The No. of NICs Installed is the total number of ATMLink
NICs installed in the system.
The Max. No. of ELANs Among the NICs is the number of
ELANs on the ATMLink NIC that has the most ELANs.
Round up the result to the first integral multiple of 16.
When NICs with different maximum frame size values are
installed, use the larger value.
Novell NetWare Considerations
ELAN Routing
Routing among ELANs is supported in configurations
where only one ELAN is configured per installed NIC.
SMP Servers
NetWare SMP servers support the Resilient Server Link (RSL)
feature only if the active and the standby NICs in an
RSL relationship share the same interrupt. NIC interrupts
on servers can usually be assigned by using the
EISA Configuration Utility (ECU) or the System
Configuration Utility (SCU) shipped with the system.
The NetWare operating system configures each ELAN and
standby NIC on a NetWare SMP server as a separate device.
NetWare allows 16 devices to share the same interrupt.
Example 1:
In an RSL configuration on an SMP server with one active
NIC with one standby NIC, the active NIC can have a
maximum of 15 ELANs.
Example 2:
In an RSL configuration on an SMP server with one standby
NIC assigned to two active NICs, 15 ELANs can be divided
between the active NICs.
Example 3:
In an RSL configuration on an SMP server with two standby
NICs assigned to one active NIC, the active NIC can have
only 14 ELANs.
