26.2.2
Use of OAM, Control and Media Subnets by Mediant 8000
Boards
The Mediant 8000 supports multiple subnets for OAM, call control and media traffic.
OAM traffic mainly passes through the SC boards, located in Slots 1 and 2. This
includes SNMP traffic between the Mediant 8000 and EMS (or 3
rd
party SNMP
managers), as well as SSH traffic used for connecting to the Mediant 8000 CLI
interface. Spcecific OAM traffic also passes through the Mediant 8000 boards, located
in slots 3-8 and 10-18 – for example, the HTTPS traffic used for connecting to the
WEB-based debug interface on the Media Gateway boards.
Media and Control traffic passes through the Media Gateway boards only. All VoP-
related communication is performed directly between the Gateway boards and the
corresponding external entities (i.e. Soft Switches, Media Gateway and Signaling
Gateways). The SC boards are not involved in this type of traffic in any possible way.
26.2.3
Connecting Mediant 8000 to IP Network
The Mediant 8000 must be connected to each relevant subnet existing on site.
Connection details depend on the amount of available subnets and the type of their
separation. In the simplest default configuration, when a single subnet is used for all
types of IP traffic, two uplinks – one from each Ethernet Switch board (residing in slots
9 and 19) – should be connected to the external equipment. See 'External Layer 3
Ethernet Switches or Routers' in Section 'Connecting the Mediant 8000 to the IP
Network' on page
for details on how the external equipment should be configured.
When multiple subnets are available, connection options depend on whether subnets
are separated via the use of separate network interfaces (cables) or via the use of the
tagged VLANs. In the former case (subnets separated via the use of separate network
interfaces), multiple network cables should be connected to each ES board – one
cable per each relevant subnet. In the latter case (subnets separated via the use of
tagged VLANs) – a single cable should be connected to each ES board for multiple
subnets.
In any case, to ensure a fully redundant IP network connection, make sure that for
each network cable connected to the ES board in slot 9, a redundant cable is
connected to the corresponding port on the ES board in slot 19.
