Uplink port and tagged and untage VLANs

#1

Hello,

Two Qs:-

In one of the network setup, SVI interface and Router, are connected. What is the uplink port and what’s the MAC address of uplink port ? - Is it the port on Router attached to SVI interface OR is it a SVI interface towards Router port ? How can we find the MAC address of uplink port ?

We know that a trunk is a channel, to allow traffic to flow between two different switches that are part of same VLAN. ANd it is tagged with 802.1Q (by default). What is tagged and untagged VLANs ?

Thanks!
