About Bay Networks Token Ring Media

Token ring is a 4- or 16-Mb/s token-passing, baseband LAN that operates in a ring

topology that conforms to the IEEE 802.5 standard. It is compatible with

IEEE 802.2 Type 1 (connectionless) and Type 2 (connection-oriented) support.

A token ring LAN uses shielded or unshielded twisted pair cable; the interface

supports IBM Type 1 and Type 3 cabling.

Enabling or Disabling a Token Ring Interface

The router enables token ring line services when you add the circuit. You can

disable and enable the interface without moving physical cabling.

Specifying a MAC Address Override

To specify a MAC address for an interface (for example, to avoid host number

conﬂicts on a directly connected IPX or XNS network), use this parameter to enter

the 48-bit MAC address in MSB format; that is, enter 0x followed by 12

hexadecimal digits.

If you want the router to generate the MAC address for this token ring interface,

do not change this parameter from its default value of zero.

If you enter a MAC address with this parameter, you must set the MAC Address

Source to CNFG, as described in the next section.

Specifying a MAC Address Source

By default, the token ring interface uses the MAC address stored in the

programmable read-only memory (PROM) on the link module.
