To configure a destination to which UDP packets will be forwarded, enter the following
command in Configure mode:
Configure Direct Broadcast
You can configure the SSR to forward all directed broadcast traffic from the local subnet to
a specified IP address or all associated IP addresses. This is a more efficient method than
defining only one local interface and remote IP address destination at a time with the ip-
helper command when you are forwarding traffic from more than one interface in the
local subnet to a remote destination IP address.
To forward all directed broadcast traffic to a specified IP address, enter the following
command in Configure mode:
Monitor IP Parameters
The SSR provides display of IP statistics and configurations contained in the routing table.
Information displayed provides routing and performance information.
To display IP information, enter the following command in Enable mode:

destination “helper” IP
address, and UDP port
number to forward
