type is payloadloop or lineloop.
If you select payloadloop, the received signal at this interface is looped through
the device. Typically, the received signal is looped back for retransmission after it
has passed through the device’s framing function.
If you select lineloop, the received signal at this interface does not go through the
framing device (minimum penetration) but is looped back out. The default is
noloop.
For example, the following command changes the loopback mode to payloadloop:
atm-e3/1/1/2/1# loopback-mode payloadloop
atm-e3/1/1/2/1#
Defining the Interface MTU
The maximum transmission unit (MTU) is the largest possible unit of data that the
physical medium can transmit. By default, the interface allows an MTU size of
4608 octets. This value can handle most packet sizes. However, you can set the
MTU to any value from 3 through 4608 octets.
To modify the interface MTU, navigate to the ATM interface prompt (for
example,
box; atm/1/1/2/1; atm-e3) and enter:
mtu <integer>
integer is the MTU size in octets.
For example, the following command sets the MTU size to 3000 octets:
atm-e3/1/1/2/1# mtu 3000
atm-e3/1/1/2/1#
Defining the Primary Clock Source
To define the clock signal source, navigate to the ATM interface prompt (for
example, box; atm/1/1/2/1; atm-e3) and enter:
primary-clock-source <value>
value is internal or loop. If you select internal, the router will generate the clock
signal source. If you select the default, loop, the clock signal source will be
external to the router.
