Known issues
Description

Reference

If you insert an IOM into a running TXE device without cycling through a cold boot afterwards,
Layer-2 Fallback (L2FB) for the segments on that specific IOM will not work. Despite being fully
functional from an inspection point of view, the segments on that module will not pass traffic if
the device enters L2FB for any reason (including user-initiated L2FB, automatic L2FB during awarm reboot, and automatic L2FB caused by specific events).
To avoid this issue, take one of the following actions:•••

Insert an IOM only while the TXE device is powered off.
Whenever you insert an IOM while the TXE device is running, make sure the device
goes through a complete power cycle afterwards.
From the device CLI, enter reboot full after inserting an IOM into a running TXE
device.
