Add node to Extreme SummitStack
Problem Description :
Need to add a node to an existing Extreme SummitStack to expand it.
Resolution :
Add a new switch into an existing stack
Procedure
Connect to new switch via telnet or serial cable in console port
On new switch, verify switch to be added is running the same EXOS version and is on the same partition as stack.
show switch
Verify that stacking protocol matches on the existing stack and the new switch.
show stacking configuration
If not seen, type show stacking detail confirm existing stack nodes and replacement nodes are using the same stacking protocol (ie. standard or enhanced).
Change stacking protocol on replacement node if needed.
configure stacking protocol <enhanced/standard>
Power down new switch and cable it up in the stack.
Power the new switch back up.
Connect to existing stack via telnet or serial cable in console port (usually slot #1)
On the existing stack, type the following commands:
configure stacking node-address <MAC_OF_NEW_SWITCH> slot <SLOT_#>
synchronize stacking node-address <MAC_OF_NEW_SWITCH>
enable stacking node-address <MAC_OF_NEW_SWITCH>
reboot node-address <MAC_OF_NEW_SWITCH>
After the new switch reboots, verify that it is in the stack with the command show slot
Additional notes
If this switch is to be master capable, it must have the same license level as the stack is currently operating at.
This can be checked with show license
Verify the stacking protocol is same as that of existing and new node to be added in stack.
If stacking is already enabled on the switch to be added to the stack, first disable it with the command disable stacking
If new switch version does not match existing slots, enter commands:
- 'download image 168.26.240.20 xos153.xos vr-default slot "slot_number"'
being sure to select install after download
- 'reboot slot "slot_number"'
OLD METHOD
- Power down all switches in stack
- Connect stack cables to include new switch at bottom of stack
- Power on all switches including new switch in stack. Existing switches should indicate their slot # on front display. New switch should have blank slot #.
- Telnet to the stack or connect via serial cable to the stack master (Slot #1)
- Enter command 'enable stacking node-address "mac-of-new-node"' to enable stacking on new switch
- Enter command 'configure stacking mac-address' to sync mac address of stack to new switch
- Enter command 'configure stacking node-address "mac-of-new-node" slot-number next_slot#' to assign new switch the next slot #.
- If switch is configured to be a Master enter command 'configue stacking node-address "mac-of-new-node" master-capable off'
- Do a 'save' command for grins
- Enter command 'reboot stack'
After each command above, you will probably receive a warning that the command will take effect after stack reboot. Do not reboot until all commands have been entered.
To verify the addition worked, log back onto the stack and enter command "show stacking" and the new switch should now display its slot #.
