Requirement:
Aruba 2930F-Switch running firmware version WC.16.10.0003 and Aruba Mobility-Controller running firmware version 8.x
Solution:In the following example, switch Core-Switch and mobility controller StandaloneVMC are configured for Rapid-PVST (Rapid Per-Vlan Spanning Tree).
Configuration:
---------- Mobility Controller Configuration ----------
(StandaloneVMC) [mynode] #configure terminal
Enter Configuration commands, one per line. End with CNTL/Z
(StandaloneVMC) ^[mynode] (config) #spanning-tree mode rapid-pvst
(StandaloneVMC) ^[mynode] (config) #spanning-tree vlan 108
(StandaloneVMC) ^[mynode] (config) #interface gigabitethernet 0/0/0
(StandaloneVMC) ^[mynode] (config-submode)# spanning-tree
(StandaloneVMC) ^[mynode] (config-submode)#write memory
---------- Switch Configuration ----------
Core-Switch# configure terminal
Core-Switch(config)# spanning-tree
Core-Switch(config)# spanning-tree mode rapid-pvst
Core-Switch(config)# spanning-tree vlan 108 priority 0
Verification
---------- Mobility Controller Verification ----------
