![]() Identify the IP address of the SNMP management station with the snmp-server host command.Receiving Requests and Sending Syslog Trapsįollow these steps to receive requests and send traps from the firewall to an SNMP management station: firewall supports two types of traps, generic and syslog traps. Two mechanisms work with SNMP, firewall responds to an SNMP request from a management station and the firewall sends a trap, which is an event notification. Table 7-1: System OID in firewall Platforms Table 7-1 lists the system OID in firewall platforms: firewall provides system OID in SNMP event traps & SNMP variable based on the hardware platform: Traps are different than browsing they are unsolicited "comments" from the managed device to the management station for certain events, such as link up, link down, and syslog event generated.Īn SNMP object ID (OID) for firewall displays in SNMP event traps sent from the firewall. Syslog messages generated by the SNMP module now specify the interface name instead of an interface number.The SNMP "ifOutUcastPkts" object now correctly returns the outbound packet count.The MIB-II ifEntry.ifAdminStatus object returns 1 if the interface is accessible and 2 if you administratively shut down the interface using the shutdown option of the interface command.cfwGenericNotification NOTIFICATION-TYPE.cfwAccessNotification NOTIFICATION-TYPE.cfwContentInspectNotification NOTIFICATION-TYPE.cfwSecurityNotification NOTIFICATION-TYPE.The firewall does not support the following in the Cisco Firewall MIB: The Cisco Firewall MIB and Cisco Memory Pool MIB are available. Browsing means doing an snmpget or snmpwalk of the MIB tree from the management station to determine values. ![]() Browsing an MIB is different from sending traps. You can browse the System and Interface groups of MIB-II. Use CiscoWorks for Windows or any other SNMP V1, MIB-II compliant browser to receive SNMP traps and browse an MIB. Security-related events sent via the Cisco Syslog MIB:.Authentication failure (mismatched community string).Link up and link down (cable connected to the interface or not cable connected to an interface working or not working).The firewall SNMP traps available to an SNMP management station are as follows: SNMP events can be read, but information on the firewall cannot be changed with SNMP. Using SNMP, you can monitor system events on the firewall. The Cisco Firewall MIB and Cisco Memory Pool MIB are also available. The firewall SNMP MIB-II groups available are System and Interfaces. Use snmp-server host command to specify which systems receive the SNMP traps. The snmp-server command causes the firewall to send SNMP traps so that the firewall can be monitored remotely.
