R3303-HP HSR6800 Routers MPLS Command Reference

229
revertive: Enables support for switchback. With this keyword specified, when the primary VC recovers,
traffic is switched from the backup VC back to the primary VC automatically. If you do not specify this
keyword, traffic will not be switched back automatically.
wtr-time wtr-time: Specifies the switchback delay time. When the primary VC recovers, the device waits
for the switchback delay time before switching the traffic from the backup VC back to the primary VC. T
The value range for the wtr-time argument is 1 to 720 minutes, and the default is 30 minutes.
Usage guidelines
This command is supported only on routers with SAP-4EXPs.
The access mode refers to how a PE treats the outer VLAN tag carried in packets received from a CE, and
how the PE sends packets to the CE. Two access modes are available:
• VLAN mode—The Ethernet packets sent from a CE to a PE carry a VLAN tag. The PE treats the
VLAN tag as a P-Tag, which is a service delimiter that the service provider adds to the packets to
identify the user. The PE also adds a P-tag into the packets to be sent to the CE.
• Ethernet mode—If the Ethernet packets sent from a CE to a PE contain a VLAN tag, the PE treats the
VLAN tag as a U-Tag, which is the VLAN tag of the user network. When the PE sends packets to the
CE, it does not add a P-tag into the packets.
The MTU specified by this command is advertised through LDP and used for PW negotiation.
This command is available for service instances with the ID in the range of 1 to 4094.
Examples
# For service instance 100, create a Martini VC and specify the matching external VLAN tag as 100.
