Super-vlan : Achieve two-layer isolation, three-layer interoperability; all the Sub-vlan all three-tier communication needs to pass Super-vlan this gateway to implement; in a large network, saving IP Resources. VLAN communication can be achieved by simply configuring the Super-

Technology:is a Cisco FC Switch-specific concept, meaning that multiple Vsan traffic can be hosted via an ISL link, and Vsan resembles a VLAN with an IP switch, enabling two-layer isolated secure access. Brocade FC switches are also known as zoning for similar implementations of isolation.Vlan/ethernettrunk Technology:Refers to the VLAN tag tag, to connect the h

This article is for forwarding, simple and clear, I like.The configuration steps for Trunk ports are as follows:A set of network requirements:1. SwitchA and SwitchB with trunk interconnection, the same VLAN between the PC can exchange visits, different VLANs between the PC to prohibit mutual visits;2. Between PC1 and PC2 in different VLANs, by setting the upper l

If we want to communicate between VLANs, we usually use the three layer switch or router sub-interface mode. Linux on the VLAN with Cisco switch relay connection, also can realize their communication with each other.Environment: RHEL 5.2 Minimized installation, physical NIC Eth1, trunk port connected as VLAN switch con

Switch Port vlan mode Ø the Acess port receives a packet to determine whether there is any VLAN information: If there is no vlan information, the PVID of the port is entered and the switch is forwarded. If yes, the packets are dis

[SwitchB-vlan200] quit Configure the link between Switch A and Switch B Because the links between Switch A and Switch B need to transmit data from both VLAN100 and VLAN200 at the same time, you can configure the ports at both ends as the Trunk port and allow packets from the two VLANs to pass through. # Configure the GigabitEthernet1/0/2 port of Swit
