stack slot 0 renumber 2
stack slot 2 priority 100
stack reserved-vlan 4093
stack timer mac-address switch-delay 10
interface stack-port 2/1
port interface 40GE2/0/1 enable
port interface 40GE2/0/2 enable
interface stack-port 2/2

第二台：

stack enable
stack slot 0 renumber 1
stack slot 1 priority 200
stack reserved-vlan 4093
stack timer mac-address switch-delay 10

处理过程

修改配置：

第一台：

stack enable
stack slot 0 renumber 2
stack slot 2 priority 100
stack reserved-vlan 4093
stack timer mac-address switch-delay 10
interface stack-port 2/2
port interface 40GE2/0/1 enable
port interface 40GE2/0/2 enable

第二台：

stack enable
stack slot 0 renumber 1
stack slot 1 priority 200
stack reserved-vlan 4093
stack timer mac-address switch-delay 10
interface stack-port 1/1
port interface 40GE1/0/1 enable
port interface 40GE1/0/2 enable

根因

根据产品文档：

FSP/3/LOGPORT_ILLEGAL: OID [OID] Stack port [octet1] connects to [octet2], and there are port members of the same logic stack port ID.

设备的逻辑堆叠端口的连线规则是端口1中的成员端口只能与端口2中的成员端口相连，否则会报此告警。
