric OS Access Gateway User Guide, 8.2.x How Port Groups Work Create port groups using the ag --pgcreate command. This command groups N_Ports together as port groups. By default, any F_Ports mapped to the N_Ports belonging to a port group will become members of that port group. Port grouping fundamentally restricts failover of F_Ports to the N_Ports that belong to that group. -
