Any inputs on the correct format of IPv6 address that needs to be passed to
the following function?
Or is there a bug here?
*netsnmp_ds_set_string(NETSNMP_DS_LIBRARY_ID,NETSNMP_DS_LIB_CLIENT_ADDR_V6,effective_ipv6);*
We tried to pass the following format of IP address to the above function,
but nothing seems to work.
[IPv6_Address]:161
[IPv6_Address]
IPv6_Address
