Description
This command configures WRED slopes within the WRED mega-pool. The WRED slopes in the WRED
mega-pool are used when WRED queues are requesting buffers from the mega-pool while they are over
their CBS threshold. Once over the CBS threshold, the WRED queue stops receiving buffers from the CBS
reserve in the mega-pool and starts competing for buffers in the shared portion of the mega-pool. If the
packet resulting in the buffer request is in-profile, the packet will be associated with the high priority slope.
Out-of-profile packets are associated with the low priority slope. While the queue is within its CBS thresh-
old, the slopes are ignored.
Within the defined slope-policy, each slope is enabled or disabled (no shutdown or shutdown) and each
slope's geometry is defined as percentages of shared portion depth.
The slope-policy also defines the time average factor (TAF) value that is used to determine how the pool's
weighted average depth is calculated. The higher the factor, the slower the average depth tracks the actual
pool depth.
The no form of the command restores the default slope policy to the WRED mega-pool.
Parameters
slope-policy-name — This required parameter specifies which slope policy the system should apply to the
WRED mega-pool. When slope-policy is not executed, the WRED mega-pool will use the default slope
policy. The defined slope policy must already exist or the command will fail.
Default
hi-bw-mcast-src
Syntax hi-bw-mcast-src [alarm] [group group-id] [default-paths-only]
no hi-bw-mcast-src
Context config>card>fp
Description This command designates the forwarding plane as a high-bandwidth IP multicast source, expecting the
ingress traffic to include high-bandwidth IP multicast traffic. When configured, the system attempts to allo-
cate a dedicated multicast switch fabric plane (MSFP) to the forwarding plane. If a group is specified, all
FPs in the group will share the same MSFP. If the alarm parameter is specified and the system cannot allo-
cate a dedicated MSFP to the new group or FP, the FPs will be brought online and generate an event (SYS-
TEM: 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.
