# crc

#### Syntax

crc { 16 | 32 | none }

no crc

#### Release Information

Command introduced before JUNOSe Release 7.1.0.

#### Description

Sets the size of the cyclic redundancy check. CRC is an error-checking technique that uses a calculated numeric value to detect errors in transmitted data. 16 and 32 indicate the number of check digits per frame that are used to calculate the FCS. Both the sender and receiver must use the same setting. The default value is 16. The no version restores the value to the default.

#### Options

- 16—Specifies CRC-16, which transmits streams of 8-bit characters and generates 16-bit check bits per frame
- 32—Specifies CRC-32, which transmits longer streams at faster rates and therefore provides better ongoing error detection
- none—Disables CRC checking
