Can only snoop with one source port and one destination port in 8540???

Release Notes for the Catalyst 8540 for Cisco IOS Release 12.1(12c)E

May 28, 2002

Catalyst 8540 Cisco IOS Release 12.1(12c)E

Restrictions

Port Snooping Restrictions

The snooping source port and destination port cannot be the same port.

You can only snoop with one source port and one destination port.

Snooping configuration information is not saved in NVRAM.

You cannot snoop a port that is part of a bridge group

"You can only snoop with one source port and one destination port." ??? !!!

What does it mean? In 8540 MSR, I can only listen to one port? If it is like that, what the use of snooping?

Worsely, I can not find snoop command at all in 12.1(12c)E !

What's the matter ???
