# Cisco Nexus NX-OS and DCNM XML APIs - Cisco Live 2008

Since I am at Cisco Live Networks all week, and I take notes anyway, I thought I would share them with you.

## NX-OS / DCNM XML API Fundamental Technology

Netconf - platform for secure communication of XML data between DCNM / NX-OS and management station.

XML, using clear text tags, creates a self describing API. This is necessary because of the confusion and unnecessary complexity inherent in the current SNMP MIB based structure commonly in place today.

Webservices API = SOAP/XML over HTTPS.

## Netconf/XML on NX-OS capabilities

* Must be run over SSH
* Maximum of eight concurrent NetConf Sessions per Nexus virtual device context
* Every single CLI capability is assigned a XML tag

## JMS is supported in DCNM as well as NETCONF

* Native integration with IBM Message Queue
