Configure Service Sdp Path-Mtu - Alcatel-Lucent OmniSwitch 6850-48 Cli Reference Manual

Virtual Private LAN Service (VPLS) Commands

configure service sdp path-mtu

Configures the administrative Maximum Transmission Unit (MTU) value for the SDP. This value speci-
fies the largest service frame size that the SDP can transmit to the far-end router without dropping packets
or requiring IP fragmentation.
configure service sdp sdp-ip path-mtu bytes
configure service sdp sdp-ip no path-mtu
Syntax Definitions
sdp-id
bytes
Defaults
By default, the path MTU for the SDP is set to zero. This specifies that the MTU value is dynamically
calculated from the corresponding tunnel.
Platforms Supported
OmniSwitch 9000E
Usage Guidelines
•
Use the no form of this command to revert the path MTU to the default value of zero.
•
If the physical MTU on an egress interface or channel indicates the next hop on an SDP path cannot
support the current path MTU, the operational path MTU on that SDP is modified to a value that can
be transmitted without fragmentation.
•
If the service MTU is larger than the path MTU, the SDP binding for the service is placed in an inoper-
ative state. If the service MTU is equal to or less than the path MTU, then the SDP binding is placed in
an operational state.
Examples
-> configure service sdp 10 path-mtu 1514
-> configure service sdp 10 no path-mtu
