3Com 3C13618 Command Reference Manual page 268

Description
Using the x25 switch svc hunt-group command, you can add an X.25 switching route
with the forwarding address as the hunt group. Using the undo x25 switch svc
hunt-group command, you can cancel the specified X.25 switching route.
By default, no X.25 switching route is configured.
After configuring the X.25 switching route with the forwarding address as the hunt
group, the corresponding X.25 call request packet will be forwarded to different
interfaces or XOT tunnels within the specified hunt group. In this way, load balancing
can be implemented when X.25 is used.
