MLP SUMMARY
Lists the status of the protocols negotiated for an active remote connection. The following are the most common
protocols:
¥ MLP (Multilink Procedure)
¥ IPNCP (IP routing Network Protocol)
¥ CCP (Compression Control Protocol)
¥ BNCP (Bridging Network Protocol)
¥ IPXCP (IPX Network Protocol)
Open indicates that the protocol is in ready state.
Stopped means that the protocol is defined, but did not successfully negotiate with the remote end.
No message means that the link is not active.
PING
This command sends an echo message, available within the TCP/IP protocol suite. The echo message is sent to a
remote node and returned in order to test connectivity to the remote node. It is particularly useful for locating
connection problems on a network.
A status message is issued for each echo message sent.
You cannot ping your own LAN address; you can ping your own WAN address.
To fit the echo message into one ATM cell in routing mode, set the length of user data down to 0 bytes (-s 0 or -l
0).
-c count Number of packets sent (from 1 to 10). The default is 5 packets.
-i wait Wait period between packets in seconds (from 1 to 10). The default is 1 second.
-s size Packet data length in bytes (from 0 to 1648). The default is 56 bytes.
-l size Same as -s size.
-I srcaddr Source IP address contained in the echo message (4 decimals separated by periods). Use this
option to force packets into a tunnel or to force use of the management address as the source
address.
ipaddr IP address (4 decimals separated by periods).
Examples:
The followng command requests 2 echo messages sent 7 seconds apart with a packet length of 34 bytes. The
messages are sent to IP address 192.168.254.2.
