Sorry, customer's policy don't allow it.

Almost configuration is factory default, and port/stp configuration is factory default.

Are both sides configured as an access ports or trunk port?

I didn't configure the ports "switch mode access" on both switches, so they operate in trunking (802.1q)


Cat2950  only support 802.1q
