Purpose
Command or Action
Configures the minimum and maximum automatic bandwidth set
on a tunnel.
bw-limit
{
min bandwidth
} {
max bandwidth
}
Example:
RP/0/RP0/CPU0:router(config-if-tunte-autobw)#
Step 5
min
Applies the minimum automatic bandwidth in kbps on a
tunnel. Range is from 0 to 4294967295.
bw-limit min 30 max 80
max
Applies the maximum automatic bandwidth in kbps on a
tunnel. Range is from 0 to 4294967295.
Configures the tunnel bandwidth change threshold to trigger an
adjustment.

Example:
RP/0/RP0/CPU0:router(config-if-tunte-autobw)#
Step 6
percentage
Bandwidth change percent threshold to trigger an adjustment
if the largest sample percentage is higher or lower than the
current tunnel bandwidth. Range is from 1 to 100 percent.
The default value is 5 percent.
adjustment-threshold 50 min 800
min
Configures the bandwidth change value to trigger an
adjustment. The tunnel bandwidth is changed only if the
largest sample is higher or lower than the current tunnel
bandwidth. Range is from 10 to 4294967295 kilobits per
second (kbps). The default value is 10 kbps.
Configures the tunnel overflow detection.

Step 7
percentage
Example:
RP/0/RP0/CPU0:router(config-if-tunte-autobw)#
Bandwidth change percent to trigger an overflow. Range is
from 1 to 100 percent.
overflow threshold 100 limit 1
limit
Configures the number of consecutive collection intervals
that exceeds the threshold. The bandwidth overflow triggers
an early tunnel bandwidth update. Range is from 1 to 10
collection periods. The default value is none.
min
Configures the bandwidth change value in kbps to trigger an
overflow. Range is from 10 to 4294967295. The default value
is 10.
