When configuring static trunks on switches of different types, they
◆
must be compatible with the Cisco EtherChannel standard.
The ports at both ends of a trunk must be configured in an identical
◆
manner, including communication mode (that is, speed, duplex mode
and flow control), VLAN assignments, and CoS settings.
Any of the ports on the front panel can be trunked together, including
◆
ports of different media types.
All the ports in a trunk have to be treated as a whole when moved
◆
from/to, added or deleted from a VLAN.
STP, VLAN, and IGMP settings can only be made for the entire trunk.
◆
ROUPS
Use the Trunk Group Setting page to configure the aggregation type and
members of each trunk group.

UIDELINES
When configuring static trunks, you may not be able to link switches of
◆
different types, depending on the manufacturer's implementation.
However, note that the static trunks on this switch are Cisco
EtherChannel compatible.
To avoid creating a loop in the network, be sure you add a static trunk
◆
using the configuration interface before connecting the ports, and also
disconnect the ports before removing a static trunk through the
configuration interface.
Trunk Group Settings also apply to LACP (see
◆
page
54).
