Protocol Field

For the logical interface, the Protocol field indicates the protocol family or families that are configured on the interface, displaying one or more of the following values:

• aenet—Aggregated Ethernet. Displayed on Fast Ethernet interfaces that are part of an aggregated Ethernet bundle.
• ccc—Circuit cross-connect (CCC). Configured on the logical interface of CCC physical interfaces.
• inet—IP version 4 (IPv4). Configured on the logical interface for IPv4 protocol traffic, including Open Shortest Path First (OSPF), Border Gateway Protocol (BGP), Internet Control Message Protocol (ICMP), and Internet Protocol Control Protocol (IPCP).
• inet6—IP version 6 (IPv6). Configured on the logical interface for IPv6 protocol traffic, including Routing Information Protocol for IPv6 (RIPng), Intermediate System-to-Intermediate System (IS-IS), and BGP.
• iso—International Organization for Standardization (ISO). Configured on the logical interface for IS-IS traffic.
• mlfr-uni-nni—Multilink Frame Relay (MLFR) FRF.16 user-to-network network-to-network (UNI NNI). Configured on the logical interface for link services bundling.
• mlfr-end-to-end—Multilink Frame Relay end-to-end. Configured on the logical interface for multilink bundling.
• mlppp—MLPPP. Configured on the logical interface for multilink bundling.
• mpls—Multiprotocol Label Switching (MPLS). Configured on the logical interface for participation in an MPLS path.
• tcc—Translational cross-connect (TCC). Configured on the logical interface of TCC physical interfaces.
• tnp—Trivial Network Protocol. Used to communicate between the Routing Engine and the routing platform's packet forwarding components. The JUNOS software automatically configures this protocol family on the routing platform's internal interfaces only.
• vpls—Virtual private LAN service (VPLS). Configured on the logical interface on which you configure VPLS.
