open_failover_ports
This variable enables or disables network failover when a VLAN has port
lockdown enabled.
The following command enables network failover:
b global open_failover_ports enable
The following command disables network failover:
b global open_failover_ports disable
persist map_proxies
The default setting for the map proxies for the persistence variable is
enable. The AOL proxy addresses are hard-coded. This enables you to use
client IP address persistence with a simple persist mask, but forces all AOL
clients to persist to the same server. All AOL clients will persist to the node
that was picked for the first AOL client connection received.
The class B networks, 195.93 and 205.188, are mapped to 152.163 for
persistence. For example, client 195.93.3.4 would map to 152.63.3.4 for
persistence records only. This mapping is done prior to applying the persist
mask. Use bigpipe pool persist dump to verify that the mapping is
working.
We recommend that in addition to setting this sysctl variable, you set a
persist mask of 255.255.0.0 so that all the AOL addresses map to a common
address. For example, Table 7.2 is an example of how setting this variable
and a persist mask of 255.255.0.0 would map a sample set of client
addresses.
persist timer
The following command forces the persistent connection timer to reset on
each packet for persistent sessions. This is the default value.
b global persist timer limit
