This example shows adding a seventh node to a stack. Assume the original stack is connected as follows:
Slot-1 Stack.9 # show stacking stack-ports Stack Topology is a Ring Slot Port Select Node MAC Address Port State Flags Speed ---- ---- ------ ----------------- ----------- ----- ----- *1 1 Native 00:04:96:26:6a:f1 Operational C- 10G *1 2 Native 00:04:96:26:6a:f1 Operational C- 10G 2 1 Native 00:04:96:26:6c:93 Operational C- 10G 2 2 Native 00:04:96:26:6c:93 Operational C- 10G 3 1 Native 00:04:96:26:5f:4f Operational C- 10G 3 2 Native 00:04:96:26:5f:4f Operational CB 10G 4 1 Native 00:04:96:1f:a5:43 Operational CB 10G 4 2 Native 00:04:96:1f:a5:43 Operational C- 10G 5 1 Native 00:04:96:28:01:8f Operational C- 10G 5 2 Native 00:04:96:28:01:8f Operational C- 10G 6 1 Native 00:04:96:20:b2:5c Operational C- 10G 6 2 Native 00:04:96:20:b2:5c Operational C- 10G * - Indicates this node Flags: (C) Control path is active, (B) Port is Blocked
* Switch.3 # enable stacking This command will take effect at the next reboot of the specified node(s). # Display the node MAC address * Switch.4 # show stacking Stack Topology is a Daisy-Chain This node is not in an Active Topology Node MAC Address Slot Stack State Role Flags ------------------ ---- ----------- ------- --- *00:04:96:26:6c:92 - Disabled Master --- * - Indicates this node Flags: (C) Candidate for this active topology, (A) Active Node (O) node may be in Other active topology # Configure a unique slot number Switch.5 # configure stacking node-address 00:04:96:26:6c:92 slot-number 7 This command will take effect at the next reboot of the specified node(s). Switch.6 # configure stacking node-address 00:04:96:26:6c:92 license-level edge This command will take effect at the next reboot of the specified node(s).
The connection broken should be the one between node 00:04:96:20:b2:5c port 2 and node 00:04:96:26:6a:f1 port 1.
The new node 00:04:96:26:6c:92 port 1 should be connected to node 00:04:96:20:b2:5c port 2
The new node 00:04:96:26:6c:92 port 2 should be connected to node 00:04:96:26:6a:f1 port 1.
Switch.7 # reboot # Log into the stack master node before entering the next command Slot-1 Stack.13 # synchronize stacking node-address 00:04:96:26:6c:92 Slot-1 Stack.13 # reboot node-address 00:04:96:26:6c:92 Are you sure you want to reboot this stack node?
