Parameters
x.121-address: Destination X.121 address, a pattern matching string of 1 to 15 characters. For the specific
description of pattern matching, see
must be exactly matched.
sub-dest destination-address: X.121 address, an alphanumeric string of 1 to 15 characters. The system
replaces the destination DTE address in the call request packet with the destination-address.
sub-source source-address: X.121 address, an alphanumeric string of 1 to 15 characters. The system
replaces the source DTE address in the call request packet with the source-address.
hunt-group hunt-group-name: Specifies the name of a hunt group.
xot-source interface-type interface-number: Specifies the interface whose address is to be used as the
source address for TCP connection setup. If no source interface is specified, the IP address of the
outgoing interface to the destination is used as the source IP address for TCP connection setup. When the
IP address of the outgoing interface goes invalid, the TCP connection fails. To improve TCP connection
reliability, you can specify a loopback interface as the source address for TCP connection setup. Because
a loopback interface never goes down, its IP address is always valid. A TCP connection established with
it will be maintained so long as a route is available to the destination.
Usage guidelines
After the X.25 switching SVC with forwarding address being a hunt group is configured, the relevant
X.25 call request packet will be forwarded to different 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, and enhance 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, and protect you privacy.
Examples
# Add an X.25 switching SVC, whose destination X.121 address is 1 1 1 and forwarding address is the hunt
group named hg1, and substitute the destination address with 9999 and the source address with 8888.
