Table 4-4 Troubleshooting the Token Ring Connection (Models 327 and 527 only) (continued)
Symptom
The MAC address of the system does
not appear on the token ring network.
Cause and Action
The MAC address on the network is in noncanonical format.
The MAC address encoded on the EEPROM and printed on the label
is in canonical format and needs to be converted to noncanonical
format. Each byte, represented by the number pairs below, consists
of 8 bits. To convert the canonical byte 1A (in hexadecimal) to the
noncanonical byte, you must mirror the bits, as shown.
08 00 02 1A 4B 5C canonical (least significant bit first)
10 00 40 58 D2 3A noncanonical (most significant bit first)
1A
0001 1010
The MacAddrConvert command converts a MAC address in
canonical format to noncanonical format. For example, if you enter:
MacAddrConvert 0800021A4B5C
The system displays the following:
%10004058D23A
If you experience a problem or receive an error message that is not
documented in Table 4-4, contact your network supplier.
