LACP-Related Problems

Unable to enable LACP on a port with the interface < port-number > lacp
command. In this case, the switch displays the following message:
Operation is not allowed for a trunked port.
You cannot enable LACP on a port while it is configured as static Trunk or FEC
trunked port. To enable LACP on static-trunked port, first use the
no trunk < port-number > command to disable the static trunk assignment, then
execute interface < port-number > lacp.
Removing a port from a trunk without first disabling the port can create a
traffic loop that can slow down or halt your network. Before removing a port
from a trunk, HP recommends that you either disable the port or disconnect
it from the LAN.
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 HP 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 An HP 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"
