Mediant 8000
26.2.4 Configuring IP Network Interfaces
The Mediant 8000 supports connection to the physically-separated subnets via the
use of separate network cables, each cable being connected to its own subnet. The
following physical network interfaces configurations are supported:
"One: OCM" – one network interface is uses for carrying all types of IP traffic,
including OAM (management), Call Control and Media traffic; subnet separation
is possible within the interface via the use of VLAN tagging.
"Two: OC & M" – two network interfaces are used, one carrying OAM
(management) and Call Control traffic and another one carrying Media traffic;
additional subnet separation (on both interfaces) is possible via the use of VLAN
tagging.
"Two: O & CM" – two network interfaces are used, one carrying OAM
(management) traffic and another one carrying Call Control and Media traffic;
additional subnet separation (on "CM" network interface) is possible via the use
of VLAN tagging.
"Three: O & C & M" – three network interfaces are used, each one dedicated to a
corresponding traffic type – OAM (management), Call Control and Media
correspondingly; additional sub-subnet separation is possible via the use of VLAN
tagging (e.g. for multiple Media subnets).
"Two: OLAN & WAN" – two network interfaces are used, one carrying OAM
(management), Call Control and Media traffic ("OLAN" interface) and another one
carrying Call Control and Media traffic ("WAN" interface); additional subnet
separation (on both interfaces) is possible via the use of VLAN tagging.
"Three: O & LAN & WAN" – three network interfaces are used, one carrying OAM
(management) traffic and another two carrying both Call Control and Media traffic
("LAN" and "WAN" interfaces); additional subnet separation (on "LAN" and
"WAN" interfaces) is possible via the use of VLAN tagging.
See 'Ethernet ports allocation on ES boards' on page 217 for the exact numbers of
network interfaces (ES board ports) used for connecting Mediant 8000 to the external
network equipment in each network interfaces configuration.
