3-27

6. Configure a key number for trusted time sources with the sntp trusted-key

command in Global Configuration mode. For SNTP, configure the keys you are

allowed to use when you configure the BSR to synchronize its time with other

systems on the network.

MOT(config)#sntp trusted-key <1-4294967295>

where:

1-4294967295 is the key number for the trusted time sources.

7. To display information about SNTP, use the show sntp command in Privileged

EXEC mode.

MOT#show sntp

8. Verify that the information was entered correctly by displaying the running

configuration.

MOT#show running-config

Configuring UDP Broadcast Relay

Network hosts occasionally employ UDP broadcasts to determine address,

configuration, and name information. If such a host is on a network segment that does

not include a server, UDP broadcasts are normally not forwarded. You can configure

an interface to forward certain classes of broadcasts to a helper address. You can have

more than one helper address per interface. You can specify a UDP destination port to

control which UDP services are forwarded.

1. Use the ip forward-protocol udp command in Global Configuration mode to

enable forwarding of UDP broadcasts for a specific UDP port and specify the

protocols to forward and over which ports, as shown below:

MOT(config)#ip forward-protocol udp [<0-65535> | <bootpc> | <bootps> |

where:

0-65535 is the UDP port number.

bootpc is the Bootstrap Protocol (BOOTP) client (68).

bootps is the Bootstrap Protocol (BOOTP) server (67).
