What is the command to enable MAC address reduction on the 6500, or is
it done when you enable extended system-id? It doesn''t appear to be
in any Cisco docs for IOS switches; the CatOS command is "set spantree
macreduction enable."

see Comparison of the Cisco Catalyst and Cisco IOS Operating Systems
for the Cisco Catalyst 6500 Series Switch

Because the Cisco Catalyst OS and Cisco IOS Software support the
creation of 4094 Layer 2 VLANs, a MAC-address reduction feature must
be enabled so that the system can allocate a limited number of system
MAC addresses more efficiently. The following commands enable this
feature:
Cisco Catalyst OS Cisco IOS Software
set spantree macreduction enable IOS(config)# spanning-
tree extend system-id
