How to connect Extremenetworks Summitx150 to a 3Com 5500G series

Today I learn a lesson that if you want to connect a Extremenetworks switch(SummitX150) to 3com 5500G series via layer 2 please remove pvid vlan management. Let say if your extremenetworks switch contain 2 vlan example vlan 2 is for pc and vlan 3 is for network management i.e. for remote access via telnet or ssh. What you need to do is to remove the pivd vlan in the interface that directly connect to extremenetworks switch.

Function of Network Switch

In home networking, hubs and switches are technically only there for the cable network. Wi-Fi routers include built-in access point that is roughly equivalent to moving the cable.

In the telecommunications network, the switch is a device to channel data from multiple input multiple ports for input into a specific output port that will take the data to the destination. In the traditional telephone network switching circuit, one or more switches are used to create a dedicated connection, either temporarily or circuit for an exchange between two or more parties.
