Feature Description
The SMF supports the addition of a dynamic pool, IPv4, or IPv6 address-range to a dynamic pool by default. The new chunks are added to the respective tags, such as DNN, and are assigned from the same pool.
To delete a dynamic pool or an IPv4 or IPv6 address-range from a dynamic pool:
-
Configure the pool or address-range as offline. The IPAM then stops assigning addresses from the respective pool or address-range.
-
Use the following clear-subscriber CLI commands to delete the subscribers based on respective pool or address range that are configured to offline mode:
-
clear subscriber ipv4-pool pool_name
-
clear subscriber ipv4-range pool_name/start_of_range
-
clear subscriber ipv6-pool pool_name
-
clear subscriber ipv6-range pool_name/start_of_range
-
-
Use the following cdl show CLI commands and wait until all the subscribers are deleted:
-
cdl show sessions count summary filter { key ipv4-pool: pool_name condition match }
-
cdl show sessions count summary filter { key ipv4-range: pool_name/start_of_range condition match }
-
cdl show sessions count summary filter { key ipv6-pool: pool_name condition match }
-
cdl show sessions count summary filter { key ipv6-range: pool_name/start_of_range condition match }
-
-
After all the subscribers are deleted, delete the pool or address-range from the IPAM configuration.
