Port 295 (Ethernet2/39) of VLAN0009 is root forwarding
Port path cost 4, Port priority 128, Port Identifier 128.295
Designated root has priority 4105, address 0023.04ee.be01
Designated bridge has priority 8201, address 0024.986f.3b41
Designated port id is 128.260, designated path cost 0
Timers: message age 15, forward delay 0, hold 0
Number of transitions to forwarding state: 3
Link type is point-to-point by default
BPDU: sent 31, received 3486
Port 296 (Ethernet2/40) of VLAN0009 is alternate blocking

De même pour le VLAN 10, SW-1 voit la pseudo priorité de passerelle de racine et ID de
passerelle comme même valeur de N7K-1 et de N7K-2. De nouveau, N7K-1 et N7K-2 envoient
leurs pseudo priorités indiquées configurées. Pour le VLAN 10, SW-1 voit la priorité de pont
désigné de 12298 (12288 + 10) de N7K-1 et la priorité de pont désigné de 8202 (8192 + 10) de
N7K-2 ; SW-1 choisit le lien vers N7K-2 comme lien d'expédition pour VLAN 10. de cette façon,
les commutateurs connectés de non-vpc peuvent équilibrer la charge l'état STP VLAN entre N7K-
1 et N7K-2.
