Chapter 17 Configuring Synchronous Ethernet ESMC and SSM
How to Configure Synchronous Ethernet (SyncE): ESMC and SSM
Step 17
network-clock-select hold-timeout {timeout |
infinite}
Example:
Router(config)# network-clock-select
hold-timeout 2000
(Optional) Specifies how long the router waits before
reevaluating the network clock entry.
Step 18
esmc process
Example:
Router(config)# esmc process
Enables the ESMC process.
Step 19
network-clock external slot/card/port hold-off
{0 | milliseconds}
Example:
Router(config)# network-clock external 0/1/0
hold-off 0
Overrides the hold-off timer value for the external interface.
Step 20
network-clock quality-level {tx | rx} value
{interface type slot/card/port | external {2m |
10m} | controller {BITS | E1}
Example:
Router(config)# network-clock quality-level rx
QL-STU GigabitEthernet 0/0
Forces the QL value for line or external timing input and
output.
Step 21
interface type number
Example:
Router(config)# interface GigabitEthernet 0/0
Enters interface configuration mode.
Step 22
synchronous mode
Example:
Router(config-if)# synchronous mode
Configures the Ethernet interface to synchronous mode and
automatically enables the ESMC and QL process on the
interface.
Step 23
esmc mode [ql-disabled | tx | rx] value
Example:
Router(config-if)# esmc mode rx QL-STU
(Optional) Enables the ESMC process on the interface.
Step 24
network-clock source quality-level value
{tx | rx}
Example:
Router(config-if)# network-clock source
quality-level ql-prc tx
(Optional) Provides the forced QL value to the local clock
selection process.
Step 25
network-clock hold-off {0 | milliseconds}
Example:
Router(config-if)# network-clock hold-off 0
(Optional) Configures the hold-off timer for the interface.
