How to merge Cisco interfaces into one device on Zabbix?

Question

Cisco

Good day!
1) There is a Cisco 9300 on which 20 VLAN interfaces are created.
2) There is a Zabbix with a discovery rule that has several checks - one of them is the SNMPv2 agent "1.3.6.1.2.1.1.1.0" . Uniqueness criterion by IP address .
3) There is an action for discovery with conditions: If SNMPv2 agent "1.3.6.1.2.1.1.1.0" received value contains Cisco , then add to the group and apply the corresponding template.
Everything would be fine, but when detected, not only the device itself is added, but also all 20 VLAN interfaces as separate devices, but all have the same name.
Prompt how to overcome this muck, can somehow exclude these interfaces from SNMP on cisco?
Or what settings can be made on Zabbix so that it adds all interfaces to one device?

Answer 1

autodiscovery should only add chassis as host. And inside the host, inside the template, in the items, there should be auto-detection by snmp.

Answer 2

Make a discovery inside a template (similar to the search patterns for disks in a file system, for example).
