462 CHAPTER 26: LAPB AND X.25 CONFIGURATION COMMANDS
interfaces or XOT channels in the specified hunt group, to implement the load
sharing of X.25 protocol.
■ X.25 hunt group supports source address and destination address replacement.
With destination address replacement, you can hide X.121 address of DTE
inside the hunt group so that the outside DTE knows only the X.121 address of
the hunt group, therefore enhancing network security inside the hunt group.
With source address replacement, you can hide X.121 address of DTE outside
the hunt group so that the inside DTE knows only the source X.121 address
after replacement but not the source X.121 address the call connects, therefore
protecting you privacy.
Related command: display x25 switch-table svc.
Example # Add an X.25 switching SVC, whose destination X.121 address is 111 and
forwarding address is the hunt group hg1, and substitute the destination address
with 9999 and the source address with 8888.
