not a switch failure or removal. For example, a failure of switch A
would isolate LAN 1 from connecting to LAN 2 or LAN 3.
Port Aggregation
Port aggregation is used to combine a number of ports together to
make a single high-bandwidth data pipeline. The participating
parts are called members of a link aggregation group, with one port
designated as the master portof the group. Since all members of
the link aggregation group must be configured to operate in the
same manner, the configuration of the master port is applied to all
members of the link aggregation group. Thus, when configuring
the ports in a link aggregation group, you only need to configure
the master port.
The DES-3326 supports 6 link aggregation groups, which may
include from 2 to 8 switch ports each, except for a Gigabit link
aggregation group which consists of the 2 (optional) Gigabit
Ethernet ports of the front panel. These ports are the two
1000BASE-SX, -LX –TX or GBIC ports contained in a front-panel
mounted module.
The DES-3326 allows the creation of up to 6 link aggregation
groups, each group consisting of up to 8 links (ports). The
aggregated links must be contiguous (they must have sequential
port numbers), except the two (optional) Gigabit ports – which can
only belong to a single link aggregation group.
