Use Case 2: Replacing a switch in a stack

In the above stack, member 1 has failed, and needs to be replaced. A replacement switch with the same model number (JL253A) will not take on the role of the switch it replaced, because the MAC address of the replacement switch will be different from the switch that it replaces.
To enable the configuration to assimilate the replacement switch as member 1 in the stack, the MAC address needs to be cleared. Use the CLI command
vsf member 1 type JL253A
. This will retain all configuration made on member 1 and remove only the MAC address. After the command is executed, the output of
show vsf
will be as follows:
VSF Domain ID : 164423 MAC Address : b05ada-96f043 VSF Topology : Chain VSF Status : Fragment Active Uptime : 0d 10h 34m VSF MAD : None VSF Port Speed : 1G Software Version : WC.16.03.0003 Mbr ID MAC Address Model Pri Status --- ----------------- -------------------------------------- --- --------------- 1 Aruba JL253A 2930F-24G-4SFP+ Switch 128 Provisioned *2 b05ada-96f040 Aruba JL253A 2930F-24G-4SFP+ Switch 250 Commander 3 b05ada-973680 Aruba JL262A 2930F-48G-PoE+-4SFP Sw... 250 Standby 4 b05ada-963860 Aruba JL261A 2930F-24G-PoE+-4SFP Sw... 128 Member
Subsequently, any switch model under JL253A, which is connected to the stack, will be assigned member 1 configuration and role.
