Distributed trunking interconnect protocol

Distributed trunking uses the distributed trunking interconnect protocol (DTIP) to transfer DT-specific configuration information for the comparison process and to synchronize MAC and DHCP snooping binding data between the two DT peer switches.


For DHCP snooping to function correctly in a DT topology, the system time must be the same on both switches, and the ISC must be trusted for DHCP snooping.
