Configure Switch Features
Per Port Settings
Port Name
Displays the port type and port number:
• Fa—Fast Ethernet
• Gi—Gigabit Ethernet
• Te—TenGigabit Ethernet
State
(Not available on
Stratix 8000/8300 switches)
Displays the synchronization state of the switch port with the parent or grandmaster clock:
• Initializing—The switch port is waiting while a parent or grandmaster clock is selected.
• Listening—The switch port is waiting while a parent or grandmaster clock is selected.
• Pre-master—The switch port is transitioning to change to Master state.
• Master—The switch is acting as a parent clock to the devices connected to that switch port.
• Passive—The switch has detected a redundant path to a parent or grandmaster clock. For example, two different switch ports claim the same
parent or grandmaster clock. To prevent a loop in the network, one of the ports changes to Passive state.
• Uncalibrated—The switch port cannot synchronize with the parent or grandmaster clock.
• Slave—The switch port is connected to and synchronizing with the parent or grandmaster clock.
• Faulty—Either PTP is not operating properly on the switch port or nothing is connected to the port.
• Disabled—PTP is not enabled on the switch port.
Enable
Check the checkbox for each port on which to enable PTP. You can enable one or more switch ports.
By default, PTP is enabled on all the Fast Ethernet and Gigabit Ethernet ports.
For Stratix 8000/8300 switches, only the ports on the base switch module are PTP-capable. The switch expansion modules do not support PTP.
When at least one switch port is PTP-enabled, the End to End Transparent mode is selected by default.
Delay Request Interval
(Not available on
Stratix 8000/8300 switches)
The logarithmic mean interval in seconds
Type the recommended to connected devices to send delay request messages when the switch port is in the master state.
Valid values:
• -1—half second
• 0—1 second
• 1—2 seconds
• 2—4 seconds
• 3—8 seconds
• 4—16 seconds
• 5—32 seconds
• 6—64 seconds
Default: 5 (32 seconds)
Announce Timeout
(Not available on
Stratix 8000/8300 switches)
Type the number of announce intervals, specified as the logarithmic mean in seconds, that must pass without receipt of an announce message
from the parent or grand master clock before the switch selects a new parent or grand master clock.
Valid values: 2…10
Default: 3 (8 seconds)
Announce Interval
(Not available on
Stratix 8000/8300 switches)
Type the time interval, specified as the logarithmic mean in seconds, for sending announce messages.
Valid values:
• 0—1 second
• 1—2 seconds
• 2— 4 seconds
• 3— 8 seconds
• 4—16 seconds
Default: 1 (2 seconds)
