Configuring an ICX 7650 Stacking Trunk on a Live System

Follow these steps to convert stacking ports on both ends of a link to a stacking trunk on an ICX 7650 production stack.
  1. (Optional) Enter the show stack command to verify stack configuration. 
    ICX7650-48ZP Router# show stack
T=20h23m43.6: alone: standalone, D: dynamic cfg, S: static
ID   Type          Role    Mac Address    Pri State   Comment                   
1  S ICX7650-48ZP  active  609c.9f52.2cd5 128 local   Ready
2  S ICX7650-48F   standby 609c.9f52.4643 128 remote  Ready

    active       standby                                                       
     +---+        +---+                                                        
 -3/3| 1 |3/1--3/1| 2 |3/3-                                                    
 |   +---+        +---+   |                                                    
 |                        |

Role history: N: standalone, A: active, S: standby, M: member

Current stack management MAC is 609c.9f52.2cd5
Stack ports are operating at 40G.
    The example shows a two-unit live stack configured in a ring with no trunks.
  2. (Optional) Enter the show running-config command for additional information on the stack. 
    ICX7650-48ZP Router# show running-config | inc stack
stack unit 1
  stack-port 1/3/1 
  stack-port 1/3/3
stack unit 2
  stack-port 2/3/1 
  stack-port 2/3/3
stack enable
stack rconsole-off
stack mac 609c.9f52.2cd5
rear-module stack-40g
    The example includes only stacking information in the show running-config command output. The output confirms that the ICX 7650 stack is operating in 40-Gbps stacking mode.
  3. Enter stack unit configuration mode. 
    ICX7650-48ZP Router# configure terminal
ICX7650-48ZP Router(config)#stack unit 1
ICX7650-48ZP Router(config-unit-1)#
  4. Enter the multi-stack-trunk command followed by the set of ports on either end of the live connection to include in the stacking trunk. 
    ICX7650-48ZP Router(config-unit-1)# multi-stack-trunk 1/3/1 to 1/3/2 and 2/3/1 to 2/3/2

SYSLOG: <14> Sep  7 19:13:53 System: Interface ethernet 2/3/2, state up 

ICX7650-48ZP Router(config-unit-1)# end
    The example configures a stacking trunk from ports 1/3/1 to 1/3/2 on one end of the connection to ports 2/3/1 and 2/3/2 on the other end.
  5. Enter the write memory command in privileged Exec mode to save the configuration. 
    ICX7650-48ZP Router(config-unit-1)# end

SYSLOG: <14> Sep  7 19:13:57 Security: running-config was potentially changed by operator from console

    The example saves the 40-Gbps trunk configuration.
  6. (Optional) Enter the show stack command to confirm the formation of the trunk. 
    ICX7650-48ZP Router# show stack
