Owner Preemption?
Enables or disables master preemption. When enabled, if the virtual router group is in
backup mode but has a higher priority than the current master, this virtual router will
preempt the lower priority master and assume control. Note that even when preem is
disabled, this virtual router will always preempt any other master if this switch is the
owner (the IP interface address and virtual router addr are the same). By default, this
option is enabled.
Track other IP interface?
When enabled, the priority for this virtual router will be increased for each other IP
interface active on this switch. An IP interface is considered active when there is at least
one active port on the same VLAN. This helps elect the virtual routers with the most
available routes as the master. This command is disabled by default.
Track VLAN switch ports?
When enabled, the priority for this virtual router will be increased for each active port on
the same VLAN. A port is considered ―active‖ if it has a link and is forwarding traffic.
This helps elect the virtual routers with the most available ports as the master. This
command is disabled by default.
Domain Name System Configuration
To display the following form, select Layer 3 > Domain Name System.
The Domain Name System (DNS) Menu is used for defining the primary and secondary DNS servers on your
local network, and for setting the default domain name served by the switch services. DNS parameters must
be configured prior to using hostname parameters with the ping, traceroute, and tftp commands.
The following table describes the Domain Name System Configuration controls:
