The network monitor provides status on the LAN interfaces
in a given node. It monitors all interfaces visible when you run
the lanscan command on a system.
The MIB variable ifOperStatus,
which is part of MIB-2, provides the LAN
interface status to the monitor. The MIB value
of TESTING is reported by the monitor as DOWN.
To
verify the operational status of the LAN interface,
use the lanscan (1M) or lanadmin(1M)
commands.
Table 4-1 Interpreting
LAN Interface Status
Resource Name | /net/interfaces/lan/status/LANname |
|---|
Condition | Value | Interpretation |
|---|
UP | 1 | The LAN interface is sending and receiving
packets. |
DOWN | 2 | The LAN interface is not passing operational
packets. |
EMS HA Monitors depend on
TCP/IP (or UDP) to send events
to targets such as HP OpenView IT/Operations or MC/ServiceGuard;
see "Which Protocols Can I Use to Send Events"
in Chapter 1. If all LAN interfaces on a subnet
fail, notifications may not be received by a remote target.
Standby
LANs are reported as DOWN unless they have been activated to replace
a failed LAN interface.
The minimum polling interval is 30 seconds.
