I've got a product that provides number of services.  When one of the services
fail, it sends a SNMP trap indicating a service failure but instead of
using a name we get an interger value.

Example:
1 = DNS
2 = DHCP
3 = LDAP
etc

Is there a way of substituting the interger value with name?  So when
operators see the event, it's obvious what failed.
