The gateway is automatically set to the interface address. To configure a DHCP Scope range, you would use the dhcpd address x.x.x.x-y.y.y.y ifName whereas x.x.x.x is the starting IP Address and y.y.y.y is the ending IP Address and the interface name is specified last.ĭNS Servers are configured in the same fashion using the dhcpd dns x.x.x.x y.y.y.y ifName command whereas x.x.x.x is the primary DNS and y.y.y.y is the secondary DNS. All of the DHCP services commands start with dhcpd followed by the specific configuration.
The DHCP Daemon is configured on a per interface basis and you specify an address range, not a subnet like you would on Cisco IOS. You can get into advanced configurations by providing DHCP options. The Cisco ASA DHCP Daemon operates as a simple DHCP Server providing dynamic IP Addresses, DNS and default gateway information and a domain name if configured. This type of configuration is commonly used at branch offices where no servers are located at. Configuration Example:ĪSA(config)# snmp-server host inside 10.1.1.Configuring DHCP Services on a Cisco ASA is not common however you may run into this scenario when working with the remote office Cisco ASA 5505 series firewalls. It is recommended to leave all traps enabled as the default setting. The default configuration has all snmp traps enabled ( snmp-server enable traps snmp authentication linkup linkdown coldstart). Step4: Enable the ASA to send snmp traps to the NMSĪSA(config)# snmp-server enable traps ] “community string” is like a preshared password which must be configured on both the ASA and the NMS in order for the two elements to communicate.ĪSA(config)# snmp-server community Where “interface name” is the ASA interface through which the NMS can be reached, and “ip address” is the NMS address. Step2: Identify the NMS host that can connect to the ASA for SNMP managementĪSA(config)# snmp-server host community
