hcxVlanMcastDnstrmRate
Module: COM21-HCXVLAN-MIB
OID (symbolic): COM21-HCXVLAN-MIB::hcxVlanMcastDnstrmRate
OID (numeric): 1.3.6.1.4.1.1141.2.81.1.1.11
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Specifies the downstream multicast rate associated with this Vlan. Defined in bits per second. The multicast rate is ondemand (not guaranteed if enough bandwidth is not available). 0 stops all broadcast forwarding. Default 100000. If a twoWay modem of model CP1000, CP1000A, CP1000B or CP1000C is acquired in the system or a teleRet modem is configured then the multicast rate will be dynamically lowered to not exceed 1000000. Under that condition an attempt to set the rate to greater than 1000000 will be rejected. The rate wil remain at 1000000 even if the condition clears eventually (all the modems of model CP1000, CP1000A, CP1000B or CP1000C get deacquired and no more teleRet modems are configured).
What is hcxVlanMcastDnstrmRate?
This read-write integer (0-10000000 bps), defaulting to 100000, caps the on-demand (not guaranteed) downstream multicast rate for this VLAN, with 0 stopping all broadcast forwarding, and the description notes special handling for CP1000-series and telephone-return modems. An admin uses this to prevent multicast or broadcast traffic, such as video, from overwhelming the VLAN's downstream capacity. For example, an admin raises hcxVlanMcastDnstrmRate above the 100000 bps default to accommodate a new IPTV multicast stream that was exceeding the cap.
