Wireless Lan Controller

please can someone tell me. 

LAG - Link Aggregation

in Wireless lan controller. 

Why ? 

Benefits ? 

[Leo Laohoo]

Benefits ? 

Redundancy, period.

[jain.manish94]

The interface is attached to a LAG.
Enable Dynamic AP Management

please can you tell me in details , there is one option in wlc 

the interface is attached to a LAG. Enable dynamic ap management. what does it mean.

[Leo Laohoo]

Enable dynamic ap management

The use of "dynamic AP management" is old school.  Since the introduction of the 2nd Generation of WLC, 2504, 5508 & WiSM2, there is no longer the need for this.  

Where did you find this?  

the interface is attached to a LAG. 

Read THIS.

[jain.manish94]

on WLC Model 5508

[jain.manish94]

But here 

Physical Information
The interface is attached to a LAG.
Enable Dynamic AP Management

what is the benefits of Dynamic AP Management because it is here. 

[Leo Laohoo]

But here 

*Sigh*

Where did you find this?  What publication?  What documentation?  Due to the limited information provided we need to know whether or not the design is valid or out-of-date (or even borderline "crazy").

i have this info wlc model 5508 please can you tell me other things how to check .

[Leo Laohoo]

i have this info wlc model 5508 please can you tell me other things how to check .

Ok, I'll refrain from making other responses until I get more information. 

[jain.manish94]

ok , please can you tell me about anchor controller...

[jain.manish94]

what does this mean

• When i enable LAG, all dynamic AP-manager interfaces and untagged interfaces are deleted, and all WLANs get mapped to the management interface.

[jain.manish94]

Hello 

please can someone tell me that what does mean of 

I have found some of the failure logs on Primary ACS due to EAP Request timeout. I have fine tune the EAP parameters on WLC.

what is the meaning of red underline please reply me.

Link aggregation (LAG) is a partial implementation of the 802.3ad port aggregation standard. It bundles all of the controller’s distribution system ports into a single 802.3ad port channel, thereby reducing the number of IP addresses needed to configure the ports on your controller. When LAG is enabled, the system dynamically manages port redundancy and load balances access points transparently to the user.

LAG simplifies controller configuration because you no longer need to configure primary and secondary ports for each interface. If any of the controller ports fail, traffic is automatically migrated to one of the other ports. As long as at least one controller port is functioning, the system continues to operate, access points remain connected to the network, and wireless clients continue to send and receive data.
