Question
Can the device calculate the
spanning tree correctly if it
works with a Cisco PVST+
device?
Do the topologies of MSTIs
meet the design?
Are there as few
overlapping paths as
possible among MSTIs?

Result Remarks
Verify that spanning tree
calculation is correct on
each device.
To avoid interoperability
issues, HP recommends you
use one of the following
solutions:
•
On the Cisco device,
□OK
configure the
□Not OK
spanning-tree mode mst
command to be
□Not related
compatible with IEEE
spanning tree protocols.
•
Set up a Layer 3
connection to the Cisco
PVST+ device if the HP
device is operating in
MSTP, RSTP, or STP
mode.
If the topologies deviate
from the design, reassign
ports to VLANs and revise
the VLAN and instance
□OK
mappings.
□Not OK
For optimal load balancing,
plan VLANs and
□Not related
VLAN-to-instance mappings
to minimize overlapping
paths among different
MSTIs.
