Juniper JUNOSE 11.2.X MULTICAST ROUTING, Configuration Manual

Page: 144 / 256

•
Use to enable SNMP link status processing for a T1 or an E1 channel group.
•
The default is disabled.
•
Example
host1(config-controll)# path 2 ds1 1/1/1 channel-group 2 snmp trap link-status
•
Use the no version to disable SNMP link status processing for a T1 or an E1 channel
group.
•
See path ds1|e1 channel-group snmp trap link-status.
path ds1|e1 channel-group timeslots
•
Use to configure T1 or E1 line parameters.
•
You cannot configure a mixture of T1 and E1 lines on the same cOCx/STMx line module.
•
Specify a T1 or E1 channel group number, and assign a range of timeslots.
•
To configure a whole T1 or E1 line, assign all the timeslots to the channel group.
•
You can specify a line speed that applies to all DS0 timeslots assigned to a channel
group.
•
Example
host1(config-controll)# path 2 ds1 1/1/1 channel-group 2 timeslots 5-6
•
Use the no version to remove the timeslots from the channel group.
•
See path ds1|e1 channel-group timeslots.
path ds1|e1 clock source
•
Use to configure the transmit clock source for the T1 or E1 interface.
•
Select a clock as follows:
•
Specify the keyword line to use a transmit clock recovered from the line’s receive
data stream.
•
Specify the keywords internal module to use the line module’s internal clock.
•
Specify the keywords internal chassis to use the router’s clock.
•
You can usually accept the default option, line , to use a transmit clock recovered from
the line’s receive data stream, except in rare cases such as back-to-back router tests.
When performing back-to-back router tests, configure one end of the line as
internal
and the other end as line .
•
On a cOC3/STM1 I/O module, you can configure some interfaces with internal clock
sources and others with line clock sources. However, all interfaces with internal clock
sources must use either the router’s clock or the module’s clock. You cannot configure
some interfaces on the I/O module to use the router’s clock and others to use the
module’s clock.
