Switch into multiple Networks

[UKDanny666]

Hi fellow Ciscoers

Is it possible to connect a CAT 9300 switch into two networks?

This will be a guest wifi switch, so traffic will be on the guest network 172.16.x.x, I would like to monitor the switch from the corporate 10.x.x.x network.

The switch itself forwards all traffic to the guest router. Will the managment port work with this? i have been reading this article https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst9300/software/release/16-6/configuration_guide/int_and_hw/b_166_int_and_hw_9300_cg/b_166_int_and_hw_9300_cg_chapter_010.pdf, the way I understand it is if i put an IP address from the 10.x.x.x range on the managment port this will allow me to monitor this from the corporate LAN. If i do this will the managment port of the 9300 appear as a switch and ERR-Disable the port on the access switch I will need to connect it into? or does this appear as a normal NIC?

Thanks in advance

Can you post the configuration of that port,

Hi,

There is no config just yet, this is purely theory currently. I need to order the hardware and just seeing if this is the best course to go down.

Thanks for the reply.

Yes it can

basically the switch does not even need to know about IP adresses in the 172.16.x.x network

you create a VLAN to forward packets on Layer-2 (not Layer-3) between hosts and guest router.in this network

and configure ports in this vlan to connect them

as such the switch also DON't need a route to the guest router.

and YES you can monitor the switch from your 10.x.x.x network
