About the IP addresses
Management IP address
The Management IP address (MIP) identifies the Nortel SNAS 4050 in the
network. In a multi-Nortel SNAS 4050 solution, the MIP is an IP alias to one of
the Nortel SNAS 4050 devices in the cluster and identifies the cluster. The MIP
always resides on a master Nortel SNAS 4050 device. If the master Nortel
SNAS 4050 that currently holds the MIP fails, the MIP automatically migrates to
a functional master Nortel SNAS 4050. In order to configure the Nortel
SNAS 4050 or Nortel SNAS 4050 cluster remotely, you connect to the MIP using
Telnet (for the CLI) or SSH (for the CLI or the SREM).
Portal Virtual IP address
The portal Virtual IP address (pVIP) is the address assigned to the Nortel
SNAS 4050 device’s web portal server. The pVIP is the address to which clients
connect in order to access the Nortel SNA network. While the client is in the Red
VLAN and the Nortel SNAS 4050 is acting as DNS server, the pVIP is the DNS
server IP address. Although it is possible to assign more than one pVIP to a Nortel
SNAS 4050 device, Nortel recommends that each Nortel SNAS 4050 have only
one pVIP. When the Nortel SNAS 4050 portal is configured as a captive portal,
the pVIP is used to load balance logon requests.
