SNMP ICMP Group View
You can access the SNMP ICMP Group View by clicking on the ICMP button
in the Application View. The SNMP ICMP Group View displays the following
information for the hub:
Messages
Displays the total number of ICMP messages that the hub received or
attempted to transmit, including messages containing errors.
Errors
Displays the total number of ICMP messages that the hub received containing
errors or did not transmit because of errors.
Dest. Unreachable
Displays the total number of ICMP Destination Unreachable messages
received or transmitted by the hub. This indicates that a network or host was
unreachable, a protocol was not running, or IP datagram fragmentation was
necessary but disallowed because the Don’t Fragment flag was set.
Time Exceeds
Displays the total number of ICMP Time Exceeded messages received or
transmitted by the hub. This indicates that an IP datagram was discarded
because its TTL had expired or it was in the reassembly queue for too long.
Parameter Problems
Displays the total number of ICMP parameter problem messages received or
transmitted by the hub. This indicates an error in an IP datagram’s header.
Src Quench Msgs
Displays the total number of ICMP Source Quench messages received or
transmitted by the hub. This indicates that a network device is discarding IP
datagrams due to a lack of buffer space.
Redirects
Displays the total number of ICMP Redirect messages received by the hub if it
is operating as a host. ICMP redirects are transmitted to the host by a
gateway informing the host of another gateway on the same IP network that is
closer to the desired transmission destination.
This button allows you to access an additional SNMP ICMP Group View.
Table 3-1 provides the information displayed by the second SNMP ICMP
Group View.
