Note: For many AppleTalknodes, the network address (network number and node
number) is dynamically assigned and might not be readily available.
However, there are still a number of ways to use the atecho command
effectively:
1. The AppleTalkaddress for router nodes is statically configured in many
cases. Connectivity between router nodes is critical to overall network
connectivity.
2. By setting the atecho destination node number to 255, you can query all
nodes on the specified network number on a directly attached AppleTalk
network. The received responses will indicate the node’s node number.
These node numbers can then be used to echo these nodes from distant
routers to verify connectivity.
src_netSource AppleTalknetwork number. This is an optional parameter. If not
specified, the router uses its interface network number on the outgoing
interface leading to the destination network. If the outgoing interface is an
unnumbered half-router PPP interface, the router uses any one of its LAN
interface network nodes.
src_node
Source AppleTalknode number. This is an optional parameter. If not
specified, the router uses its interface node number on the outgoing
interface leading to the destination network. If the outgoing interface is an
unnumbered half-router PPP interface, the router uses any one of its LAN
interface network nodes.
size Number of bytes to use in the AppleTalkecho requests. This is an optional
parameter. Default is 56 bytes.
rate Rate of sending AppleTalkecho requests. This is an optional parameter.
Default is one second.
Note: If you enter atecho with no parameters, you are prompted for all the
parameters. Enter values for the required parameters and either enter values
for the optional parameters or accept defaults.
Cache
The cache command displays information about the cache-size entries.
Syntax:

Example: cache
Destination Interface Usage Next Hop
122/22 1 1 27/5
138/51 0 1 27/5
23/7 1 1 Direct
Destination
AppleTalknode address (network number/node number).
Net Number of the interface used to forward to the destination node.
Usage Number of times this cache entry has been used in this aging period, which
is five seconds. An unused entry is deleted after 10 seconds.
