Cisco Stack

I am having an issue on a Cisco 3750 stack where when the stack master is rebooted, all my lacp port-channels drop and then come back up again. After doing some investigation It seems that it is happening because of lacp using the stack master mac-address as part of the system-id, so when the stack master reboots, the stack mac changes. I see that there is the command: stack-mac persistent timer 0

Bunun için ;
1.    configure terminal
2.    stack-mac persistent timer 0 (Burada aktif switch kapandığında standby switch kendi mac adresini kullanmaz ancak bir sure bekle aktif gelmezse kendi mac adresini kullan demek istersek timer suresinde değişiklik yapabiliriz.)


Step 2 stack-mac persistent timer [0 | time-value]


Example:
Switch(config)# stack-mac persistent timer 7

  Enables a time delay after an active-switch change before the stack MAC address changes to that of the new active switch. If the previous active switch rejoins the stack during this period, the stack uses that MAC address as the stack MAC address.
•        Enter the command with no value or with a value of 0 to continue using the MAC address of the current active switch indefinitely.
•        Enter a time-value from 1 to 60 minutes to configure the time period before the stack MAC address changes to the new active switch.
The stack MAC address of the previous active switch is used until the configured time period expires.
