1.7.2 TPID Value Configuration Example
I. Network requirements
z
Switch A and Switch C are S9500 series switches. Switch B is a switch produced
by other vendor. It uses TPID value of 0x9100.
z
Two networks are connected to the GigabitEthernet 2/1/1 ports of Switch A and
Switch C respectively.
z
Switch B only permits packets of VLAN 10.
z
It is required that packets of VLANs other than VLAN 10 can be exchanged
between the networks connected to Switch A and Switch C.
