Parameter: Last Hop Threshold
Path: Configuration Manager > Protocols > IP > PIM > Global
Default: Enable
Options: Enable
|
Disable
Function: Indicates whether the last-hop router switches from the shared tree to a
source-specific, shortest-path tree. The last-hop router sets up a shortest-path
tree when the data rate for the group exceeds the configured traffic threshold
rate specified using the Last Hop Data Threshold parameter.
Instructions: Set to Enable if you want the last-hop router to switch from a shared tree to a
shortest-path tree to the source of that data. Set to Disable to prevent the
last-hop router from switching to the shortest-path tree, regardless of the traffic
rate specified using the Last Hop Data Threshold parameter.
MIB Object ID: 1.3.6.1.4.1.18.3.5.3.14.1.9
Parameter: Last Hop Data Threshold
Path: Configuration Manager > Protocols > IP > PIM > Global
Default: 2048
Options: 0 to 65,535 (bytes per second)
Function: Specifies the rate, in bytes per second, at which the last-hop router receives data
from the source. If the data rate exceeds the threshold configured on the last-hop
router, the last-hop router switches to a shortest-path tree.
Instructions: Specify a data rate threshold from 0 through 64 to enable the last-hop router to
immediately switch to the shortest-path tree upon receiving the first packet from
the source. Otherwise, the data rate is averaged over the threshold sample
interval and the switch is made based on this average.
