Device Flags

The Device Flags field shows information about the physical device. It can be one or more of the following:

• Down—Device has been administratively disabled.
• Hear-Own-Xmit—Device will hear its own transmissions.
• Link-Layer-Down—The link layer protocol has failed to successfully connect with the remote end point.
• Loopback—Device is in physical loopback.
• Loop-Detected—The link layer has received frames that it sent and suspects a physical loopback.
• No-Carrier—Where the media supports carrier recognition, this indicates that no carrier is currently seen.
• No-Multicast—Device does not support multicast traffic.
• Present—Device is physically present and recognized.
• Promiscuous—Device is in promiscuous mode and will see frames addressed to all physical addresses on the media.
• Quench—Device is quenched because it overran its output buffer.
• Recv-All-Multicasts—No multicast filtering (multicast promiscuous).
• Running—Device is active and enabled.
