To configure the local end to reject ACFC requests received from the peer:
Step
1. Enter system view.
2. Enter interface view.
3. Configure the local end to
reject
received from the peer.
Configuring PFC negotiation
PPP can compress the protocol field of PPP packets from 2 bytes to 1 byte to increase the payload
size.
PFC negotiation notifies the peer that the local end can receive packets with a single-byte protocol
field.
PFC negotiation is implemented at the LCP negotiation stage. After PFC negotiation is completed,
the device compresses the protocol field of sent non-LCP packets. If the first eight bits of the protocol
field are all zeros, the device does not add those bits into the packet. To ensure successful LCP
negotiation, PPP does not apply the compression to LCP packets.
As a best practice, use this configuration option on low-speed links.
To configure the local end to send PFC requests:
Step
1. Enter system view.
2. Enter interface view.
3. Configure the local end to
send
including the PFC option in
outbound LCP negotiation
requests.
To configure the local end to reject PFC requests received from the peer:
