JUNIPER-ATM-COS-MIB
Updated Apr 9, 2003AI MIB Summary
The JUNIPER-ATM-COS-MIB enables monitoring and management of Class of Service (CoS) parameters, including Random Early Detection (RED) and Packet Loss Priority (PLP) settings, on Juniper devices supporting Asynchronous Transfer Mode (ATM) interfaces. This module provides access to specific traffic classification, queuing, and dropping statistics required for enforcing quality of service policies across ATM infrastructure.
The Juniper enterprise MIB for ATM COS (Class Of Service) infrastructure. For detailed information on ATM COS, Junos Documentation is recommended as the reference.

reference.

jnxCosAtmVcTableA table of ATM VCs which have COS configured. SEQUENCE OF JnxCosAtmVcEntry .1.3.6.1.4.1.2636.3.21.1 |
jnxCosAtmVcEntryThis entry contains COS info specific to an ATM VC.
Each entry is indexed using ifIndex, vpi and vci of
the VC. JnxCosAtmVcEntry .1.3.6.1.4.1.2636.3.21.1.1 |
jnxCosAtmVcCosModeThe mode of COS queue priority for the VC.
strict mode :
One queue of the four queues has strict high priority and
is always serviced before the rest of the queues. The
remaining queues are serviced in round robin fashion.
alternate mode :
One queue has high priority, but the servicing of the
queues alternates between the high priority queue and the
rest of the queues.ro Enumeration .1.3.6.1.4.1.2636.3.21.1.1.1 |
jnxCosAtmVcScTableA table of rows representing atm-scheduler config
parameters for each forwarding class within a specified VC.
NOTE: These schedulers are specific to an atm interface and
are different from the typical schedulers specified under
class-of-service config in CLI. Hence, hereafter, through
out this mib, scheduler will be referred to as atm-scheduler
to avoid any confusion. SEQUENCE OF JnxCosAtmVcScEntry .1.3.6.1.4.1.2636.3.21.2 |

forwarding class and per VC. JnxCosAtmVcScEntry .1.3.6.1.4.1.2636.3.21.2.1 |

jnxCosAtmVcScDpTypeThe type of RED drop profile configured for the specified
forwarding class within the specified VC. A scheduler can
specify either linear or constant drop profile.

cells should be dropped. Whereas a linear type drop profile
specifies that only a percentage of cells be dropped based
on the number of queued cells at any time.ro Enumeration .1.3.6.1.4.1.2636.3.21.2.1.4 |
