An access port can only carry traffic for a single VLAN. A trunk port can carry traffic for many VLANs.<br />
<br />
What kind of switch is this?

Is there only the one VLAN or do you have multiple VLANs?<br />
<br />
Can you post the config of the switches.

I have two switches (A, and B) created with same VLAN name of alpha, for fault tolerance B will be a backup to A. <br />
<br />
I have a pc on Switch B connected to a port on &nbsp;alpha VLAN which can ping the firewall in Switch A, the firewall is connected to the untrusted port. But the PC from Switch B cannnot ping anything in VLAN alpha of switch A. <br />
<br />
Does anyone have a solution? <br />

Network Operations includes asset management, help-desk supervision, security and user policies, infrastructure administration and anything else that affects the operation of your network. Discussions will include those of best practices in platforms, configurations, performance, security and accounting.

Network Operations

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Switches / Hubs

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
