Note that Frame 38 reaches the end of the table, indicated by the GetResponse given in Frame 40, which moves to a different group within the OID tree. This final value is the lexicographical next item in the router’s MIB, object snmpInPkts, the first object of the SNMP group. This means that the router did not have any item in the Transmission group {mib-2 10} in its MIB View. (These groups were in the router’s MIB, however, so access to those groups using the same community name was not possible.)

The UDP table constructed from the data in Trace 4.4.2 is as follows:

udpTable

udpLocalAddress udpLocalPort

0.0.0.0   69 (TFTP)
0.0.0.0 161 (SNMP)
0.0.0.0 520 (Router)
