By default, IPv4 address pools do not have constant indexes. The indexes for these pools automatically change after the device where these pools reside restarts. After a device where IPv4 address pools reside restarts, the NMS loses all IPv4 address pool statistics and can no longer monitor these pools. This problem can be solved by configuring the constant index function for IPv4 address pools.
After the ip-pool constant-index enable command is used, the indexes of the IPv4 address pools do not change after the device restarts. The constant-index index command is automatically generated in the views of all IPv4 address pools configured on the device for users to check the constant indexes. But the constant-index command cannot be used to change the automatically generated constant indexes for IPv4 address pools.
The system view is displayed.
The constant index function is enabled for IPv4 address pools.
The configuration is committed.
