I have configured 7icx-6450 and stack with them, After the stacking the one will be the master and another one will be the slave and remaning 5 will be on stand by.
The issue is ( once the master is down than our remaing 6switches reboot automatically and selecting the master.
How we stop it, if any case master switch is down than why our remaining switch is rebooting.
Please help me out.
You should post this question the in the Ethernet Switches and Routers forum (The Op might move this one for you).
Hitless failover is supported on the ICX but is not enabled by default.
Enabling hitless stacking failover
To enable hitless stacking failover, enter the following command at the global CONFIG level of the CLI:
The command takes effect immediately. Hitless switchover is allowed, and in the event of a failover, the standby controller will take over the active role without reloading the stack.
Syntax: hitless-failover enable
Use the no form of the command to disable hitless stacking once it has been enabled.
