SignificanceDefinitionFabric Bandwidth
If is also a calculated value as a
function of user-defined threshold
and denotes a lower cut-off for
disabling network interfaces on line
card.
Disabling happens when “Available
bandwidth” falls below the “Lower
required bandwidth”.
Total fabric bandwidth x
(Bandwidth Threshold - 10%)
This computation is applicable only
for bandwidth threshold values
20% or higher.
For bandwidth threshold values of
below 20%, the “Lower required
bandwidth” is equal to “Total
required bandwidth”.
Lower required bandwidth
The Bandwidth Threshold acts a check point to ensure substantial bandwidth availability to carry traffic to
the fabric cards. To configure the bandwidth threshold, use the following commands:
Router# configure
Router (config)# hw-module profile bw-threshold <value>
Router (config)# commit
User can set the threshold value starting with 10 and in increments of 10.
For example, consider that the bandwidth threshold is set to 20%. If the available bandwidth goes below 10%,
then the network interfaces of the line card are shut. If the available bandwidth goes above 20%, then the
network interfaces of the line card are unshut. The following table provides threshold references.
