Bridging Commands
Page 17-15
Field descriptions
The following section describes the fields displayed in the above table.
Frames discarded to full Forwarding Database. The number of frames that were not transmitted
because the forwarding database is full. The forwarding database holds all known MAC
address for this bridge and is used to learn the next hop MAC address for the packet(s) in
question.
Slot/Intf/Service/Inst. The slot number (Sl), interface (port) number (Intf), type of service
(Service), and service instance (Inst). For example, a bridge service on port 1 of slot 3 would
be:
3/1/Brg/1
Services provide connection options for switches in a LAN, between LANs, or in a WAN.
Other possible services include trunking, routing, and LANE. It is possible to have more than
one instance of a service if there are more than one connections on a single port.
Frames In. The number of frames received on the associated port.
Frames Out. The number of frames sent on the associated port.
In Frames Discards. The number of received frames discarded due to error.
MTU Exceeded Discards. The number of frames that were discarded because they exceeded the
Maximum Transmission Unit (MTU) size. The MTU is set to the default of the media type
(Ethernet, Token Ring, etc.) and is not configurable.
Delay Exceeded Discards. Frames that were delayed, usually due to collisions, but that were
ultimately transmitted.
Flood Limit Discards. The number of frames that were discarded because they exceeded the
flood limit set for the port or the group in which this port is a member. This flood limit is set
with the flc command for groups or the modvp command for ports. For more information on
setting flood limits, see Setting Flood Limits on page 17-21 for the flc command. For details on
using the modvp command, see Chapter 19, “Managing Groups and Ports.”
