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.”
