A switch with VLAN 200 converted into a PRIVATE VLAN with one P-Port, Two I-Ports in Isolated VLAN 201 (Secondary) and Two Community VLAN’s 202 and 203 (Secondary) with two ports in each. The switch has one Uplink Port (Trunk) connected to another switch and one P-Promiscuous connected to Router.

2014年7月4日 · Each VLAN creates its own broadcast domain in 1 or more physical switches. If you have a switch taken out of the box it tends to put all ports in vlan 1 so for say a 24 ports the broadcast domain includes all 24 ports.

2017年1月30日 · Yes. VLAN 1 is the default VLAN. You can have only that VLAN, or you could have a different VLAN. I was simply giving you an example of multiple VLANs because you asked how to create VLANs. It is the same as on a switch. –

Some switches even let you group ports into a virtual smaller switches (bridges) without the use of VLAN. In this case you run 1 subnet on top of a VLAN. VLAN is for the convenience of management.

Actually in vlan header contains TPID(16 bits),PCP(3 bits),CFI(1 bit)and VID(12 bits). in vlans we are using vlan id's for transport of traffic from one switch to another switch. so the vlan id i.e vlan identifier is 12 bits.

2024年11月1日 · Hi @haiqalshii !. You must verify if there is a communication between DSW devices (HSRP packets). If both devices are "HSRP active" for a vlan or the traffic of PCs have to pass for a Blocled port, then, the STP is the issue and you must elect another election of Port Roles to avoid the block of HSRP packets or traffic of PCs.

2016年5月20日 · device 1 => VLAN 1; device 2 => VLAN 2; Internet => VLAN 3; Then, to prevent them from talking, I could allow traffic between vlan 1 and vlan 3, as well as traffic between vlan 2 and vlan 3.
