For information about the IP pools and Digital Subscriber Line (DSL) switches, refer to CISCO-DSL-PROVISION-MIB.
To monitor free addresses and addresses in use, refer to the cdslLocalIpAddrPoolTable table.
Refer to this example:
nms_server# snmpwalk -v 2c -c <community string> <device name or ip address> 126.96.36.199.188.8.131.52.184.108.40.206
220.127.116.11.18.104.22.168.22.214.171.124.126.96.36.199.188.8.131.52.111.111.108 : Unsigned32: 252
184.108.40.206.220.127.116.11.18.104.22.168.22.214.171.124.126.96.36.199.111.111.108 : Unsigned32: 1
In the example, the number of free IP addresses in the pool is 252, and the number of used IP addresses is 1.
