Table 61 Security > Policies > Services Field Descriptions (Continued) Field Default Description IP Protocol Number (0-255) Configure Application Level No Gateway Application Level Gateway dhcp Specify the numeric identifier of the upper layer IP protocol that an IP packet should use. Specify whether to create an application level gateway, which filters incoming and outgoing information packets before copying and forwarding across the gateway. If you select Yes in this field, you are prompted with a new drop-down menu in which to select the Application Level Gateway type. If you select Yes for Configure Application Level Gateway, then specify the gateway type from this drop-down menu. The following application level gateway types are supported:  dhcp  dns  ftp  h323  noe  rtsp  sccp  sip  sips  svp  tftp  vocera Security > Server Groups Server Groups Page Overview The Server > Server Groups page displays all server groups currently configured, and the profiles and folders that are used by each server group, to include the following:  AAA  Captive Portal Auth  Management Auth  Stateful 802.1X Auth  TACACS Accounting  VPN Auth  Folder The list of servers in a server group is an ordered list. By default, the first server in the list is always used unless it is unavailable, in which case the next server in the list is used. You can configure the order of servers in the server group. In the Web UI, use the up or down arrows to order the servers (the top server is the first server in the list). In the CLI, use the position parameter to specify the relative order of servers in the list (the lowest value denotes the first server in the list). The first available server in the list is used for authentication. If the server responds with an authentication failure, there is no further processing for the user or client for which the authentication request failed. You can optionally enable fail-through authentication for the server group so that if the first server in the list returns an authentication deny, the controller attempts authentication with the next server in the ordered list. The controller attempts authentication with each server in the list until either there is a successful authentication or the list of servers in the group is exhausted. This feature is useful in environments where there are multiple, independent authentication servers; users may fail authentication on one server but can be authenticated on another server. 134 | Dell PowerConnect W Configuration Reference Dell PowerConnect W AirWave 7.2 | Configuration Guide
