To display the debugging status of PPPoE, use the following command.
Command
Mode
Description
show debugging pppoe
Enable
Global
Shows the debugging status of PPPoE.
8.14 Bandwidth
Routing protocol uses bandwidth information to measure routing distance value. To
configure bandwidth of interface, use the following command.
Command
Mode
Description
bandwidth BANDWIDTH
Interface
Configures bandwidth of interface.
BANDWIDTH: 1-10000000 (unit: kbit)
no bandwidth BANDWIDTH
Deletes configured bandwidth of interface.
This bandwidth is valid only for forwarding routing information and it does not concern any
physical bandwidth.
8.15 Maximum Transmission Unit (MTU)
MTU is the largest packet size that can be sent over a network. You can set a maximum
transmission unit (MTU) with below command.
Command
Mode
Description
mtu <68-12270>
Interface
Sets a MTU size.
no mtu
Returns to the default MTU size.
8.16 Blocking Packet Forwarding
RFC 2644 recommends that system blocks broadcast packet of same network bandwidth
with interface of equipment, namely direct broadcast packet. Hereby, V5808 is supposed
to block direct broadcast packet by default setting. However, you can enable or disable it
in V5808.
To block direct broadcast packet, use the following command.
Command
Mode
Description
no ip forward direct-broadcast
Global
Enables blocking Direct broadcast packet. (Default)
ip forward direct-broadcast
Disables blocking Direct broadcast packet.
To block the destination lookup failure (DLF) packets, use the following command.
