| aristaTapaggMIB |
1.3.6.1.4.1.30065.3.31 |
| This MIB contains information related to the tapagg feature
that is implemented on specific Arista switches running EOS.
On specific Arista devices, EOS offers a powerful solution for
network performance monitoring. These devices have significant
bandwidth capacity and different port or interface speed options
for a non-blocking monitoring solution. This specific EOS
feature is called 'TAP aggregation' or 'tapagg'. These devices are
typically capable of performing packet classification in
hardware as well, and that can be used to steer the monitored
traffic as desired, directly to the right set of external tools.
With the tapagg feature, the Arista switching device is first
put into an exclusive mode to do the desired packet replication.
In this mode, normal switching functions like bridging, routing
etc. are disabled.
Interfaces are categorized into 'tap' (they receive the traffic
that is required to be replicated) and 'tool' (they transmit the
replicated packet out and are in the path towards the monitoring
tool).
Furthermore, the tapagg feature allows users to configure
classification rules via the policy-map construct so that the
mirrored traffic can be steered appropriately.
Another layer of indirection that is provided is called
aggregation-groups. Tap and tool interfaces can be part of a
specific aggregation group, and that allows for a powerful way
to express replication or mirroring rules. Policies can change
the aggregation group for specific set of packets, and that can
be used to steer traffic out of desired tool interfaces as
appropriate.
This MIB provides information related to the tapagg feature. |

| aristaTapaggPolicyTable |
1.3.6.1.4.1.30065.3.31.1.1 |
| This table contains information about the tapagg policies
configured in the system.
The configuration construct 'policy-map type tapagg' is used
to create and maintain these policies. Once a policy is defined it
can be applied against the appropriate interfaces. The basic idea
behind these policies is to classify packets (IP or IPv6 packet
information or L2 packet information etc.) and on relevant matches
take specific actions. One example of an action is to set
the aggregation-group for the matched traffic.
This table provides a simple list of tapagg policies, and a
subsequent table provides additional details for each policy. |

1.3.6.1.4.1.30065.3.31.1.2 |
| This table contains additional details about the tapagg policies
configured in the system.
Within a policy the packet match criteria and set action are
provided using 'class-maps'. Internally the device maintains
useful state, including counters, for each class-map.
However, a simple match criteria along with a set
action can be provided without the class-map construct as well. In
this case, the device will automatically construct an internal/unique
class-map for this specific match/set configuration.
As mentioned above, counters are maintained for matched packets.
However, this requires explicit configuration so that the counter
resources in the hardware can be enabled.
There will be a conceptual row in this table for every class-map
configured inside a policy. |

| aristaTapaggPolicyClassEntry |
1.3.6.1.4.1.30065.3.31.1.2.1 |
| A single conceptual row containing information about a
specific class-map within a policy.
A conceptual row is identified by the following components:
1. A bounded-length identifier that corresponds to the name of
the policy.
2. An index that identifies the sequence in which match
criteria are evaluated at run time. The index values may not be
consecutive. |

As described earlier, a simple match/set configuration is possible
without creating a class-map construct. In that the case, the
device manages relevant state by maintaining an internal/unique
class-map name. |
