Hello all
I have a question.
switch model : ws-c2960x-48ts-l
Configuration
- user device is connected to switch. user device use DM9161A(davicom semiconductor) Phy.
- switch setting
switchport access vlan 10
switchport mode access
speed 100
duplex full
no cdp enable
spanning-tree portfast
problem :
1) switch and user device's link status is up(100M/full)
2) switch don't receive packet that user device transmitted
* input packet count : not increase (show interfaces interface_name)
* input error : not increase (show interfaces interface_name)
* user device's mac is not learned at switch's port (show mac address-table)
* switch have no error disabled status. (show interfaces status err-disabled)
3) user device receive packet normally that switch transmitted.
4) if user device is connected to other device directly without switch, it works well.
5) also, if user device is connect to other small switch(only L2 switching function), then small switch is connect to cisco switch, it works well
Can you help me what is wrong ?
or what do user device have a problem.
please help me.
