B-40APPENDIX B: CLI COMMAND DESCRIPTION

show icmp counters Shows the Input and Output Counters for ICMP. Two types of ICMP messages -

error and query messages - are sent to syslog hosts.

ICMP COUNTERS

INPUT COUNTERS

Messages - ICMP packets received.

Errors - ICMP packets received with errors.

Destination Unreachable - sum of ICMP messages received when a router cannot forward a packet to its specified destination

Time Exceeded - sum of ICMP messages generated by a router when time has exceeded or a timeout has occurred while waiting for a packet segment

Parameter Problems - sum of ICMP messages generated by a router when it encounters an error

Source Quench - sum of ICMP messages informing a host it should slow data transmission to ease congestion

Redirects - sum of ICMP messages concerning a router advertising a host of a better next hop

Echos - sum of ICMP request messages received, signifying transport system success

Echo Replies - sum of ICMP reply messages received, indicating transport system success

Timestamps - sum of ICMP request messages received seeking time from another machine for clock synchronization and estimated transit time purposes

Timestamp Replies - sum of ICMP timestamp reply messages

Address Masks - sum of ICMP Address Mask Reply messages

Address Mask Replies - sum of ICMP request messages concerning a host’s ability to gather network information

OUTPUT COUNTERS

Messages - total of ICMP messages transmitted

Errors - ICMP packets transmitted with errors

Destination Unreachable - sum of these messages sent

Time Exceeded - sum of these messages sent

Parameter Problems - sum of these messages sent

Source Quench - sum of these messages sent

Redirects - sum of these messages sent

Echos - sum of ICMP Echo (request) messages sent

Echo Replies - sum of these messages sent

Timestamps - sum of these messages sent
