Additional Configurations; Setting The Mtu Size - Cisco ONS 15454 Software Feature And Configuration Manual

Configuring the ML-Series POS Interfaces
Buffer
Remote hostname :
Remote interface:
Remote IP addr
B3 BER thresholds:
SFBER = 1e-5,
Carrier delay is 200 msec

Additional Configurations

To configure additional properties to match those of the interface at the far end, perform the following
steps, beginning in global configuration mode:
Command
Step 1
Router(config-if)# no keepalive
Step 2
Router(config-if)# crc {16 | 32}

Setting the MTU Size

To set the maximum transmission unit (MTU), perform the following steps, beginning in global
configuration mode:
Command
Step 1
Router(config)# interface pos
number
Step 2
Router(config-if)# mtu bytes

Purpose
Turns off keep alive messages. Keep alive messages, though
not required, are recommended.
Sets the CRC value. If the device to which the POS module is
connected does not support the default CRC value of 32, set
both devices to use a value of 16.
Purpose
Enters interface configuration mode and specifies the POS
interface to configure.
Configures the MTU size up to a maximum of 9000 bytes. See
Table 4-3 on page 4-15.
