reset. Promiscuous mode and multicast addresses are preserved across the reset.
While the reset is in progress, the data traffic through the interface is interrupted. So, the command
automatically performs a Critical Resource Analysis to see if the interface is data-critical; that is, any
other resource depends for its functionality on the availability of the interface. If so, the reset is not
performed.
The reset can be forced, even if the interface is data-critical, by using the
--force option. It is pos-
sible for an interface to be system-critical; that is, the health of the system depends on the availability
of the interface. In that case, the reset is not be performed even if the
--force option is specified.
Reset Statistics of an Interface
The following command can be used to reset statistics for an interface.
nwmgr -r --st -c lan_instance
nwmgr --reset --stats --class_instance
lan_instance
The data traffic statistics for an interface are cleared to zero. This includes the byte count and packet
count for inbound and outbound traffic. Other aspects of the interface are left unmodified.
Diagnose Link Connectivity
The following command can be used to diagnose link connectivity.
nwmgr --diag [link] -A dest=mac_addr [--it number][-A pktsize=bytes]
[
-A timeout=seconds] -c lan_instance
nwmgr --diagnose [link] --attribute dest=mac_addr [--iterations number]
[--attribute pktsize=bytes][--attribute timeout=seconds]
--class_instance
lan_instance
Link connectivity at the data link layer is checked by sending IEEE XID test frames to the specified
destination MAC address and counting the replies.
The
--iterations option specifies how many test frames to send. The default value is 1.
The pktsize attribute specifies the size of each test frame. The default value is 100 bytes.
The timeout attribute specifies how many seconds to wait for the acknowledgement of each test
frame. The default value is 5 seconds.
RETURN VALUES
0 On success.
<>0 On failure, the command returns values in as shown in ERRORS below.
ERRORS
Below are the errors generated by nwmgr on failure.
[EACCES] Attempt to set a read-only attribute.
[EBUSY] The interface is currently inaccessible.
[EINVAL] One or more of the attributes or options is invalid for the operation.
[ENOMEM] Memory allocation failed. This could be a transient condition.
[ENOTSUP] Operation or feature is not supported.
[ENXIO] The target interface could not be accessed.
[EPERM] The user lacks the authorization "hpux.network.config", which is required for this
operation.
[ERANGE] The specified values of one or more attributes was less than the minimum or more
than the maximum.
EXAMPLES
List all LAN interfaces in the system.
nwmgr -C lan
Display the speed and MTU of the intl100 interface lan1.
