Chapter 13 Monitoring

Monitoring Statistics MIB-II ICMP

Errors Received/Transmitted

The number of ICMP messages that the VPN 3002 received but determined to have ICMP-specific errors (bad ICMP checksums, bad length, etc.).

The number of ICMP messages that the VPN 3002 did not send due to problems within ICMP such as a lack of buffers.

Destination Unreachable Received/Transmitted

The number of ICMP Destination Unreachable messages received/sent. Destination Unreachable messages apply to many network situations, including inability to determine a route, an unusable source route specified, and the Don’t Fragment flag set for a packet that must be fragmented.

Time Exceeded Received/Transmitted

The number of ICMP Time Exceeded messages received/sent. Time Exceeded messages indicate that the lifetime of the packet has expired, or that a router cannot reassemble a packet within a time limit.

Parameter Problems Received/Transmitted

The number of ICMP Parameter Problem messages received/sent. Parameter Problem messages indicate a syntactic or semantic error in an IP header.

Source Quench Received/Transmitted

The number of ICMP Source Quench messages received/sent. Source Quench messages provide rudimentary flow control; they request a reduction in the rate of sending traffic on the network.

Redirects Received/Transmitted

The number of ICMP Redirect messages received/sent. Redirect messages advise that there is a better route to a particular destination.

Echo Requests (PINGs) Received/Transmitted

The number of ICMP Echo (request) messages received/sent. Echo messages are probably the most visible ICMP messages. They test the communication path between network entities by asking for Echo Reply response messages.

Echo Replies (PINGs) Received/Transmitted

The number of ICMP Echo Reply messages received/sent. Echo Reply messages are sent in response to Echo messages, to test the communication path between network entities.
