We have a router that had to have a change to its name.  The IP address stayed 
the same, it was corrected in the DNS.  The old name is not in the host file; 
has no object ID when I do ovobjprint -s {router name};  snmpwalk  -c  gets no 
info with the old name.   However, if I select the router from the map and do 
Tools, Mib browser, Snmp, under the Name of IP Address the old router name 
shows.  Where can I change this to get the correct name to show?
