Parameters
all: Specifies all the IP addresses (or IP address pools).
address-list: IP address list. You need to provide this argument in the format of
start-ip-address [ ip-address-number ] & < 1-10 >, where start-ip-address is the start IP
address of an IP address range in the address pool, ip-address-number specifies the
number of the successive IP addresses following start-ip-address in the range, and & <
1-10 > means you can specify up to ten IP addresses/IP address ranges.
Description
Use the am ip-pool command to configure the access management IP address pool on a
port. For a port with the access management IP address pool configured, only the hosts
with their IP addresses being in the access management pool can access external
networks through the port.
Use the undo am ip-pool command to remove part of or all the IP addresses from the
access management IP address pool of a port.
By default, the access management IP address pool is null.
Note that:
Before configuring the access management IP address pool of a port, you need to
configure the interface IP address of the VLAN to which the port belongs, and the IP
addresses in the access management IP address pool of a port must be in the same
network segment as the interface IP address of the VLAN which the port belongs to.
If an access management address pool configured contains IP addresses that belong
to the static ARP entries of other ports, the system prompts you to delete the
corresponding static ARP entries to ensure the access management IP address pool
can take effect.
Examples
# Configure the access management IP address pool on Ethernet 1/0/1 to allow hosts with
their IP addresses being in the range 202.112.66.2 to 202.112.66.20 and 202.112.65.1 to
access external networks through the port.
