behind this PON port, only the first IGMP Join or the last IGMP Leave per multicast channel is tracked for
the purpose of the Vport bandwidth modification.
The Vport rate that will be affected by this functionality depends on the configuration:
•
•
The channel bandwidth definition policy is defined in the mcac policy in the configure>router>mcac>pol-
icy context. The policy is applied under the group-interface or in case of redirection under the redirected-
interface.
The rates in effect can be displayed with the following two commands:
show port 1/1/5 vport name
qos scheduler-hierarchy port port-id vport vport-name
The configuration of a scheduler policy under a VPORT, which is only applicable to Ethernet interfaces,
is mutually exclusive with the configuration of the egress-rate-modify parameter.
Context HQoS Adjustment for Vport is disabled.

Description
This command specifies the destination and organization strings to be used for matching subscriber hosts
with this Vport.
The parent Vport of a subscriber host queue, which has the port-parent option enabled, is determined by
matching the destination string dest string associated with the subscriber and the organization string org
string associated with the subscriber host with the strings defined under a Vport on the port associated with
the subscriber.
If a given subscriber host queue does not have the port-parent option enabled, it will be foster-parented to the
Vport used by this subscriber and which is based on matching the dest string and org string. If the subscriber
could not be matched with a Vport on the egress port, the host queue will not be bandwidth controlled and
will compete for bandwidth directly based on its own PIR and CIR parameters.
By default, a subscriber host queue with the port-parent option enabled is scheduled within the context of the
port's port scheduler policy.
Parameters description-string — The destination character string. Allowed values are any string up to 80 characters
long composed of printable, 7-bit ASCII characters. If the string contains special characters (#, $,
spaces, etc.), the entire string must be enclosed within double quotes.
7750 SR Interface Configuration Guide
In case the agg-rate within the Vport is configured, its value will be modified based on the IGMP
activity associated with the subscriber under this Vport.
In case the port-scheduler-policy within the Vport is referenced, the max-rate defined in the
corresponding port-scheduler-policy will be modified based on the IGMP activity associated with
the subscriber under this Vport.
