network-extension netpool

Function

The network-extension netpool command sets the client IP address allocation method to address pool for network extension.

The undo network-extension netpool command deletes the address pool.

The network-extension netpool new-netpool command changes the address pool.

Format

network-extension netpool start-ip end-ip mask [ virtual-ip { clear-all | clear-invalid | reserve-all } ]

undo network-extension netpool { start-ip | pool-name } [ virtual-ip { clear-all | clear-invalid | reserve-all } ]

network-extension netpool start-ip new-netpool start-ip end-ip mask [ virtual-ip { clear-all | clear-invalid | reserve-all } ]

Parameters

Parameter	Description	Value
start-ip	Specifies the start IP address of the address pool.	The value is in dotted decimal notation.
end-ip	Specifies the end IP address of the address pool.	The value is in dotted decimal notation.
mask	Specifies the subnet mask.	The value is in dotted decimal notation.
virtual-ip clear-all	Clears the virtual IP addresses of all users.	-
virtual-ip clear-invalid	Clears virtual IP addresses not in the new address range.	-
virtual-ip reserve-all	Keeps the virtual IP addresses of all users.	-
pool-name	Specifies the name of the address pool.	The value is a string of 1 to 31 case-sensitive characters.
new-netpool	Indicates the IP address pool after modification.	-

Usage Guidelines

When the client address allocation method is address pool, virtual-ip clear-invalid is used by default.

clear-all, clear-invalid, and reserve-all take effect only on users bound with virtual IP addresses.
When you configure a virtual IP address pool, do not add the IP address of any virtual gateway or SSL VPN interface to the address pool. Otherwise, clients cannot obtain virtual IP addresses to run network extension services.
If you select the IP address pool mode, specify at least one IP address pool. The SSL VPN address pool cannot contain an allocated intranet IP address.
If the Windows XP OS or earlier versions are used, do not use virtual IP addresses containing 192.168.x.255 to ensure that network extension is normally enabled.
When configuring the network extension address pool on multi-virtual gateway networks, ensure that addresses in the address pool on the SSL VPN do not conflict with those on the DHCP server.

When a network extension address pool is added, online users will not go offline. When a network extension address pool is modified, if the IP address of an online user is still in the address pool after modification, the user will not go offline. Otherwise, the user is forced offline. When a network extension address pool is deleted, the online users who are using the IP addresses in the address pool are forced offline, and other users are still online.

Example

# Add network segment 10.1.1.1-10.1.1.5 to the address pool.

<sysname> system-view
[sysname] v-gateway abc
[sysname-abc] service
[sysname-abc-service] network-extension netpool 10.1.1.1 10.1.1.5 255.255.255.0
