    The "access link" is a physical connection from the router to the frame relay switch in a frame relay network. It has nothing to do with VLANs. On this "access link", the LMI protocol monitors the connection and let's us know if the virtual circuits between the router's is up. Hope this helps!!!

    In the sybex 640-607 book they give a brief explaination on access links affiliated with VLAN's. Can someone help me out?? I'm still a little bit unclear on its purpose.

    to the best of my knowledge, there are 2 types of links, access links and trunk links. trunk links carry multiple vlan info across switches and access links carry information for only one vlan. so trunk links would be fast ethernet links between two switches and access links would be a link carrying info for one vlan from a switch to that lan.

    Yes the sybex book is correct. You have trunk links and access links. Trunk links carry all VLAN info (by default). An access link carries only one VLAN. So basically links to PC's and servers are access links and links to routers and other switches are trunk links.

    trunk links are fast ethernet port links such as 26 and 27 on 1900 series switches that ultilise VLAN tagging to identify which VLANs the frames propogating are from say if you have more than 1 VLAN on each switch in a multi switch network.

    access links have no affiliation with switching to my knowledge and are reserved for frame relay whereby the 'access link' is a leased line from the DTE ie router to the DCE ie frame relay switch and is managed by the LMI protocol 1 of 3 types cisco ansi or q933a LMI type.

    does that help at all?

    "Access-link" is used in frame-relay terminology, BUT it is also used in VLAN terminology. Check out the 7th question at the end of this document http://www.cisco.com/univercd/cc/td/doc/cisintwk/ito_doc/lanswtch.htm#xtocid4

    ur correct wow ive never heard of an access link on switching although it seems viable terminology for a standard link between switches or nodes that carry only single vlan info so would a switch with default setup for VLANs like just utilising VLAN 1 as default mean that all ports would be just access links and not trunk links?
