Configuring Ip Routes Settings; Port Preferences - Cisco TELEPRESENCE ISDN GATEWAYS 2.0 Online Help Manual

Configuring IP routes settings

You need to set up one or more routing settings to control how IP traffic flows in and out of the ISDN
gateway.
It is important that these settings are configured correctly, or you may be unable to make calls or access
the web interface.
To configure the route settings, go to Network > Routes.

If both Ethernet ports are enabled, it is necessary to specify which port is used in certain special
circumstances. Make the appropriate selections described below; click Apply changes to make any
changes take effect.
Field
Field description
Default gateway The IP address to which the ISDN gateway
preference will send packets in the absence of more
specific routing (see
configuration). Therefore, it only makes
sense to have precisely one default
gateway, even though different default
gateways may have been configured for
Ports A and B. Use this option to decide
which port's default gateway configuration to
use as the unit's default gateway.
Name server The IP address to which the ISDN gateway
(DNS)
will send requests to look up unrecognized
preference host names in order to determine their
corresponding IP addresses. Only one
name server (and associated secondary
name server) may be used, even though
different name servers may have been
configured for Ports A and B. Use this
option to decide which port's name server
configuration to use as the unit's name
server.

Usage tips
If Ethernet Port B is disabled, you
cannot specify that port as the
default gateway preference.
Selecting Port B as default gateway
preference then disabling Port B will
cause the preference to revert to
Port A.
If Ethernet Port B is disabled, you
cannot specify that port as the name
server preference.
Selecting Port B as name server
preference then disabling Port B will
cause the preference to revert to
Port A.
