1.2.1 Enabling/Disabling the Function to Ping the Virtual IP Address

This operation enables or disables the ping response for the virtual IP address of the
backup group. The standard VRRP protocol does not support the ping response, then
the user cannot judge with ping command whether an IP address is used by the
backup group. If you configure the IP address for the host same as the virtual IP
address of the backup group, then all messages in this segment will be forwarded to
the host.
So the Quidway S6500 Series Ethernet Switches provide the ping function.
You can use the following commands to enable and disable the ping function.
Perform the following configuration in system view.
Table 1-1 Enable/disable the ping function
Enable to ping the virtual IP address
Disable to ping the virtual IP address
By default, the function to ping the virtual IP address is disabled.
Note that you must set the ping function before configuring the backup group. If a
back group has been established already, this configuration is not allowed.
1.2.2 Setting Correspondence Between Virtual IP Address and MAC
Address
This operation sets the virtual IP address to correspond to the virtual MAC address. In
the standard protocol of VRRP, the virtual IP address of the backup group
corresponds to the virtual MAC address, and guarantee correct data forwarding in the
sub-net.
Due to the chips installed, some switches support matching one IP address of a
routing interface to multiple MAC addresses.
The S6500 series switches not only guarantee correct data forwarding in the sub-net,
but also support such a function: you can choose to match the virtual IP address of
the backup group with the real MAC address or virtual MAC address of the routing
interface.
The following commands can be used to set correspondence between the virtual IP
address and the MAC address.
Perform the following configuration in system view.
