Description: Manages multicast group forwarding and replication on Askey broadband access equipment.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is ASKEY-MCAST-MIB?

ASKEY-MCAST-MIB is an Askey enterprise MIB for managing multicast group forwarding and replication on Askey broadband access equipment, such as DSL or cable customer-premises/access gateways. Its module description details a per-port profile bitmap scheme, where each bit represents whether a given multicast profile (e.g., a channel or service group) is enabled for replication on that port. This is software/service-level monitoring for multicast delivery: it lets an operator confirm which multicast profiles (commonly IPTV channel groups) are enabled per subscriber port, which is essential for diagnosing a subscriber not receiving an expected multicast stream or unauthorized profiles being forwarded. It likely complements standard IGMP-related multicast management concepts, implemented instead as an Askey-private enterprise extension tailored to broadband access hardware. It is deployed on Askey broadband access equipment used by ISPs delivering multicast-based IPTV or similar triple-play services to subscribers, with the ASKEY-MCAST-MIB MIB providing the per-port profile bitmap objects needed for that visibility.

IPNetwork Monitor allows you to monitor SNMP objects defined in ASKEY-MCAST-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Monitoring Examples

No specific object or table names were provided beyond the bitmap-based profile scheme described in the module text; conceptually, an administrator would decode the per-port profile bitmap (each octet covering eight profiles) to confirm which multicast/IPTV profiles are enabled on a given subscriber port, revealing a missing or incorrectly disabled profile bit as the cause of a subscriber not receiving an expected channel.

What Can Be Monitored

per-port multicast profile enablement bitmap
multicast forwarding/replication status per port
IPTV channel/profile assignment per port

OIDs

OID symbolic	OID numeric	Type	Access	Description
askeyMcastMib	1.3.6.1.4.1.3646.1300.2.5			ASKEY MULTICAST PROFILE MIB OID defines and documentation.

INT mcastProfileCount	1.3.6.1.4.1.3646.1300.2.5.1.1	INTEGER	read-only	This object respresents the total count of configured multicast profiles.
mcastProfileTable	1.3.6.1.4.1.3646.1300.2.5.1.2		not-accessible	This table contains information on the ADSL line configuration. One entry in this table reflects a profile defined by a manager which can be used to configure the ADSL line.
mcastProfileEntry	1.3.6.1.4.1.3646.1300.2.5.1.2.1		not-accessible	Each entry consists of a list of parameters that represents the configuration of an multicast group.
INT mProfileId	1.3.6.1.4.1.3646.1300.2.5.1.2.1.1	INTEGER	read-only	The unique sequential number for each profile entry, starting from 1 and end with 256, which is referenced one by one by mConfigProfileBitMap(256 bits) in mcastConfigLineEoaTable
STR mProfileName	1.3.6.1.4.1.3646.1300.2.5.1.2.1.2	SnmpAdminString	read-create	This object is used by the multicast configuration table in order to give a row of this table a specific name which is unique. For example: ESPN, HBO...etc.
IP mProfileIpAddr	1.3.6.1.4.1.3646.1300.2.5.1.2.1.3	IpAddress	read-create	The IP address of the multicast stream.
INT mProfileRate	1.3.6.1.4.1.3646.1300.2.5.1.2.1.4	INTEGER	read-create	The maximum transmit data rate in Kbps applied to this multicast stream The specified data rate will be rounded to the largest multiple of 32.
INT mProfilePriority	1.3.6.1.4.1.3646.1300.2.5.1.2.1.5	INTEGER	read-create	The transmit priority applied to this multicast stream The value 0 indicateds the lowest priority, the value 3 indicateds the highest priority
ROW mProfileRowStatus	1.3.6.1.4.1.3646.1300.2.5.1.2.1.6	RowStatus	read-create	This object is used to create a new row or modify or delete an existing row in this table. A profile activated by setting this object to `active'. When `active' is set, the system will validate the profile. Before a profile can be deleted or taken out of service, (by setting this object to `destroy' or `outOfService') it must be first unreferenced from all associated lines. If the implementator of this MIB has chosen not to implement `dynamic assignment' of profiles, this object's MIN-ACCESS is read-only and its value is always to be `active'.
mcastConfigLineEoaTable	1.3.6.1.4.1.3646.1300.2.5.2		not-accessible	This table contains information on the ADSL line configuration. One entry in this table reflects a profile defined by a manager which can be used to configure the ADSL line.
