Chapter 4-15. Troubleshooting Congestion in Fibre Channel Fabrics
show zone member: Shows the name of the zone to which a device belongs to. This command can be used to find the victims of a culprit device or vice versa. 显示设备所属的区域名称。该命令可用于查找罪魁祸首设备的受害者，反之亦然。
show zone active: Shows the members of a zone. An asterisk (*) before a device indicates that it is currently logged in to the Fibre Channel fabric. 显示区域的成员。设备前的星号 (*) 表示该设备当前已登录到光纤通道结构。
show zoneset active: Shows the active zoneset and all its members. This command can be used to find the victims of a culprit device. 显示活动的区域集及其所有成员。该命令可用于查找罪魁祸首设备的受害者。
show fcs ie: Shows all the switches in a fabric including their proximity (Local, Adjacent, or Remote), mgmt-id including domain-id, IP address and switch names. 显示 Fabric 中的所有交换机，包括距离（本地、邻近或远程）、mgmt-ID（包括域 ID）、IP 地址和交换机名称。
show fcdomain domain-list: Shows the list of the switches in the fabric. As mentioned, the domain ID of a switch makes the first octet of the FCID of a device. 显示结构中的交换机列表。如前所述，交换机的域 ID 是设备 FCID 的第一个八位位组。
show fspf database vsan <vsan_id> domain <domain_id>: Shows the details of each switch in the fabric with its domain ID and all links in the fabric including their costs. This can be used to determine the route from culprit to victim (and vice versa). 显示 Fabric 中每个交换机的详细信息，包括其域 ID 和 Fabric 中的所有链接（包括其成本）。这可用于确定从罪魁祸首到受害者（反之亦然）的路由。
show rdp: Read Diagnostic Parameter (RDP) can be used to display the information of an HBA port, such as its B2B credits, SFP information, and bit errors like CRC, ITW, and FEC as seen by the HBA port. This bit-error information is important because if the bits are corrupted after a switchport sends data but before it is received by the HBA, the local switchport can’t detect these errors, but RDP can pull these metrics in-band from the HBA port and display them on the switch. The show interface command displays the information about the local switchport, whereas show rdp com
