  5. Supporting MEP/MIP functions by MEP/MIP resources • EVC and PW MEP functions are supported by MEP resources • A MEP resource can be assigned to an EVC or PW transport entity • A MEP resource can be configured to generate/process Ethernet VLAN OAM or MPLS-TP PW or LSP (for PW Segment) OAM • EVC and PW MIP functions are supported by MIP resources • A MIP resource can be assigned to an EVC or PW transport entity • A MIP resource can be configured to generate/process Ethernet VLAN OAM or MPLS-TP PW OAM • EVP and LSP MEP functions are supported by MEP resources • A MEP resource can be assigned to an EVP or LSP transport entity • A MEP resource can be configured to generate/process Ethernet VLAN OAM or MPLS-TP LSP OAM • EVP and LSP MIP functions are supported by MIP resources • A MIP resource can be assigned to an EVP or LSP transport entity • A MIP resource can be configured to generate/process Ethernet VLAN OAM or MPLS-TP LSP OAM
