A.3.3 Switch Information

On the host, at a command line, type the following commands and note the responses:

•atmstat fa0 command

•netstat -ai command

•asxmon command

•cport command

Log in to the ATM Management Interface (AMI) and open a session on the switch fabric to check the following:

•conﬁguration spans show

•conﬁguration port show

•conﬁguration uni30 show

•Conﬁguration of Network Modules (TAXI, DS3, DS1, SONET, E3, E1, and/or J2)

Typical responses are shown under each command. The responses from these commands enables support to gather sufﬁcient information to resolve the majority of problems.

For example, an OC-3c network module that is removed from slot A of the old switch fabric must be installed in slot A of the new switch fabric. Therefore, it is recommended that you label all network connections and network modules before removing them 5-17 Hardware Maintenance ProceduresCAUTION Make sure the replacement board is properly aligned in the slot in the next step Hardware Maintenance Procedures 5-18 Software Upgrade Instructions CHAPTERtar -xvf device 6.1 Obtaining the Software Upgrade File via DisketteSoftware Upgrade Instructions eject deviceforeextract device Software Upgrade Instructionsmv ﬁlename /tftpboot 6.2 Performing the Software Upgrademkdir /tftpboot operation upgrade ?operation upgrade 169.144.3.54asx-scp4.0.01.3 operation upgrade 169.144.3.54ASX-200BX4.0.01.3Software Upgrade Instructions Software Upgrade Instructions Reboot the switchy? y6.3 Changing between Multiple Versions of Software Software Upgrade InstructionsSoftware Upgrade Instructions localhostoperation rebootAre you sure you want to reboot this switch n? y 6.4.1 Overview 6.4 Using bootp to Download Software to the Switch6.4.2 Setting Up Your bootp Server Software Upgrade Instructions6.4.3 Adding an Entry for Your Switch in the bootptab File 6-10Software Upgrade Instructions 6-11 Software Upgrade InstructionsThe variables in the previous example are deﬁned as follows 6.4.4 Setting Up a tftpboot Server 6-12Software Upgrade Instructions Troubleshooting A.1 Adapter Hardware TroubleshootingAPPENDIX A Troubleshooting Figure A.1 -
