DESCRIPTION
Type the domain name of the Telia login server, for example login1.telia.com.
The Telia server logs the Vantage CNM out if the Vantage CNM does not log in
periodically. Type the number of minutes from 1 to 59 (30 default) for the Vantage
CNM to wait between logins.
Select this option If your ISP did not assign you a fixed IP address. This is the
default selection.
Select this option If the ISP assigned a fixed IP address.
Enter your WAN IP address in this field if you selected Use Fixed IP Address.
Enter the IP subnet mask (if your ISP gave you one) in this field if you selected Use
Fixed IP Address.
Enter the gateway IP address (if your ISP gave you one) in this field if you selected
Use Fixed IP Address.
RIP (Routing Information Protocol) allows a router to exchange routing information
with other routers. The RIP Direction field controls the sending and receiving of
RIP packets.
Choose Both, None, In Only or Out Only.
When set to Both or Out Only, the Vantage CNM will broadcast its routing table
periodically.
When set to Both or In Only, the Vantage CNM will incorporate RIP information
that it receives.
When set to None, the Vantage CNM will not send any RIP packets and will ignore
any RIP packets received.
By default, RIP Direction is set to Both.
The RIP Version field controls the format and the broadcasting method of the RIP
packets that the Vantage CNM sends (it recognizes both formats when receiving).
Choose RIP-1, RIP-2B or RIP-2M.
RIP-1 is universally supported; but RIP-2 carries more information. RIP-1 is
probably adequate for most networks, unless you have an unusual network
topology. Both RIP-2B and RIP-2M sends the routing data in RIP-2 format; the
difference being that RIP-2B uses subnet broadcasting while RIP-2M uses
multicasting. Multicasting can reduce the load on non-router machines since they
generally do not listen to the RIP multicast address and so will not receive the RIP
packets. However, if one router uses multicasting, then all routers on your network
must use multicasting, also. By default, the RIP Version field is set to RIP-1.
Choose None (default), IGMP-V1 or IGMP-V2. IGMP (Internet Group Multicast
Protocol) is a network-layer protocol used to establish membership in a Multicast
group – it is not used to carry user data. IGMP version 2 (RFC 2236) is an
improvement over version 1 (RFC 1112) but IGMP version 1 is still in wide use. If
you would like to read more detailed information about interoperability between
IGMP version 2 and version 1, please see sections 4 and 5 of RFC 2236.
