broadcastclient
Syntax broadcastclient [router router-name] {interface ip-int-name} [authenticate]
no broadcastclient [router router-name] {interface ip-int-name}
Context config>system>time>ntp
Description Platforms Supported: 7210 SAS-D and 7210 SAS-E.
When configuring NTP, the node can be configured to receive broadcast packets on a given subnet.
Broadcast and multicast messages can easily be spoofed, thus, authentication is strongly
recommended. If broadcast is not configured then received NTP broadcast traffic will be ignored. Use
the show command to view the state of the configuration.
The no form of this command removes the address from the configuration.
Parameters router router-name — Specifies the router name used to receive NTP packets.
Values Base
Default Base
interface ip-int-name — Specifies the local interface on which to receive NTP broadcast packets. If
the string contains special characters (#, $, spaces, etc.), the entire string must be enclosed within
double quotes.
Values 32 character maximum
authenticate — Specifies whether or not to require authentication of NTP PDUs. When enabled,
NTP PDUs are authenticated upon receipt.
ntp-server
Syntax ntp-server [authenticate]
no ntp-server
Context config>system>time>ntp
Description This command configures the node to assume the role of an NTP server. Unless the server command
is used, this node will function as an NTP client only and will not distribute the time to downstream
network elements.
Default no ntp-server
Parameters authenticate — If specified, makes authentication a requirement. If authentication is required, the
authentication key-id received in a message must have been configured in the “authentication-
key” command, and that key-id’s type and key value must also match.
