Parameters
ports - Specifies the list of port used for this configuration.
<portlist> - Enter the list of port used for this configuration here.
all - Specifies that all the ports will be used for this configuration.
announce
- (Optional) Specifies that the announce options will be configured.
interval - Specifies the mean time interval between successive announce messages. In line
with the IEEE 1588 protocol, the value of the announce interval is represented as the
logarithm to the base 2 of this time measured in seconds. If the input is not allowed, then
the input is automatically adjusted to allow the bigger and closest value. The value of the
announce interval should be uniform throughout a domain. If the announce interval of one
port changes, the announce interval of all the ports must be changed automatically to be
consistent.
<sec 1-16> - Enter the interval value used here. This value must be between 1 and 16
seconds.
timeout - Specifies the announce interval number that has to pass without receiving an
Announce message before the occurrence of the
ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES event. This value multiplied by the
announce interval value is equal to the interval time of the announce receipt timeout. The
value of the interval time of the announce receipt timeout should be uniform throughout a
domain. If the value of one port is changed, the value of all ports must be changed
automatically to be consistent.
<value 2-10> - Enter the timeout value used here. This value must be between 2 and 10
seconds.
sync_interval - (Optional) Specifies the mean time interval between successive Sync messages.
half_second - Specifies that the synchronization interval will be set to half a second.
<sec 1-2> - Enter the synchronization interval value used here. This value must be between 1
and 2.
delay_req_interval - (Optional) Specifies the permitted mean time interval between successive
delay request messages which are sent by a slave to a specific port on the master. This mean
time interval value is determined and advertised by a master.
<value 0-5> - Enter the delay required interval value used here. This value must be between 0
and 5.
pdelay_req_interval - (Optional) Specifies the permitted mean time interval between successive
pdelay_request messages.
<sec 1-32> - Enter the permitted mean time interval value used here. This value must be
between 1 and 32 seconds.
delay_mechanism
- (Optional) Specifies the mechanism for measuring the propagation delay
time of an event message.
e2e - E2E indicates that the port is configured to use the delay request-response mechanism.
p2p
- P2P indicates that the port is configured to use the peer delay mechanism.
Restrictions
Only Administrator, Operator and Power-User level users can issue this command.
Example
To configure the announce interval attribute of ports 1-4 to 3 seconds:
DGS-3420-28SC:admin# config ptp boundary ports 1:1-1:4 announce interval 3
Command: config ptp boundary ports 1:1-1:4 announce interval 3
The announce interval is automatically adjusted to 4.
Success.
