NAME

be reached through the local endpoint and the routes to reach them.

DESCRIPTION
You can use the server-discovery component to configure the dynamic
discovery of servers and the routes to reach them through the local
endpoint. The local endpoint advertises these routes to any remote
endpoints to which it is connected.
EXAMPLES
list server-discovery all-properties
Displays the settings for dynamic discovery of advertised routes.
modify server-discovery mode disabled
Disables the dynamic discovery of advertised routes.
OPTIONS
auto-save
Specifies whether the system automatically saves the subnets that
it discovers that can reached through the local endpoint. The
default value is enabled.
description
User defined description.
filter-mode
Specifies whether the subnets you add using the attribute subnet-
filter are excluded from or included in the discovery of
advertised routes. If you specify include, and do not specify any
IP addresses, no subnets are discovered. The default is exclude
with no IP addresses specified, which means that all advertised
routes that conform to the specified attributes are discovered.
idle-time-limit
Specifies the maximum length of time a route can be idle without
being removed from discovery. The default value is 0. Use the
attribute time-unit to set the unit of measure. Use the attribute
min-idle-time to set the minimum length of idle time.
ip-ttl-limit
Specifies the number of network segments on which a packet is
allowed to travel before the route is removed from discovery. The
more routers a packet travels through, the smaller the ip ttl
value is. The range is 0 to 255. The default value is 5.
max-server-count
Specifies the highest number of servers the system discovers
before it stops looking. The default value is 50.
min-idle-time
Specifies the minimum length of time a route must be idle before
being removed from discovery. The default value is 0, which
indicates that idle time is not considered in discovery. Use the
attribute time-unit to set the unit of measure. Use the attribute
idle-time-limit to set the maximum length of idle time.
min-prefix-length-ipv4
Specifies the minimum prefix length for route aggregation in IPV4
networks. The range is 0 to 32. The default value is 32.
min-prefix-length-ipv6
Specifies the minimum prefix length for route aggregation in IPV6
networks. The range is 0 to 128. The default value is 128.
mode Enables or disables the dynamic discovery of servers that can be
reached through the local endpoint. For server discovery to take
place, the setting mode of the component wom endpoint-discovery
must not be set to disabled.
rtt-threshold
Specifies that the system does not add servers it discovers with a
round-trip time greater than this value, in milliseconds. The
default value is 10.
subnet-filter
Specifies the IP addresses of the subnets to include in or exclude
from the discovery of advertised routes, depending on the setting
you selected for the attribute filter-mode. The default is none.
If you selected include for the attribute filter-mode, and do not
specify any IP addresses, no subnets are discovered.
time-unit
Specifies the unit of measure (days, hours, or minutes) for the
length of idle time specified using the attributes idle-time-limit
and min-idle-time.
