Default Switch Stack Configuration
Table 7-3 shows the default switch stack configuration.
Enabling Persistent MAC Address
The MAC address of the master determines the stack MAC address. When a master is removed from the
stack and a new master takes over, the MAC address of the new master to become the new stack MAC
address. However, you can set the persistent MAC address feature with a time delay before the stack
MAC address changes. During this time period, if the previous master rejoins the stack, the stack
Master failure Remove (or power off) the master. One of the remaining stack members
becomes the new master. All other
members in the stack remain members and
do not restart.
Add more than four
members
1. Through their stack ports, connect ten switches.
2. Power on all switches.
Two switches become masters. One
master has four stack members. The other
master remains a standalone switch.
Use the Mode button and port LEDs on the
switches to identify which switches are
masters and which switches belong to
each master. For information about the
Mode button and the LEDs, see the
hardware installation guide.
