mplsLdpEntityAtmMergeCap

Module: MPLS-LDP-ATM-MIB

OID (symbolic): MPLS-LDP-ATM-MIB::mplsLdpEntityAtmMergeCap

OID (numeric): 1.3.6.1.2.1.116.1.1.1.1.2

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-create

Description: Denotes the Merge Capability of this Entity. This is the EXACT value for the ATM Session Parameter, field M (for ATM Merge Capabilities). The ATM Session Parameter is an optional parameter in the Initialization Message.

The description from rfc3036.txt is:

'M, ATM Merge Capabilities Specifies the merge capabilities of an ATM switch. The following values are supported in this version of the specification:

Value Meaning

0 Merge not supported 1 VP Merge supported 2 VC Merge supported 3 VP & VC Merge supported

If the merge capabilities of the LSRs differ, then: - Non-merge and VC-merge LSRs may freely interoperate.

- The interoperability of VP-merge-capable switches with non- VP-merge-capable switches is a subject for future study. When the LSRs differ on the use of VP-merge, the session is established, but VP merge is not used.'

Please refer to the following reference for a complete description of this feature.

What is mplsLdpEntityAtmMergeCap?

This read-create enumerated value reports the ATM merge capability of this LDP entity as notSupported(0), vpMerge(1), vcMerge(2), or vpAndVcMerge(3), corresponding to LDP's ATM Session Parameter field M. An admin checks this to understand whether two LDP peers negotiating an ATM session can use VP merge, VC merge, or neither, since mismatched merge capability affects whether merging is used during session establishment. A value of vcMerge(2) tells the admin this LSR can combine multiple incoming ATM VCs into a single outgoing VC for a given FEC, reducing the number of labels needed.
