Configuring the VLAN
Cisco ISA500 Series Integrated Security Appliance Administrator Guide 118

• Retry Count: Enter the number of retries. The security appliance repeatedly
tries to connect to the ISP after the link failure is detected. The default is 5.
• Retry Timeout: If the connection to the ISP is down, the security appliance
tries to connect to the ISP after a specified timeout. Enter the timeout in
seconds to re-connect to the ISP. The default is 5 seconds.
• Ping Detection: Choose this option to detect the WAN failure by pinging the
IP address that you specify in the following fields:
- Ping using WAN Default Gateway: Ping the IP address of the WAN
default gateway. If the default WAN gateway can be detected, the
network connection is active.
- Ping using these Hosts: Ping the specified remote hosts. Enter the IP
addresses in the Primary WAN Remote Host and Secondary WAN
Remote Host fields. In Failover mode, if the primary WAN remote host
can be detected, the network connection is active. In Load Balancing
mode, if the primary WAN and secondary WAN remote hosts can be
detected, the WAN connection is active.
• DNS Detection: Choose this option to detect the WAN failure by looking up
the DNS servers that you specify in the following fields:
- DNS Lookup using WAN DNS Servers: The security appliance sends
the DNS query for www.cisco.com to the default WAN DNS server. If the
DNS server can be detected, the network connection is active.
- DNS Lookup using these DNS Servers: The security appliance sends
the DNS query for www.cisco.com to the specified DNS servers. Enter
the IP addresses in the Primary WAN DNS Server and Secondary WAN
DNS Server fields. If the primary or secondary DNS server can be
detected, the network connection is active.

Configuring the VLAN
The Virtual LANs (VLANs) allow you to segregate the network into LANs that are
isolated from one another. Any PC that is connected to the specified LAN port is
on a separate VLAN and cannot access other VLANs. You can add up to 16
VLANs.
