Device Flags

The Device flags field, which provides information about the physical device, displays one or more of the following values:

• Down—Device has been administratively disabled.
• Hear-Own-Xmit—Device receives its own transmissions.
• Link-Layer-Down—The link-layer protocol has failed to connect with the remote endpoint.
• Loopback—Device is in physical loopback.
• Loop-Detected—The link layer has received frames that it sent, thereby detecting a physical loopback.
• No-Carrier—On media that support carrier recognition, no carrier is currently detected.
• No-Multicast—Device does not support multicast traffic.
• Present—Device is physically present and recognized.
• Promiscuous—Device is in promiscuous mode and recognizes frames addressed to all physical addresses on the media.
• Quench—Transmission on the device is quenched, because the output buffer is overflowing.
• Recv-All-Multicasts—Device is in multicast promiscuous mode and therefore provides no multicast filtering.
• Running—Device is active and enabled.
