Context config>eth-tunnel>lag-emulation>access
Description This command configures how the Ethernet Tunnel group SAP queue and virtual scheduler buffering and
rate parameters are adapted over multiple active MDAs.
The no form of the command reverts the default.
Default no adapt-qos
Parameters distribute — Each MDA will receive a fraction of the SAP and scheduler parameters.
link — The Ethernet Tunnel group will create the SAP queues and virtual schedulers with the actual param-
eters on each MDA.
port-fair — Places the LAG instance into a mode that enforces QoS bandwidth constraints in the following
manner:
• All egress QoS objects associated with the LAG instance are created on a per port basis
• Bandwidth is distributed over these per port objects based on the proportion of the port’s bandwidth
relative to the total of all active ports bandwidth within the LAG
• The inc-egr-hash-cfg behavior is automatically enabled allowing the system to detect objects that
hash to a single egress link in the lag and enabling full bandwidth for that object on the appropriate
port
A LAG instance that is currently in adapt-qos link mode may be placed at any time in port-fair mode.
Similarly, a LAG instance currently in adapt-qos port-fair mode may be placed at any time in link mode.
However, a LAG instance in adapt-qos distribute mode may not be placed into port-fair (or link) mode
while QoS objects are associated with the LAG instance. To move from distribute to port-fair mode
either remove all QoS objects from the LAG instance or remove all member ports from the LAG
instance.
per-fp-ing-queuing
Syntax [no] per-fp-ing-queuing
Context config>eth-tunnel>lag-emulation>access
Description This command configures whether a more efficient method of queue allocation for Ethernet Tunnel Group
SAPs should be utilized.
The no form of the command reverts the default.
Default no per-fp-ing-queuing
path-threshold
Syntax path-threshold num-paths
no path-threshold
Context config>eth-tunnel>lag-emulation
