Service Egress and Ingress QoS Policies
Quality of Service Guide 385
subscriber subscriber-id — The subscriber keyword is used to specify that the system should
find and display the BCG and calculate the slowest accurate visitation time for the queues
associated with the specified subscriber-id. The queue-group keyword is mutually exclusive
with the other from match criteria. If the specified subscriber-id does not exist, the system
should return ‘The specified subscriber does not exist’. This parameter applies to the
7450 ESS and 7750 SR only.
network {mda-id | port-id} — The network keyword is used to specify that the system should
find and display the queue information for the queues associated with the specified mda-id or
port-id. If the ingress direction qualifier is specified, an mda-id is required. If the egress
direction qualifier is specified, a port-id is required. The network keyword is mutually
exclusive with the other from match criteria. If the specified mda-id does not exist, the system
should return ‘The specified XMA or MDA is not provisioned’. If the specified port-id does
not exist, the system should return ‘The specified port is not provisioned’.
system {card slot-number | mda-id | port-id} — The system keyword is used to specify that the
system should find and display the queue information for all the system queues associated
with the specified card slot-id, mda mda-id or port port-id. If the ingress direction qualifier is
specified, the ingress system queues are displayed. If the egress direction qualifier is
specified, only the egress system queues are displayed. The system keyword is mutually
exclusive with the other from match criteria. If the specified slot-id does not exist, the system
should return ‘The specified slot number is not provisioned’. If the specified mda-id does not
exist, the system should return ‘The specified MDA is not provisioned’. If the specified port-
id does not exist, the system should return ‘The specified port is not provisioned’. The id
parameter is not supported when matching system queues.
{ingress | egress} — The ingress and egress direction qualifiers are mutually exclusive. Either
ingress or egress must be specified.
id queue-id — The id keyword is used to limit the return queues to a single queue-id. The
keyword is not accepted when the system match criteria is used.

Description The show qos bcg command outputs the current and historical visitation time associated with the
specified BCG name.
A Burst Control Group (BCG) represents a list of queues that share the same non-scheduling PIR and
CIR bucket target update interval. When a queue’s scheduled rate bursts above its PIR bucket depth,
the queue is removed from its scheduling context. The system uses a BCG in order to visit the queues
PIR bucket to periodically drain an appropriate amount from the bucket. When the bucket has been
drained below the PIR bucket threshold, the queue is allowed back onto its scheduling context. The
