Chapter 9 Device Network Settings Table 97 Device Operation > Device Configuration > Network > Interface > Ethernet > Edit (continued) LABEL DESCRIPTION Authentication Select an authentication method, or disable authentication. To exchange OSPF routing information with peer border routers, you must use the same authentication method that they use. Choices are: Same-as-Area - use the default authentication method in the area None - disable authentication Text - authenticate OSPF routing information using a plain-text password MD5 - authenticate OSPF routing information using MD5 encryption Ping Check The interface can regularly check the connection to the gateway you specified to make sure it is still available. You specify how often the interface checks the connection, how long to wait for a response before the attempt is a failure, and how many consecutive failures are required before the ZyWALL stops routing to the gateway. The ZyWALL resumes routing to the gateway the first time the gateway passes the connectivity check. Enable Select this to turn on the connection check. Check Method Select the method that the gateway allows. Select icmp to have the ZyWALL regularly ping the gateway you specify to make sure it is still available. Check Period Check Timeout Check Fail Tolerance Ping Default Gateway Ping this address DHCP Setting DHCP Select tcp to have the ZyWALL regularly perform a TCP handshake with the gateway you specify to make sure it is still available. Enter the number of seconds between connection check attempts. Enter the number of seconds to wait for a response before the attempt is a failure. Enter the number of consecutive failures before the ZyWALL stops routing through the gateway. Select this to use the default gateway for the connectivity check. Select this to specify a domain name or IP address for the connectivity check. Enter that domain name or IP address in the field next to it. Select what type of DHCP service the ZyWALL provides to the network. Choices are: None - the ZyWALL does not provide any DHCP services. There is already a DHCP server on the network. DHCP Relay - the ZyWALL routes DHCP requests to one or more DHCP servers you specify. The DHCP server(s) may be on another network. DHCP Server - the ZyWALL assigns IP addresses and provides subnet mask, gateway, and DNS server information to the network. The ZyWALL is the DHCP server for the network. These fields appear if the ZyWALL is a DHCP Relay. Vantage CNM User's Guide 253
