Commands for Persistence Modes, and NAT Modes
configure proxy-ip
configure proxy-ip <IP address> {- <IP address>}
Description
Sets a proxy IP address or a range of proxy addresses.
Syntax Description
Default
N/A.
Usage Guidelines
You must have administrator privileges to issue this command.
To function properly in full-NAT mode, the application switch requires that proxy IP addresses be
conÞgured. These proxy addresses are used as the source IP addresses for the outbound connection to
the server. One proxy address must be conÞgured for each 63,000 sessions active at one time. For full
system capacity, you must conÞgure 32 IP addresses.
Proxy-IP addresses do not need to be contiguous. You can use multiple commands to specify different
ranges of IP addresses to use as proxy addresses. The only restriction is that all addresses must be on
the same subnet as the main system IP address.
NOTE
Do not change the proxy IP while the application switch is running.
If VRRP is also enabled, you typically must specify a different proxy IP address for each of the VRRP
peers. The one exception to this requirement is that if you are using automatic synchronization and you
have conÞgured all VRRP classes to track failure of all other VRRP classes, then you may use the same
proxy IP address on the two switches. For additional information about VRRP, see Chapter 5.
You must use the build command to commit the conÞguration changes made by this command. You
must boot the application switch for the new proxy IP information to take effect.
Example
The following command conÞgures 32 consecutive proxy IP addresses.
config proxy-ip 10.1.1.11 - 10.1.1.42
History
This command was available in ExtremeWarePx 1.1.
IP address A proxy IP address. Two IP addresses separated by a hyphen indicate a range of
addresses; the command configures all addresses in the specified range as proxy IPs.
