Known Interoperability Issues
■
An incompatibility exists when changing link speed
from 10 Mbps half duplex to 100 Mbps half
duplex. If auto-negotiation on the Switch is
disabled and the link speed on the Switch is
changed from 10 Mbps half duplex to 100 Mbps
half duplex, there is a possibility that the link
partner will not detect the change. The link will
have to be broken and reconnected before the link
partner will detect the speed and change link
speed to 100 Mbps half duplex.

When using LACP to form a trunk with a
SuperStack 3 Switch 4400, ensure that the
Switch 4400 is running the latest software release.
Older versions of software occasionally fail to
correctly form the trunk resulting in a network
loop. Alternatively you could consider configuring
the trunk manually.
