retain device addresses longer. Because the switches in a mesh exchange
address information, this will help to decrease the number of unicast packets
with unknown destinations, which will improve latency within the mesh. Also,
in an IP environment, it is recommended that you configure meshed switches
with their own IP addresses. This makes the discovery mechanism more
robust, which contributes to decreased latency.
Spanning Tree Operation with Switch Meshing
Using STP with several switches and no switch meshing configured can result
in unnecessarily blocking links and reducing available bandwidth. For exam-
ple:
Figure 6-59. Example Using STP Without and With Switch Meshing
If you enable STP in a network that includes switch meshing, you should
enable STP on the meshed switches as well as the non-meshed devices. STP
sees a meshed domain as a single port. However, on edge switches in the
domain, STP will manage non-meshed redundant links from other devices.
For example:

Problem:
STP enabled and creating
traffic bottlenecks.
Solution:
Enabling meshing on links between
ProCurve switch ports removes STP
blocks on meshed redundant links.
