NETGEAR 8800 Chassis Switch CLI Manual Usage Guidelines Configuring a non-zero interval time can reduce the CPU load on the first hop switch, in case register stop messages are not received normally. When a non-zero value is configured, the first hop switch sends a few register messages and then waits for a corresponding register stop from the RP for seconds. The process is repeated until the register stop is received. This command should be used when the (S,G) tree between the first hop router and the RP is not converging quickly. The default value is zero in default mode, the switch sends continuous register messages until the register stop is received. Example The following command configures the initial PIM register rate limit interval: configure pim register-rate-limit-interval 2 configure pim register-suppress-interval register-probe-interval configure pim register-suppress-interval register-probe-interval Description Configures an interval for periodically sending null-registers. Syntax Description reg-interval probe-interval Specifies an interval time in seconds. Range is 30 - 200 seconds. Default is 60. Specifies an interval time in seconds. Default is 5. Default The following defaults apply: • register-suppress-interval-60 • register-probe-interval-5 Usage Guidelines The register-probe-interval time should be set less than the register-suppress-interval time. By default, a null register is sent every 55 seconds (register-suppress-interval register-probe-interval). A response to the null register is expected within register probe interval. By specifying a larger interval, a CPU peak load can be avoided because the null-registers are generated less frequently. The register probe time should be less than half of the register suppress time, for best results. Chapter 26. IP Multicast Commands | 1193
