Hello Dear Team of network lessons.
I have a cisco switch 3560.
When I want to plug my Cisco IP phone to its’ port 10 Gigabit, 12-Gigabit then it shows not connected please see the output, to other switches shows up and connected only to Cisco IP phone it’s mentioned ports shows not connected.
Cisco IP phone model: CP-8845
Please note that to other ports my phone is working and all the ports are in same VLAN, same speed, and same protocol, and there is no port security issues.
Thanks in advance for the help and support.
Regards,
Ajmal Ahmady
