6850E Port Security Issue

[dmendj]

Hi Experts,

I am having a problem with my network. I have 6850E stack with two switches. I have a several Linux servers. The servers have 2 links connected to the stack (switch 1 and 2). I need to enabled port security so I have done below..

port-security shutdown 10 learn-as-static enable no-aging enable
port-security 1/33 admin-status enable
port-security 1/33 maximum 2
port-security 1/33 max-filtering 0
port-security 1/33 violation shutdown

port-security 2/33 admin-status enable
port-security 2/33 maximum 2
port-security 2/33 max-filtering 0
port-security 2/33 violation shutdown

I have dine the same to all other ports as well. but once port-security enabled I am getting timeouts on my network. I have not created Linkagg on those ports. Any idea.... For NIC teaming do I need to create LACP or static LAG ???

Hi,
mostly no linkagg is the best solution - the server decides how to handle the traffic.
lacp needs the same 802.3ad also at the server. You can try with static lag - but I haven't seen succesfull installation to servers with it.
You can also try to deactivate lps at this both ports for a time to see the difference.

Port Security is not supported on Link aggregate ports......
