HP ProCurve 5300xl Series Management Manual page 255

Scenario 1: In a heteroge­
nous mesh, creating the
mesh with only one 5300xl,
3400cl, or 6400cl switch
connected to the host (on
VLAN 1, for example), and
then connecting a second
5300xl, 3400cl, or 6400cl
switch to the host
(regardless of the VLAN
used) results in connectivity
issues with the host.
Scenario 2: Adding the
Switch 4000M after bringing
up the mesh with two later
switches (5300xl, 3400xl, or
6400cl) already connected to
the host as shown here (with
or without separate VLANs)
blocks the Switch 4000M
from the mesh.
Figure 7-5. Example of an Unsupported Heterogeneous Topology Where Duplicate MAC Addresses Come
Through Different Switches (Regardless of the VLANs Used)
Creating the mesh with
only one Series 5300xl,
3400cl, or 6400cl switch
connected to the host,
and using tagged
VLANs for multiple
connections between
the host and the meshed
switch allows normal
meshing operation.

Note that in figures 7-5 and 7-6, if all switches are 3400cl, 6400cl, or 5300xl
devices, then you can use either topology.
Also, if you have two separate switch meshes with the topology shown in
figure 7-7, you cannot join them into a single mesh.
