Statement introduced before Junos OS Release 7.4.
Statement introduced in Junos OS Release 9.0 for EX Series switches.
Configure an informational-only bandwidth value for an interface. This statement is valid
for all logical interface types except multilink and aggregated interfaces.
NOTE: We recommend that you be careful when setting this value. Any
interface bandwidth value that you configure using the
affects how the interface cost is calculated for a dynamic routing protocol,
such as OSPF. By default, the interface cost for a dynamic routing protocol
is calculated using the following formula:
cost = reference-bandwidth/bandwidth,
where bandwidth is the physical interface speed. However, if you specify a
value for bandwidth using the
calculate the interface cost, rather than the actual physical interface
bandwidth.
rate —Peak rate, in bits per second (bps) or cells per second (cps). You can specify a
value in bits per second either as a complete decimal number or as a decimal number
followed by the abbreviation
can also specify a value in cells per second by entering a decimal number followed
by the abbreviation c ; values expressed in cells per second are converted to bits per
second by means of the formula 1 cps = 384 bps.
Range: Not limited.
