Chapter 1
Hunt Groups
Hunt groups allow you to aggregate bandwidth from multiple ports
so they act as one high-bandwidth switch port. Hunt groups create
multi-gigabit pipes to transport traffic through the highest traffic
areas of your network. You can create hunt groups that interoperate
with other vendors’ equipment (for example, Cisco’s Etherchannel
and Sun’s Quad Adapter).
OpenTrunk Technology
The Avaya P550R/P580/P880/P882 Multiservice switches are
delivered as a plug-and-play IEEE 802.1D standard bridge, but
support several VLAN tagging schemes. This makes the switch
highly interoperable in existing networks because:
■ Any port can be a trunk port.
■ Ports have configurable VLAN tagging on a per-port basis.
■ Ports process a number of popular VLAN tagging schemes,
including major vendors’ proprietary schemes.
The following are features of Open Trunk Technology:
■ Frame encapsulation
— Identifies frame VLAN via tag
— Associates frame priority
■ Multiple tagging formats
— IEEE 802.1Q
— A major vendor’s multi-level tagging scheme
— 3Com VLAN Tag & PACE priority signalling
■ Translation to and from any format. A packet can enter the
switch with a 3Com SuperStack II VLAN tag and exit the
switch as a multi-layer tagged packet.
