ExtremeWare XOS 11.5 Command Reference Guide
450
show cfm statistics
show cfm {<domain_name> {<association_name> {ports <port_list>} {end-point
[inward-facing | outward-facing] | filter}}} statistics
Description
Displays the MP statistics.
Syntax Description
Default
N/A.
Usage Guidelines
The system displays the software counters; that is, packets blocked by hardware are not included.
To clear these counters, use the
clear counters command.
This command displays the following information for the statistics:
● The name of the domain and association
● Port number
● MP and type
● Number of packets blocked because the MA level in the packet is superior to the MA level configured
on the specified port (A CCM is forwarded when the embedded MA level is numerically equal to or
lower than the configured MA level on the switch; that is, a domain configured with an MA level of 5
forwards CCMS with levels 0, 1, 2, 3,4, and 5; CCMs with a level of 6 or 7 are blocked.)
● Number of packets received with an unknown CFM message type
Example
The following command displays the CCM databases on the switch:
show cfm statistics
domain_name Enter the name of the domain for which you want to display the MP statistics.
association_name Enter the name of the association for which you want to display the MP
statistics.
port_list Enter the ports in the domain/association for which you want to display the MP
statistics.
inward-facing Enter this to display the statistics for the inward-facing MEP for the specified
MA.
outward-facing Enter this to display the statistics for the outward-facing MEP for the specified
MA.
filter Enter this to display the statistics for the CFFs for the specified MA.
