suse 10如何通过snmp查询网卡状态

首先保证机器上要安装net-snmp

# rpm -qa|grep snmp
net-snmp-5.3.0.1-25.25

# rpm -qa|grep snmp
net-snmp-5.3.0.1-25.25

被查询的机器上需要开启snmpd服务：
1. 编辑/etc/snmp/snmpd.conf，suse 10上该文件默认是不能工作的，将文件替换成下面的内容即可。

# First, map the community name (COMMUNITY) into a security name
# (local and mynetwork, depending on where the request is coming
# from):

#       sec.name  source          community
com2sec notConfigUser  default  public

####
# Second, map the security names into group names:

#               sec.model  sec.name
group   notConfigGroup v1           notConfigUser

group   notConfigGroup   v2c           notConfigUser

####
# Third, create a view for us to let the groups have rights to:

#           incl/excl subtree                          mask
view all    included  .1                               80

####
# Finally, grant the 2 groups access to the 1 view with different
# write permissions:

#                context sec.model sec.level match  read   write  notif
access notConfigGroup ""      any       noauth    exact  all    none   none

# First, map the community name (COMMUNITY) into a security name
# (local and mynetwork, depending on where the request is coming
# from):

#       sec.name  source          community
com2sec notConfigUser  default  public

####
# Second, map the security names into group names:

#               sec.model  sec.name
group   notConfigGroup v1           notConfigUser

group   notConfigGroup   v2c           notConfigUser

####
# Third, create a view for us to let the groups have rights to:

#           incl/excl subtree                          mask
view all    included  .1                               80

####
# Finally, grant the 2 groups access to the 1 view with different
# write permissions:

#                context sec.model sec.level match  read   write  notif
access notConfigGroup ""      any       noauth    exact  all    none   none

2. 启动snmpd

#service snmpd restart

#service snmpd restart

3. 配置snmpd自动运行

# chkconfig -e snmpd
snmpd  3

# chkconfig -e snmpd
snmpd  3

4. 通过snmp查询所有网卡名字

# snmpwalk -v 2c -c public localhost IF-MIB::ifDescr
IF-MIB::ifDescr.1 = STRING: lo
IF-MIB::ifDescr.2 = STRING: eth0

# snmpwalk -v 2c -c public localhost IF-MIB::ifDescr
IF-MIB::ifDescr.1 = STRING: lo
IF-MIB::ifDescr.2 = STRING: eth0

5. 查询指定网卡状态

# snmpwalk -v 2c -c public localhost IF-MIB::ifOperStatus.2
IF-MIB::ifOperStatus.2 = INTEGER: up(1)

# snmpwalk -v 2c -c public localhost IF-MIB::ifOperStatus.2
IF-MIB::ifOperStatus.2 = INTEGER: up(1)

6. 查询网卡流量

# snmpwalk -v 2c -c public localhost IF-MIB::ifHCOutOctets.2    //网卡出流量
IF-MIB::ifHCOutOctets.2 = Counter64: 3118479769
# snmpwalk -v 2c -c public localhost IF-MIB::ifHCInOctets.2    //入流量
IF-MIB::ifHCInOctets.2 = Counter64: 2352396350
