Cisco Cisco ONS 15454 SDH Multiservice Provisioning Platform (MSPP) 릴리즈 노트

In Software Release 4.6 and later, the ML-Series card supports combining VLAN-transparent services 
and one or more VLAN-specific services on the same port. All of these VLAN-transparent and 
VLAN-specific services can be point-to-point or multipoint-to-multipoint. This allows a service 
provider to combine a VLAN-transparent service, such as IEE 802.1Q tunneling (QinQ), with 
VLAN-specific services, such as bridging specific VLANs, on the same customer port. For example, one 
customer VLAN can connect to Internet access and the other customer VLANs can be tunneled over a 
single provider VLAN to another customer site, all over a single port at each site. VLAN-transparent 
service is also referred to as Ethernet Wire Service (EWS). VLAN-specific service is also referred to as 
Ethernet Relay Multipoint Service (ERMS).

EoMPLS provides Ethernet services across the MPLS backbone and core network. The ML series 
EoMPLS microcode image supports both VLAN and Port based point to point Ethernet tunnels across 
the MPLS network. The ML series EoMPLS feature enables Ethernet service delivery on the access 
SONET/SDH network over the RPR and transport that service across the core MPLS network without 
the need to create a separate bridged access network.

Release 4.6.x MST Protocol Tunneling allows Multi-Spanning-Tree on an external bridge to be used to 
enable a redundant pair of ML-series cards without requiring a spanning-tree instance per VLAN.

With Release 4.6.x SDH supports TL1 test access. For details, see the Cisco ONS 15454 SDH TL1 Test 
Access Quick Start Guide.
