Table 294 Configure the parameters of the bundle link interface

Operation

Command

 

 

configure link identification of the multilink Frame relay

mfr link-name name

bundle link

 

 

 

Restore the default link identification

undo mfr link-name

 

 

Set the time interval for the bundle link to send Hello

mfr timer hello seconds

messages

 

 

 

Restore the default of the time interval for the bundle

undo mfr timer hello

link to send Hello messages

 

 

 

Set the number of times that the Frame Relay bundle

mfr retry number

link waits for the acknowledge timer to time out

 

successively

 

 

 

Restore the default value of the number of times that

undo mfr retry

the Frame Relay bundle link waits for the acknowledge

 

timer to time out successively

 

 

 

Set the time that the Frame Relay bundle link waits for

mfr timer ack seconds

the remote end to acknowledge the Hello message

 

 

 

Restore the default number of the time that the Frame

undo mfr timer ack

Relay bundle link waits for the remote end to

 

acknowledge the Hello message

 

 

 

The default link identification is the name of its physical interface.

By default, a bundle link will send out hello message every 10 seconds; it will send a hello message a maximum of 3 times and wait 4 seconds for a hello message acknowledgement.

Payload Compression

(FRF.9)

Introduction to Frame Relay Payload Compression

Using the Frame Relay payload compression technique to compress Frame Relay packets can effectively save the network bandwidth, and reduce the network load, hence fulfilling the highly efficient data transmission over the Frame Relay networks.

The 3Com Routers adopt FRF.9 standard to implement Frame Relay payload compression. When applied to the Frame Relay lines with relatively low bandwidth, Frame Relay payload compression can achieve significant effect.

Frame Relay Compression Configuration

Frame Relay interfaces fall into two types: point-to-point interface and multipoint interface. The methods of configuring Frame Relay payload compression are different for these two types of interfaces.

1Configure Frame Relay payload compression on point-to-point interface Perform the following configurations in interface view.

Table 295 Configure Frame Relay compression on point-to-point interface

Compression

Command

 

 

Enable Frame Relay compression

fr compression frf9

 

 

Disable Frame Relay compression

undo fr compression frf9

 

 

By default, Frame Relay payload compression is disabled.

On the 3Com Router, only the Frame Relay sub-interfaces can be point-to-point interfaces.
