TitleHow to add Summit X460-G2 (VIM-2q) to an existing Summit X670-G2 stack using SummitStack-V160
Objective
How to add Summit X460-G2 (VIM-2q) to an existing Summit X670-G2 stack using SummitStack-V160
Environment
  • Summit X670-G2-48x-4q
  • Summit X460-G2 (with VIM-2q)
  • SummitStack-V160
Procedure
1. Summit X460-G2 to be added is required to have a VIM-2q option card (2 x 40GbE ports) installed in the back to support SummitStack-V160.
2. Confirm the new node is running the same software version on the same partition as the existing stack by entering the command "show switch" on the new node and the master node.
3. On a Summit X460-G2 to be added, enable "stacking-support" to use native 40GbE ports as statcking ports, and reboot the switch.

 
# enable stacking-support
# configure stacking-support stack-ports all selection native v160 
# reboot
4. Connect the new node to be added to the stack using stacking cables. Various QSFP+ optics/cables can be used for stacking ports: 40G MPO cables with QSPF+ SR4 optics, QSFP+ direct-attach cables, etc.

SW1 57   --------  SW2 61
SW2 57   --------  SW3 S2
SW1 61   --------  SW3 S1

5. Only if the new node to be added is to have master capability on and be a backup node, the license level on the new node must be the same as on the master node. This can be confirmed by entering "show license" on the new node and the master node.

When the license level is different across master-capable nodes in a stack, the following command should be configured to lower the effective license to a common level. 

 
# configure stacking {node-address node-address | slot slot-number} license-level [core|advanced-edge|edge]
# reboot stack-topology or reboot node-address <node-mac-address>
6. Verify that the new node appears in the stack by entering the command "show stacking" on the master node, and enter the following commands on the master node to add the new node to the stack:
 
# synchronize stacking node-address <node-mac-address>
# configure stacking node-address <node-mac-address> slot-number <slot_number>
# configure stacking node-address <node-mac-address> master-capability <on or off> 
# enable stacking node-address <node-mac-address> 
# reboot node-address <node-mac-address>
* node-mac-address is the mac address of the new node and viewed by entering the command "show stacking" or "show stacking configuration".  
Additional notes
The command "synchronize stacking" synchronizes the following NVRAM-based stacking parameters: (These parameters are copied from the executing node's NVRAM to the target node's NVRAM.)
  • Stacking mode
  • Stack MAC address
  • The selected partition
  • Failsafe account and password
  • Failsafe account access point permissions (whether the failsafe account is allowed over the stacking links, console port, or management port)
