Is ES/IS (end system/intermediate system) protocol supported?
Most systems today support the ES/IS protocol. This protocol allows systems to
dynamically maintain information about the NSAP to MAC address mapping
for systems on a LAN. By using this protocol, a great deal of configuration can
be avoided.
Can this system behave as an IS?
An intermediate system is capable of forwarding traffic from one subnetwork to
an IS on another subnetwork. This system should support both the ES/IS and IS/
IS protocols. HP systems do not behave as an IS.
Will this subnetwork use the NULL subset of CLNS?
The NULL subset of CLNS is used for systems that are on an isolated LAN
network. When NULL subnetting is used, no traffic can be forwarded via
routers.
The benefit of the NULL subnet is reduced protocol packet size (on the order of
40 bytes per packet).
The drawback is the inability to communicate outside the subnetwork.
Is your LAN link configured for IEEE 802.3?
If you want to configure OTS CLNS over 802.3, you must use SAM to configure
your LAN link to use IEEE 802.3.
