Configuration Commands
hi-bw-mcast-src
Syntax hi-bw-mcast-src [alarm] [group group-id]
no hi-bw-mcast-src
Context config>card>mda
Description This command designates the MDA as a high-bandwidth IP multicast source, expecting the ingress
traffic to include high-bandwidth IP multicast traffic. When configured, the system attempts to
allocate a dedicated multicast switch fabric plane (MSFP) to the MDA. If a group is specified, all
MDAs in the group will share the same MSFP. If the alarm parameter is specified and the system
cannot allocate a dedicated MSFP to the new group or MDA, the MDAs will be brought online and
generate an event (SYSTEM: 2052 - mdaHiBwMulticastAlarm). Similarly, if during normal
operation there is a failure or removal of resources, an event will be generated if the system cannot
maintain separation of MSFPs for the MDAs.
This feature is supported on the 7750 SR-7 and 7750 SR-12.
The no form of the command removes the high-bandwidth IP multicast source designation from the
MDA.
Default
no hi-bw-mcast-src

group-id will be placed on the same MSFP.
Values
0 — 32 (A value of 0 removes the MDA from the group.)
Default
By default, "none" is used, and the system will attempt to assign a unique MSFP to
the MDA.
