fddi path maxTreq
Specifies the maximum time value (in microseconds) of fddiMACT-Req
that is used by any MAC that is configured in this path. T-Req is the value
that a MAC bids during the claim process to determine a ring’s
operational token rotation time, T_Opr. The lowest T-Req bid on the ring
becomes T_Opr.
Valid Minimum Abbreviation
fd pa m
Important Considerations
■
When you set T_Opr low, the token rotates more quickly, so token
latency is reduced. However, more of the ring’s available bandwidth is
used to circulate the token.
■
Higher values of T_Opr use less bandwidth to circulate the token, but
they increase token latency when the ring is saturated.
■
You can use this command to configure the same setting on multiple
ports simultaneously. When you specify multiple port numbers, the
system prompts you to choose the setting and then applies it to all of
the ports.
