You will issue commands to display the MAC addresses on a PC and a switch, and analyze the properties of each one. Step 1: Analyze the MAC address for the PC-A NIC. Before

The MAC-based VLAN classification enables packets to be classified according to their source MAC address. You can then define MAC-to-VLAN mapping per interface. You can

Sorry for the ambiguity, What I was trying to do was to setup multiple virtual interfaces on one machine with a single NIC.When I connect a switch to my modem it assigns one IP address to

In switch supports independent vlan learning, same mac-address can be learnt on different vlans. while mac lookup is based on vlan-id + dst-mac. In case of shared vlan learning

To debug the issue, you can use the following commands to check the MAC address table and why frames are being dropped: show mac address-table: This command displays the MAC address table on the switch, including

Each NIC (wired, wireless, etc) on a computer has a different MAC address. Given that a computer can have more than one Ethernet card (or whatnot), and ignoring the fact that

Devices that were formerly working, suddenly will not get an IP address from DHCP. If I plug a known working device into that port, it also will not obtain an IP address. Other devices on the

Table 1: Since IP addresses can be assigned to individual NICs by the user, it is possible to assign similar IP addresses to a group of interfaces and then easily determine

Search results on this topic lead me to the solution that both VLAN interfaces require to have a different MAC address. The original modem/router showed that the IPTV

As MAC-address is built in on port NIC. MGMT SVI will have different MAC address. Port will use it’s own MAC for STP calculation – e.g. when there is equality in all

For example if the bridge connects 2 trunk interfaces and the same MAC addresses may be seen from both interfaces, depending on the VLAN. As the Linux bridge does not support VLANs

If your VLAN (broadcast domain) is so large that a switch is running out of space for the VLAN MAC address table, it is time to reduce the number of switch interfaces in the

Is it possible to change mac address on virtual NICs associated with VLANs created under Windows 10 using last Intel drivers for i210? I cant find the way to do it. Thanks.

Each VLAN can have its own IP address range, and routers can be used to route traffic between VLANs. Another option is to use a NAT (network address translation) device.

I am having a problem with several workstations not being able to access the network. Upon further investigating I found that the MAC address is appearing on different

Proxmox assigns different MAC addresses to each VM/CT, so they’re treated as discrete NICs on the network and should each have their own IP address (assigned by DHCP or static in the

Sun Sparc systems had all NICs on the same MAC address. This gave no end of trouble when plugging more than one NIC into the same switch (e.g. with different VLANs).
