1.2.2 Enabling Users to Ping Virtual IP Addresses
You can configure whether the master switch responds to the received ICMP echo
requests, that is, whether the virtual IP address of a standby group can be successfully
pinged.
Follow these steps to enable a user to successfully ping the virtual IP addresses of
standby groups:

Caution:
Configure this function before creating a standby group. Otherwise, your configuration
will fail.
1.2.3 Configuring the Association Between Virtual IP Address and MAC
Address
After the virtual IP address of a standup group is associated with a MAC address, the
master switch takes the configured MAC address as the source MAC address of the
packets to be sent, so that the hosts in the internal network can learn the association
between the IP address and the MAC address and thus forward the packets to be
forwarded to the other network segments to the master switch properly.
There are two types of association between virtual IP address and MAC address:
z Virtual IP address is associated with virtual router MAC address
By default, a MAC address is created for a standby group after the standby group is
created, and the virtual IP address is associated with the virtual MAC address. With
such association adopted, the hosts in the internal network need not update the
association between IP address and MAC address when the master switch changes.
