Configuring SNMP Support
Enabling the SNMP service on the ASA
ciscoasa# configure terminal ciscoasa(config)# snmp-server enable ciscoasa(config)# snmp-server host logical_if_name IP_address poll community text version 2c ciscoasa(config)# writelogical_if_name is one of the ASA’s logical interface names which communicate with the NMS server.
IP_address is an IP address of the NMS server where the VPNTTG program is running.
text is an ASA’s read SNMP community string.
Checking a list of the supported SNMP MIBs on the ASA
ciscoasa# show snmp-server oidlist
Checking a SNMP availability from the NMS server where the VPNTTG program is running
Install snmpwalk through yum:[root@localhost ~]# yum -y install net-snmp-utilsInstall snmpwalk through apt-get:
[root@localhost ~]# apt-get install snmpThe syntax is as follows:
snmpwalk -v2c -c <community> <ip_address> 1.3.6.1.4.1.9.9.171Where:
community - is a SNMP read community of the VPN server
ip_address - is an IP address of the VPN server
In this example, SNMP community is - "public" and IP address is - 10.0.0.18
