CrossFire 8600/8605 Token-Ring Switches v. 1.2, P/N: 710001641 Switch Theory of Operation
Spanning Tree Protocol
Feature Function Benefit
IEEE 802.1D
Allows redundant
network paths to be
defined in both SRB
and transparent
switching
configurations.
No single point of failure. The
duplicate STP modes allow
operation in both transparent
and source route bridging
modes
IBM
When in SRB/SRT
mode, a combination
of IBM spanning tree
and IEEE 802.1D is
used.
Same as above, and in addition
ensures compatibility in IBM
SRB installations.
