sdpBindCpmProtEthCfmMonitorFlags
1.3.6.1.4.1.6527.3.1.2.4.4.4.1.52
The value of sdpBindCpmProtEthCfmMonitorFlags specifies whether or not
to apply rate limiting (using the tmnxCpmProtEthCfmPolTable
configuration) to Ethernet Connectivity Fault Management (Eth-CFM)
packets served by the SDP binding. Two associated options are also
specified.
Five combinations of flag values are supported, as shown in the
following table.
Flag Value (0=Disabled, 1=Enabled)
------------------------------------- -----------------------------
'ethCfmMonitor(0)' 0 0 0 0 1 1 1 1
'ethCfmMonitorAggregate(1)' 0 0 1 1 0 0 1 1
'ethCfmMonitorCommittedAccessRate(2)' 0 1 0 1 0 1 0 1
------------------------------------- -----------------------------
Supported Combination? Y N N N Y Y Y Y
If 'ethCfmMonitor(0)' is disabled, Eth-CFM rate limiting is disabled on
this SDP binding.
If 'ethCfmMonitor(0)' is enabled, Eth-CFM rate limiting is enabled on
this SDP binding. Excess packets are discarded. The configured
information used to perform the Eth-CFM rate limiting (e.g. the rate
limit(s)) resides in the tmnxCpmProtEthCfmPolTable row(s) indexed by
the SDP binding's sdpBindCpmProtPolicyId.
At most one of 'ethCfmMonitor(0)' and sdpBindCpmProtMonitorMac can be
enabled for this SDP binding.
The flags 'ethCfmMonitorAggregate(1)' and
'ethCfmMonitorCommittedAccessRate(2)' adjust the behavior of Eth-CFM
rate limiting. Therefore, they are only significant if Eth-CFM rate
limiting is enabled (i.e. when 'ethCfmMonitor(0)' is enabled). The
remainder of this DESCRIPTION assumes 'ethCfmMonitor(0)' is enabled.
If 'ethCfmMonitorAggregate(1)' is disabled, the applicable Eth-CFM
packet rate limit (tmnxCpmProtEthCfmPolRateLimit) applies per peer
(i.e. on a source MAC address basis). For example, if the SDP
binding's rate limit for all Eth-CFM packets is 100 packets/sec, and
two peers are served by the SDP binding, then 100 Eth-CFM packets/sec
from each peer is within the limit.
If 'ethCfmMonitorAggregate(1)' is enabled, the applicable Eth-CFM
packet rate limit (tmnxCpmProtEthCfmPolRateLimit) applies to the
aggregated traffic flow. For example, if the SDP binding's rate limit
for all Eth-CFM packets is 100 packets/sec, and two peers are served by
this SDP binding, then the combined rate of the two peers cannot exceed
100 packets/sec.
'ethCfmMonitorCommittedAccessRate(2)' controls the interaction
between two features: Eth-CFM rate limiting, and overall rate limiting
(as configured using tmnxCpmProtPolOverallRateLimit).
If 'ethCfmMonitorCommittedAccessRate(2)' is disabled, an Eth-CFM
packet is subjected to two rate limits, in the following order.
a) The applicable tmnxCpmProtEthCfmPolRateLimit is applied, as
described above. If the packet exceeds the limit, it is discarded.
Otherwise...
b) The SDP binding's tmnxCpmProtPolOverallRateLimit (which is applied
to Eth-CFM packets, and the other rate limited packet types) is
applied.
If 'ethCfmMonitorCommittedAccessRate(2)' is enabled, an Eth-CFM packet
is subjected to one rate limit: the applicable
tmnxCpmProtEthCfmPolRateLimit, as described above. Eth-CFM packets
are neither counted nor discarded when performing the
tmnxCpmProtPolOverallRateLimit rate limiting.
