未在 MIB 中定义的 OID 中的尾随数字和点

Question

我正在尝试更深入地了解SNMP，以便正确使用其功能。我有一个监视无线接入点 (WAP( 状态的任务。AP 由知道 AP 状态的控制器控制，这是我使用 SNMP 提取信息的地方。我发现这个 OID 如果 AP 断开连接，则显示"0">

# snmpget -v2c -c xxx 1.2.3.4 SNMPv2-SMI::enterprises.25053.1.2.2.1.1.2.1.1.3.6.240.62.144.17.39.0
SNMPv2-SMI::enterprises.25053.1.2.2.1.1.2.1.1.3.6.240.62.144.17.39.0 = INTEGER: 0

我使用net-snmp。我安装了此产品的所有MIB。然而，当我做snmptranslate时，它只解释了OID中的某个点

# snmptranslate -m ALL -Td SNMPv2-SMI::enterprises.25053.1.2.2.1.1.2.1.1.3.6.240.62.144.17.39.0
RUCKUS-ZD-WLAN-MIB::ruckusZDWLANAPStatus.'..>..''.0
ruckusZDWLANAPStatus OBJECT-TYPE
-- FROM       RUCKUS-ZD-WLAN-MIB
SYNTAX        INTEGER {disconnected(0), connected(1), approvalPending(2), upgradingFirmware(3), provisioning(4)}
MAX-ACCESS    read-only

DESCRIPTION   "The connection status with ZD."

不解释尾随的 6.240.62.144.17.39.0。我还发现，这个尾随部分在其他 OID 中用于获取有关 AP 的其他信息，例如名称、IP 地址、序列号......等

所以我的问题是，我在哪里可以找到这个尾随字符串中的每个数字的含义？它在MIB中定义吗？它与SNMP"表"有关吗？谢谢！

由于该表使用MacAddress作为索引，因此 OID 看起来像这样。
