Displaying Information About the Access Server

Introduction

The LIST/MONITOR/SHOW SERVER command displays information about the access server or about data maintained by the access server. You can obtain characteristics, counter, status, and summary displays for the access server.

Specifying the Prompt

The factory-set default access server prompt is Local>. You can change this prompt to any ASCII character, with a restriction of 1 to 16 characters. The following shows how to change this prompt to Engineering>. You should include a space at the end of the prompt, to leave space between the prompt and user commands.

Local> CHANGE SERVER PROMPT "Engineering> "

To go back to the default Local> prompt, enter the following command:

Local> CHANGE SERVER PROMPT ""

This command specifies the access server prompt displayed to all port users when in local mode, with the exception of the RCF management port.

Displaying Access Server Counters

The LIST/MONITOR/SHOW SERVER COUNTERS command displays the values for the global counters maintained by the access server. The counters display is useful for detecting network problems.

The first line displays the access server software version number and base level, LAT software version number, ROM version number, and the time that the access server has been running since the last downline load, expressed as days hours:minutes:seconds.

The COUNTERS data appear in two blocks:

∙Ethernet data link counters — The upper block is for datagrams sent between the access server and all nodes on the Ethernet network. Some of the fields displayed are bit masks, the values of which tell the reasons for certain events.

∙LAT protocol counters — The lower block is for messages transmitted between the access server and all LAT service nodes. The access server maintains some of these counters for each service node with which it communicates. Refer to the node counters display descriptions in Viewing LAT Node Counters Information in this chapter.
