HP 12076A LAN/1000 LINK RC Command Examples

RC Command Examples

Here are examples of using the Read Link Configuration (RC) command.

Example 1. Using RC Command Defaults

NM> RC<RETURN>
Read 802.3 Link Config from node		08-00-09-00-02-5A....
Station Address	08-00-09-00-02-5A
Downloading Server Address	08-00-09-00-03-85
File Server Station Address	08-00-09-00-03-85
Receive Packet Filter	06
Retry Limit	0F
Save Bad Packet Flag	01
Extended Trace Mode Flag	00

NM>

Example 1 shows a listing returned when all command parameters are defaulted. (The same listing would be returned if RC,,A<RETURN> was entered).

In this case ADR defaulted to 08"00"09"00"02"5A hex, which is the Station Address of the LANIC card with the lowest LU. Because the PAR# parameter defaults to •A", the values associated with PAR# entries 1, 4, 5, 6, 7, 9, and 10 are returned.

Because the parameters ADR and LU# refer to the same card, the Station Address indicated is the same as that of the target node. The Downloading Server Address is the Download Server Station Address stored on the card (RAM). The File Server Station Address represents the node where the Link File directory for the target node is maintained.

Since the Receive Packet Filter setting is 06, this node receives Individual Multicast, and Broadcast messages (see Table 5"4). Since the Retry Limit is 0F hex (decimal 15), this node will try to transmit a packet up to 16 times (initial attempt plus 15 Retries) until successful.

The Save Bad Packet Flag is set, so this node will save invalid IEEE 802.3 packets for passing to Node Manager software. The Trace Mode Flag has not been set, so unsuccessful packet transmissions are not returned to Node Manager software.

Example 2. Displaying a Node's Multicast Address List

NM> RC,08-00-09-00-02-5A,2<RETURN>
Read 802.3 Link Config from node		08-00-09-00-02-5A....
Multicast Address List
09-00-09-10-0A-5C	FF-FF-FF-FF-FF-09		FF-FF-FF-FF-FF-0E
FF-FF-FF-FF-FF-10	FF-FF-FF-FF-FF-12

NM>

In Example 2, an ADR parameter is specified and represents the target node's Station Address. Note that hyphens (-) are required between each pair of hexadecimal digits of the address when entering the command. Also, PAR# is specified as 2 to display the node's Multicast Address List configured on the card.
