port to a trunk without changing the port mode in a single modify
operation. (29804)
When you insert a switching module that supports trunks on the
backplane into an unpopulated slot that has AutoMap enabled, only
the first link of the trunk for that slot is in the Up state, and other links
are in the Down state. To avoid this problem, either populate the slot
before you insert the module, or enable all backplane links in that slot
that are in the Down state. (30041)

VLANs

When defining multiple VLANs after a VLAN mode change, you
should wait a short period (5 minutes) after you change the mode
before defining additional VLANs. Moving too quickly causes the
memory on the switch fabric module to become exhausted which
further causes the module to reboot and loose the settings that have
just been changed. (30586)
