All ports the mesh domain are members of all VLANs. inside
Dynamic VLANs
If GVRP is enabled, meshed ports in a switch become members of any dynamic
VLANs created in the switch in the same way that they would if meshing was
not configured in the switch. (For more on GVRP, refer to chapter 3, “GVRP”.)
Jumbo Packets
If you enable jumbo traffic on any VLAN, then all meshed ports on the switch
will be enabled to support jumbo traffic. (On a given meshed switch, every
meshed port becomes a member of every VLAN configured on the switch.) If
a port in a meshed domain does not belong to any VLANs configured to support
jumbo traffic, then the port drops any jumbo packets it receives from other
devices. In this regard, if a mesh domain includes any ProCurve 8212zl
switches, 6200yl switches, Series 5400zl switches, Series 3500yl switches,
Series 3400cl or Series 6400cl switches that are configured to support jumbo
traffic, only these switches can transmit and receive jumbo packets. Other
switch models in the mesh will drop jumbo packets as they are not supported
by those switches. For more information on jumbo packets, refer to the
chapter titled “Port Traffic Controls” in the Management and Configuration
Guide
for your switch.
