Table 4.3, “APC Power Switch over SNMP” lists the fence device parameters used by
fence_apc_snmp
, the fence agent for APC that logs into the SNP device by means of the SNMP protocol.
luci Field | cluster.conf Attribute | Description |
---|---|---|
Name | name | A name for the APC device connected to the cluster into which the fence daemon logs by means of the SNMP protocol. |
IP Address or Hostname | ipaddr | The IP address or host name assigned to the device. |
UDP/TCP port | udpport | The UDP/TCP port to use for connection with the device; the default value is 161. |
Login | login | The login name used to access the device. |
Password | passwd | The password used to authenticate the connection to the device. |
Password Script (optional) | passwd_script | The script that supplies a password for access to the fence device. Using this supersedes the | parameter.
SNMP Version | snmp_version | The SNMP version to use (1, 2c, 3); the default value is 1. |
SNMP Community | community | The SNMP community string; the default value is private . |
SNMP Security Level | snmp_sec_level | The SNMP security level (noAuthNoPriv, authNoPriv, authPriv). |

SNMP Privacy Protocol Password | snmp_priv_passwd | The SNMP privacy protocol password. |
SNMP Privacy Protocol Script | snmp_priv_passwd_script | The script that supplies a password for SNMP privacy protocol. Using this supersedes the | parameter.
Power Wait (seconds) | power_wait | Number of seconds to wait after issuing a power off or power on command. |
Power Timeout (seconds) | power_timeout | Number of seconds to continue testing for a status change after issuing a power off or power on command. The default value is 20. |
