NOTE
For the VDX 6740T-1G variant, if you release Dynamic Ports On Demand (DPOD) licenses from any 10GbE ports on a 16-
port trunk configured with static 10G speed, reserve back those licenses, then perform the
shutdown
and
no shutdown
commands on all trunk ports, the trunk bandwidth will not restore to the maximum 160 Gbps.
