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 5-1 “HA Network Interface Monitor Names and Resources” lists the HA Network Interface Monitor.
Table 5-1 HA Network Interface Monitor Names and Resources
| Monitor | Resource Type | Resource |
|---|
| lanmond | LAN Interface | /net/interfaces/lan/status/
<LANname> |
Figure 5-1 “Network
Monitor Resource Class Hierarchy” illustrates the
network monitored resources.
The MIB-2 variable, ifOperStatus, provides the LAN interface status to the monitor. For IPv6 enabled
systems, ipv6ifOperStatus, provides the LAN interface status to the monitor.
The monitor reports DOWN if it read the MIB value of TESTING. See Table 5-2 “Interpreting LAN Interface Status”.
To verify the operational status of the LAN interface, use the lanscan (1M) or lanadmin(1M) commands.
Table 5-2 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.
