Figure 6-62. VLAN Operation with a Switch Mesh Domain
Using Automatic Broadcast Control In Meshed Switches
To avoid duplicate replies, switch meshing does not allow ABC proxy replies
from within a switch mesh. However, an edge switch can learn of the existence
of a device on the other side of the mesh and provide a proxy reply to inquiries.
For this reason, it is recommended that you configure ABC in all meshed
switches.
Requirements and Restrictions
■ Number of Meshed Ports Configured in a Switch: You can configure
up to 24 meshed ports on the Switches 1600M/2424M/4000M/8000M.
■ Mesh Domain Size: Up to 12 switches are supported in a switch mesh
domain. The following example illustrates a meshed backbone where the
maximum meshed switch hop count is 3.
