Configuring Frame Relay
Assign a local IP address to the circuit.
host1(config-subif)#ip address 192.32.10.2 255.255.255.0
(Optional) Use show commands to verify that your configuration changes are
correct by checking the state of the interfaces.
host1#show frame-relay lmi
host1#show frame-relay map
host1#show frame-relay pvc
(Optional) Disable the local management interface.
host1#no frame-relay keepalive
(Optional) Disable the interface.
host1(config-if)#shutdown
Use to set the number of bits used for CRC.
The 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 bits per frame that are used to calculate the
frame check sequence (FCS).
A 32-bit CRC transmits longer streams at faster rates and therefore provides
better ongoing error detection, such as for an OC12/STM4 POS module.
The default is 16. You must configure CRC (CRC16 or CRC32) to match the
configuration on the other side of the Frame Relay connection.
Example
host1(config-if)#crc 32
Use the no version to set the CRC to the default value.
See crc.
Use to specify Frame Relay as the encapsulation method for the interface.
The router uses IETF format (RFC 2427 encapsulation).
Example
host1(config-if)#encapsulation frame-relay ietf
Use the no version to remove Frame Relay configuration from an interface.
See encapsulation frame-relay ietf.
