DGS-3630 Layer 3 Stackable Managed Switch CLI Reference Guide Command Mode Global Configuration Mode. Command Default Level Level: 12. Usage Guideline When the DR receives multicast stream, it will send register message to the RP of the group. And when the RP receives this message, it would set up a timer for this (S, G) entry. This command configures the value of this timer. Example This example shows how to configure the PIM register keep-alive time to 500 seconds. Switch# configure terminal Switch(config)# ip pim rp-register-kat 500 Switch(config)# 96-14 ip pim spt-threshold This command is used to configure the condition to switch over to the source tree. Use the no form of this command to revert to the default setting. ip pim spt-threshold {0 | infinity} no ip pim spt-threshold Parameters 0 infinity Specifies to establish the source tree right at the arrival of the first packet. Specifies to always rely on the shared tree. Default By default, this option is infinity. Command Mode Global Configuration Mode. Command Default Level Level: 12. Usage Guideline Use this command on the last hop of the router. In the PIM-SM mode, initially the multicast traffic from the source will be flowing along the RPT share tree to the receiver. After the first packet arrives at the last hop router, for each group of traffic, it can operate in one of the following two modes. With the mode infinity, the traffic keeps following the share tree. With the mode 0, the source tree will be established and the traffic switchover to the source tree. 1260
