5. Set the stacking mode.
By default, each switch is set to Member mode. However, if the incoming switch
has been used in another stacking configuration, it may be necessary to ensure
the proper mode is set.
– If replacing a Member or Backup switch:
RS G8000(config)# boot stack mode member
– If replacing a Master switch:
RS G8000(config)# boot stack mode master
6. Configure the stacking VLAN on the new switch, or use the default setting.
Although any VLAN may be defined for stack traffic, it is highly recommended
that the default, VLAN 4090, be reserved for stacking, as shown in the following
command.
RS G8000(config)# boot stack vlan 4090
7. Designate the stacking links.
It is recommended that you designate the same number of 10Gb ports for
stacking as the switch being replaced. By default, 10Gb Ethernet port 51 and
port 52 (via optional 10GbE modules installed at the back of the switch) are
used. At least one 10Gp port is required. Use the following command to specify
the links to be used in the stacking trunk:
RS G8000(config)# boot stack higig-trunk <list of port names or aliases>
8. Attach the required stack link cables to the designated stack links on the new
switch.
9. Attach the desired network cables to the new switch.
10. Reboot the new switch:
RS G8000(config)# reload
When the new switch boots, it will join the existing stack. Wait for this process to
complete.
1. Log in to the stack interface.
Note: If replacing the Master switch, be sure to log in to the stack interface (hosted
temporarily on the Backup switch) rather than logging in directly to the newly
installed Master.
2. From the stack interface, assign the csnum for the new switch.
You can bind Member switches to a stack csnum using either the new switch's
asnum or MAC address :
RS G8000(config)# stack switch-number <csnum> mac <MAC address>
-or-
RS G8000(config)# stack switch-number <csnum> bind <asnum>
