Configuring Switch 2000 TR in Stack
Head Unit
One of the unique characteristics of the Switch 2000
TR is its ability to be part of a stack. When installed as
members of a stack, up to 6 Switch 2000 TRs form
the equivalent of a switching chassis, managed using
the same IP address. All traffic, management, moni-
toring, and configuration tasks and inquiries operate
through the high-speed cascade interface located at
the rear of each unit. See Figure 3-1.
Configuration rules for the Switch 2000 TR are sim-
ple:
The head unit must have the lowest Unit ID
number in the stack.
The head unit should be at the bottom of the
stack.
It is recommended that each consecutive unit have
sequential Unit IDs.
To ensure redundancy each consecutive unit
should have the same IP address setting as the
head unit.
