Configuring OSS Mapping
Configuring OSS Mapping to Represent a T4000 Chassis as a T1600 or a T640 Chassis
You can configure the operations support systems (OSS) mapping feature to represent a T4000 chassis as a T1600 chassis or a T640 chassis. This topic includes the following tasks:
- Configuring T4000 Chassis as a T1600 Chassis
- Configuring T4000 Chassis as a T640 Chassis
- Disabling the OSS Mapping Feature
Configuring T4000 Chassis as a T1600 Chassis
To configure a T4000 chassis as a T1600 chassis:
Configuring T4000 Chassis as a T640 Chassis
To configure a T4000 chassis as a T640 chassis:
By default, the OSS mapping feature is disabled.
Disabling the OSS Mapping Feature
To disable the OSS mapping feature:
The
set chassis oss-map model-name t640 | t1600command is applicable only on T4000 routers. You must explicitly set this command when a T1600 chassis or a T640 chassis is upgraded to a T4000 chassis.You can execute the
set chassis oss-map model-name t640command or theset chassis oss-map model-name t1600command if the OSS is compatible with either the T640 chassis or the T1600 chassis, respectively.
Example: Configuring a T4000 Chassis to Represent a T640 Chassis
This example shows how to configure OSS mapping feature to represent a T4000 chassis as a T640 chassis. You can extend this concept to configure a T4000 chassis to represent as a T1600 chassis as well.
Requirements
This example uses the following hardware and software components:
One T4000 router
Junos OS Release 12.3R3, 13.1R2, 13.2R1, or later
Overview
Operations support systems (OSS) is used by service providers to maintain their networks. When a new router is added or removed from the network, the OSS must be updated to reflect the changes. This process is tedious and time-consuming.
When a T1600 chassis or a T640 chassis is upgraded to a T4000 chassis, the OSS identifies the new chassis as a new networking element and follows a tedious process of qualifying it for the customer’s network. The OSS mapping feature helps avoid this scenario.
Using the OSS mapping feature, you can map a T4000 chassis to
a T1600 chassis or to a T640 chassis with the set chassis oss-map
model-name t640|t1600 configuration command. This configuration
command overrides the chassis model name, so that the OSS recognizes
the chassis as a known chassis and proceeds without any requalification.
The
set chassis oss-map model-name t640 | t1600command is applicable only on T4000 routers. You must explicitly set this command when a T1600 chassis or a T640 chassis is upgraded to a T4000 chassis.You can execute the
set chassis oss-map model-name t640command or theset chassis oss-map model-name t1600command, if the OSS is compatible with either the T640 chassis or the T1600 chassis, respectively.
Configuring the T4000 Chassis to Represent a T640 Chassis
Procedure
Step-by-Step Procedure
To configure the T4000 chassis to represent a T640 chassis by using the OSS mapping feature:
In configuration mode, go to the
[edit chassis]hierarchy level.[edit] user@T4000# edit chassis
Configure the OSS mapping feature to map the T4000 chassis to a T640 chassis.
[edit chassis] user@T4000# set oss-map model-name t640
Verification
Verifying the OSS Mapping Feature
Purpose
To verify that the OSS mapping feature is working on a T4000 router.
Action
Run the show chassis operational command and verify that the configured known chassis name is displayed when the T4000 chassis is mapped to a T640 chassis.

Verifying the OSS Mapping Feature on SNMP MIBs
Purpose
To verify that the SNMP MIBs are updated with the configured known chassis name.
Action
Run the show snmp mib operational commands
and verify that the configured known chassis name is displayed in
SNMP MIBs when the T4000 chassis is mapped to a T640 chassis:
Run the
show snmp mib walk systemoperational command:show snmp mib walk system
user@T4000> show snmp mib walk system sysDescr.0 = Juniper Networks, Inc. t640 internet router, kernel JUNOS 12.3-...Juniper Networks, Inc. sysObjectID.0 = jnxProductNameT640 ...
Run the
show snmp mib walk jnxBoxAnatomyoperational command:show snmp mib walk jnxBoxAnatomy

Meaning
On configuring the OSS mapping feature, the OSS maps the T4000 chassis to a T640 chassis, thereby preventing requalification of the new chassis.
