Debugging Resilient ARP
Configuration
Perform the following configuration in System View.
Table 84 Enabling/Disabling Resilient ARP Function
Operation
Enable resilient ARP function
Disable resilient ARP function
By default, resilient ARP function is enabled.
If you are attempting to stop the Switch from transmitting packets, you need to
disable all features which may generate packets. By default these are:
DHCP
■
Resilient ARP
■
Spanning Tree
■
Configuring Resilient ARP Packet-sending VLAN Interface
You must configure the VLAN interface corresponding to the redundant links
which connect the XRN fabric with other devices, to make resilient ARP operate
normally. Then if intra-fabric connections are broken, resilient ARP packets can be
sent through these VLAN interfaces corresponding to the redundant links, to
determine if the system works as a layer 3 or layer 2 device.
You can use the following command to configure through which VLAN interface
resilient ARP packet is sent. The system provides a default VLAN interface to send
resilient ARP packets.
Perform the following configuration in System View.
Table 85 Configuring/Deleting Resilient ARP Packet-sending VLAN Interface
Operation
Configure resilient ARP
packet-sending VLAN interface
Delete resilient ARP
packet-sending VLAN interface
By default, the system sends resilient ARP packets through VLAN interface 1.
Note that you only specify resilient ARP packet-sending VLAN interfaces, and any
VLAN interface can receive resilient ARP packets.
After the above configurations are completed, you can enter the
command in any view to view the running of resilient ARP function and to further
check configuration results.
