Cisco SNMP Driver Overview

The driver is implemented in openl2/switches/connect/snmp/cisco/connector.py

This Cisco driver inherits the standard MIB methods from SnmpConnector() for interface up/down and description.

For VLAN management, the Cisco driver implements the Old-Style Catalyst Way

Older Catalyst switches use the Cisco proprietary VTP MIB for vlan management. If VLANs are found in this MIB, the devices is assumed to use it, and self.use_vt_mib = True is set.
