Mesh-Related Problems
Traffic on a dynamic VLAN does not get through the switch mesh .
GVRP enables dynamic VLANs. Ensure that all switches in the mesh have
GVRP enabled. (Note that ProCurve 1600M/2400M/2424M/4000M/8000M
switches do not offer GVRP. Thus, if there are any of these switches in the
mesh, GVRP must be disabled for any switch in the mesh.)
The Switch Mesh Does Not Allow A ProCurve Switch 1600M/2400M/
2424M/4000M/8000M Port To Join the Mesh . One of the switches in the
mesh domain has detected a duplicate MAC address on multiple switches. For
example:
Node “N”
5300xl, 3400cl,
or 6400cl

Illegal Topology for
Heterogeneous Mesh
Figure C-5. Example of Illegal Topology for Heterogeneous Mesh
Changing the topology can solve this problem. Also, the duplicate MAC
address must age out before the Switch 1600M/2400M/2424M/4000M/8000M
port can join the mesh. Refer to the following two topics in the “Switch
Meshing” chapter of the Advanced Traffic Management Guide for your
switch:
■ The section titled “Using a Heterogeneous Switch Mesh”
■ The bulleted item titled “Compatibility with Older Switches” in the section
titled “Requirements and Restrictions”.
Duplicate MAC Addresses on Different Switches. In a switch mesh that
includes any 1600M/2400M/2424M/4000M/8000M switches, duplicate MAC
addresses on different switches are not allowed. (The 1600M/2400M/2424M/
4000M/8000M switches do not recognize multiple instances of a particular
MAC address on different VLANs.) Refer to “The Switch Mesh Does Not Allow
A ProCurve Switch 1600M/2400M/2424M/4000M/8000M Port To Join the Mesh”
on page C-14.
