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 defined fora4MbTRthen 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 define 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-routing command 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.
