Configuring Encoding Method

You can control how the router encodes the ifDescr and ifName objects in the SNMP agent’s interface table and in the bulkstats application.

There are two choices of encoding schemes: an E-series router proprietary method and a conventional industry method.

• The proprietary method identifies each interface sublayer with its type.
• The industry method bases the type information for each interface sublayer on the lowest layer 1 or layer 2 interface type.

For example a PPP interface configured on top of an ATM interfaces is:

• PPP3/0.1—Proprietary method
• ATM3/0.1—Industry method

• 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.
