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 for-
warding plane.
Default no hi-bw-mcast-src
Parameters alarm — Enables event generation if the MDA is required to share an MSFP with another MDA that is in a
different group. MDAs within the same group sharing an MSFP will not cause this alarm.
group group-id — Specifies the logical MSFP group for the MDA. MDAs configured with the same 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.
default-paths-only — When this parameter is specified the system will only attempt to allocate the two
default paths (one high priority and one low priority) to dedicated MSFPs.
shutdown
Syntax [no] shutdown
Context config>card>fp>egress>max-wred-control
Description This command enables or disables egress WRED queue support on the IOM. By default, WRED queue sup-
port is disabled (shutdown). While disabled, the various wred-queue-control commands may be executed on
the IOM and SAP egress QoS policies with wred-queue enabled may be applied to egress SAPs. The IOM
will allocate WRED pools to the WRED queues and the appropriate WRED mega-pool size and CBS
reserve size will be calculated, but the WRED mega-pool will be empty and all buffers will be allocated to
the default mega-pool. Each WRED queue will be mapped to either its appropriate default pool or an explic-
itly defined named pool.
Once the no shutdown command is executed, the calculated WRED mega-pool buffers will be moved from
the default mega-pool to the WRED mega-pool. The WRED mega-pool CBS reserve size will be applied
and each egress WRED queue will be moved from its default mega-pool buffer pool to its WRED pool
within the WRED mega-pool hierarchy.
The no form of the command enables WRED queuing on an egress IOM3-XP.
ingress
Syntax ingress
Context config>card>fp
Description The ingress CLI node within the fp node contains the multicast path management configuration commands
for IOM-3 ingress multicast management. The bandwidth-policy command is supported within the ingress
node.
