Connectivity Fault Management
– 522 –
Use this command attribute to enable the link trace cache to store the results of
link trace operations initiated on this device. Use the CFM Transmit Link Trace
page (see "Transmitting Link Trace Messages") to transmit a link trace message.
Link trace responses are returned from each MIP along the path and from the
target MEP. Information stored in the cache includes the maintenance domain
name, MA name, MEPID, sequence number, and TTL value (see "Displaying
Fault Notification Settings").
◆ Link Trace Cache Hold Time – The hold time for CFM link trace cache entries.
(Range: 1-65535 minutes; Default: 100 minutes)
Before setting the aging time for cache entries, the cache must first be enabled
in the Link Trace Cache attribute field.
◆ Link Trace Cache Size – The maximum size for the link trace cache.
(Range: 1-4095 entries; Default: 100 entries)
If the cache reaches the maximum number of specified entries, or the size is set
to a value less than the current number of stored entries, no new entries are
added. To add additional entries, the cache size must first be increased, or
purged (see "Displaying Fault Notification Settings").
Continuity Check Errors
◆ Connectivity Check Config – Sends a trap if this device receives a continuity
check message (CCM) with the same maintenance end point identifier (MPID)
as its own but with a different source MAC address, indicating that a CFM
configuration error exists.
◆ Connectivity Check Loop – Sends a trap if this device receives a CCM with the
same source MAC address and MPID as its own, indicating that a forwarding
loop exists.
◆ Connectivity Check MEP Down – Sends a trap if this device loses connectivity
with a remote maintenance end point (MEP), or connectivity has been restored
to a remote MEP which has recovered from an error condition.
◆ Connectivity Check MEP Up – Sends a trap if a remote MEP is discovered and
added to the local database, the port state of a previously discovered remote
MEP changes, or a CCM is received from a remote MEP which as an expired
entry in the archived database.
MEP Up traps are suppressed when cross-checking of MEPs is enabled
18
because cross-check traps include more detailed status information.
Cross-check Errors
◆ Cross Check MA Up – Sends a trap when all remote MEPs in an MA come up.
An MA Up trap is sent if cross-checking is enabled
18
, and a CCM is received from
all remote MEPs configured in the static list for this maintenance association
19
.
18. Cross-checking must be enabled for this type of trap to be reported (see "Configuring CFM
Maintenance Associations").
