Where is edge ports in this document

Question

1. is the edge port means the port of distribution layer switch which connect to the access layer switch?
2. there are only switch and routers, what servers fail to boot up ? will access layer switch or distribution layer switch or core switch fail to boot up?
3. where to set individual state? is it the edge port?
4. does below mean that "no lacp suspend-individual" command can solve the problem of switch not boot up?
http://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/4_2/nx-os/interfaces/configuration/guide/if_nxos/if_portchannel.html#wp1704172
should only run the lacp suspend-individual command on edge ports
1. config t
2. interface port-channel number
3. shutdown
4. no lacp suspend-individual
5. no shutdown
6. copy running-config startup-config
By default, LACP sets a port to the suspended state if it does not receive an LACP PDU from the peer. In some cases, 
although this feature helps in preventing loops created due to misconfigurations, it can cause servers to fail to boot up as they require LACP to logically bring-up the port. 
You can put a port into individual state using the lacp suspend-individual command.

Hi,
1. is the edge port means the port of distribution layer switch which connect to the access layer switch?
No, absolutely not. An edge port is a port connected to a device that is by its design or configuration incapable of performing Layer 2 switching or bridging. Devices such as routers, servers, end hosts, network printers, network attached storage, webcams, etc., these all do not perform Layer 2 switching and therefore ports to these devices can be configured as edge ports. Devices such as switches, hubs, wireless bridges or autonomous access points are performing Layer 2 switching and ports toward these devices are non-edge ports.
To put it very simply, whenever a port on a switch is connected to another switch, that is a non-edge port. If a port on a switch is connected to a non-switching device, such as router, server, or an end host (a PC, a workstation), that is a candidate for an edge port.
2. there are only switch and routers, what servers fail to boot up ? will access layer switch or distribution layer switch or core switch fail to boot up?
I am sorry, I do not understand this question. Please try to ask in different words or perhaps provide an example.
3. where to set individual state? is it the edge port?
Edge ports can be configured in two ways:
Either directly on the port that should act as an edge port using the spanning-tree portfast command
Or in the global configuration using the spanning-tree portfast default command that will automatically make all access ports, both current and future, to be considered as edge ports
