Table 163 VRRP General Configuration controls Control Owner Preemption? Track other IP interface? Track VLAN switch ports? Descriptions 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. 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. 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: Table 164 Domain Name System Configuration controls Control Description Primary IP Address Secondary IP Address Default Domain Name Sets the IP address for your primary DNS server. Use dotted decimal notation. Sets the IP address for your secondary DNS server. If the primary DNS server fails, the configured secondary will be used instead. Enter the IP address using dotted decimal notation. Sets the default domain name used by the switch. For example: mycompany.com. Configuring the switch 196

Table 163

VRRP General Configuration controls

Control

Descriptions

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

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

commands.

The following table describes the Domain Name System Configuration controls:

Description

Primary IP Address

Sets the IP address for your primary DNS server. Use dotted decimal notation.

Secondary IP Address

Sets the IP address for your secondary DNS server. If the primary DNS server fails, the

configured secondary will be used instead. Enter the IP address using dotted decimal

notation.

Default Domain Name

Sets the default domain name used by the switch. For example:
