Juniper SYSTEM BASICS - CONFIGURATION GUIDE V 11.1.X

For example a PPP interface configured on top of an ATM interfaces is:
■ PPP3/0.1—Proprietary method
■ ATM3/0.1—Industry method
snmp-server interfaces description-format
Use to set the encoding scheme of the ifDescr and ifName objects. Include one
of the following keywords:
■
■ common—Sets the encoding scheme to the conventional industry method
and provides compatibility with software that uses the industry encoding
scheme.
■ legacy—Sets the encoding scheme for legacy E Series routers.
■ proprietary—Sets the encoding scheme to the E Series router proprietary
method.
■ Example
host1(config)#snmp-server interfaces description-format common
■ Use the no version to return to the default, the legacy encoding scheme.

Managing Interface Sublayers
You can set up the SNMP agent to compress the number of interface instances in
the standard interface and stack tables. You can also control the interface numbering
method used in the interface tables.
Compressing Interfaces
You can compress interfaces by interface type, table type, and the administrative
status of the interface.
Compressing interfaces without specifying a table type removes them from the
interface tables (ifTable, ifXTable, and juniIfTable), the interface stack tables
(ifStackTable, ifInvStackTable, and juniIfInvStackTable), the ipAddrTable, and the
ipNetToMedia table, which increases table retrieval performance. For example, if
you want statistics kept only on IP interfaces, then you can compress all interfaces
except IP; subsequently, only IP interfaces will appear in the interface tables, interface
stack tables, ipAddrTable, and ipNetToMedia table.
Compressing a table type in an interface removes the interface from the specified
table type. For example, if you want to compress an interface only in interface tables,
you can specify the table-type keyword and interface-tables as the TableType value.
To compress interfaces that have an administrative status of down, use the
snmp-server interfaces compress-restriction command.
