Introduction The "Compaq NIC Agents - Linux" software release contains the SNMP Network Interface Card Agents and related files that enable Linux to support the NIC reporting features of the Compaq Insight Manager (CIM) and Insight Manager XE. 2. Documentation Updates and Corrections This section contains information on known errors and omissions in the "Compaq NIC Agents - Linux" section of the Compaq Managements Agents for Linux Servers HOWTO. 3. Known Issues 1) The e100 driver does not report the first link status change if the driver is loaded and the network cable is not plugged in. However, subsequent link status changes are detected and reported. 2) The e100 driver Driver_Name is a description of the driver instead of the name of the driver (e100). 3) NIC events are not reported to the Integrated Management Log (IML) in this release. 4) Information CIM reports from MIB-II may not be correct, such as the speed of the link. 4. Installation 4.1 Before installation 1) The NIC Agents require: Compaq Foundation Agent, version 5.00, (cmafdtn-5.00-x) RedHat Linux version 7.0 UCD-SNMP version 4.1.2 Compaq tested and supported NIC drivers from http://www.compaq.com/products/servers/linux/linux-drivers.html. 2) The NIC Agents are configured to start at the same runlevels as the snmpd daemon. Please insure the snmpd daemon is configured to start at the desired runlevels before installing the NIC Agents, otherwise the NIC Agents will need to be manually configured after installation using chkconfig or a similar tool. 4.2 Installing the NIC Agents NOTE: If version 4.90-x of the Compaq NIC Agents is currently installed on your server, the agents must be removed before installing a newer version. Check the version by issuing the following command: # rpm -q cmanic If you see a line containing "cmanic-4.90", remove the agents with the following command before installing the new agents # rpm -e cmanic Use following command to install or upgrade Compaq NIC Agents: # rpm -Uvh cmanic-x.xx-x.i386.rpm Where "x" is the version number of the Compaq NIC Agent package. 4.3 After installation a. The Compaq NIC Agents are configured to start at the same runlevels as the snmpd daemon. To start the NIC agent immediately after installation, enter the following command: # /etc/rc.d/init.d/cmanic start b. To determine the NIC drivers that support /proc file system reporting, run the following commands: find /proc/net/PRO_LAN_Adapters -name "eth*.info" \ -exec grep Driver_Name {} \; 2>/dev/null | uniq find /proc/net/nicinfo -name "eth*.info" \ -exec grep Driver_Name {} \; 2>/dev/null | uniq NIC drivers supporting this reporting mechanism will be displayed as: Driver_Name name_of_driver where name_of_driver is the actual name of the loaded driver. The latest NIC drivers tested by Compaq can be downloaded from http://www.compaq.com/products/servers/linux/linux-drivers.html c. The following command line arguments can be passed to cmanicd from the /opt/compaq/nic/etc/cmanicd script: -p poll_time specifies the number of seconds between data caching/poll intervals. NIC drivers are only queried when a request comes in and the cached information is older than the specified poll interval. The default value is 20 seconds. The minimum poll time is 10 seconds. -s set_state specifies whether SNMP set commands are allowed for this agent. A set_state of OK (default) means that SNMP set commands are allowed. A set_state of NOT_OK means that SNMP set commands are not allowed. -t trap_state specifies whether the NIC agent is allowed to send traps. A trap_state of OK (default) indicates the NIC agent may send SNMP traps. A trap_state of NOT_OK means that NIC agent is not allowed to send traps. For example, to set the poll interval to 30 seconds and prevent traps one would change PFLAGS= to PFLAGS="-p30 -t NOT_OK" in the /opt/compaq/nic/etc/cmanicd script. The resource control script to start the cmanicd daemon is cmanic. 5. New Features This is the initial release. 6. Supported Products The Compaq NIC Agents for Linux is supported on Compaq servers tested for running RedHat 7.0. Please refer to the "Linux Server certification matrix" at http://www.compaq.com/products/servers/linux/ for a complete list of Compaq servers that have been tested with RedHat 7.0. Use of this software on equipment not specifically tested by Compaq may produce unreliable or undesirable results. Compaq does not warrant the fitness or compatibility of this software on untested hardware. ------------------------------------------------------------------------ Copyright 2001 Compaq Computer Corporation.
