Table 29. Token-Ring 4/16 Valid Packet Sizes
Network Data
Speed	Values (# of bytes)
4 Mbps	516 to 4498
	Note: If a value greater than 4498 is de®ned for a 4 Mb TR then the
	software will set it to 4498. If the user does not specify a value, then the
	default is 2052.
16 Mbps	516 to 18144
	Note: If you do not specify a value, then the default is 2052.

Note: If packet sizes are increased, buffer memory requirements will also increase.

Set

Use the set command to set the Routing Information Field (RIF) timer and the physical (MAC) address.

Syntax:
set	physical-address
	rif-timer

physical-address

Indicates whether you want to de®ne a locally administered address for the Token-Ring interface's MAC sublayer address, or use the default factory station address (indicated by all zeroes). The MAC sublayer address is the address that the Token-Ring interface uses to receive and transmit frames.

Note: Pressing Return leaves the value the same. Entering 0 and pressing Return causes the router to use the factory station address. The default is to use the factory station address.

Valid values: Any 12-digit hexadecimal address.

Default value: burned-in address (indicated by all zeroes).

Example:

set physical-address

MAC address in 00:00:00:00:00:00 form []?

rif-timer

Sets the maximum amount of time (in seconds) that the information in the

RIF is maintained before it is refreshed. The default is 120.

Example:

set rif-timer

RIF aging timer value [120]? 120

Source-routing

Use the source-routingcommand to enable or disable end station source routing. Source routing is the process by which end stations determine the source route to use to cross source routing bridges. Source routing allows the IP, IPX, and AppleTalk Phase 2 protocols to reach nodes on the other side of the source routing bridge.
