Junos OS 12.1 Interfaces Command Reference
128
• Primary—Interface can be considered for selection as the primary family address.
• Protocol-Down—Protocol failed to negotiate correctly.
• SCU-in—Interface is configured for source class usage input.
• SCU-out—Interface is configured for source class usage output.
• send-bcast-packet-to-re—Interface is configured to forward IPv4 broadcast packets
to the Routing Engine.
• targeted-broadcast—Interface is configured to forward IPv4 broadcast packets to the
LAN interface and the Routing Engine.
• Unnumbered—Protocol family is configured for unnumbered Ethernet. An unnumbered
Ethernet interface borrows an IPv4 address from another interface, which is referred
to as the donor interface.
• Up–Protocol is configured and operational.
• uRPF—Unicast Reverse Path Forwarding is enabled.
Interface Flags Field
The Interface flags field provides information about the physical interface and displays
one or more of the following values:
• Admin-Test—Interface is in test mode and some sanity checking, such as loop detection,
is disabled.
• Disabled—Interface is administratively disabled.
• Down—A hardware failure has occurred.
• Hardware-Down—Interface is nonfunctional or incorrectly connected.
• Link-Layer-Down—Interface keepalives have indicated that the link is incomplete.
• No-Multicast—Interface does not support multicast traffic.
• No-receive No-transmit—Passive monitor mode is configured on the interface.
• Point-To-Point—Interface is point-to-point.
• Pop all MPLS labels from packets of depth—MPLS labels are removed as packets arrive
on an interface that has the pop-all-labels statement configured. The depth value can
be one of the following:
• 1—Takes effect for incoming packets with one label only.
• 2—Takes effect for incoming packets with two labels only.
• [ 1 2 ]—Takes effect for incoming packets with either one or two labels.
• Promiscuous—Interface is in promiscuous mode and recognizes frames addressed to
all physical addresses.
• Recv-All-Multicasts—Interface is in multicast promiscuous mode and provides no
multicast filtering.
