The specification of Cat3550 about SVI's mac address

[mhiyoshi]

I would like to know why Cat3550 SVI's mac address is always same.

For example if I configure interface vlan1 and vlan2.

mac address is same as like 000d.bdfc.xxxx

But Cat3750 is different, each SVI has unique mac address.

Catalyst OS (CatOS) on the Supervisor Engine and Cisco IOS® Software on the Multilayer Switch Feature Card (MSFC) (Hybrid): a CatOS image can be used as the system software to run the Supervisor Engine on Catalyst 6500/6000 switches. If the optional MSFC is installed, a separate Cisco IOS Software image is used to run the MSFC.
