Cisco 2960 Switch Uplink issue

[zeenatkhattak33]

Hai

I have issue on two access Cisco 2960 switches connect to Ruckus icx7150 by TRUNK port. Cisco's 2960 port blinks Amber even if I remove the cable,, while same connect port on Ruckus is down. If I reboot the Cisco's 2960 for some time its working fine but again after 10 to 15 minutes...same happens.

Can anyone help to resolve.

 - At the time , when this happens check the logs on the Cisco (show logging) or (preferred) use a syslog-server, see what comes up. Same applies for  the Ruckus device (commands to check logs are probably different)

if it is blink amber even though no cable connected, can be a issue in switch. try with different port with same configurations. check console logs for activities when cable connecting to switch to find out what's happening. 

sometimes spaning tree may blocking port. or port going to error disabled mode due to some issue. easiest way to detect is check console logs.

Dear I tried the same by changing to another port..Same occured on the other ports also.

what is the configuration on that port ? Looks like (my guess it is doing some spanning tree)

[zeenatkhattak33]

There are no redundent link only one uplink is configured as trunk...how Stp is blocking sir?

[balaji.bandi]

we are not sure what is configure on bot the device, we are discussing hypothitically here what may be wrong  (in the  dark)

.how Stp is blocking sir?

i did not mentioned STP Block, this may spanning tree convergence, but that is my guess.

Hello,

hard to say what is going on. What switch configuration profile are you using on the Ruckus, the default one, or a customized profile ?

Post both the Ruckus and the Cisco configs, there could be a (e.g. spanning-tree) mismatch.

[zeenatkhattak33]

Dear on both switches just trunk configurations are done.

Conditions: When "Energy-Efficient Ethernet" feature enabled on both Catalyst 2960X switchport and on the PDs. Affected images: c2960x-universalk9-mz.152-2.E.bin c2960x-universalk9-mz.150-2.EX5 Workaround: Disable Energy-Efficient Ethernet (EEE) by below CLI command: 2960X(config-if)#no power efficient-ethernet.
