Figure 82. ICMP window
Click on
ICMP
under the
Configuration Menu
to monitor access server ICMP statistics (see figure 82).
Block ICMP redirects (boxBLockIcmpRedirects)
Enables you to configure how the access server handles ICMP redirects. Enabling the access server to receive
redirected messages is generally considered a security breach.
The following options are available:
•
allowredirects(0)
•
stopredirects(1)
ICMP Receive/Send Messages window
The ICMP window displays the ICMP message counters. ICMP messages are displayed in the window as col-
umns comprising two types of messages:
•
Messages received by the access server (InMibVariable)
•
Messages sent by the access server (OutMibVariable)
The numbers following the parameters can be a good source of what is happening on the network to point out
potential problems. Both gateways (routers) and hosts can send ICMP messages.
Total Received/Sent (icmpInMsgs, imcpOutMsgs)
The number of ICMP messages the access server has received/sent. This number also includes ICMP messages
received/sent which have ICMP specific errors.
w/Errors (icmpInErrors, icmpOutErrors)
The number of ICMP messages which the access server has received/sent but are deemed to be faulty (for
example, bad ICMP checksums, bad length, or non-routable errors).
