The HA Network Interface Monitor provides status on the LAN interfaces in a
given node. It monitors all the interfaces that you see when you
run the lanscan command on a system.
The HA Network Interface Monitor is part of the MIB Monitors package. Table 7-1 “HA Network Interface Monitor Names and Resources” lists the HA Network Interface Monitor.
Table 7-1 HA Network Interface Monitor Names and Resources
| Monitor | Resource Type | Resource |
|---|
| lanmond | LAN Interface | /net/interfaces/lan/status/
<LANname> |
Figure 7-1 “Network Monitor Resource Class Hierarchy” illustrates the network monitored
resources.
The MIB-2 variable, ifOperStatus, provides the LAN interface status to the monitor. The monitor reports DOWN if it read the MIB value of TESTING. See Table 7-2 “Interpreting LAN Interface Status”.
To verify the operational status of the LAN interface, use the lanscan (1M) or lanadmin(1M) commands.
Table 7-2 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. |
The EMS product depends on TCP/IP (or UDP) to send events to targets such as HP OpenView
IT/Operations or MC/ServiceGuard. 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.
