Basic System Configuration Guide System Management
Edition: 01 3HE 11010 AAAC TQZZA 357
Parameters router-name — specifies the router name used to receive NTP packets
Values Base, management
Default Base
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 to require authentication of NTP PDUs. When
enabled, NTP PDUs are authenticated upon receipt.
mda-timestamp
Syntax [no] mda-timestamp
Context config>system>time>ntp
Description This command enables more accurate timestamping for in-band NTP packets. When
enabled, timestamping is performed on an adapter card by the network processor as packets
ingress and egress the router. This reduces packet delay variability. This command can only
be set if NTP is shut down and the NTP servers are not associated with an authentication key.
This command is only supported on Ethernet-based adapter cards. This command does not
change the behavior of NTP over the management port.
The no form of this command returns the system to its default behavior of having NTP
packets timestamped by the CSM.
multicastclient
Syntax multicastclient [authenticate]
no multicastclient
Context config>system>time>ntp
Description This command configures the node to receive multicast NTP messages on the CSM
Management port. If multicastclient is not configured, received NTP multicast traffic will be
ignored. Use the show command to view the state of the configuration.
The no form of this command removes the multicast client for the specified interface from the
configuration.
Parameters authenticate — makes authentication a requirement. If authentication is required, the
authentication key-id received must have been configured in the “authentication-key”
command, and that key-id’s type and key value must also match.
