Stp Cost - 3Com 7750 Series Command Reference Manual

3Com Switch 7750 Series
Command Reference Guide – MSTP
Note:
The digest snooping feature is needed only when your Switch 7750 is connected to
partner's proprietary protocol-adopted switches.
To enable the digest snooping feature successfully, you must first enable it on all the
switch ports that connect to partner's proprietary protocol-adopted switches and
then enable it globally.
To enable the digest snooping feature, the interconnected switches must be
configured with exactly the same MST settings.
The digest snooping feature must be enabled on all the switch ports that connect to
partners' proprietary protocol-adopted switches in the same MST region.
With the digest snooping feature enabled, the VLAN-to-MSTI mapping cannot be
modified.
The digest snooping feature is not applicable to MST region edge ports.
