MPLS Module Installation and User Guide
Description
Enables or disables the propagation of the IP
time-to-live (TTL) field for routed IP packets.
Specify one of the following:
enabled — Each LSR is viewed as a router
I
hop from an IP TTL perspective.
disabled — The LSP is viewed as a
I
point-to-point link between the ingress LSR
and the egress LSR.
Configures MPLS-specific QoS mappings.
Specify one of the following QoS mappings:
dot1p-to-exp — Mappings are used in
I
performing the ingress LSR function. The
value in this priority field is set based on the
QoS classification performed by the ingress
I/O module.
exp-to-dot1p — Mappings are used when
I
performing label swapping as an intermediate
LSR and when performing the egress LSR
function.
Configures the IP MTU for frames transmitted
onto MPLS LSPs via the specified egress VLAN.
The range is 42 to 9190 (using jumbo frame
sizes). The default setting is 4 less than the IP
MTU value. By default, the IP MTU value is 1500
bytes, so the default MPLS MTU is 1496 bytes.
Disables MPLS on the switch. Disabling MPLS
causes all LSPs to be released and all LDP
neighbor sessions to be terminated.
Enables MPLS on the switch. By default, MPLS
is disabled.
Displays MPLS configuration information for one
or all VLANs. Omitting the vlan keyword,
displays information for all VLANs.
