Configuring Token Ring Services

117020-A Rev. A 4-3

You can set the source for MAC addresses on a token ring interface to

• BOXWIDE -- The interface uses a MAC address that the software generates

from the router’s serial number.

• PROM -- The interface uses a MAC address from the PROM on the Token

Ring link module.

• CNFG -- You explicitly assign a MAC address with the MAC Address

Override parameter.

Specifying the Ring Speed

You can set the ring speed for a token ring interface to 4 or 16 Mb/s. By default,

the ring speed is 16 Mb/s.

If you use 16 Mb/s, the router enables the Early Token Release protocol, which is

used extensively on 16-Mb/s media. In the unlikely event that you want to disable

Early Token Release over 16-Mb/s token ring media, disable Early Token Release

as described in the next section.

Enabling or Disabling Early Token Release

Early token release indicates that the token can return to the ring before the

recipient copies all data. By default, Site Manager enables early token release on

an interface.

You can disable or enable early token release on an interface only when the Ring

Speed is16 Mb/s.
