I have a VSS 1440 System running under IOS 12.2(33)SXI4a consisting of
2 Chassis, each with 1 Supervisor 720 10GE running PFC3CXL.
I want to add redundant Supervisories in each Chassis without interrupting
user applications. Are redundant Supervisories hot swappable ? Are
there any special considerations which must be followed when
forming a quad sup VSS System ?
