Example 73 Viewing port data

To display data for ports A20-A24 and trk1, you would use the command:

HP Switch(config)#: show spanning-tree a20-a24,trk1 config instance 1

Viewing the region-level configuration

This command is useful for quickly verifying the allocation of VLANs in the switch's MSTP

configuration, and for viewing the configured region identifiers.

Syntax:

show spanning-tree mst-config

NOTE: The switch computes the MSTP Configuration Digest from the VID to MSTI

configuration mappings on the switch itself. As required by the 802.1s standard,

all MSTP switches within the same region must have the same VID to MSTI

assignments, and any given VID can be assigned to either the IST or one of the

MSTIs within the region. Thus, the MSTP Configuration Digest must be identical for

all MSTP switches intended to belong to the same region. When comparing two

MSTP switches, if their Digest identifiers do not match, they cannot be members of

the same region.
