interface and any corresponding non-switch routes are automatically removed.
•
Hardware Settings
In some circumstances it may be necessary to change hardware settings for an interface. The
available options are:
i.
The speed of the link can be set. Usually this is best left as
Auto
.
ii.
The MAC address can be set if it needs to be different to the MAC address built into the
hardware. Some ISP connections might require this.
•
Virtual Routing
To implement
virtual routing
where the routes related to different interfaces are kept in
separate routing table, there are a number of options:
i.
Make the interface a member of all routing tables. This option is enabled by default and
means that traffic arriving on the interface will be routed according to the
main
routing
table. Routes for the interface IP will be inserted into all routing tables.
ii.
The alternative to the above is to insert the route for this interface into only a specific
routing table. The specified routing table will be used for all route lookups unless
overridden by a routing rule.
•
Automatic Route Creation
Routes can be automatically added for the interface. This addition can be of the following
types:
i.
Add a route for this interface for the given network. This is enabled by default.
ii.
Add a default route for this interface using the given default gateway. This is enabled by
default.
•
MTU
This determines the maximum size of packets in bytes that can be sent on this interface. By
default, the interface uses the maximum size supported.
•
High Availability
There are two options which are specific to high availability clusters:
i.
A private IPv4 address can be specified for this interface.
ii.
An additional option is to disable the sending of HA cluster heartbeats from this
interface.
•
Quality Of Service
The option exists to copy the IP
DSCP
precedence to the VLAN priority field for any VLAN
packets. This is disabled by default.
