Ask for advice: Cisco switch interconnection port encryption or authentication
Consult: the two existing offices are far away, connected by Cisco switch fiber (3750 and 3560). For security, if you want to encrypt or authenticate on the two switches, can you encrypt on the interconnection port of the two switches without affecting the traffic of other ports? For example, the client of one switch can obtain the IP of DHCP connected to another switch. I read on the Internet that macsec and trustaec can be implemented, but I don‘t know how to configure them. Please give me some advice.
