Network QoS Policy Command Reference
ler-use-dscp
Syntax [no] ler-use-dscp
Context config>qos>network>ingress
Description This command is used to enable tunnel QoS mapping on all ingress network IP interfaces the network-
qos-policy-id is associated with. The command may be defined at anytime after the network QoS
policy has been created. Any network IP interfaces currently associated with the policy will
immediately start to use the internal IP ToS field of any tunnel terminated IP routed packet received
on the interface, ignoring any QoS markings in the tunnel portion of the packet.
This attribute provides the ability to ignore the network ingress QoS mapping of a terminated tunnel
containing an IP packet that is to be routed to a base router or VPRN destination. This is advantageous
when the mapping for the tunnel QoS marking does not accurately or completely reflect the required
QoS handling for the IP routed packet. When the mechanism is enabled on an ingress network IP
interface, the IP interface will ignore the tunnel's QoS mapping and derive the internal forwarding
class and profile based on the precedence or DiffServe Code Point (DSCP) values within the routed IP
header ToS field compared to the Network QoS policy defined on the IP interface.
The default state is not to enforce tunnel termination IP routed QoS override within the network QoS
policy.
The no form of the command removes tunnel termination IP routed QoS override from the network
QoS policy and all ingress network IP interfaces associated with the policy.
Default no ler-use-dscp
lsp-exp
Syntax lsp-exp lsp-exp-value fc fc-name profile {in | out}
no lsp-exp lsp-exp-value
Context config>qos>network>ingress
Description
This command creates a mapping between the LSP EXP bits of the network ingress traffic and the
forwarding class.
Ingress traffic that matches the specified LSP EXP bits will be assigned to the corresponding
forwarding class. Multiple commands can be entered to define the association of some or all eight LSP
EXP bit values to the forwarding class. For undefined values, packets are assigned to the forwarding
class specified under the default-action command.
The no form of this command removes the association of the LSP EXP bit value to the forwarding
class. The default-action then applies to that LSP EXP bit pattern.
Default none
