cltcTunneledProtocolType
cltc Tunneled Protocol Type
1.3.6.1.4.1.9.9.246.1.3.1.1.1
Indicates tunneled protocol of the interface. If a BIT is set, then the value of the corresponding protocol is tunneled. Specifically, if the 'cdp(0)' BIT is set, then the Cisco Discovery Protocol PDU is tunneled; if the 'vtp(1)' BIT is set, then the VLAN Trunking Protocol PDU is tunneled; if the 'stp(2)' BIT is set, then the Spanning Tree Protocol PDU is tunneled; if the 'eoam(3)' BIT is set, then the ethernet Operation, Administration and Maintenance PDU is tunneled; if the 'lldp(4)' BIT is set, then the Link Layer Discovery Protocol is tunneled. If the bit for a given protocol is set for an interface, then the statistics for that interface and protocol will start to be monitored.
