display ip urpf
Use display ip urpf to display uRPF configuration.
Syntax
MSR1000/MSR2000/MSR3000:
display ip urpf [ interface interface-type interface-number ]
MSR4000:
display ip urpf [ interface interface-type interface-number ] [ slot slot-number ]

Parameters
interface interface-type interface-number: Specifies an interface by its type and number.
slot slot-number: Specifies a card by slot number. (MSR4000)
Usage guidelines
To display uRPF configuration on an interface, check whether the interface is a global interface:
• If it is a global interface, specify the card where the interface resides. If you do not specify the
option, the command displays uRPF configuration for the MPU. A global interface has a
one-dimensional number, such as VLAN-interface 10.
• If it is not a global interface, you do not need to specify the card for the command to display the
interface uRPF configuration. A non-global interface has a multiple-dimensional number, such as
GigabitEthernet 2/1/1.
Examples
# Display uRPF configuration for the card in slot 3. (MSR4000)
<Sysname> display ip urpf interface gigabitethernet 2/1/1 slot 3
