Forming an eight-member ring setup

To form an eight-member ring setup as shown, do not make the connections initially. Connect the ports only after each device is fully configured.

Procedure
  1. Log in to the first device, numbered 1.
    1. The default member number is 1, so no member number change is required.
    2. At the prompt, enter the following commands: 
      switch# configure
switch(config)# vsf member 1
switch(vsf-member-1)# link 1 1/1/25
switch(vsf-member-1)# link 2 1/1/26
    3. The preceding sequence of commands will configure the links for member 1.
    4. Ports 25 and 26 are configured as link 1 and 2 respectively.
  2. Log in to the second device, numbered 2.
    1. Execute the following commands. 
      switch# configure
switch (config)# vsf member 1
switch(vsf-member-1)# link 1 1/1/25
switch(vsf-member-1)# link 2 1/1/26
switch(vsf-member-1)# exit
switch(config)# vsf renumber-to 2
This will save the VSF configuration and reboot the switch.
Do you want to continue (y/n)? y
    2. The preceding sequence of commands will configure the links on member 2.
    3. The default member number is "1". The command "vsf renumber-to" changes this member number.
    4. Links are configured before renumbering, and the member identifier in the interface name is "1" at this point.
    5. The switch will reboot after executing the renumber command.
  3. Physically connect member 2 to member 1 as shown in the figure.
    1. This action will cause member 2 to join the stack, with member 1 as the master.
    2. This result can be verified by executing "show vsf" on member 1. 
      switch# show vsf

  4. Repeat steps 2 and 3, for each stack member 3 through 8.
    1. Be sure to specify the member number correctly on each member.
    2. If a member number conflict is detected, the member will NOT join the stack.
  5. Once member 8 has successfully joined the stack, connect member 8 link 2 to member 1 link 1, to complete the ring.

    Issue a "show vsf" command to ensure that the ring has successfully formed. 

    switch# show vsf

  6. The preceding steps will form an eight-member stack without a standby. To make any member the standby (for example, member 8), use the secondary command:
    1. From the primary VSF member, configure member 8 as VSF secondary member: 
      swtich(config)# vsf secondary-member 8
This will save the configuration and reboot the specified switch.
Do you want to continue (y/n)? y

switch(config)#
    2. This action will reboot member 8 and it will rejoin as standby. 
      switch# show vsf

  7. Alternatively, before adding member 8 to the stack, pre-configure the secondary as 8 and then renumber device 8. This action will ensure that device 8 will join the stack directly as standby.
