Net Link Manager
Net Link Manager is an Enterprise Edge service that provides constant WAN link
status monitoring. Net Link Manager is also where you select your WAN primary
and backup interfaces.
When Net Link Manager detects a primary WAN link failure, Net Link Manager
automatically establishes a backup WAN connection. Net Link Manager monitors
theWAN primary link by performing multiple tests.When a predetermined number
of tests fails, Net Link Manager establishes the backup connection.
The backup connection uses a V.90 modem (North America) or an ISDN line.
When the backup WAN connection is active, Net Link Manager continues to
monitor the status of the primary WAN link connection. When the primary WAN
linkconnectionbecomesavailableagain,NetLinkManagerdisconnectsthebackup
connection and re-establishes the primary WAN link.
Note: Net Link Manager can provide backup for one link only, even though there
are two primary links (one provided from each WAN interface). Net Link
Manager backs up the link who is responsible for the next hop address.
Server Address Allows you to tell the web server what IP address to use for interacting with
HTTP clients. Since Enterprise Edge server typically has more than one IP
interface and associated IP Address, users can choose this value. This value
is automatically set to the IP Address of the first LAN interface and changes
when the latter changes. Exercise caution if modifying this value.
Cache Mode Allows you to enable or disable the cache-mode of operation.
Cache Size Allows you to specify the maximum size (1 -1 100,000), in KB, of the cache.
GarbageCollection
Interval
Allows you to specify the interval, in hours, between garbage collection
operations on the cache.
The values are 1 to 24.
Cache Maximum
Life
Allows you to specify the maximum life, in hours, on the proxy server for
the HTTP pages cached in it.
Values are 1 to 24.
Maximum Server
Threads
Allows you to specify the number of threads ready to serve HTTP requests
in the proxy server.
Values are 1 to 255.
Warning
If an ISDN dial-up connection is used as the primary WAN connection (that is,
no permanent WAN connection is configured), no backup link is available.
