Link control protocol lcp is the core component of pointtopoint protocol ppp network communication. Link aggregation adtran aos supports link aggregation, which is defined in ieee 802. Iap220 series supports link aggregation using either standard portchannel configuration based or link aggregation control protocol protocol signaling based.
There are two methods used to start the link aggregation function, the static method, in which each each network device is instructed directly, and the dynamic method, in which the function is started dynamically using the protocol called link aggregation control protocol lacp. Lacp enables a network device to negotiate an automatic bundling of links by sending lacp packets to the peer. Many managed switches have an upper limit of 4 or 8 ports in an 802. Stp blocks redundant links whereas etherchannel can be used to provide redundacncy i. The functioning of link aggregation protocol is similar to port aggregation protocol along with ethernetchannel because it applies to multiple owner environments and it works on cisco devices as well.
