slow browsing

[kp-tkr2014]

Hi,

I have the below topology 

wireless users were experiencing slow browsing.  So I started to shut down the interfaces between core and distribution.

So when I shut down the interface   10g (L3 ) on the right side  , problem almost solved 

My question is  why wired users did not experience this problem 

Thanks

check for interface stats showing any abnormality and switch logs. any loops.

first, allow only intended VLANs. check the LAG configs and if there any errors.

may be the issue local to wireless VLANs only on the isolated path.

Hi,

If I use the same vlan  wirless on  wired there is no issue .

I mean the same vlan if I assigned for wired access there is no issue 

Thanks

Check if the links between the Core1/2 and dist1/2 are correctly in a port-channel on both sides. Also check if the WLC port-channel is correctly configured (LAG mode): http://www.firewall.cx/cisco-technical-knowledgebase/cisco-wireless/1223-how-to-configure-wlc-lag-and-port-channel-with-nexus-catalyst-switches.html

Sounds a little as if only half the packets correctly arrive at the WLC if both dist1/2 switches are fully online.
