Using Hunt Groups to Aggregate Bandwidth
between Switches
Hunt groups allow you to aggregate multiple switch ports into a
single group, effectively combining the bandwidth into a single
connection.
For example, if you connect three gigabit ports each on a pair of
switches into a hunt group, the aggregated connection will have six
gigabits of available bandwidth (full- duplex).
Hunt groups also provide fault tolerance. If a port in a hunt group
fails, the remaining ports will continue forwarding the traffic on the
link.
Features
Hunt group features include:
■
Shared traffic load.
■
Address-based traffic sorting — This keeps packets in the right
order.
■
Fault tolerance — If a port in a group fails, the remaining ports
in the group pick up the traffic load.
■
Support for any number of same-speed connections in a group
— The group is not restricted to a single module in a switch.
■
Quicker recovery from link failure — If a port in the group fails,
the remaining ports carry the load. Recovery is not limited by
STP convergence time (convergence time is the time the
network takes to resume steady-state forwarding after STP
reconfiguration).
■
Supports up to 25 groups per switch.
