HARP ATM Startup Configuration Instructions
|
|
===========================================
|
|
|
|
The following steps are required in order to use the HARP ATM software.
|
|
See the file atm-config.sh for an example ATM startup script.
|
|
|
|
1. Each ATM physical interface must be configured with one or more network
|
|
interfaces. The physical interfaces are named:
|
|
|
|
FORE Systems: hfa0, hfa1, ...
|
|
Efficient Networks: hea0, hea1, ...
|
|
|
|
The network interface names and the number of network interfaces for a
|
|
particular physical interface are specified via the atm command. The
|
|
network interface name prefix may be any alphabetic string, but the
|
|
generated network interface names must be unique amongst all network
|
|
interfaces, including non-ATM interfaces.
|
|
|
|
To configure the network interfaces, type:
|
|
|
|
atm set netif <interface_name> <netif_prefix> <netif_count>
|
|
|
|
For example, the command:
|
|
|
|
atm set netif hfa0 ni 3
|
|
|
|
will generate the network interfaces ni0, ni1 and ni2 on the physical
|
|
interface hfa0.
|
|
|
|
For further details, see the man page atm(8).
|
|
|
|
|
|
2. Each ATM network interface (netif) must be configured with an IP network
|
|
address. Each network interface must be on a different IP subnet.
|
|
|
|
To configure the network interface, type:
|
|
|
|
ifconfig <netif_name> <IP_address> up
|
|
|
|
|
|
3. Each ATM physical interface must have a signalling manager attached. The
|
|
interfaces may have the same or different signalling managers.
|
|
|
|
To attach a signalling manager, type:
|
|
|
|
atm attach <interface_name> <signalling_manager_name>
|
|
|
|
where <signalling_manager_name> may be:
|
|
|
|
sigpvc - to only support PVCs on the interface;
|
|
spans - to run FORE Systems SPANS signalling protocol across
|
|
the interface, plus support of PVCs;
|
|
uni30 - to run ATM Forum UNI 3.0 signalling protocol across
|
|
the interface, plus support of PVCs;
|
|
uni31 - to run ATM Forum UNI 3.1 signalling protocol across
|
|
the interface, plus support of PVCs;
|
|
|
|
For further details, see the man page atm(8).
|
|
|
|
|
|
4. Each of the host's PVCs (if any) must be defined.
|
|
|
|
To define a PVC, type:
|
|
|
|
atm add pvc <interface_name> <vpi> <vci> <aal> <encaps> <owner> ....
|
|
|
|
where <interface_name> is the name of the ATM physical interface
|
|
over which the PVC is being defined;
|
|
<vpi> is the VPI value for the PVC;
|
|
<vci> is the VCI value for the PVC;
|
|
<aal> is the AAL type which the PVC endpoints will use;
|
|
<encaps> is the encapsulation which the PVC endpoints will use;
|
|
<owner> specifies the the owner of the PVC, which may be:
|
|
ip - the PVC is used for IP traffic;
|
|
|
|
additional parameters may be required, depending on the PVC owner:
|
|
|
|
for owner=ip,
|
|
<netif_name> is the name of the PVC's network interface;
|
|
<dst> specifies the IP address at the remote end of this PVC;
|
|
|
|
For further details, see the man page atm(8).
|
|
|
|
|
|
5. HARP includes an ILMI daemon, which will perform host address registration
|
|
with the ATM switch for ATM Forum UNI interfaces. If ILMI support is
|
|
available and activated in the ATM switch and the ILMI daemon is running
|
|
(see ilmid(8)), no further registration procedures are required.
|
|
The 'atm set prefix' command is not needed in this case.
|
|
|
|
If ILMI address registration support is not available or activated, then
|
|
the host must be manually registered with its switch. There should be
|
|
a user command available on the switch in order to do the registration.
|
|
|
|
For example, if you are using a FORE Systems switch, you should enter
|
|
the following AMI command:
|
|
|
|
> conf nsap route new <host_nsap> 152 <switch_port> 0
|
|
|
|
If you are using a Cisco LightStream 1010 switch, you would use the
|
|
following configuration command:
|
|
|
|
> atm route <host_nsap> atm <atm_interface_#> internal
|
|
|
|
For ATM Forum UNI interfaces, the 'atm set prefix' command must also
|
|
be issued when not using ILMI address registration.
|
|
|
|
|
|
6. HARP includes support for the Server Cache Synchronization Protocol (SCSP),
|
|
which can synchronize the ATMARP caches of multiple ATMARP servers.
|
|
Obviously, this is only useful on hosts which are ATMARP servers.
|
|
|
|
To run SCSP between servers, two daemons, scspd and atmarpd, must be
|
|
started. Scspd implements the SCSP protocol and atmarpd provides an
|
|
interface between scspd and the ATMARP server in the kernel. Scspd
|
|
requires a configuration file. It will look for a configuration
|
|
file at /etc/scspd.conf unless told otherwise.
|
|
|
|
An example of commands to start the two daemons is:
|
|
|
|
# scspd
|
|
# atmarpd <netif>
|
|
|
|
See the man pages scspd(8) and atmarpd(8) for further information.
