ciscoDlswTConnOperPartnerVersion
cisco Data Link Switching T Connection Operation Partner Version
1.3.6.1.4.1.9.10.9.1.2.3.1.9
This value identifies which version (first octet) and release (second octet) of the DLSw standard is supported by this partner DLSw. This information is obtained from a DLSw capabilities exchange message received from the partner DLSw. A string of zero length is returned before a Capabilities Exchange message is received, or if one is never received. A conceptual row with a ciscoDlswTConnOperState of `connected' but a zero length partner version indicates that the partner is a non-standard DLSw partner. If an implementation chooses to keep ciscoDlswTConnOperEntrys in the `disconnected' state, this value should remain unchanged.
