Table 4-4Troubleshooting the Token Ring Connection (Models 327 and 527 only) (continued)

Symptom Cause and Action

The MAC address of the system does not appear on the token ring network.

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)
						is converted to
10	00	40	58	D2	3A	noncanonical (most significant bit first)
	1A		=		58
0001 1010				0101 1000

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.
