R2511-HP MSR Router Series MPLS Command Reference(V5)

336
interface-number.subnumber: Specifies the number of an access VE subinterface. The interface-number
argument specifies the number of an access VE interface, in the range of 1 to 8192. The subnumber
argument specifies the number of a subinterface created on the access VE interface, in the range of 0 to
1023.
Usage guidelines
An access VE interface in a VE group cannot be directly deleted. To delete it, remove it from the VE group
first.
When the packets entering the MPLS L3VPN or IP backbone carry VLAN tags, you must create a
subinterface on the access VE interface to terminate the VLAN tags. For more information about VLAN
termination, see Layer 2—LAN Switching Configuration Guide.
Deleting an access VE interface also deletes all subinterfaces on the interface.
Before you create an access VE subinterface, the corresponding access VE interface must already exist.
Examples
# Create access VE interface VE-L3VPN-Access 100, and enter access VE interface view.
<Sysname> system-view
[Sysname] interface ve-l3vpn-access 100
[Sysname-VE-L3VPN-Access100] quit
# Create access VE subinterface VE-L3VPN-Access 100.10, and enter access VE subinterface view.
[Sysname] interface ve-l3vpn-access 100.10
[Sysname-VE-L3VPN-Access100.10]
mtu

Use undo mtu to restore the default.

Parameters
size: Specifies the MTU on the interface, in bytes. The value range for the MTU depends on the interface
