Manual configuration of a VSF

Prerequisites
Manual configuration of a VSF requires the user to individually configure every switch in the stack, and enable VSF on each switch independently. This process provides the best control for the user to configure VSF member number, priority, and VSF links.

It is recommended to have a software version greater than or equal to 16.06.XXXX on all switches, to form a stack of size greater than four members.

An eight-member ring setup
Procedure
  1. To form an eight-member ring setup as shown, do not make the connections initially.

    The ports on each switch are Ethernet ports, and connecting as described will create a network loop. The ports are connected only after each device is fully configured.

  2. Log in to the first device, numbered . This is configured as VSF stack member 1.
    1. At the prompt, enter the following commands:
      switch# configure
      switch(config)# vsf member 1 priority 200
      switch(config)# vsf member 1 link 1 24
      All configuration on this port has been removed and port is placed in VSF mode.
      switch(config)# vsf member 1 link 2 23
      All configuration on this port has been removed and port is placed in VSF mode.
      To enable VSF, the REST interface will be disabled.
      This will save the current configuration and reboot the switch.
      Continue (y/n)? y
    2. The above sequence of commands will configure the switch as member 1, with priority 200. Since this switch has the highest priority configured, it becomes the Commander. The ports 23 and 24 are configured on VSF links 2 and 1 respectively.
  3. Log in to the second device, numbered . It is configured as VSF member 2.
    1. Physically connect member 2 with member 1 over the configured VSF ports, and execute the following commands.
      switch# configure
      switch(config)# vsf member 2 priority 150
      switch(config)# vsf member 2 link 1 25
      All configuration on this port has been removed and port is placed in VSF mode.
      switch(config)# vsf member 2 link 1 24
      All configuration on this port has been removed and port is placed in VSF mode.
      To enable VSF, the REST interface will be disabled.
      This will save the current configuration and reboot the switch.
      Continue (y/n)? y
    2. The preceding sequence of commands will configure the member 2 with priority 150.
  4. Log in to the third and fourth devices (configured as members and respectively).
    1. Physically connect member 3 with member 2. Enter the following commands on device 3:
      switch# configure
      switch(config)# vsf member 3 priority 100
      switch(config)# vsf member 3 link 1 26
      All configuration on this port has been removed and port is placed in VSF mode.
      switch(config)# vsf member 3 link 2 25
      All configuration on this port has been removed and port is placed in VSF mode.
      To enable VSF, the REST interface will be disabled.
      This will save the current configuration and reboot the switch.
      Continue (y/n)? y
    2. Physically connect member 4 with member 3. Enter the following commands on device 4:
      switch# configure
      switch(config)# vsf member 4 priority 100
      switch(config)# vsf member 4 link 1 27
      All configuration on this port has been removed and port is placed in VSF mode.
      switch(config)# vsf member 4 link 2 26
      All configuration on this port has been removed and port is placed in VSF mode.
      To enable VSF, the REST interface will be disabled.
      This will save the current configuration and reboot the switch.
      Continue (y/n)? y
  5. Log in to the fifth and sixth devices (configured as members and respectively).
    1. Physically connect member 5 with member 4. Enter the following commands on device 5:
      switch# configure
      switch(config)# vsf member 5 priority 100
      switch(config)# vsf member 5 link 1 28
      All configuration on this port has been removed and port is placed in VSF mode.
      switch(config)# vsf member 5 link 2 27
      All configuration on this port has been removed and port is placed in VSF mode.
      To enable VSF, the REST interface will be disabled.
      This will save the current configuration and reboot the switch.
      Continue (y/n)? y
    2. Physically connect member 6 with member 5. Enter the following commands on device 6:
      switch# configure
      switch(config)# vsf member 6 priority 100
      switch(config)# vsf member 6 link 1 29
      All configuration on this port has been removed and port is placed in VSF mode.
      switch(config)# vsf member 6 link 2 28
      All configuration on this port has been removed and port is placed in VSF mode.
      To enable VSF, the REST interface will be disabled.
      This will save the current configuration and reboot the switch.
      Continue (y/n)? y
  6. Log in to the seventh and eighth devices (configured as members and respectively).
    1. Physically connect member 7 with member 6. Enter the following commands on device 7:
      switch# configure
      switch(config)# vsf member 7 priority 100
      switch(config)# vsf member 7 link 1 30
      All configuration on this port has been removed and port is placed in VSF mode.
      switch(config)# vsf member 7 link 2 29
      All configuration on this port has been removed and port is placed in VSF mode.
      To enable VSF, the REST interface will be disabled.
      This will save the current configuration and reboot the switch.
      Continue (y/n)? y
    2. Physically connect member 8 with one link to member 1 and another to member 7. Enter the following commands on device 8:
      switch# configure
      switch(config)# vsf member 8 priority 100
      switch(config)# vsf member 8 link 1 23
      All configuration on this port has been removed and port is placed in VSF mode.
      switch(config)# vsf member 8 link 2 30
      All configuration on this port has been removed and port is placed in VSF mode.
      To enable VSF, the REST interface will be disabled.
      This will save the current configuration and reboot the switch.
      Continue (y/n)? y
      The remaining six members have priority set to 100. All the eight switches will be configured to use the same domain ID: 5472, which will make a single stack.
  7. Connect the switches together as shown. Enable VSF on each of the eight switches by executing the vsf enable domain 5472 command. Multiple reboots of the switches may occur since the switch roles change when connected together. To prevent this, the user can power off all switches, connect the cables, and power on together. The stack will form directly.
  8. The final VSF stack configuration after the stack formation will be:
    switch# show vsf
    VSF Domain ID    : 5472
    MAC Address      : b05ada-961103

    It indicates an eight-member VSF stack, with domain ID 5472. The stack topology is a ring, and the stack interconnect ports are of 1G speed. The user is connected to the console of member 2.
    NOTE:

    The user can alternatively add a port to a VSF link keeping it in disabled state using vsf member 1 link 1 24 start-disabled command. It is helpful when the user wants to keep the VSF ports disabled, make the connections, and then enable them back. However, VSF ports on each member have to be individually enabled for the stack formation.
