XII. Configuring/disabling LR
Perform the following configuration in traffic behavior view.
Table 3-45 Configure/disable LR
Configure LR
Disable LR
The policy that contains LR behaviors can only be applied to the outgoing direction of
interfaces.
The LR configured using the lr or lr percent command will replace the previous LR
configuration, if there is any.
When configuring LR with policy embedding, observe the following rules:
For a parent policy, you can configure queuing in its child policy only when it has
been configured with LR using the lr or lr percent command. In this case, the
queue length in the child policy applies. (You can configure queue length using the
qos gts command.) If the child policy has no queuing configuration, traffic is put in
a FIFO queue whose length is fixed to 200. You cannot delete the LR setting in the
parent policy after queuing is configured in the child policy.
When configuring LR on an ATM or FR interface, consider the following:
LR can be applied to ATM PVCs but not to ATM interfaces.
On FR PVCs, you can configure the lr command but not the lr percent command.
On an FR interface configured with the fr traffic-shaping command, you cannot
configure LR.
LR cannot be configured in a child policy.
