LINKCONTROL Command
NS 3000/iX 100Base-T Link Statistics
media. The default station address is used unless it is overridden in the
NMMGR link configuration screen. If this field is changed, then the
station address of this node is changed. Make sure that you note this
new address in the system manager log.
Default Station Address — The Default Station Address field is the
default value for the Current Station Address described above. The
default station address is determined by the specific adapter card. On
HP-PB systems, it is also printed on a small label attached to a circuit
board on the adapter card.
NOTE
This printed label is not available for PCI adapter cards. If the adapter
card is changed for any reason, the Default Station Address of this node
will change.
Current Multicast Address List — The Current Multicast Addresses
field contains a list of all multicast addresses to which the adapter card
responds. The default multicast address list contains no addresses. If
no multicast addresses are enabled, the follow message is printed:
Current multicast address list is empty
Multicast addresses are configured automatically by the network
transport(s) using the adapter card. For PCI 100BT links, the
maximum number of multicast addresses currently allowed is 14 (this
is due to an implementation decision regarding how the PCI 100BT
card manages multicast addresses). An example of multicast addresses
are:
09-00-09-00-00-01 Probe address
09-00-09-00-00-02 Second probe address
09-00-09-00-00-04 DTC boot address
STATISTICS Parameter Fields
The
STATISTICS
parameter for 100Base-T links displays many fields in
addition to the
LINKSTATE
parameter fields. The
CONFIGURATION
parameter fields are not displayed when this parameter is used. For an
example of the data that is displayed when you issue the LINKCONTROL
linkname
