1. Verify that alternatename is being used for "Interface Alias Name" by getting a count
select count(*) from t_interface where itemname != alternatename;
(this will return a number, for example; 2248)
2. Set alternatename to equal itemname, as follows
update t_interface set alternatename = itemname;
3. Clear Item and Group cache, by running the following curl commands
curl -v -X PUT -H 'Content-Type: application/xml' -d '<emptybody/>' -u admin:<adminPW> http://<CAPCHOST>:8181/pc/center/webservice/invalcache/ITEM
curl -v -X PUT -H 'Content-Type: application/xml' -d '<emptybody/>' -u admin:<adminPW> http://<CAPCHOST>:8181/pc/center/webservice/invalcache/GROUP
