Setting the CRC Size
By default, the router uses the 16-bit CRC type. The router appends a 16-bit CRC
to the transmitted frames and performs a 16-bit CRC on received frames. You can
change to 32-bit CRC, where the router appends a 32-bit CRC to transmitted
frames and performs a 32-bit CRC on received frames.
Using the BCC
To set the crc size, navigate to the logical-line prompt (for example,
stack
;
mce1/1/2/1
;
logical-line/mce1-121-1
) and type:
crc-size
variable
For example:
logical-line/mce1-121-1#
crc-size crc-32
logical-line/mce1-121-1#
crc-size crc-16
Using Site Manager
See the CRC Size parameter on page A-40 for information.
Setting the MTU Size
The router uses the transmit/receive buffer size (MTU) to configure the largest
frame that the router can transmit or receive across this MCE1 port. The router
discards frames larger than this value. The MTU is 1600 bytes by default. You can
change it to any size from 3 to 4608 bytes for the logical line.
Using the BCC
To set the MTU size, navigate to the logical-line prompt (for example,
stack
;
mce1/1/2/1
;
logical-line/mce1-121-1
) and type:
mtu-size
integer
For example:
logical-line/mce1-121-1#
mtu-size 3
Using Site Manager
See the MTU Size parameter on page A-40 for information.
