Cần giúp đỡ gấp hệ thống mạng không thể kết nối cũng VLAN

[mrh09]

Chào mọi người
Hiện tình em đang khẩn cấp nhờ các bác tư vấn giúp
Sơ đồ:

Hiện em đang gặp vấn đề như sau:
Em có: 3 PC (các bác có thể nhìn vào hình)
PCA (IP:172.16.2.31/24)
PCB (IP: 172.16.2.32/24)
PCC (IP: 172.16.2.29/24)

1.
PC A và PC B có thể nhận IP động từ DHCP Server (DHCP Server nằm trên con CoreSW 3750)
PC C thì không thể nhận được IP động từ DHCP Serer(DHCP Server nằm trên con CoreSW 3750) nên em đang đặt tĩnh.
2.
PCA có thể ping PCB và ngược lại
PCA và PCB thì không thể Ping đến PC C và ngược lại (mặc dù em đã đặt IP tĩnh)

3.
PC C em đặt IP tĩnh (không nhân được IP đông )thì có thể ping đến 172.16.2.1
PC A và PC B nhận được IP đông thì không thể ping đến 172.16.2.1

Đây là cấu hình con Core3750
