• Stack MAC Address
The Stack MAC address is assigned automatically during the stack
initialization. The base unit’s MAC address, with an offset, is used for the
Stack MAC address.
For example, if the base unit’s MAC address is:
00-00-82-99-44-00
and the offset is:
1F
then the Stack MAC address becomes:
00-00-82-99-44-1F
If you designate another unit in the stack as the base unit, the MAC address of
the new base unit (with offset) now applies to the stack configuration.
The original stack IP address still applies to the new base unit.
Stack Configurations
As shown in Figure 1-13, the cascade connectors and cables on the 400-ST1 front
panel provide the ability to stack up to eight supported switches.
With BayStack 400-4TX MDAs installed in each switch, the stack can
accommodate a maximum of 224 switch ports.
Because stack parameters are associated with the base unit (see “
Base Unit” on
page 1-31
), the physical stack order depends on the base unit’s position and
whether the stack is configured as a stack up or a stack down configuration.
The following two sections explain the differences between stack up and stack
down configurations.
