MSM7xx Controllers Configuration Guide v6.4.0

• A maximum of six trunks can be created.
• Static trunks and dynamic trunks are supported at the same time.
Static trunks
• Ports on both ends of a static trunk must have the same link speed and duplex settings, and
be of the same media type (Ethernet or fiber).
• A static trunk can combine a maximum of two ports.
• A static trunk can support multiple tagged and untagged VLANs.
Dynamic trunks
• All ports in a dynamic trunk must have the same media type (Ethernet or fiber) and speed.
(LACP enforces speed and duplex conformance across a trunk group.) For most installations,
HP recommends that you leave the port speed and duplex settings at Auto (the default).
• A dynamic trunk can combine two active ports and up to four standby ports. The MSM720
automatically activates standby ports as required.
• The MSM720 only supports LACP in active mode. However, it can connect to LACP ports
operating in passive mode.
• Each dynamic trunk supports a single untagged VLAN (called the default VLAN). This means
that traffic on the trunk is untagged, but internally within the controller traffic is tagged with a
VLAN ID for routing purposes.
• GVRP is not supported.
Creating a static trunk
This section describes how to create a static trunk using two ports. For the purposes of this example,
the trunk will connect to an HP switch using ports 3 and 4 on the MSM720. Traffic on the trunk
will be tagged with VLAN 11.
