Configuring Access and Trunk Interfaces
Configuring Access and Trunk Interfaces Ethernet interfaces can be configured either as access ports or trunk ports. Trunks carry the traffic of multiple VLANs over a single link and allow you to extend

The trunk link from the first switch to the router can also carry all four VLANs. In fact, this one connection to the router allows the router to appear on all four VLANs, as if it had four different physical ports
Using fiber optic links as trunk between switches.
They have both POE and Non-POE Versions and they have 4 - 10G SFP+ Slots that you can use to uplink your switches. An example would be the Cisco SG500X-24p, They also offer

Port Configuration The default port configuration is Auto, which enables a port to sense speed and negotiate duplex with an auto-enabled port on another device. Switch recommends that you use the

To accomplish this, configure some ports as access ports of the new VLAN and the uplink port as the trunk port, which also passes the new VLAN traffic along with
Access and Trunk Ports
Trunk ports are used to connect switches to each other, which allows for the creation of a larger, more flexible network. Trunk ports can carry traffic for multiple VLANs, which provides greater
how many trunks are allowed in a switch
If the ports membership can be determined from the switch configuration then that could ensure frames from one vlan do not leak into another. So there does seem to be a reason to use the
VLAN Configuration Guide, Cisco IOS XE 17.16.x (Catalyst 9500 Switches)
Trunk ports can be grouped into EtherChannel port groups, but all trunks in the group must have the same configuration. When a group is first created, all ports follow the parameters set for the first port
Configuring VLAN Trunks
You can configure parallel trunks to share VLAN traffic by setting different path costs on a trunk and associating the path costs with different sets of VLANs, blocking different ports for different VLANs.
Configure and verify trunking on Cisco switches
You can resolve this problem by first checking the trunk port on the switch using Show interface trunk command and the reconfiguring the trunk port using the switchport trunk allowed vlan command.
