lecstat Command

Purpose

Displays operational information about an Asynchronous Transfer Mode network protocol (ATM) Local Area Network (LAN) Emulation Client.

Syntax

lecstat [ -a -c -q -r -s -t -v ] Device_Name

Description

This command displays ATM LAN Emulation Client (LEC) operational information gathered by a specified LEC device. If a LEC device name is not entered, statistics for all available LEC's appear. Select a flag to narrow down your search results. You can display specific categories of information such as Configuration, LE_ARP Cache Entries, Virtual Connections, and Statistics, or you can choose to display all of the information categories.

You can also toggle debug tracing on or off and reset statistics counters.

The following information appears for all valid calls and contains the following fields:

Device Type

Displays a description of the LAN Emulation Client (example: Ethernet or Token Ring)

LAN MAC Address

Displays the LAN Emulation Client's 6-byte Ethernet or Token Ring MAC address.

ATM Address

Displays the LAN Emulation Client's 20-byte Asynchronous Transfer Mode (ATM) address.

Elapsed Time

Displays the real time period which has elapsed since statistics were last reset.

Driver Flags

The current LAN Emulation Client(LEC) device driver NDD status flags. Example status flags:

Broadcast       Allowing broadcast packets.
Dead            Requires re-open.
Debug           Internal debug tracing enabled.
Limbo           Attempting ELAN recovery.
Running         Fully operational on the ELAN.
Up              Device has been opened.

Configuration Information

Selected with the -a or -c flags. Displays the network administrator's pre-configured attributes, as well as the current ELAN configuration values as defined by the LANE Servers.

Lane LE_ARP Table Entries

Selected with the -a or -q flags. Displays the current LE Client ARP cache. Included are the type of entry, it's state, the remote LAN MAC address or route descriptor, the remote ATM address and some descriptive values.

Example Types

BUS-PP              Broadcast and Unknown Server (point-to-point).
BUS-MP              Broadcast and Unknown Server (multi-point).
Data                Data (point-to-point).
LES-PP              LE Server (point-to-point).
LES-MP              LE Server (multi-point).

Example States

Arping          Attempting to locate remote client/server via LE_ARP.
Connected       Fully connected to the remote client/server.
Flushing        Flushing the data path to the client/server.
Known           Remote address is known but no connection yet.
Unknown         Remote address in unknown and not able to LE_ARP yet.

Lane Servers and Statistics

Selected with the -a or -s flags. Displays the current Transmit, Receive, and General statistics for this LE Client, as well as the ATM addresses of the current and available LANE Servers.

Lane connections

Selected with the -a or -v flags. Displays the current list of virtual connections in use by this LE Client. Included are virtual path and channel values, remote ATM address, and some descriptive values such as whether this connection was started by the remote, whether it is a duplicate connection, or whether the remote station is proxied by another LE Client.

Exit Status

If you specify an invalid Device_Name, this command produces error messages stating that it could not connect to the device. Examples of an invalid device error message might be:

LECSTAT: No LANE device configured.
LECSTAT: Device is not a LANE device.
