Synapses are composed of three main parts: 1  The presynaptic ending that contains neurotransmitters. 2  The synaptic cleft between the two nerve cells. 3  The postsynaptic ending that contains receptor sites.
Link aggregation is a feature that is used to combine a number ofports together to make a single high-bandwidth data pipeline. Theswitch treats all ports in a trunk group as a single port.TheDES-3526/DES-3550 can support 2-8 ports in a trunk group.ink aggregation is a feature that is used to combine a number ofports together to make a single high-bandwidth data pipeline.

From Wikipedia, the free encyclopedia. Port Aggregation Protocol (PAgP) is a Cisco Systems proprietary networking protocol, which is used for the automated, logical aggregation of Ethernet switch ports, known as an etherchannel. This means it can only be used between Cisco switches and/or switches from licensed vendors. A similar purpose protocol known as LACP, released by the IEEE known as 802.3ad, is an industry standard and is not tied to any specific vendor. PAgP can be configured on a Cisco switch to operate in three different modes.
