Abstract Data Type: octetArray ElementId: 104 Status: deprecated 5. Other Information Elements 5.1. Performance Metrics IEs ElementId: 65 .. 69 Performance metrics will need a consolidation in the industry, based on [RFC6390]. Once this consolidation happens, via a separate document the IEs 65-69 will either be assigned in the IANA registry or their status will be deprecated. 5.2. Application Information IEs ElementId: 94 .. 96 ElementId: 101 Please refer to [RFC6759]. 5.3. IEs Assigned for NetFlow v9 Compatibility ElementId: 105..127 These element IDs are not covered by this document and are left "as is", i.e., for NetFlow v9 compatibility. Yourtchenko, et al. Informational [Page 11] RFC 7270 Cisco Information Elements June 2014 6. IANA Considerations This document specifies several new IPFIX Information Elements in IANA’s "IPFIX Information Elements" registry [IANA-IPFIX] as summarized in Section 3 and detailed in Section 4 above.

Description of Cisco Systems' Subnet Allocation Option for DHCPv4
This memo documents a DHCPv4 option that currently exists and was previously privately defined for the operation and usage of the Cisco Systems’ Subnet Allocation Option for DHCPv4. The option is passed between the DHCPv4 Client and the DHCPv4 Server to request dynamic allocation of a subnet, give specifications of the subnet(s) allocated, and report usage statistics. This memo documents the cu...

The extensions defined in this document build on the RSVP Hello extensions defined in RFC 3209, and extensions for state recovery on nodal faults defined in RFC 3473. Using these extensions, the restarting node can recover all previously transmitted Path state, including the Explicit Route Object and the downstream (outgoing) interface identifiers. The extensions can also be used to recover sig...
